UmTRX v2.1 simple scheme

UmTRX is a dual-channel wide-band SDR transceiver that is designed to be used with OpenBTS and OsmoBTS GSM base stations. Given its SDR architecture UmTRX can easily be used with many other RF applications, and a combination of FPGA and FPRF (Field-Programmable RF) technology plus the ability to process data on a CPU or a DSP, makes it an extraordinarily flexible platform.

UmTRX is connected to a host via gigabit Ethernet. The Fairwaves version of UHD provides FPGA HDL and firmware, along with a host driver.

Laboratory packages and turnkey solutions are available from Fairwaves.
