Electronic device with wireless path selection capability

摘要

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 terminal module can include a central processing unit (CPU), a memory, and an encoded information reading (EIR) device. The wireless interface module can include a microcontroller, a memory, and at least one wireless communication interface. The wireless interface module can establish one or more wireless links with one or more peer EIR terminals, to join a wireless network which is collectively formed by the 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.
