Encoded information reading terminal with wireless path selecton capability
First Claim
1. An encoded information reading (EIR) terminal, comprising:
- a terminal module including a central processing unit (CPU), a memory, and an encoded information reading (EIR) device, the EIR device configured to output raw message data;
a wireless interface module communicatively coupled to the terminal module via a wired interface, the wireless interface module including a microcontroller, a memory, and at least one wireless communication interface;
wherein the wireless interface module is configured to establish one or more wireless links with one or more peer EIR terminals to join a wireless network of peer EIR terminals; and
wherein the wireless interface module is configured, responsive to receiving a portal announcement, to cache one or more network addresses of devices having originated the portal announcement.

Abstract
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.
