Help with RF signals and types.
Help with RF signals and types.
(OP)
Hi,
I need help with the different types of signals and the ranges that they fall in, most specifically RF, GSM, firewire and high frequency communications. I am looking for a good link to any site giving good details on frequency ranges.

RE: Help with RF signals and types.
HF is usually defined as RF between 3 and 30 MHz (also known as 'shortwave').
Not sure off-hand about GSM - it's one of those cell phone standards.

Whereabouts in the world are you, Salmonaxe, since spectrum plans are defined by national governments and vary throughout the world.
Generally:
HF - 3-30MHz
VHF - 30-300MHz
UHF - 300MHz-3GHz
SHF - 3-30GHz (also called millimetre wave)
EHF - 30-300GHz
