McCaw to study cellular phones as safety questions affect sales

Article Abstract:

McCaw Cellular Communications Chmn Craig McCaw is commissioning a study of the possible medical effects of users of the radio waves emitted by cellular telephone antennae. University of Utah professor Om Gandhi will perform a computer analysis of current tests of the medical effects of electromagnetic radiation in the cellular frequencies. McCaw's announcement follows a suit filed in Florida in which a widower claims that a cellular phone caused his wife's death by brain cancer. While no research links cellular phone use to cancer, several scientists say that the suit points up the lack of research on the physiological effects of electromagnetic fields, especially in the 800-MHz to 900-MHz range of cellular phones. Sanford Bernstein and Co analyst Gregory Sawers predicts a slowdown in cellular industry growth rates by 2nd or 3rd qtr 1993 if customers' concerns about cellular safety are not allayed.

Cellular phones dial digital for growth

Article Abstract:

Cellular-telephone businesses are looking to digital networks to cut costs, resolve conflicts with crowding on airwaves, and spur growth. Because cellular telephones have become so popular, there are areas in some cities or heavily traveled highways where calls can be blocked during certain times of the day because so many people are attempting to make calls. To prevent cellular gridlock, cellular operators in Los Angeles and New York City are installing digital systems. The systems are expected to begin operations early in 1991. The networks will be compatible with existing analog cellular phones will increase by 300 percent the number of calls that can be handled in the radio spectrum. Digital networks are also expected to reduce operating costs. Greater capacity and better built-in diagnostic capabilities will lower costs per channel by 10 to 25 percent.

Cellular industry group acts to avert crisis by research into phones' safety

Article Abstract:

The Cellular Telecommunications Industry Assn says it will fund research into the safety of cellular phones. The association says it will pay for a fast study of existing research into the physiological effects of radio waves generated by cellular telephones. The announcement comes on the heels of a week of immense publicity, after it was revealed that a Florida man had charged in a lawsuit that use of a cellular phone contributed to his wife's brain cancer. No scientific study conclusively links electromagnetic fields to cancer, but many scientists say that laboratory evidence suggests that some radio waves galvanize abnormal cell activity and reproduction. The medical concerns have driven down such cellular stocks such as Motorola Inc, McCaw Cellular Communications Inc, Pacific Telesis Group and Southwestern Bell Corp.
