Abstract
The present disclosure is directed towards a device and a method for evaluating a wireless link (3) of a wireless node of a customer premises equipment (CPE) device (1, 2) during operation of the CPE device. The device and method includes determining an actual data rate (33) of the wireless link, determining an available data rate (31) of the wireless link, and calculating a headroom (34) based on a required data rate (30) and the available data rate (31).
Claims14
A method implemented by an Access Point (AP) for evaluating a plurality of wireless links between a plurality of stations and the AP, wherein each station of the plurality of stations has one wireless link of the plurality of wireless links to the AP, the method comprising:
- measuring an actual data rate, exclusively from the AP, of each wireless link between the plurality of stations and the AP by monitoring data transferred on each wireless link, wherein the AP is an 802.11 AP that is part of an 802.11 wireless local area network (WLAN);
- determining an available data rate of each wireless link;
- calculating a bandwidth headroom based on the actual data rate and the available data rate;
- calculating a plurality of assessment values for each wireless link over a period of time based on the actual data rate, a boundary constant, and the bandwidth headroom;
- normalizing the plurality of assessment values over the period of time;
- determining an indication of link quality for the AP based on the normalized plurality of assessment values;
- and
- sending the indication of the link quality to a service provider of the AP that resides outside of the WLAN of the AP.
An Access Point (AP) for evaluating a plurality of wireless links between a plurality of stations and the AP, wherein each station of the plurality of stations has one wireless link of the plurality of wireless links to the AP, the AP comprising a processor operatively coupled to a transceiver, the processor and transceiver configured to
- measure an actual data rate, exclusively from the AP, of each wireless link between the plurality of stations and the AP by monitoring data transferred on each wireless link, wherein the AP is an 802.11 AP that is part of an 802.11 wireless local area network (WLAN);
- determine an available data rate of each wireless link;
- calculate a bandwidth headroom based on the actual data rate and the available data rate;
- calculate a plurality of assessment values for each wireless link over a period of time based on the actual data rate, a boundary constant, and the bandwidth headroom;
- normalize the plurality of assessment values over the period of time;
- determine an indication of link quality for the AP based on the normalized plurality of assessment values;
- and
- send the indication of the link quality to a service provider of the AP that resides outside of the WLAN of the AP.
