Abstract

Wireless communication techniques for controlling radio frequency (RF) interference among a plurality of wireless devices operating at a location include monitoring RF utilization at the location, receiving a request from a wireless device indicating that the wireless device wishes to operate using an RF interference control service and communicating, in response to the received request from the wireless device, a software module that provides access point functionality to the wireless device.

Claims (29)

1. An apparatus for controlling Wi-Fi radio frequency (RF) interference among a plurality of wireless devices operating at a location, comprising:

an interference monitoring module that monitors Wi-Fi radio frequency utilization at the location;

a device registration module that receives a request from a wireless device indicating that the wireless device wishes to operate using a Wi-Fi RF interference control service offered by the wireless communication apparatus; and

a download module that communicates, in response to the received request from the wireless device, a software module that provides Wi-Fi access point functionality to the wireless device and a message providing the access point functionality of the wireless device, when the wireless device possesses the access point functionality,

wherein the apparatus operates to control RF interference without providing internet connectivity and without providing data traffic routing capability to the plurality of wireless devices.

2. The apparatus of claim 1 , wherein the interference monitoring module monitors Wi-Fi RF utilization at the location based on detection of wireless signals to monitor spectral usage or receipt of reports from the wireless devices that include information about spectral interference measured at the wireless devices.

3. The apparatus of claim 1 , further comprising:

a channel selection module that assigns, for each registered wireless device, an RF channel for operation for the corresponding registered wireless device.

4. The apparatus of claim 3 , wherein the channel selection module is further configured to assign the RF channel for operation based on a Quality of Service desired by the registered wireless device and an air interface protocol version capability of the registered wireless device.

5. An apparatus for controlling Wi-Fi radio frequency (RF) interference among a plurality of wireless devices operating at a location, comprising:

an interference monitoring module that monitors Wi-Fi radio frequency utilization at the location;

a device registration module that receives a request from a wireless device indicating that the wireless device wishes to operate using a Wi-Fi RF interference control service offered by the wireless communication apparatus;

a download module that communicates, in response to the received request from the wireless device, a software module that provides Wi-Fi access point functionality to the wireless device and a message providing the access point functionality of the wireless device, when the wireless device possesses the access point functionality;

a spectrum use receive module that receives reports from the wireless devices, the reports comprising information about spectral interference measured at the wireless devices, including transmission power used by the wireless devices; and

a topology determination module that determines, based on the received reports from the wireless devices, an RF obstruction at the location.

6. The apparatus of claim 5 , further comprising:

a relay configuration module that controls operation of one of the wireless devices to operate in a relay mode to provide wireless connectivity to another one of the wireless devices across the RF obstruction.

7. The apparatus of claim 5 , further comprising:

a relay configuration module that controls operation of one of the wireless devices to operate in a relay mode to provide wireless connectivity to another one of the wireless devices that is outside a transmission range of the access point.

8. A non-transitory computer program product comprising a non-transitory computer-readable medium having code stored thereon, the code, when executed, causing a processor to implement a method of Wi-Fi wireless communication, the method comprising:

requesting admission to a wireless network for establishing an initial Wi-Fi Internet connectivity;

monitoring, upon admission, a Quality of Service (QoS) of the initial Wi-Fi Internet connectivity;

exiting the wireless network when the QoS falls below an acceptability threshold; and

requesting re-establishing a subsequent Wi-Fi Internet connectivity over the wireless network, after the exiting, using an interference controlled operational mode that was not used for establishing the initial Internet connectivity.

9. The computer program product of claim 8 , wherein the method further comprises:

receiving a software module; and

executing the software module to implement the interference controlled operational mode when transmitting and receiving data in the wireless network.

10. The computer program product of claim 9 , wherein the method further comprises:

transmitting information indicative of an amount of radio frequency interference estimated on a wireless channel of operation.
