Roaming encoded information reading terminal
First Claim
1. An encoded information reading (EIR) terminal, comprising:
- a central processing unit (CPU); and
an EIR device in communication with the CPU and configured for outputting message data comprising decoded message data and/or raw message data;
wherein the EIR device comprises a symbol-reading device, an RFID-reading device, and/or a card-reading device;
wherein the EIR terminal is configured for;
transmitting a registration request to a home agent, the registration request comprising a care-of address and an authentication extension for authenticating the EIR terminal to the home agent; and
when roaming from a first network to a second network, maintaining an active communication session with a remote host computer using a home address for addressing the EIR terminal when providing data of an active communication session across the first network and the second network, the home address belonging to an associated address range of a home network.

Abstract
A portable encoded information reading (EIR) terminal for incorporation in a data collection system having a host computer, a plurality of peer EIR terminals, and a plurality of interconnected networks including one or more wireless networks, can comprise a central processing unit (CPU), a memory, an encoded information reading (EIR) device configured to output raw message data containing an encoded message or decoded message data corresponding to an encoded message, and at least one wireless communication interface. The EIR terminal can provide IEEE 802.11-conformant wireless distribution system services, including association, disassociation, distribution, integration, and re-association, to the peer EIR terminals. The EIR terminal can be associated with a home network and have a home address belonging to the address range associated with the home network.
