Why is the high speed rail wifi so slow, and how to solve the slow Internet access speed of the high

Due to technical and other reasons, high-speed trains and bullet trains will not have wireless Wi-Fi coverage for the time being. At present, WiFi on trains is generally converted into WiFi through on-board WiFi equipment. 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.

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.

Dear, the speed of high-speed rail is fast, there will be occasional network instability, and passing through the tunnel will also affect the network speed slightly. We will continue to optimize product functions to provide better services for everyone's travel. Refills

In the same way, the WIFF garbage of the high-speed rail is not good. If you can't even brush Douyin, it's better not to have it. I was even more angry at looking at such a garbage wiff.

1.The reason for the slow speed of high-speed rail Internet access.

Slow network connections on high-speed rail are due to a variety of factors, including but not limited to the following:

Signal coverage is limited: The high-speed high-speed rail has limited the signal coverage area of the 4G network, which will affect the speed of the network connection.

Network traffic overload: The network on high-speed rail needs to meet the needs of passengers on board, and as more people use the network, the network speed decreases.

Network infrastructure limitations: There are limits on network equipment and storage space on high-speed rail, which can also have an impact on network speeds.

2.How to solve the problem of slow Internet access of high-speed rail.

In view of the problem of slow network connection on high-speed rail, we can try the following methods to solve it:

Use a VPN: Some users have found that they are able to solve the problem of slow internet connections on high-speed rail through VPN connections. Virtual Voicemail Networks (VPNs) can provide better encryption, which can give you better access to restricted**.

Try airplane mode: In some cases, switching your device to airplane mode and then reconnecting to the network may change the protocol between your device and the network, which can improve network speeds.

Switch carriers: If you feel like you're using a carrier network that's too slow, try switching carriers to see if you can improve your internet connection.

Optimize device settings: When using the network on high-speed rail, we can also try to optimize our device settings to improve the network connection speed. It also includes ways to optimize device operation and settings, such as updating device drivers, clearing caches, and more.

3.Use the hot spot function of the hand round jujube machine as an alternative.

If you have tried all the above methods and still can't solve the problem of slow network on high-speed rail, you can try using your phone's hotspot feature as an alternative. In fact, in some cases, using a mobile hotspot can be faster than using the network on the high-speed rail.

4.Summary.

Slow network connections on high-speed rail are a common problem today, mainly due to a variety of reasons, including limited signal coverage, overloaded network traffic, and network infrastructure limitations. These issues can be attempted by using methods such as VPN, airplane mode, or switching network service providers. If that still doesn't work, using your phone's internet hotspot feature is also an optional alternative.

The slow speed of high-speed rail is due to the fact that high-speed rail often passes through mountainous areas or sparsely populated places, and the network signal coverage rate is low. Another is that the interior of the car is closed, and the signal propagation is slow.

I summarized the main reasons for the following:

1. China's railway network is long, and most of them are distributed in rural and suburban areas, with few base stations and insufficient coverage;

2. When the railway speed, the Doppler effect and the multipath effect will have a great impact on the signal quality;

3. When the train is running at high speed, the mobile phone signal needs to be quickly switched between different base stations, and the call may be dropped and the network may be disconnected if the switch is not timely;

4. The terrain through which the train passes is more complex, and mountains, tunnels, rivers and desert areas are not conducive to the construction of base stations, and these areas are prone to mobile phone service;

5. The indoor space is closed.

The interior of the high-speed rail carriage needs to be controlled internally, and the glass windows of the carriage are equipped with metal coatings to reduce heat loss, but these coatings can also block the entry of electromagnetic signals, which also leads to signal deterioration. Generally, the train is an iron carriage, and the body penetration loss is large. The loss is different in different positions, and the signal is better by the window.

6. The driving speed is fast, resulting in fast signal switching.

The signal of the mobile phone needs to be transmitted between the base stations. The speed of high-speed rail operation is very fast, the speed can generally reach 200-300 kilometers per hour, and when running at high speed, the mobile phone signal will be constantly switched between different base stations, which will cause signal delay or even interruption.

In fact, the speed of the high-speed rail network is slow, which is not a good thing, you can use this time on the train to read a book and take a break; Or look at the scenery outside the window, think about some worries in the near future, and think about some future plans, etc.

However, you don't have to worry too much, the relevant departments of the railway have been trying to solve this problem in recent years, and I believe that they will soon overcome technical problems such as fast train running speed and car body signal attenuation. Let's wait and see!

