Abstract
The author proposes that subscriber radio should be operated in coexistence with high capacity long haul-digital microwave system in 4-6 GHz bands, where it is easy to obtain systems immune to rainfall attenuation and with relatively high system gain. The required modifications for the existing long haul system are to strengthen the transmitter out-of-band emission suppression and to adopt cochannel radio-frequency allocation. Coexistence with local distribution radio can be allowed in the vacant band gaps between adjacent channels in the cochannel scheme
