标准简介：As part of its work on Agenda item 1.6 of the 2007 World Radiocommunication Conference (WRC-07), ITU-R considered allocations to the aeronautical mobile (R) service (AM(R)S) in some portions of the 960-1 164 MHz and 5 000-5 150 MHz bands. Based on available studies, two distinct types of aeronautical applications require AM(R)S spectrum. The first, like the current VHF AM(R)S, requires longer propagation distances (e.g. out to radio line-of-sight), moderate bandwidth, and a number of distinctchannels to allow for sector-to-sector assignments.
