Jammers are often used near prisons and detention centers to prevent detainees and detainees from communicating without authorization and unsupervised with the outside world. Brazil, India, New Zealand and Sweden are countries that have exempted or are considering exemptions for the use of mobile phones and Wi-Fi jammers in prisons, while this has been legal in the UK since 2012. A seller of cell phone jammers, Los Angeles-based Global Protection & Intelligence Inc., offers models ranging in price from $1,600 to $2,600. They prevent mobile phone frequencies from entering a specific area, with more expensive models blocking larger areas. The company sells a briefcase-sized device that can cover a radius of about 150 meters and a model the size of a cigar box that maintains a conference room without a signal. Radio jamming devices, more commonly known as «jammers», have been the subject of recent news. There have been many reports of frustrated citizens buying jammers to minimize the annoying cell phone chatter that has become the norm in places like movie theaters, classrooms, and public transportation. While some may praise these individuals for ingeniously solving a seemingly never-ending problem, the reality is that jammers are banned in Canada. Cell phone jammers can have a significant impact on the public`s communication rights, as well as the risk of major harm if they interfere with emergency responders` communication devices. In an emergency, the use of a cell phone jammer can delay emergency care. Many may argue that they should have the right to do whatever they want on their own property. Others may also think that the use of a cell phone jammer in public places such as a movie theater or classroom should be allowed to regulate the overuse of cell phones and the interference they can cause. Regardless of any opinion to the contrary, the fact remains that it is not only illegal to use a jammer in any way, but it is also illegal to simply possess it.
This issue is relatively under-represented in Canadian court cases, which may mean that courts can create new ways to deal with this issue if it occurs more frequently. Not so long ago, the Radiocommunication Management Committee proposed to publish a series of drafts prohibiting the unauthorized use of Canada`s cell phone jamming laws. The bill was adopted by the executive session of the provincial government and is currently under consideration by the Standing Committee of the Provincial People`s Congress. The enactment of this regulation can regulate the mobile jammer market and clear rules have been established on the opportunities and departments that mobile signal jammers can use. Clearly indicated in cell phone jammers It is prohibited to set up and use public mobile phone signal jammers without permission, such as cell phone signal jammers. The shopkeeper then gave a demonstration and saw that she had screwed the three short black rods one by one into the antenna interface, then pressed the switch, and a green light on the top came on. The shopkeeper asked the journalist to take out his mobile phone. The reporter saw that the cell phone signal had disappeared and that he could not make a call, no matter how he dialed. «It must not be too far from the machine, otherwise it is useless.» The owner recalled that the shielding range of this cell phone jammer machine and wifi Canada does not exceed 10 meters.
The principle of these large machines is the same, but the power is relatively high, and the mobile phone jammer with power can be used. Shield signals within a radius of one kilometer. The reporter noted that there is no manufacturer and no certificate of conformity on the packaging of the cell phone signal jammer. «All this is produced secretly, how can there be manufacturers?» The owner explained that her goods are imported from Guangdong and quality should not be an issue. The reporter then investigated other electronics stores such as Liaoning Road and Weihai Road and found that it is not difficult to buy mobile phone signal jammers, and the price ranges from a few hundred yuan to thousands of yuan. Elliott Hamilton, an analyst at The Strategis Group in Washington, said that in his opinion, the use of cell phone jammers is a simple problem. «A business owner should be able to do what they want to do on their premises,» Hamilton said. «I don`t see anything wrong [with jammers] as long as their signal doesn`t bleed into the public space.» Industry Canada`s Warnes said the three-month comment period will end on July 12 and the government is expected to make a decision on the legality of cell phone jammers by the end of the year. In a position paper released in November, the RABC`s Mobile Communications and Staff Committee partially stated: «Denial of service (particularly emergency service) may have legal effects on service providers, Industry Canada, the disrupted provider and the operator of public places (concert hall, etc.) if perceived damage or loss has occurred, especially in situations where lives could have been lost or were. «There are several other possible articles of the Criminal Code in which this offence can be interpreted if the circumstances of the case so permit. As a result, jammers are prohibited in Canada until contrary legislation is passed.
However, some countries have allowed or proposed to expand the use of jammers. In India, for example, there are provisions for the use of jammers in schools, mosques and theatres if it can be demonstrated that the interference does not extend beyond their walls. For a short time, jammers were also approved for use in theaters and concert halls, but this ended in 2012. The Criminal Code of Canada also prohibits the use of jammer jammers as set out in section 430 and «there is a very high interest in [cell phone jammers],» said David Warnes, senior consultant for Industry Canada. Last month, Hong Kong, a cell-mad city with about six million people and 5.2 million mobile phones, said it was considering using jammer jammers. Don`t let this stuff sell! At 1 p.m. on the 26th, the journalist went to an electronics store on Liaoning Road. When he learned that the reporter wanted to buy Cell Phone And Wifi Jammer Canada, a peddler asked vigilantly. To allay his concerns, the reporter had to falsely pretend that he had opened a gas station for fear that customers would accidentally call their cell phones while refueling, so they wanted to buy a signal jammer. After some research, the street vendor said he could take the reporter to buy, and he drove him to an electronics store. When the reporter explained his intentions, the trader looked under the counter while asking, saying that he operated several brands of signal jammers with prices ranging from 200 yuan to thousands of yuan.
«If you have a small place, you can use this one!» The shopkeeper took out a black palm-sized instrument under the counter. The journalist saw that there were three screw terminals on top of the instrument, labeled GSM, CDMA and CDMA. 3G, etc. According to the owner, the cell phone jammer has three antennas. When you use it, all you have to do is screw the antenna on it. One of the main reasons why the use of these devices is largely frowned upon by authorities in most countries is that they tend to have a greater impact than expected. Even well-intentioned uses, such as blocking mobile phone use in schools, theaters and hospitals, or banning drones from flying over private property, can cause disruption far beyond the intended limits. Aborted 911 calls, drones falling from the sky, and compromised air traffic control are some of the unintended consequences of jammers that have led countries like South Africa and Israel to make these jammers completely illegal. The wireless industry, some wireless experts and officials in the United States, where cell phone jammers are also illegal, said they are concerned that the devices will inevitably interfere with wireless devices used outside the intended range. However, tech companies claim that jammers are now advanced enough to be very accurate and can also be provided with panels to redirect jamming signals that might otherwise be buried outside the intended area.
Manufacturers say jammers can be set to only handle frequencies used by cell phones, so laptops and other wireless devices such as Blackberrys (faulty pagers) would not be affected. The use of secret locations such as certain agencies, schools, etc. must be approved by the Department of Privacy Administration and Radio Management at the provincial and municipal level and above, and must be conducted strictly in accordance with transmission frequency, shielding range, transmission power, Canadian cellular jammer laws and duration of use. etc. If he violates the regulations and does not use it in accordance with the above regulations, if he causes social harm, he will be instructed by the Radio Administration Department to correct it and cause serious consequences, and he may be investigated for his legal liability.
