为了满足未来的Internet访问和宽带多媒体数据业务的需求，一些标准化组织开发了新一代的WLAN技术标准。其中最有代表性的是美国的IEEE 802.11a和欧洲ETSI的HIPERLAN，后者在5GHz的频段上运行，而传统的无线局域网技术大多使用2.4GHz频段。早期的HIPERLAN（即HIPERLAN1）采用GM
To meet future Internet access and broadband multimedia data services needs, some standardization organizations have developed a new generation of WLAN technology standards. The most representative of these are the IEEE 802.11a in the United States and the HIPERLAN in the European ETSI, which operates on the 5GHz band, whereas traditional wireless LANs mostly use the 2.4GHz band. Early HIPERLAN (ie HIPERLAN1) GM
