Distributed infrastructure for wireless data communications
First Claim
1. A wireless data communication system apparatus, comprising:
- a network access point configured to;
communicate with at least two of a plurality of routers; and
communicate with at least one remote user; and
a control point co-located with said network access point and configured to control communications between at least two network access points and said at least one remote user, wherein the control point is configured to manage power control of said remote user'"'"'s transmit power and handoff of said remote user from said network access point to another network access point.

Abstract
A mobile user terminal 402 accesses a packet data network 450 through one or more of several network access points 404-412. One or more control points 432-440 determines which network access point or points the user terminal is to access. Control may be retained in the current control point, or transferred to another control point, whenever it is convenient. There are preferably several routers, each having an associated home agent 418-420 which determines which foreign agents need to be accessed on behalf of each user terminal. There are several foreign agents 422-430, which forward packets received from a user terminal'"'"'s home agent to the control point currently controlling communications with the user terminal.
