Currently, the most popular telecommunications tools to solve the above problems are the technologies of the Ethernet and xDSL families. When using xDSL technology, the information transfer rate largely depends on the length and noise of the telephone line and ranges from 64 kbits to 24 Mbits. At 64 kbps, it is almost impossible to use multimedia resources - IP telephony, video conferences, streaming video and other similar services require higher speeds, starting from 1-2 Mbit, for normal operation.
