Network underground: how not to lose a connection to the subway themes of the day 05.03.2019 at 21:04

Banking and financial news on the website

Now in the Moscow subway there is a connection from mobile operators and Wi-Fi on trains from "Maximalism". Tell how it works and how to solve arising problems in the subway.

wherever modern man, soon followed by come cellular operators. And then Wi-Fi. And the usual books of subway passengers switched to surfing the Internet, social networks and video viewing. Good people get used quickly. If earlier the mere existence of communication under the earth seemed a miracle, now the passengers are actively complaining about the disruption of network or the lack of it in cars. Most of all gets, of course, MT_FREE, Wi-Fi network from the "Maximalism". We have collected the most common complaints of passengers and figured out what to do in a given situation.

First came the cellular operators

mobile operators have begun to build a network in the subway at the beginning of zero: in 2002, the first base station at the metro station "Kurskaya" established "Beeline", in 2004, MegaFon has equipped communication station "Revolution Square". But the connection to the subway was slow to develop. Additional "push" for operators has been the creation of a network of free Wi-Fi in the Moscow metro, the operator of "Maximalism". Work began September 1, 2013, and on 1 Dec 2014 free network has become available in the trains of metro lines.

Cellular operators in recent years is also actively developing the subway. Moreover, the link is now available to subscribers not only at stations but in the tunnels. Of course, the building of networks in the metro has its own characteristics.

How to construct cellular communications in the subway

"the installation of equipment in the tunnel differ significantly from the installation of indoor coverage at the stations, — says technical Director of "Tele2 Moscow" Alexey Kruchinin. — The time interval when the specialists can perform the installation in spans shorter because you need to disconnect the conductor rail and special vehicle. In addition, the different and the equipment itself. The station is a base station, turned into the stretch. This allows you to provide subscribers with a smooth connection at the entrance to the station and departure from it. In the distillation used the so-called feeder cable, which emits a signal along its entire length. Many stretches such cable exists, it uses the metro for their needs and provides operators for communication. This partnership is mutually beneficial: the carrier receives rent for the use of its tail, and the operators save on capital investments."

the Coating of the operators of the "big four" is good enough. So, in "the Megaphone" assert that their networks are covered with all the 266 stations, and more than 100 tunnels are equipped with a communication standard 4G. MTS also reported on the coverage of all stations and plan to the end of 2019 to equip all stages of the 4G network. "Beeline" reported on the coverage of all key stations of the Moscow metro. Coverage of all stations and subway also reported Tele2, but the connection in the stretch still available in some areas of Sokolnicheskaya line, Arbatskaya-Pokrovskaya and Koltsevaya lines. Completely cover all hauls (including stations under construction) the operator plans within three years.

the Free Wi-Fi in the subway: happiness or pain?

Now to subscribers in the subway are available as mobile network operators, as well as free Wi-Fi from the operator "Maximalism". To use it, you either have to watch a few commercials, or connect to a paid service like at home and automatically connect to the network right at the front of the car. By the way, according to the operator, service home use about 10% of the network subscribers. That is, the majority of users prefer the free "advertising" model.

When free Wi-Fi in the subway just appeared, it was a breakthrough: in fact, a unique service to the same. Over time, the euphoria has passed, showered with complaints and questions.

I "picked up" bus now, no mobile Internet, no free

There is a problem faced by almost all users MT_FREE: logging in to network "Maximalism" and connecting at least once, the smartphone remembers the network and is constantly trying to connect to it when connected to Wi-Fi. For example, standing on the street at the bus stop, browsing social networks in your phone. The bus pulls up, and neither 4G nor Wi-Fi.


