- *** AT&T today announced a high-power, all-digital cordless phone
- with four times the range of today's conventional cordless
- telephones. The AT&T Extended Range Cordless Telephone 9530
- operates in the 900-MHz frequency, providing virtually
- interference-free conversations with consistent sound quality up
- to one mile from the base. The AT&T 9530 uses full digital
- transmission to encode speech onto a radio signal, much like music
- is encoded onto a CD, and to provide clearer sound over a longer
- range than cordless phones operating in the 46/49-MHz frequency.
- AT&T's spread-spectrum, frequency-hopping architecture, which is
- patent-pending, actually avoids interference by "hopping" the
- radio signal among 50 of the available 173 channels during a
- conversation. If any of the channels experience interference, the
- 9530 automatically swaps it for a new, clearer channel. Because
- it operates over a different frequency, the AT&T 9530 is
- unaffected by forms of interference common to 46/49-MHz cordless
- phones, such as garage door openers, baby monitors and radio
- intercoms. It also performs well in environments typically
- difficult for conventional cordless, such as high-rise apartment
- and multilevel buildings. The random selection of 50 of 173
- channels, along with digital speech encoding, makes it nearly
- impossible to eavesdrop on conversations. The AT&T 9530 was
- designed and developed by AT&T Bell Laboratories, employing
- advanced integrated circuit technology developed jointly with AT&T
- Microelectronics. The AT&T Extended Range Cordless Telephone 9530
- will be available in late spring at AT&T Phone Centers nationwide
- for $449.99. For more information, call 800-222-3111.
