Broadband Connections: What Are They and How Do They Work?

best unifi broadband plan in malaysia

Broadband is a phrase used to describe high-speed Internet connectivity that is always available and faster than traditional dial-up access. A variety of factors will influence which broadband technology you choose. These factors could include your location (urban or rural), how broadband Internet connection is combined with additional services (such as voice telephone and home entertainment), cost, and availability. Besides, JomApply has the best Unifi broadband plan in Malaysia.

In this article, we will be discussing Digital Subscriber Line (DSL), Cable Modem, Fiber, and Satellite.

Digital Subscriber Line (DSL)

DSL is a wireline transmission technology that allows data to be sent more quickly over existing copper telephone lines in households and businesses. Transmission speeds range from a few hundred Kbps to millions of bits per second with DSL-based broadband (Mbps). The distance between your house or business and the closest telephone provider facility may affect the availability and speed of your DSL connection. DSL transmission technology can be classified as follows:

  • ADSL (Asymmetrical Digital Subscriber Line) – Asymmetrical Digital Subscriber Line (ADSL) is generally used by household customers, such as Internet surfers, who receive a lot of data but don’t spend much. The downstream direction of ADSL is often faster than the upstream direction. ADSL enables quicker downstream data transmission over the same line that is used for voice service, without interfering with conventional phone calls.
  • SDSL (Symmetrical Digital Subscriber Line) – Typically used by enterprises for video conferencing and other services that require a lot of bandwidth both upstream and downstream.

Cable Modem

Cable modem service allows cable companies to transmit broadband through the same coaxial lines that deliver video and audio to your television.

The majority of cable modems are external devices with two connections: one to a cable outlet and the other to a PC. They offer 1.5 Mbps or higher transmission speeds.

Subscribers can use their cable modem connection without dialling up an ISP by simply turning on their PCs. While utilising it, you can still watch cable television. The type of cable modem, cable network, and traffic load all influence transmission speeds. The speeds are comparable to those of DSL.


  • Fiber optic technology turns data-carrying electrical signals into light, which is then transmitted through clear glass fibres with a diameter of about a human hair. Fiber transfers data at speeds that are tens or even hundreds of times faster than existing DSL or cable modem speeds.
  • The speed you get depends on a number of things, including how close the service provider connects the fibre to your computer and how the service provider configures the service, including the quantity of bandwidth used. The same fibre that delivers your broadband can also supply talk (VoIP) and video services, including video-on-demand, at the same time.
  • Fiber broadband is sometimes available in restricted places, and telecommunications companies have announced intentions to expand their fibre networks and offer combined voice, Internet, and video services.
  • The fibre can be run all the way to the customer’s home or company, to the curb outside, or to a position halfway between the provider’s facilities and the customer, depending on the technology used.


Satellites circling the earth can provide broadband communications in the same way that they do for telephone and television services. Another type of wireless broadband is satellite broadband, which is excellent for supplying remote or sparsely inhabited areas.

The provider and service package bought, the consumer’s line of sight to the circling satellite, and the weather are all factors that affect satellite broadband downstream and upstream speeds. A consumer can typically anticipate receiving (download) at around 500 Kbps and send (upload) at around 80 Kbps. Although these speeds are slower than DSL and cable modem, they are nearly ten times faster than dial-up Internet access download speeds. In extreme weather conditions, service may be disrupted.
