Abstract
A brief overview of the Bell System's Advanced Mobile Phone Service (AMPS) is given. This is followed by a description of the mobile vehicular equipment now operating in the Chicago field trial of this AMPS system. The paper then considers the need for portables and their impact upon a cellular system designed to service vehicle-mounted mobiles. Finally, a discussion is given of portable circuitry and physical design required to minimize power consumption, weight and volume.Keywords
