TECHNICAL DETAILS T E C H N I C A L D E TA I L S CDMA technology uses a feature called DSSS (Direct Sequence Spread Spectrum) that enables CDMA Standard Designator Description the phone to keep communication from being crossed and to use one frequency channel by multiple users in the same specific area. This results in a 10-fold capacity increase when compared with analog mode. In addition, features Basic Air Interface TIA/EIA-95A CDMA Dual-Mode Air Interface TSB-74 14.4kbps radio link protocol and ANSI J-STD-008 inter-band operations TIA/EIA-IS2000 IS-95 adapted for PCS frequency ANSI TIA/EIA 553A band cdma2000 1xRTT AirInterface Advanced Mobile Phone Service such as soft/ softer handoff, hard Handoff, and dynamic RF power control technologies combine to reduce call interruptions.
