What are 4G networks and what advantages do they give us?
Now it’s hard for us to believe that recently parents let their children go out all day without a mobile phone, and tourists fearlessly went on a wild trip without a GPS receiver. Over the past decade, a real revolution has taken place in the world: telecommunications from an emergency tool have actually become part of our lifestyle. apichart boonsin Shutterstock.com In 2011, the UN included free Internet access in its list of basic human needs. What a seemingly unnecessary luxury! In a world where tens of millions of people die of hunger every year, they dare to declare the urgent need of some kind of Internet! Alas, not so simple. Man does not live by bread alone – communications alone 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 a medical center where you have to be treated, a school where you are going to give your children, goods that you want to buy. And even the political regime: citizens’ awareness of what is happening in the country turns voting 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. Sorbonne professor Mikhail Geller even mentions a “critical mass of telephony” – when three people have at least one telephone, the authorities begin to experience serious difficulties in imposing their will on the population. In Poland, during the unrest of 1970–71, the authorities periodically disconnected the telephone network: they feared organized performances. In Russia, the spread of the Internet has made it possible for huge movements of like-minded people to organize their rights to be organized. In addition, many technologies that will become daily routines in the near future are impossible without guaranteed broadband access: including remote surgery and online consultation systems, thanks to which patients can contact the best specialists at any time, and they can instantly receive cards diseases of their patients. Cloud technologies, without which, according to forecasts, business will be unthinkable in the coming years, can exist only if there are reliable, fast and high-bandwidth channels. Thanks to mobile 4G networks, entrepreneurs will be able to send gigabytes of data instantly and with a high degree of protection against theft. In a word, the development of networks providing broadband access now depends on what future we have to live in – civilized or not. Alas, so far little has been heard about 4G technologies in our country. Neither the business, nor even the layman have yet tried out what LTE networks are and what they eat with. At the same time, telecommunications companies themselves have already cast aside doubts: 65 of the world’s largest operators plan to develop specifically towards LTE. This sounds unusual, but it is Russia that has every chance to turn into a country with one of the most advanced 4G networks. In the second half of May, Nikolai Nikiforov was appointed the new head of the Ministry of Communications, and most recently, Yota owner Denis Sverdlov became his deputy. This gives Russia hope for a technological breakthrough. Both Nikiforov and Sverdlov are people with great practical experience. The first, while still being the head of the government of the Republic of Tatarstan, developed and successfully launched the “electronic government”, the second is the general director of the first brand in Russia, which launched the WiMAX wireless Internet connection format in 2009, and in 2011 the most advanced LTE format. So far, LTE devices are designed for speeds of 20 Mbit / s, but theoretically, the fourth-generation network can provide speeds of up to 300 Mbit / s, which makes it possible to work completely new services. First of all, these are high-quality video conferences – not on tiny displays of smartphones, but on huge, meter-sized, office screens. Participants of such conferences can not only be in different cities, but also can move around, for example, in a car: the presence of a web camera on a laptop working in an LTE network ensures full participation in the dialogue. File sharing is becoming record-breaking at all: 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 transmit real-time HD-video – the main thing is that the sending server’s servers work efficiently (YouTube has already been “sharpened” for fast video delivery, but most of the network’s video services are, alas, not yet). Augmented reality systems will become a fantastic service provided by 4G networks: the cloud server will send hundreds of contextual prompts to the screens of mobile devices based on the location of the subscriber and the city landscape that their webcams see. Mobile technologies will also be indispensable in the fight against natural disasters.
