MULTI-BAND WIRELESS STATION HAVING MULTIPLE RADIOS IN ONE BAND
First Claim
1. A method comprising:
- receiving, at a wireless station, a connection request from a first client station to connect to the wireless station, the wireless station operating in a multi-band frequency, the multi-band frequency including a first frequency band which is split into a first sub-band and a second sub-band, the first sub-band and the second sub-band being distinct frequency ranges within the first frequency band, the first client station communicating in the first frequency band;
determining, by the wireless station, whether to assign the first client station to the first sub-band or the second sub-band based on an assignment criteria, the assignment criteria being a function of at least one of a load of the wireless station at each of the first sub-band and the second sub-band, a first plurality of properties of the first frequency band and a second plurality of properties of the first client station; and
assigning, by the wireless station, the first client station to the first sub-band or the second sub-band based on the assignment criteria.

Abstract
The disclosure is related to a multi-band wireless station, e.g., a wireless access point, that includes more than one wireless radio in the same frequency band. The wireless station operates at multiple frequency bands, e.g., 2.4 GHz and 5 GHz. Further, the wireless station includes multiple radios in the same frequency band. For example, the wireless station can have two radios for the 5 GHz band—one for a low 5 GHz band and another for high 5 GHz band. If the client station is connecting to the 5 GHz band, it can either connect to the first sub-band or the second sub-band of the 5 GHz. The wireless station can decide the sub-band to which a particular client station has to be assigned based on a number of assignment attributes, e.g., client station attributes and the sub-band attributes.

16. A multi-band wireless station, comprising:
-
a plurality of wireless radios operating a plurality of frequency bands, wherein at least a first wireless radio and a second wireless radio operate at a first frequency band of the frequency bands, the first wireless radio operating at a first sub-band of the first frequency band, the second wireless radio operating at a second sub-band of the first frequency band; and a client station assignment module to assign a plurality of client stations requesting connection to the multi-band wireless station to the first frequency band, the client station assignment module to assign a first subset of the client stations to the first sub-band and a second subset of the client stations to the second sub-band based on an assignment criteria. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A computer-readable storage medium storing computer-executable instructions, comprising:
-
instructions for determining, at a multi-band wireless station to which a plurality of client stations have connected wirelessly, one or more of (a) a physical (PHY) link rate for each of the client stations, (b) a RSSI of each of the client, or (c) an available airtime at each of a first sub-band and a second sub-band at which the multi-band wireless station operates, the first sub-band and the second sub-band being distinct frequency ranges within a first frequency band of a plurality of frequency bands at which the multi-band wireless station operates; instructions for confirming that the PHY link rate or the RSSI of a specified client station of the client stations assigned to the first sub-band is below a first specified threshold; instructions for confirming that the PHY link rate or the RSSI of the specified client station exceeds the first specified threshold on the second sub-band; instructions for confirming that the available airtime at the second sub-band exceeds a second specified threshold; and instructions for disassociating the specified client station from the first sub-band and assigning the specified client station to the second sub-band. - View Dependent Claims (27)
