Short for radio frequency, any frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. Many wireless technologies are based on RF field propagation.
These frequencies make up part of the electromagnetic radiation spectrum:
Ultra-low frequency (ULF) -- 0-3 Hz
Extremely low frequency (ELF) -- 3 Hz - 3 kHz
Very low frequency (VLF) -- 3kHz - 30 kHz
Low frequency (LF) -- 30 kHz - 300 kHz
Medium frequency (MF) -- 300 kHz - 3 MHz
High frequency (HF) -- 3MHz - 30 MHz
Very high frequency (VHF) -- 30 MHz - 300 MHz
Ultra-high frequency (UHF)-- 300MHz - 3 GHz
Super high frequency (SHF) -- 3GHz - 30 GHz
Extremely high frequency (EHF) -- 30GHz - 300 GHz
Radio frequency is also abbreviated as rf or r.f..
Minimizing 802.11 Interference Issues RF interference will continue to plague current and future 802.11b
implementations unless an adequate site survey is conducted - preferably
prior to actual network installation.
Tools Simplify 802.11 Deployments Wireless LAN installation is tricky. The construction of a facility and silent sources of RF interference impact the propagation of radio waves, often in odd ways.
