Evolusi Mobile Communication

• Analog• Hanya

layanan suara (voice)

• Beralih ke digital

• Layanan utama masih voice

• Layanan SMS

• Utk sambungan komputer dg modem, kecepatan rendah (7-14 Kbps)

• Teknologi antara (2G ke 3G)

• Perubahan thd arsitektur 2G (mis. GSM ke GPRS)

• Layanan data yang lebih maju (mis. WAP, ring tone, logo)

• Arsitektur radio berubah utk meng-handle peningkatan bandwidth

• “Human Machine Interface” mulai berubah (mis. PDA)

• Color display• Bluetooth dan

Wireless LAN

• Standar IMT-2000

• Kecepatan data 144 Kbps sampai 2 Mbps

• Multimedia messaging

• MPEG-4 Video• Akses internet

Perkembangan GSM

• 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
