Modular, portable data processing terminal for use in a radio frequency communication network
First Claim
1. A communication device utilizing a communication protocol having higher and lower layers, the device comprising a wireless transceiver, the device comprising:
- a memory operable to store the higher layers of the communication protocol; and
a processor operable to cooperate with the wireless transceiver to effect wireless communication by the wireless transceiver, the processor being operable to perform the functionality of the higher layers of the communication protocol stored in the memory.

Abstract
Modular, portable data collection terminals are disclosed for use in mixed wireless and hard-wired RF communication networks, wherein various radio transmitter modules and associated antennas may be selectively added to a base terminal unit to solve networking problems associated with specific types of business environments. Modularity exists in both the hardware (splitting data collection and processing control circuitry from radio transceiver control circuitry) and software (splitting transceiver specific, lower level communication protocol from generic, higher level communication protocol). The control circuitry, including associated microprocessors devices, interact to selectively activate communication circuits to perform necessary communication or data processing functions and enter and remain in a power-saving dormant state during other times. To support such dormant or “sleeping” states, a series of communication protocols provide for channel access to the communication network.
