Abstract
A household appliance, such as a microwave oven or cordless phone, reduces interference with a wireless network by requesting control of the network's channel during a period of time when the appliance will be emitting signals that may interfere with network communications on that channel. Some embodiments contend for the channel before transmitting the request by using standard protocols, while other embodiments simply transmit the request during a detected idle period. Some embodiments don't bother sending a request if no activity is detected on the channel.
Claims25
An apparatus, comprising
- an appliance comprising:
- a first device for emitting radio frequency (RF) signals at a particular time and at a frequency used by a particular wireless channel;
- and
- a second device, coupled to the first device, for wirelessly transmitting and receiving data within a network on the particular wireless channel;
- wherein the second device is to transmit particular data to a network node, requesting use of the particular wireless channel at the particular time.
2 more elements
A method, comprising:
- determining that a radio frequency (RF) signal is due to be emitted from an appliance during a particular time interval;
- and
- transmitting a request to use a wireless channel during the particular time interval, the wireless channel using a same frequency as at least part of the RF signal.
An article comprising
- a tangible machine-readable medium that contains instructions, which when executed by one or more processors result in performing operations comprising:
- determining that a radio frequency (RF) signal is due to be emitted from an appliance during a particular time interval;
- and
- transmitting a request to use a wireless channel during the particular time interval, the wireless channel using a same frequency as at least part of the RF signal.
