Is there wireless for bullet train high speed rail? Is there internet access?

Only some high-speed trains have WiFi networks.

Train WiFi has been in pilot operation since 2012. The original Jiangsu Jinghai Boyuan Company has trial-run its wireless Internet access system on more than 60 trains in Guangzhou Bureau, Hohhot Bureau, Kunming Bureau, Zhengzhou Bureau, Beijing Bureau and Lanzhou Bureau. Passengers can access information, movies, travel guides, and more via the Wi-Fi provided.

However, at this time, Wi-Fi services were still limited to local area networks.

Until November last year, T809 from Guangzhou East to Kowloon, Hong Kong" target="_blank"> T809 train, it can be regarded as a passenger train that officially opens free Wi-Fi service.

Different from the previous pilot wireless WiFi, the T809 train is not a local area network, passengers can access the Internet as long as they use mobile phones and other devices to connect to the WiFi in the car, and enjoy services such as browsing the web, IM chatting, and watching.

At present, WiFi on trains is generally converted into Wi-Fi through on-board Wi-Fi devices, which convert 3G or 4G signals along the line. That is, the device first receives the network signals of the three major operators along the way, and converts them into hotspots on the train for passengers to use.

However, on a speeding train, how to ensure a good WiFi experience may be a test. When the train reaches speeds of 200 to 300 kilometers per hour, the signal attenuation is very high. And if you switch frequently between the networks of the three major operators, the signal will be unstable.

In addition, in sparsely populated areas, if the coverage density of the operator's base station is not large, the signal will be affected. If you use satellites to transmit signals, the cost is too high and the technology is not mature.

Hello, up to now, all Fuxing ships have been able to connect to high-speed rail wifi, as long as the ** handheld high-speed rail APP, one-click connection to high-speed rail wifi, the first connection of the day and a G traffic.

The specific connection method is as follows:

1. Turn on the mobile phone wifi, search for "high-speed rail wifi", and connect.

<>4. When you recognize your mobile phone, click "One-click Login".

5. After logging in to the software, you can carry out "authentication", and you can access the Internet if the authentication is successful.

High-speed railway is a railway system that is designed with a high standard of potato changyan and can allow trains to run at high speed. The world's first official high-speed rail system was the Tokaido Shinkansen, which opened in 1964, connecting Japan's three major metropolitan areas, including Tokyo, Nagoya, and Osaka, and contributing to Japan's rapid development.

Its design speed is 200 km h, so the initial speed standard for high-speed rail is 200 km h. Later, with the advancement of technology and the speed of trains, different countries in different eras have different definitions of high-speed railways, and stipulate detailed technical standards for their respective high-speed railway levels according to their own national conditions, and the train speeds, railway types and other numbers involved are different.

1. The signal coverage on the high-speed rail is not very extensiveWhen we use data and wifi on the mobile phone, we need to have the support of the base station, although the network coverage of the three major operators in China is relatively extensive, but some remote areas still do not achieve signal coverage, so even if you can connect to wifi, it can not be used normally.

2. There are too many users at the same timeGenerally, the number of people in the carriage is relatively large, and many people's mobile phone traffic is not very sufficient, so they will try to connect to wifi, when many people connect to a wifi at the same time, the network speed will be affected, perhaps the network speed of wifi is less than 2G.

3. The speed of high-speed rail is too fastRunning too fast will also cause the network speed to drop by the wheel, and the high-speed rail will often use a fast speed to get from one area to another, so the wifi signal will not be very stable.

How to connect to wifi on the high-speed rail.

Tools Raw materials: OPPO RENO4, handheld high-speed rail.

1. Turn on the high-speed rail in the palm of your hand.

2. Switch the page from "Home" to "My".

3. Click Login Now.

4. Enter the mobile phone number, 12306 password and the last four digits of the ID card, and log in.

<>6. Select the wifi connection in the pop-up box.

It is recommended to use the high-speed rail in the palm of your hand, I hope it can help you, and the Year of the Rabbit in 2023 is auspicious.

There are several reasons why Wi-Fi is not available on high-speed rail:

The speed of high-speed rail moves fast, and the transmission and reception of signals will be interfered with and limited, resulting in unstable signals and affecting network connections and transmission speeds.

The areas and terrain through which the high-speed rail passes are varied, and the coverage of the signal is unstable, which is prone to signal loopholes and faults, resulting in unstable network connections.

The dense crowd on high-speed rail and the large number of users using Wi-Fi will cause network congestion and affect network speed and stability.

In order to ensure the safety and stability of train operation, the high-speed rail system needs to strictly control the electromagnetic interference of the train to prevent the impact of radio interference on the train equipment, so it is forbidden to use radio equipment such as Wi-Fi on the train.

To sum up, the main reason why Wi-Fi cannot be used on the Gaogao Dan Slider is because of problems such as unstable signals, Qila network congestion, and electromagnetic interference control.

The specific connection method is as follows:

1. Turn on the mobile phone wifi, search for "high-speed rail wifi", and connect.

Wireless Kaijing Network Regulations:

On January 24, the official wifi entrance of China Railway, the "Pocket High-speed Rail APP", has been able to be used, which can provide smooth and free high-speed rail WiFi services for the majority of passengers on the basis of ensuring user information security.
