Promising areas of modernization of Internet networks

Digital data transfer – the process of transferring signals from point to point. To ensure such a process, copper wires, fiber-optic lines or wireless channels are used. The difference between digital and analog transmission is that the signals are sent in a continuous stream, forming waves or a sequence of pulses with a certain modulation. Modem equipment is used to send and receive such signals.

Data transfer methods

Nowadays there are mainly 2 methods of information transmission: serial and parallel. Serial is when symbols and other forms of information are encoded into bits and sent one after the other using wire, optical fiber, or frequency. The advantages of this method: processing is fast due to the ease of transmitting the bit of the digit, its parity. Signal speed is higher.

With the parallel method, the channel capacity is higher due to the division of the stream into several channels. This method is used inside the computer. For this, it is equipped with tires. The transmission speed is also high, but there is a nuance in the form of unevenness in the bit rate due to the fact that the wires differ in their characteristics. Therefore, the integrity of messages may be damaged.

During transmission, information flows from node to node until it reaches the end point of reception. This process is called switching. It has several principles of operation: packet or circuit switched. In the first case, the message is sent in independent blocks, and in the second, a special channel is used to continuously feed information.

Power Grid: Prospects for Data Transmission

Developers are interested in using existing electrical networks. If ways of organizing data transmission over power grids are discovered, they will have huge commercial success for several reasons:

  • Already existing communications can be used. This will save huge amounts of money on laying and installing information transmission channels.
  • This will open up prospects for collecting data at the most remote points and from all kinds of devices: alarm sensors, smart home systems, meters.
  • Internet communication will be made very accessible by the inclusion of a special adapter: just plug it into an outlet.
  • The network would cover every corner, because even the most remote settlements have electricity.

However, in our country, the prospect of using power grids for data transmission is very vague. Poor communication quality is the very first reason.

The first thing you need to realize the idea of ​​using an AC network is a modem. The device must be equipped with a complex system of microcontrollers for solving problems with testing the quality of communication, protocols and equipment addressing. You will also need a transmitter to enable and disable communication, without violating the integrity of the line.

Plans to increase network performance

Internet network upgrades that are available are still available. There are many models of such equipment on the telecommunications equipment market. Developers offer original and affordable solutions to increase network bandwidth. For example, full-duplex data transmission over local networks, which doubles the channel performance. This is due to the fact that each twisted pair simultaneously transmits and receives information. To do this, you need to change the network adapter to an innovative device.

The limitation of such equipment is that one unit is connected to each port of the hub. Therefore, only the creation of high-performance sections between switches and servers is available. The advantage of the device is that there is no need to track signal collision processes.
