TIA TO PUBLISH CDMA DIGITAL CELLULAR TELEPHONE STANDARD

 WASHINGTON, July 16 /PRNewswire/ -- Allen R. "Mike" Frischkorn Jr., president of the Telecommunications Industry Association (TIA), today announced that TIA will publish a new voluntary industry standard for digital cellular telephone systems. The new standard, to be known as IS-95, was prepared by TIA's engineering subcommittee TR-45.5, chaired by Gerard Flynn of NYNEX. IS-95 was developed by the subcommittee from a submission made by California-based QUALCOMM, a proponent of the Code Division Multiple Access (CDMA) technology. Because of the rapid evolution of cellular technology, the work is being released as an interim standard. The interim designation allows more rapid updating of the standard as manufacturers and users gain practical experience with the design.
 This is the second digital cellular technology approved by TIA. In 1990, the group released an interim standard for Time Division Multiple Access (TDMA) technology. Both standards, which promise better spectrum efficiency than present analog systems, were prepared at the request of the Cellular Telecommunications Industry Association (CTIA), an organization of cellular system operators.
 "The availability of a second digital technology will provide system operators a choice of designs, as well as create a competitive marketplace," said Frischkorn. The duality of standards will not result in incompatibility, since both systems are designed to default to analog operation when digital channels are not available, he continued.
 The development and approval of the CDMA standard has been clouded by Interdigital's claim that it holds patents infringed upon by equipment conforming to the standard, for which it is not willing to grant royalty-free or royalty-bearing, non-discriminatory licenses as contemplated by TIA's patent policy. Consequently, the new CDMA interim standard bears a cautionary legend to that affect.
 TIA is a full-service trade organization with membership of more than 500, including large and small companies, which provide telecommunications materials, products, systems, distribution services and professional services to the United States and countries around the world. TIA represents the telecommunications industry in association with the Electronic Industries Association.
