60 GHz Extension of WLAN/PAN Solutions– An Example Based on Broadway
• The Broadway Vision:– Extend and complement 5GHz WLAN with 60 GHz to provide a solution in dense urban environments wi
th hot spot coverage without sacrificing throughput– Provide backward compatibility with existing 5 GHz OFDM solutions– Provide total system throughput >400 Mbps via bandwidth expansion
• An Example Architecture:– Access points (AP) utilize full-time dual band operation– Mobile terminals (MT) utilize one band at a time– Employ Rx omni antenna to avoid MT pointing – Employ AP transmission from remote locations for full coverage – OFDM can tolerate multipath

Current Movement within ETST BRAN
In September 2003 meeting, there was a presentation from a BROADWAY rep. to create a working group within ETSI BRAN to study the extension of existing WLANs and WPANs in the 60GHz band. (doc# : bran34d018)
In September BRAN meeting, IEEE802.15.mm-WIG has been introduced.
European frequency issues are under investigation for next BRAN meeting.
Following companies have already expressed their support for the creation of 60GHz working group in BRAN(Motorola, France Telecom, Intracom, Thomson Multimedia, CEA LETI, IMST, TNO)
