UmTRX

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. See UmTRX....

Miscellaneous Projects

This is basically a place-holder for everything else that doesn't fit in other places.
