Ten years ago, in an era when mobile phones didn't have many fancy functions, people were most concerned about call quality. In the era of smart phones, when manufacturers are lavishly rendering smart phone hardware performance, camera quality, and system experience, everyone seems to have gradually ignored the call quality, which is still very important for mobile phones.
A study commissioned by the British Communications Authority found that cheap mobile phones are better at capturing weak signals from 2G networks than flagship phones, and some smart phones require ten times the minimum signal strength to make calls than non-smart phones. On average, the minimum 2G signal strength required by smartphones is 7 times that of non-smart phones. The situation is similar under 3G and 4G networks. Smartphones require stronger signals to send and receive data.
Why the smart phone signal is not as good as the functional phone
After the emergence of smart phones, there are indeed many situations on the network signal. Part of the reason is that the antenna system of the smart phone is worse than that of the functional phone. Because the antenna design of the smart phone, some products are less sensitive to information reception than some bands. Functional machine with external antenna.
The second is the congenital problem of smart phones, because smart phones have GPS navigation, WIFI and other functions, these functions require mobile phones to receive and send signals, plus mobile phone call signals, a variety of signal functions are concentrated in a small place, signal Too many "fights" have also become an important reason for bad signals.
How to solve the problem of bad signal?
Since the signal of the smart phone is not as good as that of the functional phone, how should we deal with it if the signal is bad? For the bad signal, the editor has collected some solutions.
1. Check if your current location is in a signal blind zone. Blind zones include areas outside the network coverage area, such as workshops, factories, suburbs, rural areas and other places where network communication facilities have not been built, and urban signal mobile phones that cannot be covered by shielding and blocking signals. Places, such as office buildings, bar rooms, elevators, underground places, buildings, etc.
Solution: Get out of the place where there may be no signal and make a call in a wide area.
2. If there is no problem with the location, it may be caused by the interference facilities. The mobile phone receives the signal through electromagnetic waves, so the base station establishes a connection between the mobile phone and the radio wave, so as to achieve the purpose of voice communication. The interference of electromagnetic waves will affect the signal of the mobile phone, and this situation usually occurs in the examination room.
Solution: Find the surrounding signal interference equipment, turn it off or remove it.
3. Temporary failures may occur when the network is particularly busy, which will also have a certain impact on the mobile phone signal. For example, in a prosperous business district, there are often cases where calls cannot be made and others cannot come in, especially during peak periods, there are often delays in commuting and holidays.
Solution: Avoid the prosperous business district, the signal condition will automatically improve during peak hours.
4. If the mobile phone has no signal caused by external factors, it may be caused by unstable battery voltage. The signal receiving circuit has insufficient power supply and the voltage fluctuates, so the signal reception cannot be stabilized. In this way, the mobile phone cannot access the Internet, and even the phone cannot be dialed.
Solution: Change to a higher-quality phone, and the signal problem will be fixed.
5. If the surrounding signals are okay, you can also check the software of your mobile phone to see if there is software that activates the flight mode, or the flight mode is invoked on a regular mission, and whether some software will interrupt the signal connection when it is turned on. Try to clean up the software running in the phone's memory, or restart it.
In addition, if the phone often has no signal, you can also see if it is the SIM card. Take out the card and try it on another mobile phone to see if it is the problem of the phone or the SIM card, lock the source of the problem, and then prescribe the right medicine.
If the lock is a cell phone problem, it may be that the cell phone’s receiving circuit is faulty, most of which are in the antenna switch. Of course, this kind of repair requires professional personnel.
