[5] The ultra-high frequency (UHF) radio infrastructure (225 MHz - 400 MHz) is used by most air navigation service providers (ANSPs) as a fundamental alternative to ensure ATC communications with non-8.33 kHz equipped State aircraft operating GAT/IFR and, in some cases to support OAT flights. One of its roles is to allocate all radio bandwidths and frequencies. CAP was one of the groups interested in the adoption of the "military FRS" UHF short-range service (14 channel UHF intra squad radio or ISR) as well.
