FCC Spectrum Allocation of 800 MHz Band * - 1974 * - Allocation for US zone (distinctive in Mexican and Canadian outskirt districts) Up-Link 808.5 816 821 825 806 100 Conventional Channels (authorized one channel at once). Accessible to business, inner, or open wellbeing frameworks. 200 Trunked Channels (authorized in 5, 10, 15, & 20 channel non-touching obstructs, various channels at once). Accessible to business, inner, or open wellbeing frameworks. Transmission Ch. 60-69 800 MHz Interleaved Band (counting Bus/ILT/PS/SMR) 300 Channels FCC Reserved For Future Use Cellular Band FCC Reserved For Future Use 851 853.5 861 866 870 Down-Link 1974 - FCC\'s underlying distribution of land portable radio administrations at 800 MHz and beginning cell assignments. Arrive versatile allotments were innovation based, not benefit based. A straightforward 70-mile co-channel partition manage received to avoid obstruction. Candidates pick amongst traditional and trunked channels on a "first-come, initially served" premise.

EA Auction champs approved over-layed 25 channel coterminous pieces (SMR as it were). Interleaved Area (counting Middle 80 SMR) SMR, Bus/ILT and Public Safety occupants work routine and trunked frameworks. SMR use on Bus/ILT range is around half of Business channels and 67% of ILT channels. EA Auction victors approved on 16 five-channel non-touching pieces (SMR as it were).
