Hi ftth, >>My next question is how you'd go about mandating this reporting capability into every new mobile device, and how many years before old devices have all been "upgraded" to devices with the reporting.<< The rules for using spectrum already describe frequency coordination, and adding other Cognitive Radio conditions for sharing probably takes eight years (two WRCs) per band under 2 GHz. The online coordination capability is to share bands with prior allocations, but as we've seen in PLMRS, the prior allocations may fade into insignificance. Bands above 5 GHz will take ~4 years once there is some success in a sub-gigaHertz band. I think Personal mobile 2-way radios get replaced more frequently than one people generation - twenty years. >> "Why would any radio signatures be necessary if the protected radios do not move?" Doesn't that question assume a fixed device cannot change its transmit parameters (power, channel, even air interface technology for a multi-mode, multi-band fixed device)?<< No, it assumes the geo-database is informed of the radio characteristics of the fixed devices - Class D transmitters change their transmit power on a daily cycle fcc.gov Broadcast services will have receiver protection built into the geo-location database calculations (ref. clear channels).
