Editing Frequency-hopping spread spectrum (section)

=== Civilian ===
In the US, since the [[Federal Communications Commission]] (FCC) amended rules to allow FHSS systems in the unregulated 2.4&nbsp;GHz band, many consumer devices in that band have employed various FHSS modes. eFCC CFR 47 part 15.247 covers the regulations in the US for  902–928&nbsp;MHz, 2400–2483.5&nbsp;MHz, and 5725–5850&nbsp;MHz bands, and the requirements for frequency hopping.<ref>{{cite web |title=47 CFR § 15.247 - Operation within the bands 902–928 MHz, 2400–2483.5 MHz, and 5725–5850 MHz. |url=https://www.law.cornell.edu/cfr/text/47/15.247 |website=LII / Legal Information Institute |publisher=law.cornell.edu |access-date=17 December 2019 |language=en}}</ref>

Some [[walkie-talkies]] that employ FHSS technology have been developed for unlicensed use on the 900&nbsp;MHz band. FHSS technology is also used in many hobby transmitters and receivers used for [[radio-controlled model]] cars, airplanes, and drones. A type of multiple access is achieved allowing hundreds of transmitter/receiver pairs to be operated simultaneously on the same band, in contrast to previous FM or AM radio-controlled systems that had limited simultaneous channels.
