AccessPointUG.book Page 13 Thursday, February 27, 2003 12:22 PM [Final Draft—Nortel Confidential] 13 Preface Introduction The Nortel Networks Wireless LAN Access Point 2220 (Access Point 2220) is an access point that provides transparent, wireless high-speed data communications between the wired LAN and fixed, portable or mobile devices equipped with an 802.11a/802.11b (or A only card or B only card) wireless adapter employing the same radio modulation.
AccessPointUG.book Page 14 Thursday, February 27, 2003 12:22 PM [Final Draft—Nortel Confidential] 14 Preface The access point appears as an Ethernet node and performs a routing function by moving packets from the wired LAN to remote workstations on the wireless infrastructure. Radio Characteristics For the A radio, the Access Point 2220 uses a radio modulation technique known as Orthogonal Frequency Division Multiplexing (OFDM), and a shared collision domain (CSMA/CA).
