Wifi on the ring line of the Moscow metro - rapid test
A couple of days ago, they announced the launch of testing free wifi on the ring metro line in Moscow, and yesterday I was accidentally brought there. There was free time, so I decided to take a ride from Komsomolskaya to Kurskaya through the Park of Culture and see how it all looks from the point of view of the passenger.

Nicely. All bums with laptops will soon crawl to the ring.
While the service is not wildly popular - very nice. As people get through, problems with speed and stability can begin, I doubt that access points can pull more than a dozen clients each normally.
Of course, it would be desirable that in the future wifi covers both radial lines and all stations. In all cities.
Well, for complete happiness, in general, all public transport - from minibuses to airplanes. :)
"36 trains of the Koltsevaya line are already equipped with access points" "The test period will last 3-4 months, Wi-Fi will work for free." - but it is not clear, for free at all or for free during the test
“In 180 cars installed 3G equipment routers. The range of the Wi-Fi access point is defined within each individual car in order to avoid bandwidth problems at stations ”
"... at present, the power of the access point is enough for seven users simultaneously. In the future, it is planned to increase the number to 20 ..."
"... The new service will be tested for three to four months, after which the Internet should appear on all branches of the metro ..."
“Most likely, passengers will have free basic access to view websites, mail, but without the ability to watch videos or download torrents.”
Pro equipment: “Non-industrial routers are used in the test zone - D-link DIR 456 and Huawei, HSDPA„
About plans and cost: “Let's look at the test results, transport workers are still afraid that users will stick and slow down passenger traffic. Most likely, basic access at low speeds will remain free - Freemium „
About why the ring was chosen for the tests, despite the short travel time: “It was for these reasons that the ring was chosen: a) a lot of people, moreover, foreigners and visitors from train stations and aeroexpress trains who need to be given an opportunity to orient themselves) than on other lines - you can calmly potest everything before industrial launch „

Used tools:
- Testing time - from 12:00 to 12:30 and from 14:00 to 15:00
- The subway train, for convenience, took the last car - fewer people
- Tablet on Android (Lenovo Thinkpad, android 3.1), phones on Android (Huawei Honor, 2.3.6) and WP7 (HTC Mozart)
- Browsers - Firefox and IE, speed testing - Speedtest, maps - Yandex, Google.
- I went to the forums, posted to threads, read news, uploaded a few pages full of pictures (ixbt, mobile-review reviews), found the desired address in Yandex maps and laid a route to it.
Feels like:
- Access points are in the cars. Therefore, when there are two trains at the station, the dots are lit up with a dozen. From the last car in the tunnel there were two points.
- The speeds do not depend on the location of the train, in the tunnel it or at the station.
- Five measurements were made (Prospekt Mira, Krasnopresnenskaya, Paveletskaya, Kiev-Oktyabrskaya, Paveletskaya-Taganskaya sections), the minimum download speed was 1.8 megabits, and the maximum was 2.4. Download speed - 350-400, ping ranged from 200 to 270.
- So far, everything is working stably, there are no re-connections, which point I hooked on, and I sat on it (I rode in two trains, Komsomolskaya-Novoslobodskaya, Novoslobodskaya-Kurskaya).
- The Internet is from MTS, it can be seen, at least, by the names of access points - MTS + “digital_code”.
Results and impressions:
Nicely. All bums with laptops will soon crawl to the ring.
While the service is not wildly popular - very nice. As people get through, problems with speed and stability can begin, I doubt that access points can pull more than a dozen clients each normally.
Of course, it would be desirable that in the future wifi covers both radial lines and all stations. In all cities.
