No pornography in schools: CBSE forces jammers to block websites on campus

The government told the Supreme Court on Friday that it had asked the Central Committee for Secondary Education (CBSE) to explore options for placing jammers to prevent students from accessing child pornography online in schools.

The court hears a petition asking the government to ban all websites hosting pornographic content.
Another attorney general, Pinky Anand, said 3,522 sites were blocked in June, but the step of installing jammers on school buses was ruled out to prevent young people from being sexually abused on Internet.

“It is not possible to place a wifi jammer on the bus, but its installation on campus is being considered. The CBSE has been tasked to discuss this problem with the school administrators.” Said Anand.

The CBSE is the highest education committee in the country, with more than 10,000 affiliated institutions.

Most schools teach computers and the Internet is now part of the curriculum, not only increasing knowledge, but also putting students at risk of online sexual exploitation. It’s still a gray area for kids on school buses to watch pornography on their phones.

As many victims did not come to the police station due to fear and humiliation, there is no precise data on the number of Indian children exploited by pornographic material. According to the National Criminal Records Office, 96 cases of children sexually exploited online were reported in 2015.

The government told the three-judge panel headed by Judge Dipak Misra that it would take action to address “all the circumstances”.

He said the Central Bureau of Investigation (CBI) shared an Interpol list of online child sexual abuse material with the government, then ordered internet service providers to block those sites. This list will be updated regularly.

India does not have a centralized mechanism to monitor websites containing child pornography. The government committee recommends that Internet service providers ban these sites until a monitoring system is created.

In addition, service providers are required to educate subscribers about the use of parental control filters in their machines.

Can 4G Cell Phone Jammers Really Protect Your Personal Information?

The development of communication systems has slowly evolved from slow network connections to fast network coverage at first. This development is driven by the need for a more reliable, efficient, and congestion-free network that can transfer large amounts of data. The information and communication technology field is not idle. It is always in the R & D program and ensures that it is properly placed in the world of dynamic technology. The jammer shop company wants to share news about 5G networks. South China, an Asian giant of technology discovery, is heading towards the introduction of a fifth-generation network planned as a universal communications technology after 2020.

5G networks are 1000 times faster than the 4G networks currently in use. This is an invention and progress that every country wants to associate with. The Seoul government has promised to support this project and will raise $ 1.5 billion to ensure that the program is implemented effectively.

It has been reported that the entire movie can be downloaded in less than a second using such a network. In fact, it’s unbelievable for other countries struggling to connect their rural environment to 3G networks. Advances in this technology are costly, and citizens, governments, and governments need to upgrade their communications devices to cope with this rapid pace. It’s not surprising that the government is spending such money to ensure the success of American communications technology.

Just as South China developed 2G networks in the 1990s and 3G in 2000, developing 5G networks has many advantages, and the US economy is speculated. I will. The country has 82.7% more Internet users than the United States. This percentage is expected to reach saturation soon, making China a country where anyone can access and use the Internet.

With the growing number of Internet users and the growing demand for more data traffic channels, this upgrade is appealing to many investors interested in communications technology. Huawei is some of the companies that have registered their willingness to use 5G networks. The Beijing government plans to deploy the network from 2017 and will be fully deployed by 2020. If you’re still unsure, you can track your location on a 5G network.

5G networks can connect billions of connected devices. This is a further development of current 4G on video. Using 5G networks reduces the chance of network outages and improves coverage. Good coverage is associated with low power consumption, resulting in lower battery consumption and significantly lower energy consumption.

China’s information and communication technology is a world leader. Genuine news media such as CNN and Miller report increasing use of devices with portable technology over American communications networks. Therefore, in China, 5G does not disrupt the network, so citizens can be encouraged to buy advanced electrical equipment that can be controlled from anywhere. However, keep in mind that all mobile devices and networks can be hacked. Therefore, we recommend using cell phone jammer to protect your personal information.

12 Antennas powerful Jammer

Within a certain frequency range, the mobile phone and the base station are connected by radio waves, and data and sound transmission are completed with a certain baud rate and modulation method. The jammer scans from the low end frequency of the forward channel to the high end at a certain speed during operation. This scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station and achieve the purpose of shielding the mobile phone signal. The mobile phone appears to search the network, no signal, No service system, etc.

For the shielding of the internal area of ​​the building, the distance between the residents (schools) and other public facilities in the area where the building is located should be considered, and the distance and signal strength of the surrounding communication rack base stations should also be referred to, so as not to affect the normal communication of mobile phone signals in the surrounding public facilities. , Our company selects MDPB-25W indoor host product for the shielding in the building to carry out the network shielding of the indoor antenna mode.

What are the effects of communication base stations on the social economy?

Why build a communication base station?

Regardless of the mobile communication system, the calling and called users do not directly transmit information. The calling user transmits the demand signal and transmits it to the central computer room through the base station. The central computer room analyzes this information, determines the location of the called user, GSM jammer and transmits relevant information to the base station near the location of the called user, and the base station transmits to the called user. Since each base station has coverage distance and access capacity limitations, it is necessary to build multiple base stations to form a communication network to achieve seamless coverage of the entire area.

