A method includes establishing a secure connection between a client device and a first security gateway, the first security gateway being associated with a service provider for providing a service to the client device, and handing off the secure connection from the first security gateway to a second security gateway. In a preferred embodiment of the invention, digital RF samples are stored in a queue which is accessed by a searcher and demodulator. An existing reference voltage on the output side of the mirror can be used or a reference voltage can be created to be used for the voltage regulation of the reference side of the current mirror. The regulator is further formed with thick-wall portions for closing the exhaust holes. The device further includes one or more antennas coupled to the wireless communication module for transmitting and receiving data packets to and from a host system.
