Nowadays, mobile phones are already indispensable electronic devices in people's daily lives, and almost all social, consumption and other behaviors require mobile phones.
However, due to the impact of the special environment, resulting in no signal on the mobile phone, seriously affecting the use experience, elevators, underground garages and other places are no signal hardest hit areas, unceremoniously, entering these places, smart phones will immediately become "bricks".
In fact, there are two main reasons for the lack of signal on mobile phones:
One is the baseband chip problem of the mobile phone; the other is the coverage of the base station, if there is a problem with both, it will make the mobile phone become signalless.
In places such as elevators and underground garages, the reason why mobile phones will have no signal is mainly the problem of base station signal coverage. When the base station built by the operator transmits the signal, because it is blocked by the wall of the building, especially in China, the wall of the building is mainly reinforced concrete, and the wireless signal will be greatly attenuated after penetration, so it is impossible to effectively cover the more closed areas such as elevators and underground garages.
Therefore, in order to achieve signal coverage in a closed environment, it is necessary to achieve it through cables, and at the same time, a special indoor distributed system is also built.
However, according to the operator's planning, the indoor distributed system construction will not be carried out for all buildings, because all construction operators need to pay a large cost, and the environment of the elevator room is more complex, basically a closed environment, and the construction of indoor distributed systems has certain difficulties.
It is precisely because of various reasons that the elevator and the garage have no signal, basically become a "magic curse", even if the mobile phone manufacturers work hard in the chip, in the elevator and garage place, it is still difficult to let the mobile phone receive the signal.
For the problem of no signal in the elevator room and garage, China Mobile finally broke this "curse". On November 29, fast technology news, in the relevant departments of Jiangsu Province and the efforts of China Mobile Jiangsu Company, China Mobile Jiangsu Company has successfully completed 66481 elevator signal coverage in the province, completing a coverage rate of 94.97%.
For the underground garage signal coverage problem, 3502 basement signal coverage has been completed, and the completion rate is as high as 140.08%.
Not only that, in the future, the cooperation between China Mobile Jiangsu Company and relevant departments will tend to normalize, constantly summarize the technical and model innovation in the construction process, and establish a long-term mechanism for elevator and basement signal coverage, so that mobile phone signals can truly achieve comprehensive coverage and improve consumer experience.
There is no doubt that the coverage of China Mobile's comprehensive power signal is more conducive to the overall growth of mobile users. On November 22, China Mobile released its October 2021 operating data, and in October alone, the number of mobile 5G package customers increased by 24.299 million.
As of the end of September 2021, the number of 5G package users reached 355.52 million.
Of course, if you want to break the "curse" of no signal in elevators, garages and other places, you need the joint efforts of all provinces to jointly achieve full coverage of the signal by combining mobile, telecommunications and Unicom.
Especially at present, more and more underground garages and elevators appear in China, and the signalless environment will become more, which requires relevant departments and operators to solve problems together.
It is expected that the problem of the future signal "magic curse" will be completely broken.
