The frequency hopping adaptation algorithm is an interference avoidance algorithm allowed by the U.S. FCC for ISM band spread spectrum systems. The frequency hopping adaptation algorithm is designed for ISM band frequency hopping systems such as IEEE 802.11 FH, HomeRF 2.0 (including wide band frequency...http://www.google.de/patents/US20030198280?utm_source=gb-gplus-sharePatent US20030198280 - Wireless local area network frequency hopping adaptation algorithm
