A transmitting antenna which is mounted in the interior of a door mirror of a vehicle and radiates transmitted waves through the surface of said door mirror, and a receiving antenna that receives reflective waves from an object existing near the vehicle through the surface of said door mirror are rotated by a drive portion equipped within the door mirror. The system comprises a tandem adapted for insertion into a cervix of a patient. The communication device begins a connection setup for one or more wireless communication devices, obtains MIMO and DC HSDPA capabilities for the one or more wireless communication devices and optimizes the coexistence of MIMO and DC HSDPA.
