FHSS
What should I say here about frequency hopping spread spectrum (FHSS)?
... say a few words about adaptive frequency-hopping spread spectrum (AFH)...
Is it true that adaptive FHSS can give higher bandwidth and use less power (longer battery life) than any fixed-frequency broadcast system?
... mention systems that combine FHSS with mesh networking ...
- Other places we talk about FHSS on Open Circuits.
legal considerations
In addition to the physical limitations mentioned above, there are also legal considerations, such as, for example:
(h) The incorporation of intelligence within a frequency hopping spread spectrum system that permits the system to recognize other users within the spectrum band so that it individually and independently chooses and adapts its hopsets to avoid hopping on occupied channels is permitted. The coordination of frequency hopping systems in any other manner for the express purpose of avoiding the simultaneous occupancy of individual hopping frequencies by multiple transmitters is not permitted. --47CFR15.247 : FCC Part 15 Section 15.247
