The first low-cost rugged GSM/SDR base station designed for Osmocom and OpenBTS
We are proud to announce that UmSITE-TM3 — a rugged 2x3W GSM base station, designed for rural and remote regions and extreme climate conditions — Open Source Edition is now available to order.
UmSITE-TM3 is based on the same highly flexible architecture as UmDESK, built with industrial-grade components and packaged in a rugged enclosure. Two independent TRX channels, each with 3W TX power (6W total), make it ideal for outdoor installations covering areas of up to 5 km.
Thanks to the modular open source software that comes pre-installed, this base station can be used for all manner of experiments and test installations. Built upon the proven UmTRX SDR transceiver, UmSITE-TM3 OSE is the perfect platform for Osmocom and OpenBTS GSM applications.
We would like to take this opportunity to give our thanks to Rhizomatica for their early feedback, BJT Partners for their role in its development and to everyone else for their support!

FAQ
Is there a commercial version?
We are currently developing a commercial version of the UmSITE-TM3, which will be integrated with the Fairwaves core network, for use by companies who would like to use them to operate commercial GSM networks. Stay tuned for more details!
Will it work with UMTS/LTE?
While the UmTRX SDR transceiver hardware is perfectly capable of handling UMTS and LTE waveforms, the SBC used by the UmSITE-TM3 has an Intel Atom processor, which doesn’t have quite enough processing power to handle UMTS or LTE. So, unfortunately the answer is “no”.
