Reasons for DFS requirement in Europe

  • Equipment shall employ a DFS mechanism to detect interference from other systems and therefore is able to avoid co-channel operation with other systems, notably radar systems

  • DFS wil also be required to provide a spread of the loading across a minimum of 14 channels to further facilitate sharing with satellite services

The only implied technical requirement is that

DFS Must be able to detect Radars and

change channel accordingly

Satellite sharing is fasilitated as a ”side effect”
