Very high speed internet: what is the transmission mode?
Less expensive than ADSL or fiber, the Hertzian Beam (FH) meets important connectivity needs. Thus, the National Plan for Very High Speed has provided for the deployment of this solution. The Hertzian Beam technology makes it possible to cover remote, risky or “white” geographic areas. Close-up on this mode of transmission of the Internet at very high speed.
The Hertzian Beam: how does it work?
The Hertzian Beam transmits information, data via radio waves at frequencies ranging from 1 to 86 GHz. As you will have understood, this wireless technology is part of the National Very High Speed Plan which aims to access an internet connection of more than 30Mb / s throughout the territory in 2022.
You can already inquire and identify what you need to know about the microwave, an excellent alternative to ADSL and fiber. Indeed, it turns out to be less expensive and more interesting to install a transmitter and an antenna at each user rather than using the cable to ensure the broadband internet connection. Thanks to “wireless” technology, directional antennas transmit waves over very long geographic distances.
Broadband Internet: what are the advantages of the microwave?
The microwave has many advantages, starting with the very high start Internet up to 10 Gbits / s. Wireless technology transmits all types of flows: voice, data, video. In addition, the work is less expensive, the installation is quick, easy and scalable.
A microwave link is functional after 4 or 5 days. This solution has a better quality / price ratio compared to fiber or ADSL. It also solves the saturation problems encountered on free band radio frequencies.
Very High Speed Internet access remains an asset for professionals and companies located in an area not eligible for optical fiber or ADSL. Let us not forget that the microwave link is a constantly evolving technology.
Continuous research aims to minimize the impact of environmental obstacles that affect the transmission of radio waves. In this regard, experts are betting on higher frequencies which can reach 240Ghz. Their objective: to deliver internet speeds that approach the capacities of optical fiber, ie tens of Mbit per second.
What are the disruptive elements?
But in order for the waves to be able to propagate from point A (transmitting station) to point B (receiver), it is necessary to clear line of sight. Indeed, the buildings, the relief or the vegetation cause emission losses. At least, the area called “first Fresnel ellipsoid” should be cleared.
Climatic and atmospheric conditions also affect the transmission of radio waves. It no longer deploys in a straight line when they cross an area with a high electromagnetic index, in the event of heavy precipitation or atmospheric refraction.
In other words, it is advisable to carry out static studies beforehand in order to anticipate climatological changes as well as the displacement of the wave according to the curvature of the earth.
