Assignee:

Intermec IP Corp. - Everett WA

International Classification:

H04M 1/00

US Classification:

4555751, 455 73, 455 741, 455 75, 455 91, 455 95, 455103, 455113, 455123, 455429, 375346

Abstract:

A wireless communication system having a terminal unit operates in a reduced noise state during receipt of a wireless transmission from a control unit. The terminal unit includes terminal circuitry, a radio and noise management circuitry. The noise management circuitry partially or fully disables operation of the terminal circuitry during a receipt by the radio. Noise management circuitry may disable a terminal processor, disable interrupts, buffer interrupts and otherwise modify operation of the terminal circuitry to reduce generated radio noise that would otherwise interfere with receipt of data by the radio. The wireless communication system includes noise management circuitry located in a control unit that operates in conjunction with noise management circuitry in a first terminal unit and a second terminal unit to schedule transmissions from the control unit. These scheduled transmissions allow the terminal units to perform required processing functions outside of the reduced noise period.
