Mechanism and technique for dynamically optimizing antenna orientation and transmit power in a meshed network environment
First Claim
25. A method for dynamically tuning a directional antenna of a wireless device for communicating with an access point in a short-range wireless networking environment, comprising the steps of:
- providing at least one wireless device;
providing at least one access point;
establishing a network link between a selected one of the wireless devices and a selected one of the access points using the directional antenna of the selected wireless device and an omnidirectional antenna of the selected access point; and
setting a position of the directional antenna to minimize a bit error rate along the established link.

Abstract
The present invention provides methods, systems, devices, and computer program instructions for enabling low-power wireless devices (such as wireless telephones and personal digital assistants, or PDAs) to connect to a fast wired or wireless voice/data network. A novel relay point device, referred to as an “extension point”, is defined that flexibly extends the effective reach of network access points. Use of extension points enables the network infrastructure to be expanded (and subsequently re-configured, if necessary) simply and cost-effectively, requiring little or no additional physical wiring. The defined techniques provide an infrastructure that is scalable, supporting a large number of end users without substantial degradation to connection establishment time and data rates. Using the disclosed techniques, end devices are able to reach network services, and to communicate with other end devices, beyond the nominal working range of these devices and without limitation to the numbers of such devices.
