  • 1. Teknologi Wireless dan Karakteristiknya TIK-2403 Jaringan Komputer (3 sks) Dosen: Ir. Sihar, MT. Program studi Teknik Informatika Bandung 2007
  • 2. Referensi: 1) 2) 3) __________Wireless Networking Basics. Netgear, Inc. 2005. Horak, R. Telecommunications and Data Communication. John Wiley & Sons. 2007. Wesolowski, K. Mobile Communication Systems. John Wiley & Sons. 2002.
  • 3. Jaringan wireless (nirkabel) adalah suatu jaringan komputer berbasiskan teknologi jaringan yang memanfaatkan gelombang elektromagnetik melalui udara sebagai media untuk mengirimkan informasi dari pengirim ke penerima. Wireless Fidelity (WiFi): IEEE 802.11;UHF/SHFradio; 2.4GHz dan 5.1GHz Beberapa Teknologi Wireless Bluetooth: IEEE 802.15;UHF-radio; 2.4GHz IrDA: IR-light; 300GHz-400THz VSAT: UHF/SHF/EHFradio; 1-40GHz WiMAX: IEEE 802.16;UHF-radio; 3.3GHz
  • 4. Outdoor: 50-200m Indoor: 1030m Skalabilita s Wireless Technolog y Long-range outdoor: 5Km20Km Mid-range outdoor: 200m4Km
  • 5. WiFi 802.11g Radio Frequency Channels
  • 6. Standar: IS-95 CDMA, GSM Tergolong generasi 2G: speech dan text Lebar kanal: 56Kbps Umumnya dalam skalabilitas: outdoor-range Standar: UMTS/WCDMA, CDMA2000 Tergolong generasi 3G: speech, text, image dan video Lebar kanal: 384Kbps Umumnya dalam skalabilitas: outdoor-range
  • 7. Standar: 802.15 Tergolong generasi Personal Area Network ; Pico-NET Lebar kanal: 1Mbps Umumnya dalam skalabilitas: indoor-range Standar: 802.11b Tergolong generasi Wireless Access Communication Network ; MANET Lebar kanal: 5-11Mbps Umumnya dalam skalabilitas: indoor-range, outdoor-range
  • 8. Standar: 802.11a/g Tergolong generasi Wireless Access Communication Network ; MANET Lebar kanal: 54Mbps Umumnya dalam skalabilitas: indoor-range, outdoor-range (optional) Standar: 802.11b Tergolong generasi Wireless Access Communication Network ; MANET Lebar kanal: 5-11Mbps Umumnya dalam skalabilitas: indoor-range, outdoor-range (optional)
  • 9. Mekanisme Menghindari collision: 1. Node Tx mengirimkan packet kecil RTS (request-to-send) ke basestation menggunakan CSMA (Carrier Sense Multiple Access) 2. Base-Station me-broadcast CTS (clear-to-send) untuk merespon RTS 3. RTS di-listening oleh semua node a. Node Tx mengirimkan data-frame b. Node lain menunda melakukan transmisi WS-5 WS-3 WS-1 B S WS-2 WS-4
