1. General Introduction
The SCH-210 cellular phone functions as both analog cellular phone working in AMPS (Advanced Mobile
Phone Service) mode and 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:
IS-95A : Mobile Station-Base Station Compatibility Standard for Dual-Mode Wideband Spread Spectrum
Cellular System
IS-96A : Speech Service Option 1 Standard for Dual-Mode Wideband Spread Spectrum Cellular Systems
IS-98A : Standards for Dual-Mode Wideband Spread Spectrum Cellular Mobile Station
IS-126 : Mobile Station Loopback Service Options Standard
SCH-210 is composed of main handset, rapid charger, cradle, two batteries (1300 mAh, 850 mAh), hands-
free kit, and travel charger. Hands-Free Kit is designed to be operated in half-duplex mode taking turn-
around delay between the phone and the system into account.
