Types of Broadband

THERE ARE 4 TYPES OF BROADBAND THAT IS:

  - DIGITAL SUBSCRIBES LINE (DSL)

 The following are The Subscribar Line (DSL):

1. 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.
2. Symmetrical Digital Subscriber Line (SDSL) – Used typically by businesses for services such as video conferencing, which need significant bandwidth both upstream and downstream

S        Fastes form of DSL typically available to business include:

• High data rate Digital Subscriber Line (HDSL); and
• Very High data rate Digital Subscriber Line (VDSL).

   - CABLE MODEM

•       Cable modem service enables cable operators to provide broadband using the same coaxial cables that deliver pictures and sound to your TV set.    
•       Most cable modems are external devices that have two connections, one to the cable wall outlet, the other to a computer. They provide transmission speeds of 1.5 Mbps or more.

   - FIBRE OPTIC

•      Fiber optic technology converts electrical signals carrying data to light and sends the light through transparent glass fibers about the diameter of a human hair. Fiber transmits data at speeds far exceeding current DSL or cable modem speeds, typically by tens or even hundreds of Mbps.
•      The actual speed you experience will vary depending on a variety of factors, such as how close to your computer the service provider brings the fiber and how the service provider configures the service, including the amount of bandwidth used. The same fiber providing your broadband can also simultaneously deliver voice (VoIP) and videoservices, including video-on-demand.
•      Telecommunications providers sometimes offer fiber broadband in limited areas and have announced plans to expand their fiber networks and offer bundled voice, Internet access, and video services
•      Variations of the technology run the fiber all the way to the customer’s home or business, to the curb outside, or to a location somewhere between the provider’s facilities and the customer

   

    
      - SATELLITE

•        Just as satellites orbiting the earth provide necessary links for telephone and television service, they can also provide links for broadband. Satellite broadband is another form of wireless broadband, and is also useful for serving remote or sparsely populated areas.
•              Downstream and upstream speeds for satellite broadband depend on several factors, including the provider and service package purchased, the consumer’s line of sight to the orbiting satellite, and the weather. Typically a consumer can expect to receive (download) at a speed of about 500 Kbps and send (upload) at a speed of about 80 Kbps. These speeds may be slower than DSL and cable modem, but they are about 10 times faster than the download speed with dial-up Internet access. Service can be disrupted in extreme weather conditions.
