Broadband is a technology for transmitting data over a network, in which data is transmitted as modulated radio frequency signals.
As a rule, more than one signal is transmitted for which the carrier bandwidth is allocated in a special way. Broadband cable is usually shared by several networks or systems, such as television or video conferencing systems.
The term broadband is used to describe high-speed networks that allow signals of different services, such as data, voice and video, to be transmitted simultaneously.
Types of broadband
- Digital Subscriber Line. The user accesses the Internet via a telephone cable. DSL is a widely available technology that is gradually being supplanted by broadband connections – cable and fiber optics. DSL provides download speeds of 5 to 35 Mbit/s and upload speeds of 1 to 10 Mbit/s.
- Cable Internet. The provider uses coaxial cable, which is also used for television. It has low latency, download speed from 10 to 500 Mbit/s and upload speed from 5 to 50 Mbit/s.
- Fiber Optic Internet. Provides faster speeds than DSL or cable. Data download speed over fiber optic is from 250 to 1,000 Mbit / s and the transfer speed from 250 to 1,000 Mbit / s.
- Satellite Internet. It is carried out with the help of communication satellites. Ground stations transmit Internet data in the form of radio waves to satellites in low earth orbit. From the satellites, the data are sent to more distant ground stations. Satellite Internet is used in remote regions. The download speed is from 12 to 100 Mbit/s and the upload speed is 3 Mbit/s.
- Wireless broadband (Wi-Fi) connects users to the Internet using radio signals instead of cables. Speeds are generally comparable to DSL and cable modem.
