History GSM GSM (Global System for Mobile Communication)
1 1982 "Group Special Mobile" is created within CEPT 2.1986 A Permanent Nucleus is set up 3.1987 Main radio transmission techniques are chosen, based on prototype evaluation (1986) 4.1989 GSM becomes an ETSI technical committee 5.1990 The phase 1 GSM900 specification (drafted 1987 - 1990 ) are frozen, DCS1800 adaptation start 6.1991 First system are running ( Telecom 91 exhibition,…) DCS1800 specification are frozen 7. 1992 All major European GSM900 operators begin commercial operations

Konfigurasi DualBand System Sistem dualband terpasang dengan mengopersikan atau menambahkan perangkat hardware cabinet BTS DCS 1800 pada sistem GSM 900 yang sudah ada.

GSM900 BTS
Jaringan yang bekerja pada GSM900 dan DCS 1800, dianggap sebagai suatu jaringan dengan PLMN tunggal.
Integrated GSM900/DCS1800 BTS

Implementasi jaringan dualband ini dapat diterapkan dalam beberapa kombinasi antara lain : 1. Satu BSC dengan satu jenis band 2. Satu BSC dengan dua jenis band 3.

Hardware DualBand Spesifikasi MSC DualBand : MSC dapat mendukung peralatan BSS dari vendor yang berbeda untuk setiap band frekuensi. Agar dualband mampu bekerja dengan baik, maka MSC perlu memiliki kemampuan untuk menangani elemen informasi classmark 3 (CM3 dikirim oleh MS dualband ke MSC berisi informasi kemampuan MS)
Spesifikasi MS Dualband &
Mekanisme Penanganan MS DualBand Dalam Jaringan: Suatu MS dapat beroperasi pada jaringan dualband dengan cara antara lain, MS hanya mendukung satu band atau MS dapat mendukung lebih dari satu band tapi hanya dapat berfungsi pada satu band
Mekanisme Dualband Mekanisme penanganan MS dualband tersebut dapat dijelaskan sebagai berikut : 1. MS akan dipegang oleh jaringan DCS 1800 layer pada dua kondisi idle mode dan dedicated mode selama tersedia kanal dalam cakupan radio DCS 1800 2. MS dapat ditangani membangun panggilan pada DCS 1800.
dan sel
3. MS yang berada pada layer GSM 900 dapat ditangani ke layer bawah (DCS 1800) jika memungkinkan. 4. MS yang berada pada layer DCS 1800 akan dipindahkan pemegangan kanalnya ke layer atas (GSM 900 ) jika hanya diperlukan.

What is GPRS ? • General Packet Radio Service, new technology on wireless data communication that offers mobile data communication service with a higher bit rate. • The next step from air interface evolution which for the first time ever based on PACKET SWITCH • “ Always-On” Connection
What can GPRS offer you ? • An “Always-On” Packet Switch Service • Maximum data speed up to 171,2 kbps • Offer high QoS for the users and low Cost for operators • Billing alternatives
DATA RATES REQUIRED FOR APPLICATIONS
