Embodiment Construction

[0024] There is provided an encoded information reading (EIR) terminal incorporated into a data collection system. in the attached figure 1 The data collection system, shown schematically in , may include a plurality of EIR terminals 100a-100z in communication with a plurality of interconnected networks 110a-110z. In one aspect, the plurality of networks 110a-110z may include at least one IEEE 802.11 structured wireless network. In another aspect, the plurality of networks 110a-110z may include at least one GSM family wireless network, such as a wireless network supporting GSM, GPRS or EDGE wireless communication protocols. In a still further aspect, the plurality of networks 110a-110z may include at least one CDMA family wireless network, such as a wireless network supporting UMTS, HSPA or LTE wireless communication protocols. In a still further aspect, the plurality of networks 110a-110z may include at least one TDMA-family wireless network, such as a wireless network supp...

Abstract

A network-agnostic encoded information reading terminal can comprise a microprocessor, a memory communicatively coupled to the microprocessor, an EIR device, a multi-band antenna, and a wireless communication interface. The EIR device can be provided by a bar code reading device, an RFID reading device, and/or a card reading device. The EIR device can be configured to perform outputting raw message data comprising an encoded message and/or outputting decoded message data corresponding to an encoded message. The wireless communication interface can further comprise a radio frequency front end electrically coupled to the multi-band antenna. The wireless communication interface can be configured to support at least two wireless communication protocols. The microprocessor can be configured to execute a wireless communication protocol selector software program, which in turn can be configured to dynamically select a wireless communication network and/or a wireless communication protocol. Selection of a wireless communication network and/or a wireless communication protocol can be performed by optimizing a location-based criterion and/or a least cost routing criterion. The microprocessor can be configured to execute a system software program and/or an application software program in parallel with the wireless communication protocol selector software program switching a wireless communication network and/or a wireless communication protocol.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Patent Application No. 12 / 621914, filed November 19, 2009, and entitled "Network Code Agnostic Information Reading Terminal," claims priority to said application and is hereby incorporated in its entirety Incorporated by reference. technical field [0003] The present invention relates generally to encoded information reading (EIR) terminals, and more particularly to an EIR terminal including a multi-protocol wireless communication interface capable of seamlessly switching between wireless communication networks or protocols. Background technique [0004] Encoded information reading (EIR) terminals equipped with a wireless communication interface are widely used in retail stores, shipping facilities, and the like. Wireless communication of EIR terminals offers several advantages over wired communication, and conventional wired communication interfaces exhibit significant disadv...
