3 SISKOMBER-MODUL:01 Klasifikasi WIRELESS

4 SISKOMBER-MODUL:01 Ada sedikitnya satu terminal bergerak di dalam komunikasi Daya pancar tinggi Antena setinggi-tingginya Cakupan sel sebesar-besarnya Konsep Handoff tidak ada Pada awalnya Sistem Komunikasi Bergerak Syarat

5 SISKOMBER-MODUL:01 Generasi Awal Sistem Komunikasi Bergerak Kelemahan Biaya mahal karena perlu penguat daya tinggi dan antena tinggi Kenyamanan pelanggan terganggu saat berpindah cakupan Kapasitas rendah Efisiensi spektrum rendah

6 SISKOMBER-MODUL:01 Perkembangan Siskomber Sistem Komunikasi bergerak Terestrial Satelit  Siskomber Selluler  GMPCS (Global Mobile Personal Communication System)  Iridium,Globalstar

7 SISKOMBER-MODUL:01 Klasifikasi Sistem Cellular Menurut Daerah Jangkauan (Coverage) 1. Large Zone (Single Cell/Convensional). * Radius +/- 20 miles. * STKB – Inti. 2. Multi Zone (Cellular). * STB ( NMT, GSM, CDMA. 3. Global System (Mobile Satelite). * Iridium, Globalstar,GMPCS Menurut Sistem Transmisi yang digunakan 1. STB dgn Transmisi Tereterial. * Radio Teresterial (VHF/UHF). * Single Cell Convensional & Cellular. 2. STB dgn Transmisi Satelite. * Iridium, Globalstar, GMPCS

8 SISKOMBER-MODUL:01 Standar Sistem Seluler Sistem Seluler Analog – Generasi Pertama  AMPS ( Advanced Mobile Phone System )  NMT 450 ( Nordic Mobile Phone )  TACS ( Total Access Communication System ) Sistem Seluler Digital – Generasi Kedua  GSM ( Global System for Mobile Communication )  DAMPS ( Digital AMPS )  CDMA/IS-95 Generasi Ketiga  IMT 2000

9 SISKOMBER-MODUL:01 Technology Cellular. 1G wireless 2G wireless CDMA (Code Division Multiple Access) TDMA (Time Division Multiple Access) GSM (Global System for Mobile Communications) PDC (Personal Digital Cellular) AMPS (Advanced Mobile Phone Service) 3G wireless W-CDMA (Wide-band Code Division Multiple Access) CDMA Analog voice service - No data service - Digital voice service - 9.6K to 14.4K bit/sec. - CDMA, TDMA and PDC offer one-way data transmissions only - Enhanced calling features like caller ID - No always-on data connection - Superior voice quality - Up to 2M bit/sec. - always-on data - Broadband data services like video & multimedia - Enhanced roaming

10 SISKOMBER-MODUL:01 Cellular Evolution : European ways TACS, NMT, etc GSM GPRS & EDGE IMT-2000/ UMTS 1G 2G2.5G3G Analog speech Digial speech, low speed data Digial speech, low speed data, medium speed up to 384 kbs 4 QoS Class : Conversational, streaming, interactive, & background

11 SISKOMBER-MODUL:01 2G Vs 3G

12 SISKOMBER-MODUL:01 Advanced Mobile Phone Service. Pioneer of cellular telecommunications FDMA-based analog system –Low capacity of subscriber per cell Unsecure –Phone number can be scanned and copied –Voice conversation is not encrypted

13 SISKOMBER-MODUL:01 Global System for Mobile Communications. The most popular of cellular technologies –Supported in nearly all countries TDMA-based digital system –8 times capacity of AMPS per frequency band Secure –All information exchange between Mobile Station (MS) and Base Station (BS) are encrypted

14 SISKOMBER-MODUL:01 Cellular System Architecture.

15 SISKOMBER-MODUL:01 CDMAOne. Newest cellular phone standard –Developed by Qualcomm –Supported mainly in the Americas and East Asia CDMA-based digital system –Up to 18 times capacity of AMPS per frequency band Very Secure –Listeners need the right descrambler key –Optional encryption is also available
