WIRELESS COMMUNICATION PROTOCOL FOR LOW POWER RECEIVERS
First Claim
Patent Images
1. A method for wireless data communication, the method comprising the steps of:
- assembling a message frame, the message frame including a synchronization word, an address word and a data word;
repeatedly transmitting the message frame from a wireless transmitter for a minimum transmission duration;
at a receiver, periodically searching for a predetermined synchronization word in the transmitted message frame, the duration of each synchronization search being at least as long as the length of the message frame plus the length of one synchronization word minus one symbol;
at the receiver, determining if a transmitted message frame includes a synchronization word that corresponds to the predetermined synchronization word; and
at the receiver, decoding the transmitted message frame only if the predetermined synchronization word is found.

Abstract
A wireless protocol for a communication system is set forth herein which may be utilized for communication between a transmitter and a receiver over any type of communication channel. The wireless communication protocol provides for the reduction of receiver active or on time which in turn lowers power consumption. The wireless communication protocol enables the complexity and receiver size to be reduced. The methodology employed in the protocol utilizes a unique message frame in conjunction with repeated transmission and periodic receiver searching.
