HIPERLAN

(HIgh PERformance Radio LAN) A wireless LAN protocol developed by the European Telecommunications Standards Institute (ETSI) that is similar in function to Wi-Fi in the U.S. HIPERLAN/1 and HIPERLAN/2 offer 20 and 54 Mbps data rates respectively in the 5 GHz band. Unlike 802.11a, HIPERLAN provides quality of service (QoS), which lets critical traffic be prioritized.

Faster HIPERLANs
HIPERACCESS (High Performance Radio Access) and HIPERMAN (High Performance Radio MAN) are designed for broadband speeds and greater ranges than HIPERLAN/2. HIPERACCESS provides up to 100 Mbps in the 40.5-43.5 GHz range, and HIPERMAN is designed for wireless metropolitan area networks (MANs) in the 2 GHz and 11 GHz bands. See wireless LAN and ISM band.
