Hi All, I spotted some interesting 10 GHz commercial Point-to-Point equipment that might work on our 3cm ham band. http://www.mimosa.co/products/b11 The radio spec say is physically supports 10.0-11.7 but the FCC version available in the US is locked to 10.7-11.7 GHz. The radio is TDMA-FD so presumably no diplexers or band filters like classic duplex uWave gear to get in the way of operating lower in the band. The company is in Santa Clara..it might be possible to convince them to support a version that works on our 3cm ham band, 10.0-10.5 GHz. Countries in ITU Region 1 and 3 allocate 10.0-10.45 to Fixed service, so this may be as easy as buying the version with International software. It's a bit pricey, but could be good for backbone links, leaving 5 GHz for access nodes. As I was researching this, I realized that Mimosa was the company that petitioned the FCC to reallocate the 10GHz ham band. Using their equipment on our 3cm band, and then showing how we're actually using the 3cm band might be fun! :-) Radio MIMO & Modulation 4x4:4 MIMO OFDM up to 256QAM Bandwidth Single or Dual 20/40/80 MHz channels Frequency Range 10000-11700 MHz restricted by country of operation Max Output Power 24 dBm Sensitivity ( MCS 0 ) -87 dBm @ 80 MHz -90 dBm @ 40 MHz -93 dBm @ 20 MHz I do microwave contesting on 10 GHz. It's a great band. Regards, Randy W3RWN / VE3RWN randy@neals.ca Seattle, WA
