Alexander is visiting Boston after the Open Hardware Summit last week in
NYC.   We powered up the umTRXv2 for the first time yesterday afternoon and
immediately captured a GSM signal on the Signal Hound after launching
OpenBTS.     Echo Test with the test handset worked like a charm.
Congratulations to the Fairwaves team!

Robin,


I've been at a couple of " Commodities Houses " here in Chicago explaining
to them both about me efforts in creating a  Commodity Exchange, as well as
the technology I shall be putting into place.  Namely, the UmTRX will be
the communications systems I utilize :)

Eagerly awaiting!

Sincerely,



Martin

Hi All,

I ported UmTRX project to the new UmTRX v2 board. Now you can compile FPGA
project for UmTRX v2 board with "make UmTRXv2" command from fairwaves/umtrx
branch.
Now, my next goal is to get a working second transmission channel in fpga
project.

Martin,

If you speak about US, then I doubt this is hardly possible to deploy
OpenBTS/UmTRX in an easy fashion because of the spectrum regulation. All
GSM spectrum belongs to big carriers and they won't allow you to use it.
The only way to go I'm aware of is to setup an MVNO with one of the
carriers, but this is extremely hard to negotiate and requires a good pile
of money.

Andrey, Jean-Samuel,

I wanted to check pricing for ET1011C2-CI-DT - 1GbE PHY chip we use
and I haven't found it neither in DigiKey, nor at Mouser. At Arrow
they are "Call for Quote":
http://components.arrow.com/part/search/ET1011C2

Do you know what happened to this chip? Is there any pin-to-pin
replacements or could we buy enough of those chips from some other
source?

Interesting, yesterday it was out of stock.
So this is good news, seems they re-stocked ET1011C2 meantime.

Subject: LPF Bandwidth Tuning with LMS6002
Message-ID: <BAY002-W133D3BFD9302A91E47697108D880@phx.gbl>

Hi,
I'm having a problem while trying to do a LPF Bandwidth tuning as described in a Programming and Calibration guide page 40, figure 4.5 and on https://github.com/chemeris/UHD-Fairwaves/blob/fairwaves/umtrx/host/utils/umtrx_lms.py#L433. Currently it seems to always fail when it's trying to find the VCOCAP value. I'm only getting Low printed before it fails. I was wondering why it takes a 320MHz frequency, because it's not described anywhere in the documents, could I try to do a bandwidth tuning with some other frequency as well? I'm running my code in a following order (http://lists.osmocom.org/pipermail/umtrx/2012-July/000075.html),

Example setup for ARFCN 925:

Initialization and auto-calibration:
  ./umtrx_lms.py --lms 1 --lms-init
  ./umtrx_lms.py --lms 1 --lms-tx-enable 1
  ./umtrx_lms.py --lms 1 --lms-rx-enable 1
  ./umtrx_lms.py --lms 1 --pll-ref-clock 26e6 --lpf-bandwidth-code
0x0f --lms-auto-calibration

RX LNA and RXVGA2 selection and gain control
  ./umtrx_lms.py --lms 1 --reg 0x75 --data 0xf0
  ./umtrx_lms.py --lms 1 --reg 0x65 --data 10

TX LPF control
  ./umtrx_lms.py --lms 1 --reg 0x34 --data 0x3e

LO leakage cancellation (calibration data values may vary)
  ./umtrx_lms.py --lms 1 --reg 0x42 --data 0x67
  ./umtrx_lms.py --lms 1 --reg 0x43 --data 0x89

TX/RX PLL charge pump current
  ./umtrx_lms.py --lms 1 --reg 0x16 --data 0x93

Tuning
  ./umtrx_lms.py --lms 1 --lms-rx-pll-tune 925.2e6
  ./umtrx_lms.py --lms 1 --lms-tx-pll-tune 880.2e6

TXVGA2 gain to max and enable PA
  ./umtrx_lms.py --lms 1 --reg 0x45 --data 0xc8
  ./umtrx_lms.py --lms 1 --lms-pa-on 2

Hi,

For LPF bandwidth tuning, TXPLL generates 320MHz which is on chip 
divided by 8 to construct 40MHz reference frequency to tune RC product. 
Using any PLL frequency other than 320MHz will result in wrong tuning 
reference frequency i.e. wrong RC tuning code.

The question is why VCOCAP search fails while setting TXPLL to 320MHz. 
That should not happen.

Hi Gillian,

So, I see you've ported umtrx_lms.py to the board you're using? If you
want to share your port with the community, I'm happy to merge your
changes to our git. I think we could even create a separate git repo
for umtrx_lms.py in this case.

Regarding your question. It might help if you post here output from
umtrx_lms.py and umtrx_ctrl.py at the maximum verbosity (say, 10). The
value is set at the top of the files for now. In general, I think you
should check that you've enabled proper blocks in LMS and enabled SPI
clocks for them. If this doesn't work - check with the manufacturer of
your board. I have no idea which board do you use, but the
manufacturer may have intentionally or unintentionally break tuning
abilities of the chip,

Andrey Sviyazov, this question is probably for you,

IIRC, both nanoBTS and SysmoBTS have separate antennas for Rx andTx and do
not use duplexers. Do we need duplexer for UmTRXv2 if it operates in the
low power mode, without an additional PA/LNA?

