Abstract
The present invention provides systems and methods are provided to allow a network device to simultaneously monitor multiple adjacent wireless physical layer channels. If network communications are discovered on an adjacent channel, the network device may move to this adjacent channel. Accordingly, the network device is able to discover other devices or services existing on the adjacent channel, and is able to avoid interference caused by adjacent channels coexisting on the same frequency bands. After moving to the adjacent channel, a standard MAC protocol is able to regulate channel excess amongst all the network devices coexisting on the new channel.
Claims14
A method for network communication, comprising:
- a first network device wirelessly communicating with a second network device using a first channel and simultaneously scanning a range of further channels for wireless communications between further network devices, the wireless communications causing interference on the first channel;
- if wireless communications between further network devices are detected on a second channel of the range of further channels, the first network device communicating with the second network device using the second channel according to an access protocol signal transmitted on the second channel by at least one of the further network devices;
- detecting a service or a further network device on the second channel;
- and
- utilizing the service or communicating with the further network device according to a media access protocol.
An apparatus for network communication and signal detection, comprising:
- a receiver module configured to receive data from a network device on a first physical layer channel;
- and
- a second receiver module configured to simultaneously scan a range of further physical layer channels for further wireless network communications, the further wireless network communications causing interference on the first physical layer channel;
- wherein
- the apparatus is configured to communicate with the network device using a second channel according to an access protocol signal transmitted on the second channel if further wireless network communications are detected on the second channel;
- the second receive module is further configured to detect a service or a further network device on the second channel;
- and
- the apparatus is further configured to utilize the service or communicate with the further network device according to a media access protocol.
Computer executable program code embodied on a computer readable medium configured to cause a first network device to perform the functions of:
- the first network device wirelessly communicating with a second network device using a first channel and simultaneously scanning a range of further channels for wireless communications between further network devices, the wireless communications causing interference on the first channel;
- if wireless communications between further network devices are detected on a second channel of the range of further channels, the first network device communicating with the second network device using the second channel according to an access protocol signal transmitted on the second channel by at least one of the further network devices:
- wherein:
- the computer executable program code is further configured to cause the device to perform the function of:
- detecting a service or a further network device on the second channel;
- and
- utilizing the service or communicating with the further network device according to a media access protocol.
