Abstract

The RF Data Receiver is designed to provide a mobile computer user the capability of receiving large alphanumeric messages, such as E-mail, and small data files over the air. Such a receiver, capable of being car- ried comfortably on one's person, generally has the prob- lem of limited antenna aperture and power source capacity. Lap top and transportable computers have size and weight characteristics that make them too large to carry comfortably on the person also. When these prod- ucts are installed in a motor vehicle some of these issues can be overcome with only limited loss of mobility.

RF DATA RECEIVER AUTOMOTIVE APPLICATION

by Greg Fuller and Darrell Pfeffer

  The RF Data Receiver is designed to provide a mobile computer user the capability of receiving large alphanumeric messages, such as E-mail, and small data files over the air. Such a receiver, capable of being car- ried comfortably on one's person, generally has the prob- lem of limited antenna aperture and power source capacity. Lap top and transportable computers have size and weight characteristics that make them too large to carry comfortably on the person also. When these prod- ucts are installed in a motor vehicle some of these issues can be overcome with only limited loss of mobility.

  The capacity of a portable, laptop, transportable or palm top computer can be expanded when traveling in an automobile or truck by adding additional resources contained in or attached to the vehicle to improve the performance of the data receiver. Devices that can be powered by and installed in a vehicle include a fax machine, a larger more powerful computer, a video dis- play terminal, printer, and/or an RF transmitter. Addi- tionally, a larger more efficient antenna could be interfaced to the data receiver to further enhance the performance of the product.

  A typical installation of the RF Data Receiver in a vehicle is presented in Figure 1. The installation of the data receiver is coupled to an existing radio car radio or cellular phone...