Hi Alexander.

If Tx level very small and Rx path not  saturated, than you should check Rx
noise flour to be sure that TX doesn't jumm Rx.
Anyway it all about Rx sensitivity only.

Andrey Sviyazov.

Note that both still have internal filters.

Antenna design also plays a role. The nanoBTS uses patch antenna
separated by a lump of metal to minimize direct radiation from TX to
RX.

You mean bandpass filters? Are they only on Rx side or both Tx and Rx?

Yes, I remember that nanoBTS has patch antennas for better isolation.
But IIRC sysmoBTS has rubber duck antennas which made me wonder how do
they do Tx/Rx isolation.

Yes, bandpass filters. (SAW or Ceramic, possibly both)

nanoBTS has both side. You can clearly see them here :
http://openbsc.osmocom.org/trac/wiki/nanoBTS/Internals
sysmoBTS I know has RX filters, I don't remember about TX.

Mine actually shipped without antennas :p

I use it with rubber duck in lab tests but I don't know if it's a
recommended configuration.

Hum, I don't see how is that different from a duplexer if they have
both Rx and Tx filters. Do you know any particular reason for this
design?

It still exposes independent TX and RX lines allowing for external
amplification / filtering if required.

Also in a duplexer you have a direct electrical connection rather than
TX->RX radiation which means you need much more attenuation (often
requiring the duplexer + subsequent band pass filters).

Subject: LMS6002D support of LTE
Message-ID: <CABmJbFWA5gdzfVio32CAa_ar2uJUQa3_wz88m2kBuzr=b5w8-g@mail.gmail.com>

Hi Srdjan,

We're looking into re-purposing UmTRX for LTE and there a few things which
we need to understand better.

1. Is it possible to support 15MHz and 20MHz LTE channel bandwidths? To
achieve this we at least need to sample at 23.04Msps and 30.72Msps
respectively. LMS6002D datasheet specifies the maximum I/Q samplerate of
14Msps, which is not enough. But at the same time, datasheet claims that
ADC and DAC are specified up to 50Msps. How does this fits together?

2. Do you have any experience what maximum output power we could achieve
with LMS and proper amplifiers, while still staying in the bounds of the
LTE Standard? What would be the limiting factor for the further power
increase?

3. Is there any issues using TDD mode in LMS6002D? We've been using onnly
FDD mode so far and it would be great to know what issues could we expect
when switching to TDD mode.

Alexander,
Can you provide a reference to where the datasheet calls out a max I/Q
sample rate of 14 Msps?  The analog low pass filters support a max
bandwidth of 14 MHz (which leads to 28 MHz RF bandwidth assuming
zero-IF operation)...is this what you're referencing?  We run the A/D
converters in the LMS6002d at sample rates greater than 14 Msps all
the time, including 30.72 Msps.

The datasheet is not very clear on this topic. I'm referring to the
following line at the Table 1:
Baseband Bandwidth       14MHz

Originally I read this line as "digital I/Q bus has limitation of
14Msps" and this is what confuses me.

Just to be sure - do you mean you feed RX_CLK and TX_CLK of LMS6002D
with 61.44MHz clock? It's divided by 2 internally, so if you feed them
with 30.72MHz clock you actually get only 15.36Msps out of LMS6002D.

Does  this mean you are moving away from GSM, or you just trying to make

Correct, when running the A/D at 30.72 Msps, the RX_CLK signal needs
to run at 61.44 MHz.

Yes, we're exploring the possibility of doing LTE with UmTRX, as we may
start working in this direction sooner then we originally planned. We will
continue to work on GSM in any case - we believe that GSM+LTE networks are
the winning combination.

Ok, thanks for the clarification.

Great!
In case you know a good 61.44 MHz oscillator with a reasonable price -
I would appreciate a pointer.

Something like the attached Taiten VCTCXO @ 30.72 MHz + ADF4002 Phase
Detector/PLL synthesizer might work.  I have no idea how much the
oscillator costs.  (The Pletronics oscillator on the UmTRX and the
GAPfiller GSM900 isn't available at this frequency.)

Hi Robin,

Do you mean to use ADF4002 to double the frequency?

Right now I want a simple solution - just replace the TCXO on UmTRX
from 26MHz to 61.44MHz and see how it works. Doubling the frequency
would require PCB rework and is possible for the next generation of
UmTRX only.

Hum, good idea for the very first try. We should try this out this week.

But I still want a normal TCXO/OCXO replacement for UmTRX to make it
easier to rework more UmTRX boards.

Hi Alexander,

You can simply replace 26MHz TCXO with foot print compatible 61.44MHz 
TCXO. Divide by 2 would be required to construct PLL reference below max 
41MHz (61.44/2 = 30.72MHz) while having IQ interface still running at 
61.44MHz which corresponds to 30.72MS/s converters sample rate. This is 
something we usually do with LMS eval board when customers want to 
evaluate more bandwidth demanding modulations such as 20MHz LTE.

