_Between Christmas and Chinese New Year the price of UmTRX v2.2 is  
dropped  
from $1500 to $850._

Offer duration: Dec 24, 2014 – Feb 19, 2015

Availability for shipment: 40 pcs starting January, 2015

We hugely appreciate all the effort that goes into making open source  
telecoms a reality, and in recognition of this we want to do all we can  
to  
support the community and to enable more to work in this exciting area  
and,  
hopefully one day, become contributors.

With this in mind we are pleased to announce that for a limited time we  
have significantly dropped the price of our dual-channel, wideband — and  
open hardware! — SDR transceiver, UmTRX [http://umtrx.org/](http://umtrx.org/). As a  
special  
for developers we are making the recently updated v2.2 hardware  
[http://umtrx.org/umtrx-hardware-updates/](http://umtrx.org/umtrx-hardware-updates/) available at the more  
affordable  
price of $850, instead of the regular pricing of $1,500. This comes  
supplied complete with a power supply and coax pigtails.

If you place an order

now  
it will be received in January!

_This offer is limited to a maximum of 2 lab kits per individual and 10  
per  
university._

_What is UmTRX?_

For those not familiar with UmTRX, it is a dual-channel wide-band SDR  
platform with gigabit Ethernet connectivity, developed by Fairwaves and  
designed to be used as a transceiver (TRX) with OpenBTS  
[http://openbts.org/](http://openbts.org/) and Osmocom  
[http://umtrx.org/applications/osmocom/](http://umtrx.org/applications/osmocom/) GSM  
base stations.

Given its SDR architecture, UmTRX can easily be used with many other RF  
applications. Combining FPGA and FPRF (Field-Programmable RF)  
technology,  
it has the ability to process data on a CPU or a DSP, which makes it an  
extraordinarily flexible platform.

_Why UmTRX?_

In our opinion there are a number of particularly interesting solutions  
for  
use with OpenBTS and Osmocom.

Nuand [http://nuand.com/](http://nuand.com/)‘s BladeRF is an affordable solution for  
hackers  
who want configure it all by themselves. Host connection is via USB 3.0  
and  
use is supported with Linux, Windows and Mac OS X. It has a single  
transceiver channel.

The Ettus R. [http://www.ettus.com/](http://www.ettus.com/) devices provide a flexible  
solution that is well suited to universities. Their USRP™ platform  
supports  
RF applications from DC to 6 GHz, there are a wide range of devices and  
options, with a product line that spans from affordable hobbyist SDRs to  
high-end high-bandwidth radios.

Fairwaves [http://fairwaves.co/](http://fairwaves.co/) UmTRX has been developed with GSM  
specifically in mind and provides two transceiver channels, host  
connection  
is via gigabit Ethernet and it is well suited to use in industrial  
applications. It includes a TCXO and GPS for frequency stability, and  
while  
it is designed to be built into mobile base stations, it can also easily  
be  
used with many other applications. Furthermore, an alternate firmware,  
4xDDC  
[http://umtrx.org/hardware/4xddc/](http://umtrx.org/hardware/4xddc/), can be loaded to provide double the  
number of receive signal paths (4) for receive-only applications.  
Expansion  
is possible via mezzanine cards and the UmSEL  
[http://umtrx.org/hardware/umsel/](http://umtrx.org/hardware/umsel/) daughter board can be used for  
improved  
GSM performance.

So, if you need an affordable dual-channel solution for GSM — with  
GPS-locked frequency stability — UmTRX is a great choice
