- From the {New York Times} 11/18/92.
-
- Japan is experimenting with wireless telephones that are cheaper and
- possibly closer to availability than the latest versions under
- development in the United States, according to Japan's second-largest
- long-distance carrier.
-
- Dr. Sachio Semmoto, senior vice president with the DDI Corporation,
- said yesterday that his company was developing a new system called
- "personal handy phone." The Japanese phones may be commercially
- available as early as next year, he said. Equivalent United States
- phone systems called personal communications services may be three or
- more years away from market.
-
- Despite manufacturing most of America's cellular telephones, Japan has
- had until recently a fledgling domestic market for wireless telephone
- service. High service prices have discouraged all but the corporate
- customer. There are one million cellular subscribers in Japan
- compared with 10 million in the United States, which has a population
- double that of Japan.
-
- Japanese cellular phones, which can only be rented, cost the
- equivalent of $100 or more a month for access charges and $1.60 for
- three minutes of air time. By contrast, DDI's personal handy phones
- are expected to cost only $16.26 a month in access charges and 24
- cents for three minutes of air time.
-
- Personal handy phones would resemble American cordless telephones,
- which operate on different radio frequencies from cellular. The
- Japanese phones, however, would use the same frequencies contemplated
- for American personal communications services.
-
- The handy-phone network would cost only one-hundredth as much as a
- cellular network to build, and the prices for service would be sharply
- lower than that for cellular, Dr. Semmoto, who has a doctorate in
- electrical engineering, said.
-
- Cellular "base stations" of radio transmitting equipment that make
- cellular service possible cost as much as $3 million; stations for
- personal handy phones might cost as little as $30,000.
-
- Personal handy phones, designed to weigh about half the smallest
- cellular phones, could be used only within 1,000 feet of the base
- station and could not be operated in a car or on the street.
-
- But because of common technical standards, Japanese users could
- operate their handy phones from building to building. Base stations
- could be installed in homes, office buildings, supermarkets,
- department stores and other buildings.
-
- "Our concept is to attack the consumer market, rather than the
- business market," Dr. Semmoto said. "But our ultimate goal is for
- this technology to spread around the world, especially to the United
- States and Europe."
-
- Dr. Semmoto is visiting United States companies to discuss the
- technology so they might consider adopting it. He said he had met
- with regional Bell companies, cable-television companies and
- long-distance carriers like the MCI Communications Corporation, which
- recently proposed building a national network of small wireless
- phones.
