1) nanoBTS based The nanoBTS are 200mW only, so we would need a booster. Those cost about 1000 EUR for 6W downlink power + 18dB uplink LNA. Who is going to fund that? Also, we would need a combiner/splitter to run something like a 3-TRX setup.
i could get 3 amplifiers by R&S from a friend. each one has 20 watts output power max. here is a similar device: http://www.radiosurplus.it/pdf/TSAMPG.pdf

thanks a lot. The problem is that the TX PA alone isn't of much use if we don't have a duplexer/circulater, as well as uplink LNA that goes with it. -- - Harald Welte <laforge@gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
