Abstract
Detecting interference between neighboring Basic Service Sets (BSSs) in a Wireless Local Area Network (WLAN) system conforming to an IEEE 802.11 standard in which an arbitrary Access Point (AP) wirelessly transmits and receives frames to and from a station in a relevant BSS includes: receiving the frames; calculating an other-BSSID rate for the received frames; and determining whether interference has occurred, based on the other-BSSID rate.
Claims19
An apparatus to detect interference between neighboring Basic Service Sets (BSSs) in a Wireless Local Area Network (WLAN) system in which an arbitrary Access Point (AP) wirelessly transmits and receives frames to and from a station in a relevant BSS, the apparatus comprising:
- an other-BSSID rate calculator adapted to calculate a rate of frames containing an IDentifier (ID) of the relevant BSS and other BSSID (BSS IDentifier) among all of the received frames;
- and
- an interference detector adapted to determine whether interference between the BSSs has occurred, based on the other-BSSID rate calculated by the other-BSSID rate calculator.
An apparatus adapted to detect interference in an Access Point (AP) wirelessly transmitting and receiving frames to and from a station in a Basic Service Set (BSS) in a Wireless Local Area Network (LAN) system conforming to an IEEE 802.11 standard, the apparatus comprising:
- an other-BSSID rate calculator adapted to calculate a rate of frames containing an other-BSSID (BSS IDentifier) among all of the received frames;
- an interference detector adapted to determine whether interference between the BSSs has occurred, based on the other-BSSID rate calculated by the other-BSSID rate calculator;
- and
- a channel switch adapted to switch a channel assigned for frame transmission and reception in response to the interference detector determining that interference has occurred.
An apparatus adapted to detect interference in a station wirelessly transmitting and receiving frames to and from an Access Point (AP) in a Basic Service Set (BSS) of a Wireless Local Area Network (LAN) system conforming to an IEEE 802.11 standard, the apparatus comprising:
- an other-BSSID rate calculator adapted to calculate a rate of frames containing an other-BSSID (BSS IDentifier) among all of the received frames;
- an interference detector adapted to determine whether interference between the BSSs has occurred, based on the other-BSSID rate calculated by the other-BSSID rate calculator;
- and
- a channel switch adapted to transmit a signal to the AP to request channel switching in response to the interference detector determining that interference has occurred.
A method of detecting interference between neighboring Basic Service Sets (BSSs) in a Wireless Local Area Network (WLAN) system conforming to an IEEE 802.11 standard in which an arbitrary Access Point (AP) wirelessly transmits and receives frames to and from a station in a relevant BSS, the method comprising:
- receiving the frames;
- calculating an other-BSSID rate for the received frames;
- and
- determining whether interference has occurred, based on the other-BSSID rate.
