Looking for a suitable internet connection but confused by the plan options?

Fixed-network connections come in two basic technology types: wireless connections and cable connections. Cable is rather complicated to divide further, but let us dive in.
Optical fibres – the best of the best
Optical fibres are the cutting-edge technology in cable connections. Thanks to their ability to carry huge volumes of data over long distances, they are widely used on the backbone routes of internet service providers. However, their spread into households is limited mainly by cost, and they are expected to remain unavailable to most people for the coming decades.
DSL technology – connection over a landline copper cable
DSL technology, based on the original analogue telephone networks, brought gradual development in the form of dial-up modems, ISDN2 and then DSL technologies. Today's variants, such as ADSL and VDSL2, allow download speeds of up to 100 megabits per second. However, the copper network suffers from limited upload speed and in many places requires further infrastructure modifications. You can find our xDSL offer on the page https://uvtnet.cz/en/internet/
Coaxial cables – home wiring and cable TV
Coaxial cables, originally used for cable TV networks, thanks to the development of the DOCSIS 3.0 standard reach theoretical speeds of hundreds of megabits per second. However, their efficiency depends on the quality of the cable and its distance from the exchange, and, just as with copper cables, limited upload speed is a problem here too.
Wireless connection – where the cable does not reach
Wireless connections for fixed networks have made enormous progress in recent decades, enabling data transfer of up to hundreds of megabits per second. However, a shared spectrum can reduce transmission capacity when the network is overloaded. A well-designed network, though, remains stable in various weather conditions, and the choice of connection technology depends above all on the user's needs and the location of the connection.
