Abstract
The present invention relates to an apparatus and a method for avoiding signal interference between access points (APs) in a non-license band, and more particularly, an interference avoidance apparatus and method between access points (APs) that avoid interference based on whether an overlapping basic service set (OBSS) is present, whether an overlapping operation channel between adjacent APs is used, whether it is possible to select a non-overlapping operation channel between adjacent APs, and the like.
Claims13
An apparatus for avoiding interference between access points (APs), the apparatus comprising:
- an adjacent AP presence determining unit configured to determine whether a second AP adjacent to a first AP is present;
- an operation channel overlapping determining unit configured to determine whether an operation channel of the first AP and an operation channel of the second AP overlap, when the second AP is determined to be present;
- a non-overlapping channel setting determining unit configured to determine whether setting of a non-overlapping operation channel is possible when the operation channel of the first AP and the operation channel of the second AP are determined to overlap;
- and
- a channel use controlling unit configured to control the operation channel of the first AP to be shared with the second AP when setting of the non-overlapping operation channel is determined to be impossible.
A method for avoiding interference between APs, the method comprising:
- an adjacent AP presence determining operation of determining whether a second AP adjacent to a first AP is present;
- an operation channel overlapping determining operation of determining whether an operation channel of the first AP and an operation channel of the second AP overlap, when the second AP is determined to be present;
- a non-overlapping channel setting determining operation of determining whether setting of a non-overlapping operation channel is possible when the operation channel of the first AP and the operation channel of the second AP are determined to overlap;
- and
- a channel sharing controlling operation of controlling the operation channel of the first AP to be shared with the second AP when setting of the non-overlapping operation channel is determined to be impossible.
