Many friends said: high-speed rail mobile network signal so bad, it is necessary to install WiFi. I believe you have a deep understanding that when the high-speed rail is running, our mobile phones often go into a state of no service. Why is this? Let's get to know.


The main reasons are as follows:


1. Base station signal transmission


2. Signal blind area


3. Environmental interference factors


As we all know, cell phone signal is transmitted by base station. In essence, we call it electromagnetic wave. When the high-speed rail is close to the base station, the base station will send electromagnetic waves to your mobile phone, which will also return the data to the base station.


There will be some signal blind areas at the intersection of base station and base station, such as high-density obstacles, and the signal will be weakened. There is no signal and no service state in high-speed railway. In short, fast speed and frequent base station switching make the mobile phone unable to receive signals. Not only the signals are bad, but also the power consumption of the mobile phone is faster.


For example, GPS signal is required for navigation and positioning, WiFi signal is required for Internet access, and call signal is required for phone calls. These three signals are concentrated on one line, which will inevitably cause interference with each other. At the same time, mobile phones transmit signals through electromagnetic waves, so electromagnetic waves have a great impact on mobile phones. When electromagnetic waves in the air reach a certain degree, it is easy to have no signal for mobile phones , we can only try to change our environment.


Therefore, it will lead to high-speed rail on-line brush traffic Internet access, give us a very poor user experience, high cost, free and stable WiFi is necessary.
