Abstract
A wireless LAN technology for reducing interference between (or among) wireless LAN access points is provided. A wireless LAN access point is provided with a directional antenna, an interference detector detecting interference effected by another wireless LAN access point on the directional antenna, and a direction adjusting mechanism adjusting a maximum gain direction of the directional antenna in response to the detected interference.
Claims5
A wireless LAN access point comprising:
- an interference detector detecting interference effected by other wireless LAN access points;
- a channel selector switching a plurality of channels used to communicate with a terminal;
- and
- a signal processor,
- wherein, in response to detection of interference on one of said plurality of channels during communications through said one channel, said channel selector selects another channel from among said plurality of channels which receives least interference from said other wireless LAN access points, and
- wherein said signal processor communicates with said terminal through said selected channel.
A method for avoiding interference between wireless LAN access points, comprising:
- detecting interference between first and second wireless LAN access points;
- and
- moving an electromagnetic shield between said first and second wireless LAN access points in response to occurrence of said interference.
A method for operating a wireless LAN access point adapted to communicate with a wireless LAN adapter through a plurality of channels, said method comprising:
- detecting interference from another wireless LAN access point;
- selecting one channel from among said plurality of said channels so that said selected channel eliminates or minimizes said interference;
- and
- achieving communications with said wireless LAN adapter through said selected channel.
