What are 4G networks and what advantages do they give us?
Now it’s hard for us to believe that quite recently parents released their children to walk all day without a mobile phone, and tourists fearlessly went on a wild hike without a GPS receiver. Over the past decade, a real revolution has taken place in the world: telecommunications from an instrument used in emergency cases have actually become part of our way of life. apichart boonsin Shutterstock.com In 2011, the UN included free Internet access in the list of basic human needs. What seemingly unnecessary luxury! In a world where tens of millions of people die of hunger every year, they dare to declare the urgent need for some kind of Internet! Alas, not so simple. Man does not live by bread alone – communications themselves can change our lives. First of all, a person has the right to access information. The sea of data available on the Internet allows you to choose the medical center where you are to be treated, the school where you are going to give the children, the goods you want to buy. And even the political regime: citizens’ awareness of what is happening in the country turns the vote from a formal act like “Nothing depends on me” into a conscious choice. In the same Soviet era, the spread of communication services, they say, was deliberately restrained by party and government policies. Professor Sorbonne Michael Geller even mentions the “critical mass of telephone installation” – when there is at least one telephone for three people, the authorities begin to experience serious difficulties in imposing their will on the population. In Poland, during the riots of 1970–71, the authorities periodically turned off the telephone network: they were afraid of organized speeches. In Russia, the spread of the Internet has made possible the existence of huge movements of like-minded people, in an organized manner defending their rights. In addition, many technologies that will become everyday in the very near future are impossible without guaranteed broadband access: including remote surgeries and online counseling systems, thanks to which patients can contact the best specialists at any time, and those can instantly receive cards diseases of their patients. Cloud technologies, without which, according to forecasts, a business will be unthinkable in the coming years, can only exist if there are reliable, fast and high-capacity channels. Thanks to mobile 4G networks, entrepreneurs can send gigabytes of data instantly and with a high degree of protection against theft. In short, the development of networks providing broadband access now depends on which future we are to live in – civilized or not too much. Alas, 4G technologies in our country have so far been little heard. Neither the business, nor even the average person has yet tasted what LTE networks are and what they eat with. At the same time, the telecommunications companies themselves have already cast off doubts: 65 of the world’s largest operators plan to develop precisely towards LTE. This sounds unusual, but it is Russia that has every chance of becoming a country with one of the most advanced 4G networks. In the second half of May, Nikolai Nikiforov was appointed new head of the Ministry of Communications, and more recently Yota owner Denis Sverdlov became his deputy. This gives Russia hope for a technological breakthrough. Both Nikiforov and Sverdlov are people with a lot of practical experience. The first, while still the head of the government of the Republic of Tatarstan, developed and successfully launched an “e-government”, the second is the general director of the first brand in Russia that launched WiMAX wireless Internet communications in 2009, and in 2011 the most advanced LTE format. So far, LTE devices are designed for a speed of 20 Mbit / s, but theoretically, the fourth generation network allows speeds of up to 300 Mbit / s, which makes possible the work of completely new services. First of all, these are high-quality video conferencing – not on tiny displays of smartphones, but on huge, one-meter diagonal office screens. Participants of such conferences can not just be in different cities, but also move around, for example, in a car: having a webcam on a laptop running on an LTE network ensures full participation in the dialogue. File sharing is getting at all a record speed: for example, a 100 MB file can be uploaded to an FTP server in just 4 seconds. However, for ordinary users, mobile Internet TV will be much more interesting. Already, LTE allows you to transfer real-time HD video — the most important thing is that the servers of the sending side work quickly (YouTube is already “sharpened” for fast video delivery, but most of the web video services are, alas, not yet). The augmented service provided by 4G networks will be augmented reality systems: the cloud server will send hundreds of context clues to mobile devices based on the location of the subscriber and the cityscape that their webcams “see”.
