Embodiment Construction

[0025] Referring now to the drawings, there is shown a mobile telephone system, generally designated by the numeral 10, of the present invention. The present mobile telephone system 10 is particularly suitable for use in a vehicle. The mobile telephone system 10 is distributed over a number of separate and distinct physical units located at various locations within the vehicle. Separate physical units communicate with each other via local wireless communication paths. The preferred embodiment of the invention comprises two physical units: a base unit 20 and a control unit 40 . The base unit 20 includes a fully functional transceiver capable of sending and receiving radio signals to and from a station located outside the vehicle. The control unit 40 includes the interface components required for the user to control the transceiver. In a preferred embodiment of the invention, the base unit 20 is housed in the cabin or dashboard of the vehicle, or under the seat of the vehicle...

Abstract

A radio-telephone includes a base unit mounted within the vehicle having a wide area transceiver for communicating with a station outside the vehicle, a control unit disposed in the vehicle remotely from the base unit, and a local area network for establishing a communication link between the base unit and the control unit. The local area network is adapted to transmit control and data signals between the base unit and the control unit. The control unit includes a keypad for entering commands and data that are transmitted to the base unit via the local area network, and a display for displaying information to the user. The control unit may also include a speaker and microphone. Alternatively, the speaker and microphone may be contained in a remote audio unit that is linked to the base unit via the local area network. The control unit may, for example, be incorporated into the steering wheel of a vehicle while the base unit is concealed in the trunk or under the seat of the vehicle.

Description

field of invention [0001] This invention relates generally to mobile radiotelephones and, more particularly, to a distributed mobile radiotelephone for use in vehicles. Background of the invention [0002] Currently, there are three generally accepted methods of providing cellular telephone service to the driver of a vehicle. First, a standard, hand-held cellular phone may be used by the driver, power for the hand-held cell phone may be provided by the hand-held unit's own battery pack, or by an adapter that plugs into the vehicle's cigarette lighter. Second, a standard hand-held cellular telephone can be held by a cradle mounted inside the vehicle. The stand can include an external speaker and microphone, allowing hands-free operation once the call is established. Third, the vehicle may have a built-in cellular telephone permanently affixed to the vehicle. [0003] Each of the above-mentioned solutions presents an undesirable trade-off between var...
