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.
• 5 GHz: This range divides into several sections called Unlicensed National Information Infrastructure

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.
