Modular, portable data processing terminal for use in a communication network
CAFCFirst Claim
1. One or more circuits adapted for use in a mobile computing device comprising:
- a terminal adapted to receive battery power for at least one of the circuits;
communication circuitry comprising a reduced power mode and being adapted to use a first wireless communication and a second wireless communication different from the first wireless communication to transmit data to access points, the communication circuitry reducing power by controlling the frequency of scanning for the access points; and
processing circuitry arranged to process data received from the communication circuitry.

Abstract
A portable data terminal includes at least two communication transceivers having different operating characteristics, one for conducting data communications on a wired subnetwork and one for conducting data communications on a wireless subnetwork. A communication processor converts data received by the communication transceivers to a predetermined format for a base module and converts data in a predetermined format from the base module to a format for transmission by a selected one of the first and second communication transceivers, thereby isolating the base module from differing characteristics of the transceivers. The communication processor is arranged to relay communications received by one transceiver for re-transmission by the other transceiver and to transfer communications from one subnetwork to the other, without activating the base module.

14. A method for use in a mobile computing device to communicate with access points comprising:
-
receiving battery power;
using the battery power to transmit data to the access points and receive data from the access points using a first wireless communication and a second wireless communication different from the first wireless communication;
reducing the received battery power by controlling the frequency of scanning for the access points; and
processing data received from the first wireless communication and the second wireless communication. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
reducing the received battery power when the transmitting of data or the receiving of data is not needed; and
increasing the received battery power when the transmitting of data or the receiving data is needed.
