There are two types of HiperLAN:

• HiperLAN/1: provides communications at up to 20 Mbps in the 5 GHz band.
• HiperLAN/2: provides communications at up to 54 Mbps in the 5 GHz band.

Like 802.11, HiperLAN serves to ensure the possible interoperability of different manufacturers' wireless communications equipment that operate in this spectrum.

Also see the Wireless LAN Standards chart in the Quick Reference section of Webopedia.