The limiting factor here would be absolute specs on ACPR, out of band 
spurs ... i.e. TX spectrum mask, expressed in dBm not in dBc. For 
example, you may meet <= -45dBc ACPR but on the other hand you can not 
inject noise into adjacent channel more than xdBm. LMS device is OK for 
20-25dBm modulated output power. We can probably push it more however 
this is  not tested so far.

TDD mode should be just fine. We measured around 20us TX<->RX switching 
time. We will probably need to reconfigure VCO supplies on UmTRX board 
to simplify switching control while keeping switching time at 20us. Lat 
us know when you are ready for such experiment.

Hi Srdjan,

Doh, I completely forgot that we would need to divide by 2 for PLL if
we install 61.44MHz clock.

Andrey Sviyazov - I think we don't have a way to divide PLL clock on
UmTRXv2, right? If so, for LTE sample rates we're limited by 30.72MHz
on UmTRXv2.

Utilities from UHD are working properly. However, the OpenBTS crashes at
startup. Now step by step I connect each block and try to find what causes
instability.

What do you mean by connecting blocks? I thought it's the problem with
registers of the DSP block in FPGA.

The problem is not in the registers, but the fact that the second unit does
not give  the first unit to work, or vice versa.
Somewhere I made a mistake. I think so ..

Since we decided to make version 3 (due to additions of  LMS thermosensors)
then we can also add external Fref prescaler for PLL, no problems here.
I think ICPR is more important restriction.
Srdjan said that it doesn't studied too deeply, but on my opinion, really
reachable maximum Tx power no more then 25 dBm (without DPD).
So, we can't use LMS for LTE without DPD or additional filtration (2nd Tx
IF).
In other hand, we can implement it similar to UmSEL and with upconversion,
of course, but high quality SAW filter required (all flatness) to keeping
EVM as small as possible.

Best regards,
Andrey Sviyazov.

DPD will linearize PA, LMS should not be limiting factor in that 
respect. In band spurs should be investigated before we say that LMS can 
or can not be used. What output power are we looking for?

Hi Srdjan.

Thank you for reply.
Our potential customer asked us about TDD with 43dBm at antenna port and
with as  many of MIMO's as it possible (theoreticaly) to realize now to get
higher users density per sector. Of course, for the first look it seems
like an dreams, but it is true real customer dreams.
So, now we have to understand real LMS performances for LTE anyway.
It required to be able to answering customer either something about
0.1-0.5W and no more or to start good real project with required specs.
Please suggest us something to answer.

Best regards,
Andrey Sviyazov.

Regarding TCXO frequency.

I think we're not going to release UmTRXv3 immediately, as UmTRXv2
works well for GSM. If I remember correctly, we planned to connect
temperature sensors to unused debug pins on UmTRXv2 or to extension
connector together with UmSEL daughter-board. Meantime, I want to be
able to test LTE with UmTRXv2 and thus my question was which maximum
TCXO frequency we could use. It seems like the answer is 30.72MHz,
because we don't have prescaler for PLL.

Hi Srdjan.

As I understand, I must to re-ask and much simpler and more correctly:
Do we need to search another components for LTE BTS with MIMO/20MHz/10-20W
or there are chances to use LMS6002?
You told about 20-23dBm output power, so please let us know what PA do you
use in this case.

Best regards,
Andrey Sviyazov.
P.S.
Sorry for my undeveloped english :)

Message-ID: <CABmJbFVyEuwysjZuLrHXg1BnspUBsBD1_8YioOvVufcgqembcg@mail.gmail.com>

Hi all,

We're thinking about making T-shirts with open-source telecom. I've
posted a call for ideas in my OpenBTS blog - please contribute.
Telecom needs more openness and you could help us promote this!
http://openbts.chemeris.ru/2012/10/reklama-open-source-telecom/

We plan to give them for free to the first 10-20 UmTRX buyers. Then
you'll be able to buy them from our web-shop or from one of our
friends and distributors.

If you proposal gets printed, you'll get a free T-shirt as well.

PS If you know a good online T-shirt printing service in US or Europe
- drop me a line. I've never done this in US/Europe before.

Hello UmTRX list.   We've started a discussion about open source telecom
t-shirts.   From Alexander:

I think we should start making t-shirts to support open-source telecom
(and our project). I've posted a call for ideas in my Russian blog -
please contribute! In English too!

Just the first thought that popped into my head.  I'm not overly attached
to it.   I'm sure someone can up with a better visual representation of
Open Source Telecom.

Yes, background color.  I like white t-shirts too, but I always spill
coffee on them.  A slightly darker shade, say grey, masks stains.

Nice idea. The last symbol would be better to have in the form of a
SIM-card, imho.

Looks not so bad with perforated SIM-card.
Can we use OSHWA and OSI logos?

Nice picture!
I like it.

Yes, I think we could use those pictures. To be sure we have to check
with this document regarding the OSI logo:
http://opensource.org/logo-usage-guidelines
AFAIK, OSHW logo doesn't have such guidelines yet.

This logo was designed during the time of dispute between OSHWA and
OSI to avoid any resemblance with the OSI logo. Nowadays, when the
issue between OSHWA and OSI is settled, we could safely use "geaer"
OSHW logo. It's much more recognized and is the key to this
three-piece picture.

