GH68-60756A 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), handsfree kit, and travel charger. Hands-Free Kit is designed to be operated in half-duplex mode taking turnaround delay between the phone and the system into account.
