MODAL ANTENNA BASED COMMUNICATION NETWORK AND METHODS FOR OPTIMIZATION THEREOF

摘要

A communication network is optimized using modal antenna techniques, wherein a plurality of communication nodes are synchronized with each other along with mobile and fixed wireless communication devices which comprise the user base. With one or more of the communication nodes and wireless communication devices including at least one respective modal antenna, the network is adapted for dynamic optimization of communication links amongst the wireless users. Node to user throughput, node to node throughput, as well as interference characteristics among the nodes and wireless users are each optimized as a network system to increase communication system network capacity and reliability. The multiple radiation patterns provided by the modal antennas provide a parametric for network-level synchronization to improve communication system performance.

1. In a communication network having one or more wireless communication devices coupled to one or more communication nodes, at least one of the communication nodes including a modal antenna configured to produce a distinct radiation pattern when configured in each of a plurality of possible antenna modes thereof, a method for optimizing communication link performance between one or more of the nodes and devices within the communication network, the method comprising:
with a first communication node comprising a first modal antenna, the first modal antenna in a first mode of the plurality of possible antenna modes thereof:
using the first modal antenna in the first mode to survey an environment within range of the first communication node to determine a first signal level achieved with each other communication node and each wireless communication device within said range;populating a matrix of data with the first signal levels for each of the surveyed nodes and devices corresponding to the first mode of the modal antenna; reconfiguring the first modal antenna in a second mode of the plurality of possible antenna modes thereof:
using the first modal antenna in the second mode to survey the environment within range of the first communication node to determine a second signal level achieved with each other communication node and each wireless communication device within said range;further populating the matrix of data with the second signal levels for each of the surveyed nodes and devices corresponding to the second mode of the modal antenna; and selecting a preferred mode of the first modal antenna based on the matrix of data, wherein the preferred mode provides optimal link performance and minimized interferers within the communication network.
