MULTIBAND OPERATION OF A SINGLE WI-FI RADIO
Multiband operation of a single Wi-Fi radio is described. Some examples can include operating a first radio frequency band on the single Wi-Fi radio of an access point. The method can include switching, based on client device traffic patterns, to a second radio frequency band on the single Wi-Fi radio of the access point.
1 . A method for multiband operation of a single Wi-Fi radio, the method comprising:
operating a first radio frequency band on the single Wi-Fi radio of an access point,
switching, based on client device traffic patterns, to a second radio frequency band on the single Wi-Fi radio of the access point.
2 . The method of claim 1 , wherein the first radio frequency band comprises a 2.4 Gigahertz radio frequency band and the second radio frequency band comprises a 5 Gigahertz radio frequency band.
3 . The method of claim 1 , comprising transmitting beacon packets on at least the first and second radio frequency bands in sequence from the single Wi-Fi radio of the access point.
4 . The method of claim 1 , wherein switching based on client device traffic patterns includes switching based on a traffic load on each radio frequency band.
5 . The method of claim 1 , wherein switching based on client device traffic patterns includes switching based on parameters of applications being supported by each radio frequency band.
6 . A non-transitory machine-readable medium storing a set of instructions that, when executed, cause a processing resource to:
operate a first radio frequency band on a single Wi-Fi radio of an access point; and
postpone a client device transmission over the first radio frequency band by modifying a network allocation vector of the client device before switching to a second radio frequency band on the single Wi-Fi radio of the access point.
7 . The medium of claim 6 , comprising instructions that, when executed, cause the processing resource to schedule switching between at least the first radio frequency band and the second radio frequency band based on traffic characteristics on each radio frequency band.
8 . The medium of claim 7 , wherein the traffic characteristics include a capability of the client device to utilize each radio frequency band.
9 . The medium of claim 7 , wherein the traffic characteristics include a sensitivity of an application to a delay.
10 . The medium of claim 6 , wherein modifying the network allocation vector of the client device includes distributing the network allocation vector by sending a Clear-To-Send-to-self frame.
11 . An access point, comprising:
a single Wi-Fi radio to:
operate a first radio frequency band;
operate a second radio frequency band; and
switch between the first radio frequency band and second radio frequency band based at least in part on airtime fairness or client device application delay sensitivity.
12 . The access point of claim 11 , wherein the single Wi-Fi radio to switch between the first radio frequency band and second radio frequency band based on airtime fairness includes the single Wi-Fi radio to schedule radio frequency band operation based on a transmission rate of the client device on each radio frequency band.
13 . The access point of claim 12 , wherein the single Wi-Fi radio to schedule radio frequency band operation based on a transmission rate of the client device on each radio frequency band includes the single Wi-Fi radio to schedule shorter operation on a radio frequency band with a high transmission rate client device.
14 . The access point of claim 11 , wherein the single Wi-Fi radio to switch between the first radio frequency band and second radio frequency band based on the client device application delay sensitivity includes the single Wi-Fi radio to schedule radio frequency band operation based on a type of an application utilized by a client device and a sensitivity of the application to a delay in transmission.
15 . The access point of claim 14 , wherein the single Wi-Fi radio to schedule radio frequency band operation based on a type of application utilized by the client device and the sensitivity of the application to the delay in transmission includes the single Wi-Fi radio to schedule maintaining an operation of a radio frequency band supporting a delay-sensitive client device application while the application is utilized.
16 . The access point of claim 14 , wherein the single Wi-Fi radio to schedule radio frequency band operation based on a type of application utilized by the client device and the sensitivity of the application to the delay in transmission includes the single Wi-Fi radio to schedule the switch between the first radio frequency band and the second radio frequency band to occur between transmissions of packets.
