Abstract
Some demonstrative embodiments include coordinating a session transfer between first and second multi-band wireless communication devices capable of communicating over at least first and second wireless communication frequency bands, wherein at least one device uses the same medium access control (MAC) address in both the first and second wireless communication frequency bands. An information element may be used to convey information between the devices to assist in the transfer.