the fact that the network is "Maximalism" is not only in the metro. "Currently MT_FREE works in the subways of Moscow and St. Petersburg, land transport, buses, two carriers of Petersburg, in "Aeroexpress" trains, trains, CFPP, Vnukovo airport and another 15 regional airports, a network of restaurants of Arkady Novikov, at stadium "Sankt-the Petersburg arena", — said the press service of the operator. — In addition, MT_FREE launched in the city of Kazan and Magadan". In fact, for your gadget is the same network. So, it will try to catch and connect, if your device is enabled auto-connect to Wi-Fi. Exactly the same thing happens when you come home and your gadget sees the home network. Only in this case no problems you are experiencing. By the way, users "paid" version of this service (of course, if ground-based Wi-Fi client is also included in the payment) problems also arise. But for those who are connected via free scheme, the problems start: is not viewed, then and there.

of Course, the easiest way to solve the problem is to turn off Wi-Fi on your smartphone when you are not planning to use it. Incidentally, it is also a safety issue (but more on that below). In "Maximalism" suggested another way: "Users can cancel the network connection in certain types of transport with the help of mobile applications MT_FREE. In the section "connection Settings" you can select the segments to which the device will connect automatically". Thus, if you do not plan to use MT_FREE anywhere except in the metro, just disable the corresponding option. And the problem will be solved.

Went into the car, I can not connect. What to do?

Another common problem was the inability to connect to the network. In "Maximalism" suggested that the network availability is 98%, but the problems still occur. And they can be solved only at night, when the passengers in the subway there. Perhaps the failure is just for your car. Then simply go to another one and the problem will solve itself.

Sometimes the network is working, but the login page does not automatically connect (it happens on some devices). "In that case you need to go to the browser manually and open any http site, for example, — tell in a press-service of "Maximalism". — Simplifies access to the network application MT_FREE. It sends a push notification on network availability MT_FREE. Clicking on a push, the user immediately goes to connect".

it is Also to hinder access some software (e.g., ad blockers). In fact, it's honest: companies need to earn and free Internet kompensiruet need to watch ads.

the Connection without danger

We wrote many times about that public Wi-Fi network is unsafe. After all, you never know who is with you in this network and why. And under a known network can mimic the scammers. How often this happens and how to protect themselves, said the technical Director of Qrator Labs Artem Gavrichenkov.

"Wi-Fi in the subway, really, does not meet the best practices of Wi-Fi-points. However, honestly, little of what the existing network fully meets such high requirements, — considers Artem Gavrichenkov. — The Wi-Fi network safe for the user — a complex process, and such a network will be difficult for the users: they need some big knowledge in technical terms than usual the commuters."

According to Gavrichenkov, the substitution of a Wi-Fi point hypothetically possible, not only in metro: typically, the phone remembers the network and if the device is enabled for auto-connect to Wi-Fi, then it can catch the network simulating MT_FREE anywhere. "With all significant incidents of impersonation of a Wi-Fi point, virtually no — soothes the expert. — To date, neither the phone browser, nor the large organizations that provide services on the Internet, do not rely on the cleanliness of the network operator. From the point of view of companies such as Google, Yandex, Telegram, network MT_FREE no better than the network of the attacker, so methods to protect against it being taken the same. Therefore, in 95% of cases any damage to a user caused can not be, unless there is reason to believe that the person may be the target of targeted attacks.

Moreover, the benefits from such actions, the attackers are unlikely to get. That is why incidents of impersonation Wi-Fi access-point is unlikely."

most of the major sites protected, but issues can arise with incorrectly written applications. Such applications are found even in official sources like the Google Play Market for Android phones. What to do to protect themselves?

says Artem Gavrichenkov:

– to resort to self-discipline when using any Internet resources (to go only to trusted sites, do not login to personal accounts and apps, not to make money, etc.);

– it is possible to be sure to install the VPN client on the phone or just to obtain the VPN settings and enter them in the network settings of the device. However, you must be sure of reliability of the VPN provider and to trust him, because at the time of use of VPN traffic to just go through the owner of the service, and then he will be able to make data-absolutely everything, in principle, is available today to the attacker;

– to consider all the risks first and foremost to remember about self-discipline, and the technical tools to use only when the user knows exactly how they work.

be careful, use only trusted networks and applications and stay in touch. And if you have more questions about the availability of cellular and Wi-Fi underground, write in comments. We will examine the most interesting of them and find a solution.
