Abstract
One feature provides a method for transmitting content to a receiving device, by establishing channel hopping sequence information with the receiving device via a first communication band. The channel hopping sequence information is associated with a plurality of traffic channels within a second communication band. Moreover, the method entails transmitting the content to the receiving device through the plurality of traffic channels via the second communication band using a channel hopping scheme implemented according to the channel hopping sequence information. In one embodiment, establishing the channel hopping sequence information with the receiving device via the first communication band further includes: obtaining a channel hopping sequence key; and transmitting the channel hopping sequence key to the receiving device within the first communication band.
