Editing Frequency-hopping spread spectrum (section)

=== Military ===
[[Spread spectrum|Spread-spectrum]] signals are highly resistant to deliberate [[radio jamming|jamming]] unless the adversary has knowledge of the frequency-hopping pattern. Military radios generate the frequency-hopping pattern under the control of a secret [[TRANSEC|Transmission Security Key]] (TRANSEC) that the sender and receiver share in advance. This key is generated by devices such as the KY-57 Speech Security Equipment. United States military radios that use frequency hopping include the JTIDS/MIDS family, the [[HAVE QUICK]] Aeronautical Mobile communications system, and the [[SINCGARS]] Combat Net Radio, [[Link-16]].
