The main reason of unstable signal is that there are many people on campus and the traffic consumption is large, while the number of base stations is relatively small, which is not enough to meet the huge number of students on campus. The solution is to make suggestions to relevant operators and increase the number of base stations. I hope my answer can help you! Thank you~
I know the campus card signal is unstable. I also use a campus card, and I often encounter sudden signal deterioration. If a group activity is held on campus and many students get together, the signal will be particularly poor. Although it is a 4G campus card, the network speed is very slow, generally maintaining a transmission rate of 20Mbps. The advantage of campus card is that it is cheap and has sufficient traffic. The Unicom campus card I use is only 18 yuan for one month, with the national traffic of 20G and the campus traffic of 140g. The campus card signal is unstable due to the following reasons.
There are more people on the university campus, and there are more networking devices. Now there are more and more 4G users, and the number of base stations is limited. If the base station can't bear such a huge number of users, the user's online experience will decline. Now the traffic fee is cheaper than before. The rise of short video and live broadcast has caused many users to watch video and live broadcast on the 4G network, which has generated a lot of traffic and increased the burden on the base station.
The main reason for signal instability is that there are not enough base stations, and the more users who use 4G, the more traffic they generate. For unstable signals, operators can be fed back to increase base stations. If the campus has 5G coverage, you can use a 5G network for another mobile phone.
First check whether any of the following conditions exist:
1.SIM card has insufficient contact with the metal contact of the mobile phone, and then try to insert the SIM card.
2. If the SIM card is damaged or there is something wrong with the mobile phone, you can change the machine for testing to see if there is something wrong with the SIM card or the mobile phone.
3. The current position is a signal blind area or there is no signal suddenly. You can test it in another place and pay attention to whether the cell phone signals of other users around you are normal.
4. When the total traffic generated by surfing the Internet in the current month reaches the package traffic capping value, the system will automatically turn off the Internet access function or speed-limiting network according to the traffic capping rules of your package, and then automatically resume opening next month.
If the above is normal, you can try to operate:
Android phone: Open Settings-About the phone-Status information SIM card status-Signal strength
IPhone: dial the keyboard *300 1# 12345#*, and click Call to pop up the field test startup page, with the signal value displayed in the upper left corner. Yours doesn't show? It doesn't matter. Click on the top left corner to go back and you will see it.
Android phone: Check whether the network access point is set to cmnet (China Mobile), and click Reset to restore.
IPhone: Settings-General-Restore-Restore network settings. However, doing so will clear the WiFi password on the iPhone.
A high school student explained that the dense school staff led to network congestion on the one hand, the installation of shielding devices in schools on the other hand, and the shielding of signals by buildings on the third.
Hello! Hello, everyone, I am the creator of high-quality technology (Comet Ming Ge). At present, I work in a technology company, often participate in scientific and technological research activities, and have written dozens of scientific and technological reports and articles. I have strict research on performance, structure and function, and have a certain right to speak in this industry. In response to this question raised by pen pals, let me explain my professional point of view:
The campus card signal is unstable, I know it very well. I'm also using the campus card, and I often encounter sudden signal deterioration. If a group activity is held on campus and many students get together, the signal will be particularly poor. Although it is a 4G campus card, the network speed is very slow, generally maintaining a transmission rate of 20 megabits per second. The advantage of campus card is that it is cheap and has enough traffic. The Unicom campus card I use only needs 18 yuan every month, with a national card flow of 20G and a campus card flow of 140G. The campus card signal instability is caused by the following reasons.
There are many people in the university campus, and there are many corresponding devices connected to the network. At present, there are more and more 4G users and the number of base stations is limited. If the base station can't bear such a large number of users, the user's online experience will decline. Now the traffic charge is cheaper than before. The rise of short video and live broadcast has caused many users to watch video and live broadcast on 4G network, which has generated a lot of traffic and increased the burden on base stations.
The main reason of signal instability is that there are not enough base stations, and there are many users using 4G. For unstable signals, feedback operation can be given to increase the number of base stations. If the campus covers 5G, you can change your mobile phone and use 5G network.
The main problem is time.
Campus cards have nothing to do with the network. Campus card is the name of the package fee of network operators. There are many reasons for this. The first possibility is that the mobile phone is easy to cut off, and the network coverage may be poor nearby!
