First Claim
1. An encoded information reading (EIR) terminal comprising:
- a central processing unit (CPU);
a memory communicatively coupled to said CPU;
an encoded information reading (EIR) device selected from the group consisting of a bar code reading device, an RFID reading device, and a card reading device, said EIR device configured to perform one of;
outputting raw message data containing an encoded message, outputting decoded message data corresponding to an encoded message; and
a wireless communication interface communicatively coupled to said CPU, said wireless communication interface comprising a first logical communication interface operating on a first frequency channel and a second logical communication interface operating on a second frequency channel;
wherein said wireless communication interface is configured to transmit infrastructure mode beacons on said first frequency channel, said infrastructure mode beacons including a service set identifier;
wherein said wireless communication interface is further configured to transmit ad-hoc mode beacons on said second frequency channel, said ad-hoc mode beacons including an identifier of a mesh path selection protocol; and
wherein said EIR terminal is further configured to route MAC frames between said first logical communication interface and said second logical communication interface.

Abstract
An encoded information reading (EIR) terminal can comprise a central processing unit (CPU), a memory communicatively coupled to the CPU, an EIR device, and a wireless communication interface communicatively coupled to the CPU. The EIR device can be selected from the group consisting of a bar code reading device, an RFID reading device, and a card reading device. The EIR device can be configured to perform one of: outputting raw message data containing an encoded message, outputting decoded message data corresponding to an encoded message. 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.
