3G BROADBAND WIRELESS SYSTEMS
Cellular Generasi 2 menyediakan perbaikan pada kualitas voice (suara), kapasitas voice dan mulai support untuk data.
Dengan paradigma berbasis circuit-switched membuat generasi 2 ini punya keterbatasan dalam penyediaan data kecepatan tinggi.
Cellular Generasi 3 menyediakan layanan data kecepatan tinggi, menaikkan kapasitas voice, support layanan advance, seperti multi media.
ITU mengenalkan proposal 3G(dikenal sebagai IMT-2000) dengan tujuan untuk menciptakan spesifikasi komunikasi mobile yang global yang bisa memfasilitasi interoperability global dengan biaya rendah.
VISI 3G
Universal global roaming Multimedia (voice, data dan video) Menaikkan kecepatan data :
2 Mbps saat stasioner pada lokasi tertentu 384 kbps saat bergerak
Menaikkan kapasitas (spektral tertentu) IP architecture

STANDARISASI INTERNASIONALYANG MENDUKUNG 3G
1. ITU (International Telecommunication Union) Standard radio dan spektrum
2. IMT-2000 (International Mobile Tlecommunication-2000) Nama payung dari 3G
3. 3G Partnership Project (3GPP) Fokus pada evolusi dari core network dan akses
4. Standard body nasional yang berkolaborasi dengan 3GPP: ARIB, TIA, TTA, TTC, CWTS, T1, ETSI
3GPP Stands for 3rd Generation Partnership Project
DRAWBACK OF 1G
1G Wireless System

1G TECHNOLOGY
1G refers to the first generation of wireless telephone technology, mobile telecommunications which was first introduced in 1980s and completed in early 1990s.
it's Speed was upto 2.4kbps.
1G network use Analog Signal.
AMPS was first launched in USA in 1G mobile systems.
2G TECHNOLOGY
1. 2G technology refers to the 2nd generation which is based on GSM.
2. It was launched in Finland in the year 1991.
3. 2G network use digital signals.
4. Its data speed was upto 64kbps.
It enables services such as text messages, picture messages and MMS (multi media message).
It provides better quality and capacity .
2G TECHNOLOGY
2G requires strong digital signals to help mobile phones work. If there is no network coverage in any specific area , digital signals would weak.
These systems are unable to handle complex data such as Videos
