Abstract

An encoded information reading (EIR) terminal can comprise a central processing unit (CPU), a memory an EIR device, and a wireless communication. The EIR device can be provided by a bar code reading device, an RFID reading device, and/or a card reading device. The wireless communication interface can comprise a first logical communication interface operating on a first frequency channel and a second logical communication interface operating on a second frequency channel. The wireless communication interface can be configured to transmit infrastructure mode beacons. The infrastructure mode beacons can include a service set identifier. The wireless communication interface can be further configured to transmit ad-hoc mode beacons on the second frequency channel. The ad-hoc mode beacons can include an identifier of a mesh path selection protocol. The EIR terminal can be further configured to route MAC frames between the first logical communication interface and the second logical communication interface.
