First Claim
1. A method of limiting interference in a local wireless network, comprising:
- transmitting a first wireless signal within the local wireless network using a first set of transmission parameters;
performing a first signal analysis to determine whether the signal quality of the first wireless signal is above a quality threshold;
adjusting the first set of transmission parameters in the local wireless network to a second set of transmission parameters if the signal quality is below the quality threshold;
transmitting a second wireless signal within the local wireless network using the first set of transmission parameters if the signal quality is determined to be above the quality threshold in the step of performing a first signal analysis; and
transmitting a second wireless signal within the local wireless network using the second set of transmission parameters if the signal quality is determined to be below the quality threshold in the step of performing a first signal analysis,wherein the first transmission parameters include a first transmission phase and a first set of code words used to encode data,wherein the second transmission parameters include a second transmission phase and a second set of code words used to encode data, andwherein the second transmission phase is the same as the first transmission phase and the second set of code words is different from the first set of code words.

Abstract
A multiple step process is performed at a local wireless network to limit interference between the local wireless network and a remote wireless network. Initially, a set of code words is chosen for the local wireless network to encode data with that have good cross correlation properties. If these initial code words are not adequate to prevent interference, then the local wireless network will adjust its transmission parameters by either shifting the transmission phase of its signals or by changing the code words it uses. If altering the transmission parameters does not alleviate the interference problem, then the local wireless network attempts to locate the interfering remote network and merge with it. If the merger is not possible or is unsuccessful, then the interference limiting process fails.
