~Broadband Technology~* Definition
- a networking technologi
- user => Large part of the electro magnetic spectrum
- Higher throughput rates than best band
- Ussually employ frequency/time division multiplesing
- Allow multiple, independent communication to proced simultaneously over a singel underlying medium
* Fixed Line Technologies
- Digital subscriber Line ( DSL )
- Cable modem & cable TV - Hybird Fiber Coax ( HFC )
- Fixer to the home / Cwrb ( FTT/TTC )
- Broadband over powerline ( BPL )
* Wireless Technologies
1. Line Of Sight ( LOS ) => 2 titik yang melakukan komunikasi tanpa halangan
- Microwaves Links
- LMDS ( Local Multiprint Distribution Service )
- FSO ( Free Space Optics )
- Satellite
2. Non LOS ( N Los )
- MMDS
- GSM ( Global System for Mobile Communication )
- CDMA ( Code Division Multiple Access )
- 3 G ( Thrid general mobile Network )
- W Max ( Worldwide interoperability for microwave access )
* Highlight
- DSL
- Cable Modem & cable TV - Hybird Cyber Coax ( FTT / TTC )
- WMax
* Digital Subscriber Line (DSL)
- over traditional copper telephone lines, plain old telephones system (POTS) that already installed to homes and businesses
- transmission speeds ranging from several hundred (Kbps) to millions of bits per second (Mbps)
- the availability and speed may depend on the distance from home or business to the closest telephone company facility
- xDSL:
- Asymmetrical Digital Subscriber Line (ADSL) – used primarily by residential customers, such as Internet surfers, who receive a lot of data but do not send much. ADSL typically provides faster speed in the downstream direction than the upstream direction. ADSL allows faster downstream data transmission over the same line used to provide voice service, without disrupting regular telephone calls on that line.
- Symmetrical Digital Subscriber Line (SDSL) – used typically by businesses for services such as video conferencing, which need significant bandwidth both upstream and downstream.
- High-data-rate Digital Subscriber Line (HDSL); and
- Very High-data-rate Digital Subscriber Line (VDSL).
* Cable Modem & Cable TV – Hybrid Fiber Coax (HFC)
- Cable modem service enables cable operators to provide broadband using the same coaxial cables that deliver pictures and sound to TV set.
- Most cable modems are external devices that have two connections, one to the cable wall outlet and the other to a computer. They provide transmission speeds of 1.5 Mbps or more.
- Subscribers can access their cable modem service simply by turning on their computers without dialing-up an ISP and can still watch cable TV while using it.
- Transmission speeds vary depending on the type of cable modem, cable network, and traffic load. Speeds are comparable to DSL.
* WiMax
-WiFi type connectivity over a much greater range wireless access solution
- LOS WiMax: point to point, NLOS WiMax: point to multipoint
- IEEE 802.16 standard
- Fixed, Nomadic, Portable, Mobile
- Radius 3 to 90 km, 75 Mbps per channel for fixed and portable access
- Up to 3 km and 15 Mbps for mobile network
