We saw some details from movies:To avoid tracking of evil organization or reactionary gang, leading actors broke into pieces or threw into River.Here comes a question ,can obtain private information by mobile phone using in our real world ?In other words,are we facing the problem that tracked by smart phones using ?The answer is YES.Today ,we are going to share 3 ways to avoid the tracked problem.Before talking about these ways ,we’d like to remind you in previous that the best way is from cell phone signal jammer.
A mobile phone jammer or blocker is a device which deliberately transmits signals on the same radio frequencies as mobile phones, disrupting the communication between the phone and the cell-phone base station, effectively disabling mobile phones within the range of the jammer, preventing them from receiving signals and from transmitting them.If you need to block internet connections in the location around you then you must understand one thing: you cannot block cable internet unless you would cut that cable. But other types of internet like the wireless one powered by WiFi and Bluetooth connections can be easily jammed.
In prisons use this 4G jammer device
In January, NTIA said its researchers installed the jamming technology in a utility closet adjacent to a 13-by-eight foot cell on the ground floor of the prison’s housing unit, according to the study. It successfully blocked cellphone transmissions in commercial bands between 700 and 2170 MHz, but did not disrupt commercial transmissions when monitored at 20 feet and 100 feet outside the cell, said the study.
To completely cover a prison facility, a fleet of the systems would be required — up to 100 jamming systems — which could lead to significant power issues, NTIA’s study said.
“The results indicate the potential for localized impact of this micro-jamming technology,” Williams said. “That is an encouraging sign that brings us closer to a solution that will make our communities safer and help prevent the continuation of criminal activity from inside prison walls.”
5G is coming, this is a technological progress or a disaster
China has a tendency to overtake the United States in communications. Britain’s Foreign Minister Boris Johnson said at a recent event that Chinese technology firms could overtake the U.S.
“The Chinese are about to win. They’ve got 5G. They’ve found out a way. Everybody’s going to be getting stuff on their gizmos through the Chinese system and not the American system. Our communications may become less secure in the future.” Johnson said, according to The Guardian newspaper
While the U.S. has been pushing back against China, the world’s second-largest economy has been looking to leave its mark on other countries in terms of 5G. Huawei has been lobbying Australian politicians. The FT revealed that the Chinese giant was the biggest corporate sponsor of overseas trips for Australian lawmakers. On Thursday, the Portuguese arm of telecoms firm Altice teamed up with Huawei to roll out 5G networks. Yet most people are unaware of huawei’s and China’s sinister intentions. This is the first step in China’s attempt to control the lifeblood of the world. Clearly, huawei’s actions are driven by the support of the Chinese government. On the one hand, the development of 5G communication will be promoted; on the other hand, the future communication network will be controlled secretly.
Predictably, communications control from China
This is a very worrying fact. This means that our means of communication may be controlled by China in the future. American telephones could be monitored by China at any time to steal our confidential information. So, the defense department is considering developing cell phone signal jammer to prevent this from happening. But the plan is still awaiting congressional approval, and the FCC could get into trouble.
Even though the United States and Britain are concerned about this situation. But the Portuguese have already signed a technology deal with huawei. While celebrating their 5G network’s lead in the world, they did not consider that their communications were likely to be monitored by huawei.
China has been ramping up its 5G ambitions and the trade war, while a push for fairer economic treatment according to Trump, could also be seen as an attempt to buy some time and breathing space to figure out how to get ahead in the telecoms race. 5G after all is clearly more important than what has come before. Once China has established an edge in 5G, it will be a devastating blow to the US and European countries. Perhaps America will no longer have secure communications.
