Integrated self-optimizing multi-parameter and multi-variable point to multipoint communication system
First Claim
1. A method of transmitting data in a point to multipoint wireless network including a base station with two or more antennas and one or more customer premises equipment (CPE), each with two or more antennas, the method comprising:
- maintaining a set of parameters for wireless communication between the base station and each CPE;
establishing wireless communication between the base station and the one or more CPEs using the respective set of parameters; and
independently adapting the set of parameters for use with each CPE based on changing conditions in the wireless communication between the base station and the respective CPE;
wherein adapting the set of parameters includesselecting an antenna selection parameter to indicate how the base station transmits a communication signal from the two or more antennas of the base station to the two or more antennas of the respective CPE andselecting a power level and modulation type pair for transmission from the base station to the CPE.

Abstract
The invention provides a method and system for adaptive point to multipoint wireless communication. The wireless physical layer and the wireless media-access-control (MAC) layer collectively include a set of parameters, which are adaptively modified by a base station controller for communication with a plurality of customer premises equipment. The base station controller adjusts communication with each customer premises equipment individually and adaptively in response to changes in characteristics of communication, including physical characteristics, amount of communication traffic, and nature of application for the communication traffic.
