Alexander Chemeris alexander.chemeris at gmail.comHi 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! -- Regards, Alexander Chemeris.
