Some demonstrative embodiments include coordinating a session transfer timeout period between first and second multi-band wireless communication devices capable of communicating over at least first and second wireless communication frequency bands, wherein the session transfer timeout period corresponds to at least one communication session between the first and second wireless communication devices; and if the first wireless communication unit cannot communicate with the second wireless communication device over the first wireless communication frequency band for a time period of at least the session transfer timeout period, transferring the at least one communication session from the first wireless communication frequency band to the second wireless communication frequency band. Other embodiments are described and claimed.
