The race to develop the pocket telephone

Article Abstract:

Personal communications networks may compete with existing cellular radio systems since they will be far less expensive, offer small, pocket-sized phones, use many more transmitters, operate at lower power and use higher frequencies. Personal communication networks do not have the range of cellular radio but will allow more users in a vicinity than the 832 limit of cellular radio. The signals emitting from personal communication networks cannot go around walls and floors of buildings, but this limitation allows the same frequency to be used by different users on different floors without interference. The Federal Communications Commission (FCC) has granted a license to Millicom Inc to field test the network in Orlando and Houston; other licenses for other companies are currently pending.

A phone in your pocket? Tryout set for new service

Article Abstract:

The Federal Communications Commission (FCC) has awarded a two-year license to Millicom Inc to develop an innovative phone network that uses hand-size cordless telephones. Such a wireless system, which is called a personal communications network, is seen as an alternative to existing cellular systems and to local telephone networks. Personal communications networks use high microwave frequencies and have a short range. Such networks, which rely on many low-powered transmitters, increase channels from the 832 available on current cellular systems to many hundreds. Millicom will spend $20 million to build a 25,000-subscriber system in Houston, TX, and a 20,000-subscriber system in Orlando, FL. Both systems are scheduled to go into service within two years.

Innovation hurts cellular stocks

Article Abstract:

The Federal Communications Commission's (FCC) recent licensing grant to Millicom Inc that allows it to develop a personal communications network caused stocks of cellular radio companies to fall on May 10, 1990. Millicom stock rose $1.25 on May 9, 1990, $1 on May 10, 1990 and closed at $20.50. McCaw Communications Inc's stock fell 25 cents on May 10, 1990, and was unchanged on May 10, 1990 to close at $23.50; McCaw's high in 1989 was $47.25. The personal communications network being developed by Millicom will use more transmitters operating at higher frequencies and lower power. The system will include wallet-sized handsets and make more channels available than cellular radio while offering comparable prices.
