frequency reuse

noun

1. A technique that allows the same frequency band to be used multiple times within a single satellite system by separating signals through spatial isolation (spot beams), polarization, or both.
2. Frequency reuse is the primary mechanism by which modern high-throughput satellites achieve aggregate capacities of hundreds of gigabits per second using limited spectrum allocations. A satellite with 100 spot beams can reuse each frequency assignment dozens of times.