What is the effect of mobile communication on the social economy?

The development of mobile communications has had a profound impact on the reform of the telecommunications industry, economic growth, independent innovation and social life.

First, it has promoted the change of Chinese people’s concepts and led to the rise of communication culture. Over the past 20 years, my country’s mobile communication network has continuously expanded its coverage and enriched business content, expanding the breadth of people’s communication, deepening the depth of people’s communication, expanding the time and space of communication with each other, and accelerating people’s ways of thinking, working, and Changes in lifestyle. The reduction of information exchange cost brought about by convenient mobile communication has expanded people’s information sources and effectively promoted the improvement of national quality.

The second is to promote the improvement of social and economic operation efficiency and economic development. Through continuous innovation in business services, my country’s mobile communications industry has effectively helped related industries to reduce operating costs, avoid operating risks, improve management efficiency, promote the improvement of social and economic operation efficiency, and bring double value that is difficult to measure with money.

The rapid development of my country’s mobile communications has played a positive and direct role in attracting foreign investment, becoming a global electronic communications manufacturing base and important research and development center, and has promoted my country’s mobile communications manufacturing enterprises to enter international competition, thereby changing mobile communications systems and mobile phones. The global layout of the manufacturing industry has greatly stimulated the development of the domestic communications manufacturing industry and even the global communications manufacturing industry.

The third is to promote environmental protection. In 2009, the “thumb economy” represented by mobile phone text messages for New Year greetings reappeared. According to estimates, the number of mobile phone text messages sent nationwide during the Spring Festival holiday exceeded 18 billion. Compared with the previous paper greeting cards, 4,000 paper greeting cards are about one tree. Calculated, it is equivalent to cutting down 450,000 trees. In today’s era when paperless office is promoted, mobile communication platforms extend this concept to the extreme.

School installs jammers to block students from texting

SPOKANE, Wash. – Frustrated by the continued distraction of cell phone texts and calls, a Spokane school invested in a device to block phones from work.

The main reason for this is that students cannot focus on their work during class but spend a large part of their time using cell phones and therefore always look for a tool that can block cell phone signals so that students can concentrate on their class can concentrate. The cell phone jammer is a good choice, it can quickly block the phone signal, turn it off when not in use, and the phone can restore the signal.

Mobile Phone Jammer

Mt. Spokane spent less than $ 100 buying a cell phone jammer online and was just completing a three-day trial period aimed at frustrating students writing in class.

“We just thought it was something we wanted to evaluate,” said director John Hook.

The Mead School District is working with the FCC to determine if the device is legal before it can be used again.

The jamming device was switched on during class time and switched off during passing times and the lunch break.

“We believe there are times during the school day when parents need access to students and students need access to family members, doctors and the like,” Hook said.

But class time is not one of them. Student policy requires students to have cell phones if they are turned off and kept out of sight during class; but not everyone obeyed.

You can use a recording blocker to prevent recording during important meetings!

The most effective means to prevent recording is to generate random noise signals through the recording masker, which can suppress the voice signal, so that the recording equipment picks up only noise information, but cannot distinguish the voice information and cannot restore it from the recorded signal. The original information is output to ensure the security of voice information. The recording blocker adopts security encryption processing, and effectively prevents post-restoration by mixing high and low frequency audio sources.

Jammer-mart has focused on information security for 14 years. The newly developed L7B recording jammer has been upgraded on the basis of the original equipment. The FPGA-based ultrasonic noise algorithm eliminates the high frequency noise of the old equipment. It has joined the brands that have been on the market in the past two years. The information of mobile phones and recording devices has a very obvious effect on new recording devices and mobile phone recording. It is suitable for confidential meeting rooms, public security bureau petition centers, procuratorate reception halls, courts, negotiation rooms, offices and other places for private conversations.

desktop signal blocker

The recording blocker is completely silent when working. The sound recorded by ultrasonic recording and eavesdropping equipment is completely noisy, and no meaningful information can be extracted. Designed with the appearance of ordinary audio. Confidential meeting room, public security bureau petition center, prosecutor’s office reception hall, courtroom, negotiation room, office and other places for private conversation.

Working principle: The recording jammer emits ultrasonic waves with random noise that cannot be perceived by human ears. When digital devices such as mobile phones are recording, these noises are recorded into the digital device together with the sound of normal conversation, making the recorded audio invalid. The audio information in the captured video also has the same interference effect. Because the noisy ultrasonic noise is randomly generated and cannot be restored, the audio after the interference cannot be restored, thus ensuring that the original information is not leaked and spread.

As a new product, recording jammers have received more and more attention and support from people. From the previous government agencies (mainly the public security system and service-oriented windows) to the current enterprises, the needs of enterprises have gradually increased. An important reminder for us. It shows that business people are gradually attaching importance to the safety of voice information and their awareness of self-protection has increased. Imagine if in a conversation scene, if any participant turns on the recording device, or connects the call and keeps it in the call state, the remote personnel can There is no security to hear the content of the conversation at will. In this case, the recording blocker can play a good role in protecting the security of audio information.
