2 Global Evolution to 3G CDMA CDMA IS-95A IS-95B 3G: CDMA2000 Voice, 14.4k Voice, 64k 2x Voice, 153k/2400k, RF backward compatible TDMA Voice Leveraging ANSI-41 Core GSM1x 3G: EDGE k? GSM GPRS New Band Voice, 9.6k Data only, 10-50k 3G: UMTS (WCDMA) Voice, 64k/384k Source: Qualcomm PDC (Japan) New Band 3G: WCDMA (NTT) Voice, 9.6k Voice, 64k/384k April 17, 2002, Page 2

3 TDMA to 3G: Possible Migration Path TDMA TDMA Upgrade Network Adding to GSM Adding to EDGE GPRS WCDMA BTS MSC PSTN New Equipment New Equipment Software Upgrade (RLC/MAC) New Equipment Modem Pool * Usually co-located with TDMA & 2G/2.5G equipment, requires separate interface protocols GSM MSC* GSM BTS BTS* GSM/GPRS GSM BSC BSC* GSM/GPRS/ EDGE BSC* Software Update New Terminal (GAIT: GSM/TDMA?) New Terminal (GAIT/GPRS?) A-bis Interface** WCDMA BSC* New Equipment IP Backbone GSM/GPRS/ EDGE BTS* New Equipment WWW VPN Enterprise Network New Equipment Non-standard router New Terminal (TDMA/GSM/GPRS/ EDGE/AMPS?) SGSN GGSN WCDMA BTS* New Equipment 3G/GPRS GPRS Backbone 3G SGSN* New Terminal (TDMA/GSM/ GPRS/EDGE/ WCDMA/ AMPS?) New Equipment 3G GGSN* Upgrade New Equipment **New Interface required for higher speed GPRS rates or EDGE deployment (not deployed in most GPRS systems today) April 17, 2002, Page 3