I actually like Andrey's version better.   It will look cleaner
silkscreened on a t-shirt.     I would also advocate for a slightly darker
shade of blue for the SIM card.

I like Christian's modification - it's more fun, imho.
But I think both versions have the right to exist - we'll see which
one wins the voting.

I prefer "Telecom wants to be Free" too.  (upper case F)

and I also prefer the sim to be vertical.


Just my 2c

I suggest "Unlock communications for the rest of us!" - just another option
bring to a vote.
Vertical SIM looks good, but it was difficult for me to arrange it with the
text. If somebody wants to play with it, I can provide vector (AI) files.
Superman style - good idea, previous versions of T-shirt was slightly
boring. So I propose make something informal at the back side.

Andrey.
You could add HARDWARE word, to align text with vertical Sim.

And about colors - why blue?
On my opinion, dark green and golden contacts looks better.
At least blue and gold is not good combination for me.
It looks like church painting.

"The rest of us" - is it some idiom? I don't get it.
I believe we need something everyone could understand.

Hmm, I missed it.
But really not sure that Fairwaves will associated to the blue colors (and
vice versa) due to the blue logo.
It doesn't mean that all around must be in blue.

Yes, it was bad idea. I've check it and in some cases it uses in negative
connotation.
(From the macintosh slogan "The computer for the rest of us") 1. Used to
describe a spiffy product whose affordability shames other comparable
products, or (more often) used sarcastically to describe spiffy but very
overpriced products.

I think the front of the T-shirt should read "FREE GSM" with the logo of a SIM card with little feet running. The back should have the Fairwaves Logo / URL. "FREE GSM" because it's a pun: free of cost thanks to open source, and free it from the shackles of the evil big black box infrastructure vendors. 

In terms of color, if a deep dark midnight blue (like Nike's "Obsidian" blue) would be awesome. This is for selfish reasons since all my gym wear is Obsidian blue :-) Oh and some T-shirts in European XXL or American XL would be nice for me.

It looks much better for me.
But you was right, horizontal Sim was better.
Also www.fairwaves.ru under fray line.

Hello all/list,

My humble versions/variations.

Perhaps a variation on the "Telecom wants to be FREE" slogan could be
"Fairwaves - we are OPEN 24/7" or "OpenTelecom - we are OPEN 24/7"

Cheers,
Andrei

Hi Jean-Samuel.

Pdet1&2 dedicated for Output power detectors and Vcnt1&2 for test points
voltage control.
For example, PA +24V and feeder supply voltage 28..36V of DC-DC converter
(in case of positive type, i.e. minus connected to chassis).
Each input of ADS1015 contains divider of 1:10, so it makes possible to
measure up to 41V with 0.01V resolution.

Best regards,
Andrey Sviyazov.

Hello all,

We are preparing for voting now and trying to use proposed slogans as they
were written. The only exception is the term "Open Telecom", we convert it
into "Open-Source Telecom".

"Open" is a very general abstract concept, while "Open-source" - very
specific. For example, Open Telecom could mean so-called "Open Standards",
so GSM, 3G, and LTE become Open Telecom in that sense.

Subject: Multicarrier OpenBTS on UmTRX
Message-ID: <CAF5FEsDD8_YdsUGEgP0CKkaBkWpYS91Qgw9Wre1tYHAd4TP1kw@mail.gmail.com>

Hi all,

I spent some time yesterday testing UmTRX with MCBTS. Aside from some
trivial fixes (inverted sample rate), the code ran fine with no
issues. The default bandwidth of the LPF was insufficient, so that was
widened. I tested with 9 handsets between 3 and 7 carriers on a Core2
Duo (P7570) laptop.

  git://github.com/ttsou/openbts-multi-arfcn.git umtrx

Configuration is through sqlite database, which is unchanged from
mainline; just set the number of ARFCN (7 max) and C1 channels.
Because of the bandwidth involved, be sure to increase the maximum
buffer sizes for UHD. The uhd_usrp_probe utility will warn if the
target size cannot be set.

  http://files.ettus.com/uhd_docs/manual/html/transport.html#linux-specific-notes

Design
=====
There are three resampling stages.

1. Outer resampler converts from the device rate to a multiple of the
400 kHz channel spacing.
2. Channelizer demultiplexes input stream to M channels
3. Inner resampler converts from 400 kHz to a multiple of the GSM symbol rate.

UmTRX rates:

Channelizer Rate   Device Rate  Decimation

   1.6 Msps            1.625 Msps         8
   3.2 Msps            3.250 Msps         4

Options
======

To broadcast dummy bursts on all carriers for spectrum testing,
uncomment the following preprocessor declaration in radioParams.h.

#define ENABLE_ALL_CHANS

With dummy bursts on all carriers:

  http://filebox.vt.edu/users/ttsou/http/7carrier_umtrx.PNG

Calibration
========

Calibration remains a concern. With single carrier, the carrier
leakage and and IQ imbalance appear as in-band distortion. For MCBTS,
OpenBTS offsets C0 on to the lowest carrier. This makes the carrier
and image quite visible, as shown in the following uncalibrated
capture. I checked with a swept tone to verify that this issue was not
a result of baseband DSP. The USRP also shows similar effects.

  http://filebox.vt.edu/users/ttsou/http/carrier_image.PNG

Any idea how much carrier and image suppression we should expect with
calibration on UmTRXv2?

