Spectrum Allocation

Spectrum allocation is the process by which radio frequency bands are designated for specific uses — satellite communications (FSS, MSS, BSS), navigation (RNSS), Earth observation, space research, and others. The ITU's Radio Regulations divide the spectrum into allocations by service type and by geographic region. Individual satellites must then be coordinated within their allocated bands to avoid interfering with other systems. The explosive growth of mega-constellations (Starlink, OneWeb, Amazon Leo) has created intense demand for Ka-band and V-band spectrum. World Radiocommunication Conferences (WRC), held every 3–4 years, update allocations — WRC-23 addressed new satellite broadband allocations.
