A Network device including a security module to establish, in response to the network device being capable of operating in multiple frequency bands, and in response to the network device operating in a first frequency band, security for the frequency band and a second frequency band by performing a single authentication in the first frequency band prior to the network device switching operation form the first frequency band to the second frequency band. A session transfer module to transfer, subsequent to the network device switching operation from the first frequency band to the second frequency band, a communication session of the network device from the first frequency band to the second frequency band. The communication session resumes in the second frequency band using the security established for the second frequency band during the operation of the network device in the first frequency band.