  Thomas

Message-ID: <CABmJbFWwnpivfYEt6rZxD-Kw9C7=+AASc4y2LT3RF6eQzeBLhA@mail.gmail.com>

Hi all,

I've pushed an update to git to store some LMS6002D calibration values
in UmTRX's EEPROM. The idea is to  perform calibration once and do not
worry about it anymore no matter what PC you connect UmTRX to.

Intro
====

Right now we have the following values which could be stored in EEPROM:
 * tx-vga1-dc-i - DC offset calibration value for LMS6002D Tx I channel
 * tx-vga1-dc-q - DC offset calibration value for LMS6002D Tx I channel
 * tcxo-dac - TCXO calibration value

Now, when the framework for UmTRX EEPROM is in place, we could store
more values there as we see the need. E.g. we may want to store Rx DC
offset calibration values or power limits of this exact units to be
used by OpenBTS.

The only limitation here is the size of the EEPROM. EEPROM is only 256
bytes large and some of them are already used, so we have about 200
bytes to use. With the strong dependency of calibration values on
temperature and frequency, we might need a two-dimensional array for
each value. In this case we may want to move those calibration values
to flash instead of EEPROM. This would need some more work and thus is
in our wish-list for now.


Writing values
===========

You could write values mentioned above to EEPROM as any other EEPROM value:
  ./host/build/utils/usrp_burn_mb_eeprom --key <name> --val <dec_val>
  (from the root of your UHD source tree)

Reading values
=============

You could read individual values from EEPROM as any other EEPROM value:
  ./host/build/utils/usrp_burn_mb_eeprom --key <name> --val <dec_val>
  (from the root of your UHD source tree)

Or you could use `uhd_usrp_probe` to see them all at once at the
top-level section:

Subject: UmTRX power adaptor
Message-ID: <CABmJbFUQdMp5XgKD6_g2sAYNGMhdVgW_Bxt_NYAmiGxBq7hWaw@mail.gmail.com>

Hi all,

UmTRXv2 samples for early adopters should be ready in just few weeks
and we're looking at what to put an a package. Below is a preliminary
list of items which I think we should include. Please comment on the
list and suggest particular items:

 1. Power supply, 12V-18V DC, >=20W.
I think it's easier to find a PSU with a standard round DC connector,
like this one and thus we need a converter cable to our Molex power
connector.
http://domino2.kycon.com/catalog_PDF/KLDX_SMT2.pdf

 2. Converter cable from the Molex power connector to a standard round
DC connector.

 3. U.FL-to-SMA-F pigtail cable.

 4. Two small antennas - omni or patch. One for Tx and one for Rx.

Below is a list of items which are non-essential and which we unlikely
to include in the package for this batch. We do no have them ready yet
and we don't want to delay shipping.  We focus our effort on polishing
UmTRX and UmSEL performance and software development which we see as a
more important tasks at this moment.

 1. Duplexer. Without a power amplifier UmTRXv2 is pretty low-power
(50-100mW) and thus it works good enough without a duplexer in a
normal environment. For our testing we use two small antennas - one
for Rx and one for Tx without any issues.

 2. Enclosure. We'd love to have a nice table-top enclosure for UmTRX,
but it requires a significant effort to source, design and assemble.

 3. UmSEL. It's not clear whether we will have UmSEL production setup
in time. Software to control UmSEL is yet to be developed as well.
Since it's only an improvement frontend, I don't think we should
include it into the basic package.

If you want to help us make those items faster - by all means feel
free to offer your help! :)
 * If you provide a valuable contribution, you'll get the item you're
contributed to for free.
 * If you provide significant contributions on a regular basis, you'll
get all our future hardware versions for free and recognition on the
web-site.

And surely I forgot an important question.

Does anyone have experience with sourcing power adapters like the one
we need? If you have a proven provider for PSUs in Europe or Asia -
please let us know, this may save us quite some time and headache.

has 348 that are 12-18v output, 10-20w, and have connectors that are

I haven't realized that DigiKey, Avnet and others have PSU section, thanks!

PoE is an option, but UmTRX require too much power for the standard
PoE and we think that for lab usage PoE is an overkill.

Interesting. Do you know similar ones in Europe? We manufacture in
France and shipping enclosures from US doesn't look like a good idea.

Whats the total power budget? 802.3AF should be kosher with 13w at the
device, 802.3AT (PoE+) should be good up to a little over 20w

Im with you on the lab piece, Im just thinking of a seemingly
ubiquitous power source in a industrial environment -I bring this up
since so many industrial Wifi AP's (Gateworks, JJPlus, etc.) are PoE
powered

Not that Im aware of, I know of protocase since they did the backblaze
storage pods & you can order anything from them in individual piece
quantities -But thats not to say that there arent plenty of others
that offer the same services, I would imagine there would be a fair
amount of places in europe that will do sheet metal enclosures -If you
want something extruded though, they might have a MoQ to make the cost
of the die fabrication feasible...?