The phone will be distracted by some objects, so that there is no signal, or the network speed is slow.

The high-speed rail runs very fast, and the distance radius covered by each base station is only about 1 2 kilometers It is difficult for the mobile phone to keep up with the normal signal under frequent switching at such a high speed.

Because the mobile communication signal on the high-speed rail is interfered with.

There is wifi on the high-speed rail, but it needs to be connected before it can be used normally.

1. If the high-speed rail wifi does not have a password, passengers only need to turn on the wireless LAN. Then go to find the high-speed rail wifi, and you can use it after the direct connection is successful.

2. If the wifi on the high-speed rail requires a password, the wifi password will be posted in a very conspicuous position. When you find the high-speed rail wifi, enter the password. However, it is usually necessary for passengers to scan ***, and then the software can only be used after the eggplant cavity.

3. Passengers first find the wifi of the high-speed rail, and then select connect, and then they will automatically jump to the ** page. At this time, passengers need to click on the software, wait until the installation is completed, and operate according to the specific process, so that they can quickly connect to the wifi and use it normally.

At present, only some Harmony trains will have WiFi, but Fuxing trains are fully WiFi covered. If you really don't know how to connect to the high-speed rail wifi, you can consult the staff on the train, and then go to operate according to the steps.

Although it is possible to connect to wifi on the high-speed rail, it should be noted that the network speed is very slow, and even a page cannot be loaded. Mainly because the wifi is the cooperation between the railway bureau and the operator, the location of the high-speed rail is a little biased, and the cost of repairing the high construction is not proportional to the income, so the wireless network will not be built across a road section. In addition, there are a large number of people connected to the wifi, so it is easy to get stuck after connecting to the wifi, and it can also be said to be useless.

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.

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.

Summary. Hello dear and happy to answer your <>

There is wifi at the high-speed rail station. There are two kinds of wifi for high-speed rail: one is pure LAN, and now some high-speed railways have been equipped with it for communication between personnel within the train, and for carriages on the subway.

There is also a kind of storage on the server, such as a large number of **, games and other content, for LAN entertainment, which is very rare, and passengers do not buy it. Generally, we call this kind of car wifi.

The speed of high-speed rail is very fast, capable of reaching 360 kilometers per hour. When taking the high-speed rail, if the speed of the high-speed rail is very fast, even if we use our own traffic to play with the speed of the mobile phone vehicle will affect the quality of the signal, even if we play **, there will be inaudible and intermittent situations. Therefore, even if WiFi is installed on the high-speed rail and it is fully covered, the network speed will still be very poor when the high-speed rail is running at high speed and slow speed.

Targeting this phenomenon.

Summary. Hello, dear, I'm glad for your question, in general, there is wifi on the high-speed rail, but it depends on the different high-speed rail trains in different regions. Generally speaking, newer high-speed rail trains have WiFi service.

Hello, dear, I'm glad for your question, under normal circumstances, there is wifi on the high-speed rail, but the sail is in a state of hand according to the different high-speed rail trains in different regions. Generally speaking, newer high-speed rail trains have WiFi service. Potato loss.

At this stage, most high-speed trains have wifi services, which can be provided to passengers. The wifi services provided by different high-speed rail companies are also different, some can provide free wifi, some can use wifi for a fee, some can provide better wifi service, and some high-speed rail does not have wifi service. In general, the Peiqing people are talking about taking the first class seat to get free wifi service and disadvantages, and other seats may need to be used for a fee.

For specific information, please also check the relevant information of the local high-speed rail company.

Generally, there is wifi on the high-speed railway. There are two kinds of wifi for high-speed trains: one is pure LAN, which is now equipped with some high-speed trains for the blind flow between people in the train, and the other is for **** in the subway car.

There is also a kind of storage of a large number of **, games and other content on the server, which is used for entertainment on the local area network, which is very rare, and passengers do not buy it. Generally, we call this kind of car wifi. Usage:

The fastest high-speed rail in China has reached 300km h, and in such a high-speed driving state, the wifi signal in the high-speed rail carriage will naturally be intermittent and unstable. Especially when the high-speed train travels to a remote place or passes through a tunnel, the wifi signal in the carriage becomes an ornament. At this point, even though people's phones show a good wifi signal, in reality it doesn't have a network and can't get online through it.

When you take the high-speed train, there are a lot of people in one carriage. In this way, the wifi signal in the high-speed rail will be overloaded, the network speed will be seriously diverted, and the Internet will not be able to access the Internet.
