Hi all, (and sorry to those who receive this twice)
At Sept 15th I will speak at the Open Hardware Summit at the breakout session "Open Hardware in Voice Telecommunications" and there I will present Fairwaves project to create an open hardware transceiver for OpenBTS. Someone may recall I proposed similar project about 1.5 years ago, but then abandoned due to lack of interest from the community. Now it was revived on a new level, thanks to financial and motivational support from Jean-Samuel Najnudel of BJT Partners SARL. As an experiment this project will be completely open-sourced in an open-source hardware way.
Project is in active development, so just to give you an idea of what we're aiming: * Targeted for rural installations. * CAPEX and OPEX optimized. * 2 TRX per sector. Each TRX connected to its own antenna with its own saturated (=cheap) power amplifier on Tx side. On Rx side both antennas are used to provide diversity receive. * Reference clock synchronized to GPS for accurate timing. * Based on USRP N200, but with Xilinx Spartan 6 and LimeMicro LMS6002D. Which means it's actually design is much more capable then just GSM.
More details, web-site, schematics, etc will be available after OHS. First samples of the hardware we hope to have at the end of this year.
If you're going to OHS - come to our breakout session to discuss the project and share your ideas!
This is awesome Alexander. Please keep the list (and me personally) informed, I'd love to help in whatever context I can.

Kurtis,
I will. And thank you for your interest.

Hi,
What is the Tx power being aimed for 1W & 5W or more ?

Standard output power of the transceiver will be 3mW, which is a common output power for GSM transceivers. You could connect an external GSM PA to get any power you need. We may provide an option for integrated 1-3W power amplifier, but we haven't decided yet.
Note, that if you install a PA for Tx, you should also install appropriate LNA for Rx and duplexer to separate them.
