May 21, 1998 Iridium demonstrates satellite call SCOTTSDALE, Ariz.-Iridium L.L.C.'s satellite communications system using digital wireless technology developed by Motorola Inc. was demonstrated with phone calls placed on the system Wednesday night, following the completion of the satellite-launching phase of the network earlier this week. Nearly 150 service providers and Iridium gateway owners and operators from 17 countries took part in the 30-minute call demonstration, which included one call lasting 15 minutes that also successfully executed a satellite-to-satellite handoff, said Motorola. Durrell Hillis, senior vice president and general manager of Motorola's Space and Systems Technology Group based in Scottsdale, Ariz., placed the initial call from a product conference at a hotel there to Robert Kinzie, chairman of the board for Iridium L.L.C., who was in Geneva. Hillis placed the call on an Iridium handset, which communicated with an orbiting Iridium satellite, then routed the call to the Iridium North America Gateway in Tempe, Ariz., which routed the call to the public switched telephone network. The call then was routed to a call bridge in New York via US West Inc. so that all conference participants could listen to the call, Motorola explained. Nearly a dozen of the conference participants were given the opportunity to place calls on the Iridium system to each other, or to people in other countries. Motorola described the sound quality as excellent. More than 30 separate phone calls totaling 120 call minutes were completed on the satellite system that transmitted conversations in several languages, including Japanese Hindi, Russian and Spanish, said Motorola.
