Hi all,
the history of OpenBSC (and thus the Osmocom umbrella project) started with the Siemens BS-11 microBTS.
I still have three of those BTS, and think that one is enough, i.e. two BS-11 are available.
If you are an active contributor to OpenBSC or represent a public research organization, I will provide them free of charge, you only have to pay for shipping.
For all other interested parties, I would like 200 EUR per unit (excl. shipping), which still makes it one of the cheapest options for running your own network with OpenBSC.
If you're not familiar with the BS-11 and its technical data, please check http://openbsc.osmocom.org/trac/wiki/BS11 and related pages i nthe wiki.
They units I have available are with 230V power supply and operate in the GSM900 band.
I also have one compatible HFC-E1 PCI E1 adapter (supported by mISDN + OpenBSC) available.
Please contact me privately if you are interested.
Regards, Harald
