Hi Neels, Sure :) I looked into other 2G/3G projects, mainly OpenBTS and YateBTS and saw that OpenBTS-UMTS should support 3G with my SDR. But I'd very much prefer sticking to Osmocom, because OpenBTS seems not very active, at least towards the public. So I was wondering if someone might be working on another Osmocom project that I have not come across yet, that might provide an alternative to buying a nano3G. Actually, I just found [1], which also uses the nano3G. So nano3G seems like the way to go right now.

Hi Neels, Can we buy the nano3G only from sysmocom and get it working with limesdr for transceiver?  I still wondering how it works together wirh sdr, is that possible?

It is also not trivial to write a separate RNC that would allow operating Iu proper instead of requiring Iuh, which would open up more possibilities for 3G base station hardware. None of GSM is trivial, but we have no RNC yet :) At Osmocom/sysmocom, we have the sysmoCell 5k series, and have also managed to get the far cheaper nano3G plugged to our osmo-hnbgw; plus at sysmocom we have a certain number of them available. So wherever you look in the Osmocom ecosystem, you will see the nano3G popping up its head. The Accelerate3g5 was specifically launched by sysmocom to get more people involved in Osmocom 3G and, naturally, we gave away nano3G units to about a dozen projects. http://osmocom.org/projects/cellular-infrastructure/wiki/Accelerate3g5 There is an ongoing process of finding more suitable femto cells, and it looks promising, though it's not worth an announcement as of yet. Anyone out there may join the effort and investigate femto cell models available on the market and find ways to unlock them so they become generally usable with Osmocom 3G. If you want to get started, the nano3G indeed is your best bet with Osmocom at the moment. Be aware that not all nano3G you can buy out there are ready to be configured and talk Iuh to any host, so sysmocom is probably the safest source. ~N

Consider: these answers are for free to you, but they cost us time and actually real money. We'll do it any time for *useful* requests. Thanks! I mean, you've been camping the community for long enough to know where all the information can be found. The sysmoBTS is a complete 2G base station, piece of hardware. It has an ethernet plug to feed Abis/GPRS-NS and you get a 2G cell on the air "at the other end". The nano3G is a complete 3G base station, piece of hardware, aka hNodeB aka femto cell. It has an ethernet plug to feed Iuh and you get a 3G cell on the air "at the other end". These two are completely separate and utterly unrelated, and they cannot be plugged into each other in a useful way, besides operating them with a core network that is able to serve both technologies at the same time.
