11.10.11 Why Doesn'T Every Communication System Simply Use The Highest Frequency Available?
Higher frequencies offer greater bandwidth, but they also introduce new engineering challenges. This FAQ examines the trade-offs between bandwidth, antenna size, propagation range, atmospheric attenuation, equipment complexity, and spectrum availability to explain why communication systems operate across such a wide range of frequencies.
