Patent ID: 8687512

Claim:
A method comprising: receiving, at a network device, a current request on a first communication band from a wireless client; determining, by the network device, whether to continue to use the first communication band or use a second communication band without switching to the second communication band subsequent to receiving the current request, wherein the determining operation comprises: tracking and storing, by the network device, a signal strength indicator value indicating a signal strength associated with a previous request received on the second communication band at the network device within a pre-determined time period prior to receiving the current request; and based at least on the signal strength indicator value associated with the previous request received on the second communication band before the current request was received on the first communication band, determining that the network device should continue to use the first communication band; responsive to determining that the network device should continue to use the first communication band, transmitting, from the network device, a response corresponding to the current request on the first communication band to the wireless client.
