Sorry missed the zero, 250 MHz. So you would have a lot of channels. Get those JRC radios certified under the current PTP rules (these are TDMA radios, should be an easy argument) and we have a lot of spectrum and equipment ready ALMOST TODAY to deploy high capacity PTMP systems.... no waiting for new spectrum allocations, very interesting. Anyone know who those companies used to make their case at the FCC for certification? Might be worth hiring them to get the JRC Radios through the process.