According to our latest measurements, UmTRX alone requires ~15W:
https://code.google.com/p/umtrx/wiki/UmTRXv2_Power

If you add UmSEL, it will add few Watts as well, but it should be
below 20W I think. So PoE+ may be an option for a UmTRX without an
external PA.

When we discussed internally, we discarded embedded PoE for a couple of reasons:
 1. We focused on medium-range cells which would need an external PA.
And in this case we're out of PoE power range. In case of a pico-cell
output power (50-200mW) we could do with PoE.
 2. We decided that for the first iteration we'd better focus on more
important issues and use an external PoE adapter if needed.
 3. PoE by default has 58VDC output. We replaced all capacitors to
tantalum ones and IIRC there was a concern that increasing input
voltage range to 48VDC may considerably add to the BOM cost. This is
according to my memories - I hope Andrey Sviyazov could correct me if
I'm wrong.

Taking all this into account, I think we might consider adding PoE
option in some later version, but it's not a focus for us now. If
someone wants to help us in adding this feature - please go ahead.
It's an open-source project after all.

With 15W-20W power consumption Andrey Sviyazov is worried that a sheet
metal enclosure might not be enough. I'm still inclined to give it a
try for a lab enclosure, though.

That said, we don't have manpower to do this right now. I estimate
this as at least a week of work and thus as I mentioned - if someone
is willing to make a design, we're ready to assist by all means.

1) POE components still very expensive for 1GBe and -40 deg C.
2) We'll experiment with POE when 100MB will possible to use.
Anyway, it should be some sppecial design like nanoBTS, for example.

We don't need -40C rating for them. PoE is useful for nano-BTS

I'm not sure I understand the question.

Well as Alexander pointed out, I think PoE makes more sense in short
range pico cell applications and I'm not sure the whole temp range is
such an issue for those applications.

Hi Alexander, Hi Andrey,

I am not sure we would need a specific design for PoE.
We could also keep our current design and provide a PoE splitter with a
plug adaptor.
This would let us keep our current design and make the UmTRX work with PoE.

Best regards.

Jean-Samuel.

Yes, be sure, I know why we need POE.
If we no more need outdoor then I agree.
And it will be separate design because we'll never get -40C as we need now.

Best regards,
Andrey Sviyazov.
P.S.
I mean why "Re: UmTRX Digest, Vol 4, Issue 35" ?

Hi Jean-Samuel.

You are absolutely right.
But I see that price in Russia market around $150.
And you should agree that it Is not such cheap as we wish.
So, using 100MB LAN per UmTRX board and internal PoE
for -40..+75C seem realistic to be implemented in future.
On other hand we can start to design openPoE project :)

Best regards,
Andrey Sviyazov.

Hi Thomas.

Do you use TXLPF and which if yes?
And also, please let us know other registers dump of TX part, especially
TXVGA's.
Btw, unfortunatelly, I do not know how to switch LPF otherwise than by
direct registers access.
Now I work with power consumption and forced to write to registers to see
can LPF to suppress spurs (which occur without LDO regulators) or not.

Best regards,
Andrey Sviyazov.

Yes, that's what we could do initially, it's not something we need
urgently. The discussion is whether we should consider this for some
later revision of UmTRX.

The concern about a separate PoE splitter is that it might reduce
overall system reliability. OTOH, it's easier to replace a broken
separate PoE splitter then replace the whole UmTRX if built-in PoE is
broken. AT the same time, separate PoE is more expensive and require
more space. Thus it's not clear to me whether a built-in PoE would be
a benefit or not.

Is there anything which prevents us from having it as an option on the
PCB? Then we would be able to decide whether we need it or not at
population time.

Darby is receiving e-mails from this mailing list in a digested
(batch) form. I.e. all e-mails from a given period of time come as a
single huge e-mail. And this huge e-mail has its subject like above.

Hi Srdjan,

Have you seen a question at the end of this e-mail, regarding the LMS
calibration?
To me it looks like a result of the I/Q imbalance which we should
compensate at the baseband level. Is that correct?

Hi Alexander,

It is IQ imbalance indeed. It has to be corrected in BB. I believe you 
have access to the document:

"LMS6002D Improving transceiver performance using digital techniques 
-1.0r1.pdf"

It may be useful. Also, we recommend to implement RX DC auto 
cancellation as explained in section 3.3 of the same document. This 
should solve RX LO leakage issue.

We usually measure < -60dBc unwanted image level when IQ imbalance is 
corrected.

Regards, Srdjan

Hi Srdjan,

If I understand correctly, I/Q imbalance calibration precision depends
on the sampling rate. What sampling rate do you use to achieve <-60dBc
image level?

I am not sure calibration precision is affected by sample rate. 
Theoretically, we are rotating I vector by alpha/2 and Q vector by 
-alpha/2 and that is done by multiplication. Hence, the resolution of 
quadrature phase error (alpha) which we can correct is defined by the 
with of multipliers.

Any way, we clocked ADCs at 15.36MHz (30.72MS/s digital IQ interface) in 
the experiment I mentioned.

