Fairwaves is proud to announce that Open Source Edition of UmSITE-TM3 — a rugged 2x3W GSM base station, designed for rural and remote regions and extreme climate conditions — is now available to order.

UmSITE-TM3 is based on the same flexible architecture as UmDESK, built with industrial-grade components and rugged packaging. 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 UmTRX SDR transceiver, UmSITE-TM3 OSE is the perfect platform for Osmocom and OpenBTS GSM applications.

UmSITE-TM3 OSE Key features

• rugged IP65/IP67 design that can operate in ambient temperatures of up to +55C with direct sunlight;
• all-in-one solution which integrates dual-channel transceiver, single board computer (SBC), amplifiers, duplexers and all required RF components;
• 6W total RF output power (3W per channel);
• pre-installed Osmocom software stack that can be configured to operate in Network-in-The-Box (NITB) and pure BTS/BSC modes;
• compatible with the OpenBTS software stack.

Mobile World Congress demo

If you're attending MWC in Barcelona this week, we invite you to come to see UmSITE-TM3 as part of a live demo of a completely open-source mobile network at the Canonical/Ubuntu booth at Hall 8.1 at App Planet Stand CC8.20.

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".

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, Lime Microsystems for open-source friendly SDR chips and to everyone else for their support!
