Frequency Bands
The named radio-frequency ranges (such as L, S, C, X, Ku, and Ka band) used for different satellite services, each with distinct propagation and capacity trade-offs.
Satellite communications use conventionally named frequency bands — for example L and S band for mobile and telemetry, C band for resilient links, X band for government use, and Ku and Ka band for high-throughput broadband.
Higher bands offer more bandwidth but suffer greater rain attenuation. Band choice is constrained by ITU allocations, coordination, and national licences, making spectrum a strategic and regulated resource.
