Method for communicating in dual-modes
First Claim
1. A method of communicating with a multi-mode communication protocol in a given frequency band composed of a plurality of channels, wherein a first set of the plurality of channels are designated fixed-frequency channels and a second set of the plurality of channels are designated spread-spectrum channels, the spread-spectrum channels being composed of a first subset of acquisition channels and a second subset of data channels, the method comprising:
- enabling communication in a spread-spectrum communication mode;
attempting to receive a communication packet by traversing through the subset of acquisition channels;
upon receiving a communication packet, switching to a data channel designated by the communication packet; and
receiving and verifying a data portion of the communication packet by communicating in the designated data channel;
upon not receiving a communication packet after traversing through the subset of acquisition channels, enabling communication in a fixed-frequency communication mode;
attempting to receive a communication packet by traversing through the designated fixed-frequency channels; and
upon receiving a communication packet, receiving and verifying a data portion of the communication packet by maintaining communication in the current fixed-frequency channel.

Abstract
The present invention is generally directed to methods for communicating in a dual-mode communication protocol. A representative embodiment of the present invention comprises: enabling communication in a spread-spectrum communication protocol, comprising: receiving a first portion of a communication frame at a first frequency channel, wherein the first portion of the communication frame comprises a data channel index that indicates a second frequency channel for receiving a second portion of the communication frame; switching to the second frequency channel; and receiving the second portion of the communication frame at the second frequency channel.
