IRIDIUM, INC. ANNOUNCES SYSTEM ENHANCEMENTS

 IRIDIUM, INC. ANNOUNCES SYSTEM ENHANCEMENTS
 WASHINGTON, Aug. 12 /PRNewswire/ -- Iridium, Inc. announced


enhancements to the planned Iridium system which are designed to improve significantly the performance of subscriber units operating in real world environments. As a result of these enhancements, individual satellites will cast 48 beams onto the surface of the earth, an increase of 11 beams per satellite over the original design. These enhancements are designed to enable the system to concentrate capacity where demand is most required, as well as reallocate channels in response to specific consumer demand for voice or paging services. In addition, the enhanced satellite beam pattern should reduce the potential for interference. The system enhancements have been designed by Motorola Satellite Communications to improve service to the pocket phone.
 Last week, Iridium, Inc. signed a contract with Motorola, Inc. (NYSE: MOT) for construction and delivery in orbit of the Iridium system for the commencement of commercial service in early 1998. The contract amount for the total system including the constellation and assorted control facilities is U.S. $3.37 billion.
 Robert W. Kinzie, chairman, Iridium, Inc., said, "We are extremely pleased with the results of our recent and continuing review of the technical characteristics of the Iridium system and the contract with Motorola Satellite Communications." He continued: "Our ultimate goal is to provide the customer with the highest quality global, wireless, hand-held communications services available, and we believe the enhanced Iridium system will accomplish that goal."
 The enhanced design should allow for dynamic reallocation of voice and paging services to accommodate respective market demand. The ability to reallocate capacity dynamically should allow the system to respond to regional market demand -- concentrating channels over densely populated regions. The enhanced Iridium system design has a greater number of total beams and will enable a reduction in size of the active constellation from 77 to 66 low earth orbit (LEO) satellites in six planes with 11 satellites in each plane.
 At the World Administrative Radio Conference (WARC '92), delegates from around the world allocated 1610 to 1626.5 MHz and 2483.5 to 2500 MHz frequency bandwidth on a global basis for land- mobile satellite services. The enhanced Iridium system proposes to utilize 10.5 MHz of spectrum between 1616 and 1626.5 MHz. The Federal Communications Commission (FCC) has awarded an experimental license to Motorola Satellite Communications for construction and launch of five Iridium satellites.
 Kinzie said, "Customers will be attracted to the service which provides superior quality at reasonable rates, and we believe that Iridium will be the service that will attract and retain subscribers and win in the marketplace."
 The Iridium system is a proposed global personal communications system which combines Motorola's space technology with its terrestrial wireless communications expertise. The Iridium system intends to offer high quality, global, voice, paging, facsimile, data and radiodetermination satellite services (RDSS) to its subscribers.
 Iridium, Inc. is an affiliate of Motorola, Inc., one of the world's leading providers of electronic equipment, systems and services for worldwide markets.
