[HyperLAN] stands for "High Performance Radio Local Area Network", and is a [WLAN Wireless LAN] standardised by the European Telecommunication Standardisation Institution ([ETSI]).



[HyperLAN] runs in the 5 GHz ISM band, and has a theoretical maximum speed of 54 Mbps. [HyperLAN] is a competitor to [802.11a] technology, and is, of course, adopted widely in Europe (and is one main reason for the [ETSI] to disallow [802.11a] use across Europe, for now).



The [ACA] supports [HyperLAN]'s, however under the same restricted "low interference potential devices class licence" as [802.11a].
