Radio Frequency Ranges
WLAN communications use the following radio frequency (RF) ranges:
•
2.4 GHz: Many devices that use 2.4 GHz can potentially interfere with the 802.11b/g connection.
Interference can produce a Denial of Service (DoS) scenario, possibly preventing successful 802.11
transmissions.
•
5 GHz: This range divides into several sections called Unlicensed National Information Infrastructure
(UNII) bands, each of which has four channels. The channels are spaced at 20 MHz to provide
nonoverlapping channels and more channels than 2.4 GHz provides.
802.11 Data Rates, Transmit Power, Ranges, and Decibel Tolerances
The following table lists the transmit (Tx) power capacities, data rates, ranges in feet and meters, and decibels
that the receiver tolerates for the 801.11 standards.
