Abstract
A local area network system includes a wired backbone LAN (12) and at least one wireless LAN (14) cooperating with the backbone LAN (12) via an access point (22), which has a bridging function. When a source station (30) in the wireless LAN (14) transmits a packet to another station in the wireless LAN (14), the destination station should respond with an ACK signal. If no ACK signal is received by the source station, the packet is retransmitted. The access point (22) also receives the transmitted packet and if the access point (22) does not detect an ACK signal on the wireless channel', the access point (22) itself generates an ACK signal and retransmits the packet on the wireless LAN (14) or forwards the packet to the wired LAN (12) according to the packet destination address.
