1. General Introduction

The SCH-470 cellular phone functions as only digital cellular phone working in CDMA (Code Division

Multiple Access) mode. CDMA type digital mode applies DSSS (Direct Sequential Spread spectrum) mode

which first came to be used in the military.

The DSSS reduces channel cross talk and allow to use one frequency channel by multiple users in the same

specific area, resulting in increase of channel capacity to about ten times compared to that of analog mode

currently used.

Soft/Softer Handoff, Hard Handoff, and Dynamic RF Power Control technologies are combined into this

phone to reduce the call drop while usage.

CDMA digital cellular network consists of MSO (Mobile Switching Office), BSC (Base Station Controller),

BTS (Base Station Transmission System), and MS (Mobile Station). MS meets the specifications of the below:

¶UIS-95A : Mobile Station-Base Station Compatibility Standard for Dual-Mode Wideband Spread Spectrum

Cellular System

¶UIS-96A : Speech Service Option 1 Standard for Dual-Mode Wideband Spread Spectrum Cellular Systems

¶UIS-98A : Standards for Dual-Mode Wideband Spread Spectrum Cellular Mobile Station

¶UIS-126 : Mobile Station Loopback Service Options Standard

SCH-470 is composed of main handset, rapid charger, cradle, two batteries.
