Use of dual asymmetric wireless links to provide bi-directional high data rate wireless communication
First Claim
1. A method comprising:
- providing a first asymmetric wireless data link between a first node and a second node, wherein the first asymmetric wireless data link defines a first high-data-rate link for carrying data from the first node to the second node and a first low-data-rate link for carrying data from the second node to the first node;
providing a second asymmetric wireless data link between the second node and the first node, wherein the second asymmetric wireless data link defines a second high-data-rate link for carrying data from the second node to the first node and a second low-data-rate link for carrying data from the first node to the second node; and
concurrently operating the first asymmetric wireless data link and the second asymmetric wireless data link so as to provide bi-directional high-data-rate wireless communication between the first node and the second node,wherein the first high-data-rate link and the second high-data-rate link both carry forward link communications including communications directed from a given base station to a given mobile station, wherein the first node and the second node function as both the given base station and the given mobile station simultaneously.

Abstract
To provide high-data-rate wireless communication in both directions between a pair of nodes, the present invention provides for operating at least two asymmetric wireless connections in parallel but in reverse directions between the nodes. One of the asymmetric wireless connections will provide a high-data-rate forward link in one direction between the nodes, while the other asymmetric wireless connection will concurrently provide a high-data-rate forward link in the other direction between the nodes. The lower-data-rate reverse links provided by the asymmetric wireless connections can then be used to carry overhead control data or can be used to supplement the primary high-data-rate communication provided by the forward links. Preferably, 1xEV-DO will be used for both asymmetric wireless data links, but other asymmetric air interface protocols could be used instead.
