and circuitry to reduce radio frequency (RF) gain. UHF radios differ in terms of range, which is usually measured in miles or kilometers. Some FRS radios and GMRS radios use AA or AAA batteries.

Abstract: The literature on systems design for the transmission of high speed digital data in the "megabits per second" range over UHF links is scarce and somewhat contradictory. Essentially, the ...