Subject: UmTRX housing for labs usage.
Message-ID: <CAE9AREyBGieY2Eat6=iPa132A6LYzzjdWh2G-muCgDNPXD9vug@mail.gmail.com>

Hi all.

I spend this day in tries to find enclosure for UmTRX which are suggested
to use in labs.
I decided to return to my idea about fanless 5.25" tray form factor.
I think they must look good, low cost and popular.
It's all because mass production for competitive market.
Examples:
http://market.yandex.ru/model.xml?modelid=4957720&hid=818965
http://market.yandex.ru/model-spec.xml?modelid=2435964&hid=818965

http://www.amazon.de/Scythe-SCH-1000-Himuro-Festplattenk%C3%BChler/dp/B0017KAUHU

And one question:
Does anybody really uses USRP in closed enclosure?

Best regards,
Andrey Sviyazov.

Huh yes, I do ... 95% of the time it's closed in its box. I have all
the connectons I need routed to the outside and now with the WBX I
don't need to change daugtherboard very often ...

Hi Dmitri, Syvain.

Thaks for reply.

Sylvain, your 95% it is big reason for me to find enclosure.
Please help me too.

Dmitri, you are right, I thought about UmTRXv2 and future, of course.

Unfortunatelly, enclosure must be able to dissipate at least 15W
to keep it near on the table and feel comfortable.
So, only boxes with fan or fanless heat sink solutions can be used.

Best regards,
Andrey Sviyazov.

Alexander,


" UmTRXv2 samples for early adopters should be ready in just few weeks
" per here:
http://lists.osmocom.org/pipermail/umtrx/2012-October/000252.html

And this page states:

" Note: PCB layout will be published here when we start selling UmTRX
boards. Prior to that it's available per request to our partners. "

https://github.com/chemeris/umtrx-schematics

Does this mean people whom purchase the UmTRXv2 Samples will be able to
obtain the Schematics/Gerber Files ?


Sincerely,

Just curious - what do you need gerbers for? Want to make some improvements?

We encourage modifications, improvements and any other smart use of
UmTRX. I just wonder why do you need gerbers, while it's easier to
modify project files. The only downside is that you need Altium for
this.

Subject: UmTRXv2 Beta: Whats the maximum # of simultaneous callers
Message-ID: <CALJr4pXqAZXR79PfoBdZ7TDLHNpxsCiBFkhzDjybCaMbOCiohA@mail.gmail.com>

Hello,


I've read that the # of maximum callers is 15.


Since there are "Beta" version coming out will these be able to handle 15
simultaneous callers too?

A short answer is "yes, after a software update".

A longer answer is that hardware supports dual-TRX operation, but
software support is not there yet. We might be able to fix software
before we ship beta units, but even if not - you will be able to get
the software update later.
Also keep in mind, that UmTRX should be able to run multi-ARFCN
OpenBTS and in this case it'll be able to handle much more calls. We
haven't tested this mode of operation extensively yet, but
theoretically we might be able to support 14ARFCNs (2x7ARFCN) which
equals to (14*8-1)=111 calls. At this scale you're most likely limited
by computing power of your PC rather then UmTRX hardware. Whether we
could get UmTRX in Multi-ARFCN mode through certification or not is
still a question, but it should be fine for lab testing.

Alexander,


Superb potential of the device you and the Fairwaves team are bringing to
fruition.

I also look forward to your future potential product, UmTRXv3 4G/LTE.

I know its just something your team and you have thought about publically,
alot of us would love to see such.

Thank you for your responses.

Forgot to mention, < -60dBc image suppression has been achieved by 
correcting both phase and gain imbalance.

Subject: LNA and Noise Figure improvement


Hi Andrey,

I understand you plan to prepare the UmTRXv3.

I would need to discuss about the Rx Noise Figure improvement.
With UmSEL, according to your calculations, NF would be around 0.7 dB
(excluding duplexer IL) with the MGA-13116.
It would be interesting to try to improve this figure with a very
first stage LNA based on the MGA-633P8. This would let us reach a NF
as low as about 0.4 dB.

Adding this very first stage LNA in the Rx path brings a few questions.

1/ To improve isolation with the other RF parts, would we need to have
this LNA in a separate shielded enclosure ?
If yes, we would need a 5V power supply for this LNA. To have a better
shielding between the voltage regulator circuitery and the LNA, it
should be nice to have the 5V voltage regulator outside of the LNA
enclosure. To make this possible, it would be very useful to add a 5V
voltage regulator and connector on the UmTRXv3.
If not, we do not need specific modifications on the UmTRXv3 but we
would need to add an MGA-633P8/634P8 as a very first stage in the
UmSEL.

2/ Whatever external or on the UmSEL, this extra LNA will increase the
total gain. Considering your calculation, the UmSEL IIP3 is already as
low as around 1 dBm. If we add a very first stage LNA, this IIP3 will
go down to about -15 dBm. This could be a problem for inband blockers.
Even if, in real life situation in the field, I am not sure it will be
a very big problem, it will be a problem to pass the spec.
Would you have another idea to improve the NF ?
If not, could you please let me know what NF we could expect with the
current design (UmSEL with MGA-13116/13216) in both 900 and 1800 bands
?

