The use of wireless radio connections is increasing. Operation in the license free bands should conform to FCC 15.247 regulations. "Frequency hopping" is an important part of these regulations. A system using "frequency hopping" will benefit from reduced multi-path fading, increased output power and reduced system-to-system interference. This document describes several aspects of the frequency hopping in the 915 MHz band with emphasis on typical WPAN (Wireless Personal Area Network) properties. Micrel's MICRF505 IC solution is ideally suited for this type of operation.
