Welcome Welcome CDMA technology uses a feature called CDMA DSSS (Direct Sequence Spread Spectrum) Standard that enables the phone to keep communication from being crossed and to Basic Air use one frequency channel by multiple Interface users in the same specific area. This results in a 10-fold capacity increase when compared with analog mode. In addition, features such as soft / softer handoff, hard handoff, and dynamic RF power control technologies combine to reduce call Network interruptions. The Cellular and PCS CDMA networks consist of MSO (Mobile Switching Office), BSC (Base Station Controller), BTS (Base Station Transmission System), and MS (Mobile Station). The following table lists some major CDMA standards.
