Broadband Internet is the general name for a whole group of modern high-speed technologies for accessing the World Wide Web in constant mode. Data is received and transmitted at the same high speed, up to hundreds of Mbps. Thanks to the globalization of the broadband Internet market, prices and fiber and mobile offers for users they have been democratized and have access to digital television services; IP telephony; cloud storage capacity and much more. Internet service providers offer various types of broadband Internet connection. All available varieties can be roughly divided into two large groups:
permanent: based on cable connections;
optical fiber: through optical communication lines;
mobile: through wireless communication channels.
Rented line broadband
Early broadband technologies were based on Internet access via a digital leased line (DSL). Modern methods of digital signal processing can significantly increase telephone line capacity, which has made the xDSL family of technologies one of the most widespread in the world. The symbol "x" is used to denote the entire family of leased line access technologies, which differ in data rate and line multiplexing. They are designated by separate abbreviations: ADSL, HDSL, RADSL, SHDSL, VDSL. In general, all xDSL technologies can be divided into two categories: symmetrical - with the same data transmission and reception speed; asymmetric - with a higher speed of receiving data from the network. Symmetric technologies are most often used in the business sector, asymmetric - for subscriber access.
Access channels to the high-speed fiber optic network
Optical Internet access is the most widespread and fastest version of broadband access, widely used in apartment buildings. Each entrance to the house is connected via a switch via fiber optics to the provider, and a twisted pair cable is pulled to the end subscribers to connect to a router or directly to a computer network card. In this case, the speed of access to the global network will not exceed 100 Mbps. The highest speed connection is achieved when the subscriber is also connected via fiber optic cable, and not the usual copper twisted pair. Fiber optic access allows you to provide a connection speed of up to 1 Gbit / s, which allows you to connect any type of service: Internet, digital TV, IP telephony.
Fiber and mobile broadband
Broadband Internet access through the mobile networks of 3G and 4G mobile operators is a demanded service due to the large coverage area and the explosive proliferation of mobile devices. Today, 3G technology is already morally outdated, but it is widely used, since it is available in a significant part of the coverage of major operators. 4G technology is being actively introduced to replace 3G, allowing to develop much higher speed. In megalopolises and large cities, providers are also developing the provision of an Internet connection via WiMax, since most devices come with an already integrated WiFi module.
