UK Spectrum Allocation [Return to main Technology page] Frequency assignment is the authorisation to use a frequency channel under specified condition. The conditions will include location, power level, modulation and bandwidth. The assignment by central body such as the RA allows close co-ordination, permitting reasonable frequency re-use across the UK.
