A portable encoded information reading (EIR) terminal for incorporation in a data collection system can comprise a terminal module communicatively coupled to a wireless interface module via a wired interface. The wireless interface module can establish one or more wireless links with one or more peer EIR terminals. The wireless interface module can receive or transmit beacons containing at least an identifier of a path selection protocol which is used for unicast, multicast and broadcast frame transmission within the wireless network. The wireless interface module, responsive to receiving a MAC frame from the terminal module, can forward the MAC frame, according to the path selection protocol, to a peer EIR terminal or to a portal which is capable of routing MAC frames between the wireless network and one or more OSI layer 2 networks.
