TECHNIQUES FOR WIRELESS DEPLOYMENT
First Claim
1. A wireless network, comprising a plurality of access devices for enabling wireless access to the network by a plurality of client devices, a first one of the access devices being configured to inhibit association of the client devices with the first access device at data rates below a predetermined data rate, thereby creating a zone of operation outside of which the client devices are unlikely to associate with the first access device.

Abstract
A variety of techniques are described in which wireless access points or base stations are deployed in wireless networks to achieve geographic isolation, i.e., distinct zones of operation having well-defined geographic boundaries, and increased overall capacity in an area having a high population of access and client devices.

- 1. A wireless network, comprising a plurality of access devices for enabling wireless access to the network by a plurality of client devices, a first one of the access devices being configured to inhibit association of the client devices with the first access device at data rates below a predetermined data rate, thereby creating a zone of operation outside of which the client devices are unlikely to associate with the first access device.

3. A wireless network, comprising a plurality of access devices for enabling wireless access to the network by a plurality of client devices, each of the access devices being configured to transmit probes to the client devices and to receive responses from the client devices corresponding to the probes, a first one of the access devices being configured to inhibit association of the client devices with the first access device where receipt of the responses occurs more than a predetermined time period after transmission of the corresponding probes, thereby creating a zone of operation outside of which the client devices are unlikely to associate with the first access device.
- 4. A wireless network, comprising a plurality of access devices for enabling wireless access to the network by a plurality of client devices, each of the access devices being configured to transmit probes to the client devices and to receive responses from the client devices corresponding to the probes, a first one of the access devices being configured to determine distances from the first access device to the client devices with reference to time periods associated with the probes and the corresponding responses.
- 8. A wireless network, comprising a plurality of access points for enabling wireless access to the network by a plurality of client devices, a first one of the access points being configured to facilitate association of the client devices with the first access point by broadcasting a first set of service set identifiers, the first access point further being configured to facilitate association of selected ones of the client devices in response to transmissions from the selected client devices identifying additional service set identifiers not included in the first set of service set identifiers.
- 14. A wireless network, comprising a plurality of access devices for enabling wireless access to the network by a plurality of client devices, first ones of the access devices being configured to transmit signals having a first polarization, and second ones of the access devices being configured to transmit signals having a second polarization different from the first, wherein the first and second access devices are deployed to mitigate friendly interference among the access devices.