Best regards.

Jean-Samuel.

HI Jean-Samuel.

Not really sure to do UmTRXv3 right now.
On my opinion now we should found as much issues as possible with v2.
For example, now I am working with power consumptions.

I have to think a bit about NF improvement you suggest.
I'll let you know my calculations by tommorow.

Best regards,
Andrey Sviyazov.

I recently posted about multicarrier operation with UmTRX.

http://lists.osmocom.org/pipermail/umtrx/2012-October/000250.html

More extensive testing remains, but 15 calls in a lab environment does
not pose any significant issues. Larger scale operation - with power
amplifier and /or 50+ simultaneous users - remains to be tested.

I set LPF through the UHD interface. This was necessary because the
default setting was too narrow. Unfortunately, I did not capture at
any register values.

  https://github.com/ttsou/openbts-multi-arfcn/commit/a95d8f7f

I don't see how the LPF can suppress these spurs because they occur
inside the multicarrier passband.

Hi Thomas,

Could you please describe symptoms which you observe on your UmTRX? We
have to figure out the reason for the improper behavior and if this is
a manufacturing issue - make sure this won't happen for the next
batch.

Hi Alexander,

Thank you very much for your reply and detailled explainations.
Now I understand.

My point of view is we do not really care of a few watts power consumption
saving for the lab version. At worst, we can still add a fan in the lab
enclosure, as for the USRP which also dissipate up to about 15 Watts.
On the other side, it makes a lot of sense to save some power consumption
for the industrial version as, on the field, every watt counts and we also
need to dissipate the heat without fan for better reliability.

Considering this, I believe as follow.
Either we are able to decrease the power consumption and keep good enough
performances for industrial applications. In this case, we should make this
modification for both lab and industrial versions.
Either decreasing the power consumption will decrease the performances. In
this case, I do not think this worth making this modification at all.
In both cases, I would suggest we keep the same design for both lab and
industrial versions, either with or without the modification.

Moreover, if both lab and industrial versions are the same, except
connectors may be, debug from lab users may help industrial users and debug
from industrial users may help lab users. This would be really easier to
get a reliable single board for both lab and industrial applications.

Best regards.

Jean-Samuel.
:-)

Hi Andrey,

Do you think it will be possible to decrease the power consumption and to
keep the best possible performances for industrial applications ?
I know you cannot be sure about this but I would like to know how confident
you feel about this ?

I was going to retest, I can't do that until later tonight.

Anyhow, I ran into some Ethernet issues when I first booted the
UmTRXv2 last week. Board powers up and FPGA loads fine from JTAG with
recent .bit image, but I was not able to get network connectivity. I
noted the following observations only when Ethernet cable is plugged
in. After brief discussions with Alexander, it seems that this
behavior is not expected.

LED 'I' is on constantly but blinks every few seconds
'LED4' blinks every few seconds
Voltage at 1.2V regulator drops to .8V when blinking occurs

Also, the above behavior is sometimes present before the FPGA load if
Ethernet is connected.

I use the following power supply at 12V; current is not limited.

That's all I have right now from some earlier notes. Any thoughts?

at 20w of power consumption, this comes to roughly 68btu of generated
heat -Is there a reason convection cooling in a sheetmetal enclosure
wouldent work for this board?

No reason except the fact I don't like noisy fans. :)

Seriously speaking - it's just easier to find a case without a fan
from what I see. But if someone find or design a good case with a fan
- we'll use it.

Hi Jean-Samuel.

About power consumption and performancea I can say that spurs at 500 kHz
offset around 6dB above TX LO noise plot.
It wad measured when 3.3V come from dogs through TI2012U601.
Tomorrow I'll measure all again and share pics in this topic.
As I mentioned, I'll try to find better filter to suppress 500kHz.
Please let me know any partnumbers or suppliers you known.
Also unoccupied place under 3.3V LDO's near LMS seems a good place for
thermal sensors.
About rf connectors, now I am sure that MCX much better then U_FL and we
should return them.
To connect UmSEL to UmTRX v2.1 required U_FL-MCX cable assemblies till new
UmSEL version.
Also possible to use direct cable soldering to UmSEL board.
Of course, last variant look not perfect.
About requirements at 400kHz we can't meet, I actually can't understand
what do you mean.

Best regards,
Andrey Sviyazov.

No reason except the fact I don't like noisy fans. :)

Seriously speaking - it's just easier to find a case without a fan
from what I see. But if someone find or design a good case with a fan
- we'll use it.

lol   I hear ya, Im just thinking with that seemingly minimal amount
of heat (that many BTU's this would raise the temp of a us gal of
water by 8.2f, or a liter of water by ~17c), it shouldent really make
too much of a difference to have a rectangular case thats enclosed &
has a few holes punched in it...

To my knowledge, theres no special cooling considerations taken into
account for any of the USRP's?

Hi

I'm preparing to implement a legacy GSM roaming for OpenBTS network. 

To start with, I'm trying to get a minimal list of mandatory MAP services to allow foreign subscribers to roam inside OpenBTS.
CAMEL is not discussed now.

Your help is appreciated.?

Dmitri
