Abstract
Wireless networks in ISM bands are usually established by placing access points that link terminals to each other and to networks. This situation may pose problems when networks are established individually without coordination, for example, in different apartments of apartment buildings. According to the present invention, access points establish a communication channel, linking each other, to cooperatively coordinate and optimize the use of frequencies/channels. Advantageously, interferences occurring in such networks may be reduced.
Claims12
Wireless network system, comprising:
- a first access point for providing a first communication channel to a first terminal;
- and a second access point for providing a second communication channel to a second terminal;
- wherein the first access point is adapted to build up a third communication channel to the second access point to coordinate a setting of the first and second communication channels.
Access point device for a wireless network system, wherein the access point device is adapted to:
- provide a first communication channel to a terminal;
- and build up a second communication channel to another access point to coordinate a setting of the first communication channel.
Method of operating an access point of a wireless network, the method comprising the steps of:
- providing a first communication channel to a terminal;
- and building up a second communication channel to another access point to coordinate a setting of the communication channel.
