AP-51xx Access Point Product Reference Guide
The access point (AP) provides a bridge between Ethernet wired LANs or WANs and wireless
networks. It provides connectivity between Ethernet wired networks and radio-equipped mobile units
(MUs). MUs include the full line of terminals, adapters (PC cards, Compact Flash cards and PCI
adapters) and other devices.
The access point provides a maximum 54Mbps data transfer rate via each radio. It monitors Ethernet
traffic and forwards appropriate Ethernet messages to MUs over the network. It also monitors MU
radio traffic and forwards MU packets to the Ethernet LAN.
