Cell phone jammers and signal blockers in China


Mobile communications and mobile Internet as well are widely spread in China. And by widely spread, we mean you will barely find a person without a smartphone constantly surfing the web. Until now, there are three mobile carriers in China. The oldest and the biggest one is China Mobile. It uses GSM, 3G TD-SCDMA, and 4G TD-LTE standards. The second carrier is China Unicom, it has used GSM and CDMA standards, as well as TD-LTE, WCDMA, and CDMA2000, but in 2008 it sold its CDMA business to China Telecom company, which became the third mobile carrier. Now it has WCDMA and CDMA2000 standards too.


Mobile Internet

The first 3G network was launched in 2008 by China Mobile, and since that time – mobile Internet became extremely popular in PRC. As the Ministry Of Information Technologies reports, there are 750 million of users of mobile Internet in the PRC now. And their quantity has increased dramatically during the last 11 months, as well as the income of Chinese telecommunication companies. Experts are sure that the growth will still remain and mobile Internet will continue to conquer the country.

The PRC was among the first countries, which started building its own 4G network. The fourth generation of communications is such mobile standards, which can provide 100 Mb/sec for mobile and 1 Gb/sec speed for stationary users.

Chinese carriers use a special TD-LTE standard developed in China, it provides huge speeds, starting from 100 Mb/sec, while 3G networks are able to provide up to 3,5 Mb/sec speed. China Mobile launched its 4G network in 2009, and now it is available in all major cities. The company has already built and launched more than 20 thousand base stations. LG, HTC, Huawei, and ZTE have already launched TD-LTE-ready smartphones.



China Mobile network

As you probably understand, the most widely spread mobile network that covers the most significant area is the China Mobile network. That company covers all the inhabited areas, including the remote, hardly reachable locations. China Unicom works well mostly in big cities, and in some places, especially in western regions, the reception may be weak.

There are no big differences between China Mobile and China Unicom. They both work with the classic GSM, so your phone will still work there. But if you want to use a 4G connection there, you will have to get a local smartphone because most of LTE-based smartphones have well-known compatibility problems with TD-LTE. Also, if you plan your visit to China, you should know that all the incoming calls are not free there,  and there are lots of such little catches in Chinese carriers' service plans.

The PRC also has its own global navigation system called Beidou. It became operational in 2011 with ten satellites in use. It covers a whole Asia-Pacific region, so it is hard to call the Beidou system really global. Well, GPS will still work there. They plan to improve the system significantly by 2020.


China Mobile jammers

In the world, the issue of information protection is not just reinsurance but a real necessity. With the development of technology, the opportunities for attackers to access your personal information, trade secrets, or compromising data are increasing. According to statistics, the most common reason to buy a jammer is to suppress the GPS and GLONASS signal to avoid unauthorized tracking of your location using a hidden GPS tracker. The most significant interest among buyers is the car GPS jammer for installation directly in the car. 

Well, in conclusion, we may say that China has the biggest and the most advanced market for mobile communications, and it is growing faster than anywhere. The problem is that there are lots of particular features that distinguish the Chinese market from any other market in the world.
