GSM ke GPRS) • Layanan data yang lebih maju (mis. WAP, ring tone, logo) • Arsitektur radio berubah utk menghandle peningkatan bandwidth • “Human Machine Interface” mulai berubah (mis. PDA) • Color display • Bluetooth dan Wireless LAN 3G • Standar IMT-2000 • Kecepatan data 144 Kbps sampai 2 Mbps • Multimedia messaging • MPEG-4 Video • Akses internet kecepatan tinggi ITU vision of IMT-2000 world Perkembangan GSM GSM TD-CDMA GPRS EDGE WCDMA 2G 2,5 G 3G • GSM(Global System for Mobile Communication) is the most widely adopted mobile standard in the world. • GPRS(General Packet Radio Service) allows large amounts of data to be sent over mobile networks at speed 3 to 4 times greater than conventional GSM systems. • EDGE(Enhanced Data Rates for Global Evolution) is a 3G technology that delivers broadband-like data speed to mobile devices. • TD-CDMA (Time Division-Code Division Multiple Access), mixture of TDMA and CDMA provides better QoS for multimedia communications in terms of data throughput and voice/video quality • WCDMA(Wideband Code Division Multiple Access), the world’s leading 3G technology
