I recently saw this video / post in which Osmocom had be used to create a GSM Base Station
with a LimeSDR mini and a Raspberry PI.
https://www.crowdsupply.com/lime-micro/limesdr-mini/updates/gsm-base-statio…
I was very interested in this, because I need to be able to test cellular broadcast
messages, and this seemed to provide a way to do this.. CB seems to be supported in
Osmocom.
I am a bit overwhelmed about what I need to install, to get a minimal, but functioning
‘system’ running, so I can test some features.. I ordered a LimeSDR and it hopefully will
arrive sometime after the new year
But I wanted to get a jump start on it now. Is there some instructions in the wiki,
I just did’tn know which ones to follow.
Kind Regards

Hi,
For the specific parts when using a LimeSDR, you can check the wiki page
which is already mentioned in the link you shared [1].
You will basically need to install LimeSuite, SopadySDR, SoapyUHD and
libuhd, as explained in the same wiki page (there's a step by step
section to compile everything yourself). I personally installed most of
the dependencies required from both normal and AUR repositories since
I'm using Archlinux, so not sure if there's an apt repository for debian
systems.
For the generic parts you need to run the GSM network, you can easily
install them using the osmocom apt repositories [2].
I think you can also find the "limesuite" package available in the
osmocom repositories btw.
After my initial tests, it mostly works but I found some issues, which I
started to work on. For instance, lots of times when I start osmo-trx or
osmo-bts-trx, one of the two fails due to some timeout [3]. We also
found out that the RX antenna is by default connected to the
LowFrequency RX input which may not be suitable for arfcns in band
DCS1800, which we were using at the moment, and we had to plug the
antenna to the WideFrequency one.

In the video that I mentioned above, there was mention that sysmocom where making an ‘all
in one’ package that could be used via some kind of web app store..
Was that something that’s happened, or is going to happen.. It seems I might be able to
build this all from packages however.

Hi Andrew,
[speaking with both my Osmocom and sysmocom hats here]

Indeed, this was and still is the plan. It would be simiar to the sysmoBTS based
starter kits which sysmocom is selling for the past 5 years or so. The difference
would be that it's LimeSDR based, not sysmoBTS based.
The revenue from those starter kits is a significant source of funding for sysmocom
to pay an entire team of developers doing nothing else but workgin on the various
cellular
related Osmocom projects - from bug fixing to new features to documentation to general
maintenance tasks.

However, we unfortunately still haven't been able to get around to build that
'snap'
package for LimeSDR, sorry for that. It still is on our agenda.

This is correct. In Osmocom (and at sysmocom) we are 100% open source. We work
upstream,
and we don't do "open core" models where you only get a feature crippled
version of the
software. What symocom ships is mainline Osmocom. So for sure, you can set up the
entire Osmocom cellular stack yourself.
Regards,
Harald

I did’tn appreciate that there was a starter kit! I’m not particaully stuck with a
limeSDR, it was just I saw the video and thought, great that might solve my problem
Can you point me to the starter kit, and give me an idea about what they cost. I’ve
ordered a LimeSDR mini, but I’m sure it will come in handy for something else.
However, we unfortunately still haven't been able
to get around to build that 'snap'
package for LimeSDR, sorry for that. It still is on

When its done, that will be awesome.
So for sure, you can set up the

I might just have to do this, but I’ll probably end up asking a thousand questions. In
return I’ll provide a easy to follow build for the next guy who follows me!

If you register at the osmocom.org redmine, tell us your login name and we'll
grant you wiki editing rights, so that you can compose / fix how-to guides. If
you can find the time, that would certainly be appreciated :)
