5G Internet – In the Future, the Web will Follow you Everywhere

When the 5G mobile network is launched in a few years, it will be the beginning of a new era. The network will provide everything from self-driving cars to surgical robotic arms with lightning fast internet. The virtual world will merge with reality.

You sit there at home on the couch talking to an old friend. At first glance, it looks like she’s sitting there living next to you, but the fact is she’s on the other side of the globe.

What you see is a razor-sharp three-dimensional hologram that is transmitted without delay via the 5G network to your augmented reality glasses, which project the figure right into your field of view.

The first generation of mobile networks was launched almost 35 years ago. With 1G, as it was called, it became possible to take the phone with you when you were on the go. It was a technological revolution, and today not many people can imagine a day to day life but a mobile in their pocket.

Now is the time for a new revolution, one that requires a complete overhaul of the global network of mobile masts. With the aim of 2020, researchers and telecommunications companies are working to launch 1G’s technical grandchildren’s grandchild, 5G. The new mobile network will be many times faster than existing networks, with speeds of several gigabits per second.

This means that a full HD quality video can be downloaded in just six seconds, which would have taken seven minutes with 4G and 70 minutes with 3G.

However, higher speed is not the only positive with 5G. In the future, the network will be used by almost hundreds of billions of electronic devices when the so-called Internet of Things allows us to connect cars, clothing, medical equipment, surveillance cameras, door locks and a host of other objects wirelessly to the Internet.

More on the Net Make it Crowded

In 1983, the first commercial mobile phone Motorola DynaTAC 8000x began to be sold in the United States. It could only be used to make calls through the analogue network 1G.

Since the 1980s, new generations of mobile networks have been contributing with further technological advances at about a decade’s intervals. With the transition from 1G to 2G in the 1990s, the mobile signal became digital. Then, for the first time, it was possible to send simple digital messages such as text messages and e-mails from the mobile phone.

About ten years later, 3G’s broadband speeds made it possible to surf the phone. Today, many have become accustomed to streaming TV in HD quality on the phone without any problems, all thanks to our current network 4G.

The new opportunities that each generation has provided have meant that more and more people are now using mobile internet.

According to US analyst Gartner, in 2016, there were around 6.4 billion internet-connected devices in the world. Already in 2020, that figure will be 20.8 billion, ie a threefold in just four years.

Mobile phones transmit audio and data in the form of digital packets on a certain radio frequency, a carrier. By modulating the carrier, the digital packets are stored as oscillations in the frequency of the carrier. The nearest mobile mast detects the signal and passes it on to the neighboring mast. When the signal reaches the receiver, the carrier oscillations are decoded into either sound or data.

To ensure that different radio signals do not interfere with each other, frequencies are regulated by the international organization ITU. Currently, frequencies between 700 megahertz and 2.6 gigahertz are used to handle 2G, 3G and 4G.

Each connection occupies a small portion of the frequency band, so there is simply no room for billions of new devices that transmit information through the air.

Millimeter Waves are the Solution

Older generations use wavelengths between about ten and 40 centimeters. By moving upwards in the frequency range, over 30 gigahertz and up to 300 gigahertz where the wavelength is less than one centimeter, 5G can use a more unused portion of the frequency spectrum.

The problem with letting mobiles communicate at such high frequencies and short wavelengths is that signals are more easily obstructed by buildings and also by banal obstacles such as trees, bushes and rain.

Therefore, Finding a 5G technician is a difficult task these days. Field Engineer allows you to find freelance 5G technicians and you can get connected to them anytime from anywhere.
