Do You Agree That Cell Phone Signal Blocker Be Used In Schools?

The educational environment is supposed to be about students learning and teachers teaching and teachers can't teach over a cell phone. If a student is busy on the cell phone they aren't learning.

What is a cell phone signal blocker?

When you use a cell phone blocker, also known as a cell phone jammer, the signals transmitted by the cell phone actually collide with the signals transmitted by the phone jammer. When the two signals collide, the following occurs…

• The phone signals are essentially cancelled out
• The link between the cellular base station and cellular handset is disconnected
• The cell phone user is unable to make or receive phone calls
  

Should we use the cell phone signal blocker at school?

Should the problem that students using mobile phones for cheating should be concerned about? Surely we should be engaging our kids with the technologies that they use outside of school as opposed to “switching them off” at the school gate. Isn’t it better to teach our students the correct usage of the technology – cellphones, etc.

Find Scalable Solution With a BlackBerry Application Development Company

For mobile phone safety issues, scientists in mobile communication through in-depth analysis of the mechanism of using electromagnetic emission technology, through trial and error, and finally found the effective ways of prevent leak and blocking signal, developed cell phone signal jammer successfully. Cell phone jammer, the use of advanced modern digital communication technology and electronic technology, military anti-jamming develops and produces new intelligent digital integrated system, the digital modulation control mode, through wireless technology control area wireless communication equipment normal communication.

Everyone knows in the same position, different indoor, different time may have great changes of mobile phone signal. According to scientists practical experience, it was found that the change of the value 10dbm can reach the highest power, with the minimum power are 10 times, according to the radio signal transmission distances every doubled, 6dbm power decrease in intensity, 10dbm changes and increase must power equipment may increase redundant, double. Otherwise it will cause the intermittent during operation. In the year of the 24 hours of continuous operation circumstance, this kind of circumstance is not allowed on the high requirements, special occasions such as protracted design according to the highest demand commonly when the signal and power redundancy design, high reliability, confidential for ensuring stable, shielding the effective demand is strictly jamming.

Conversely, in general, only quiet civil in a common conditions can make screen area or shielding rate more than 98%, its operation time, generally does not exceed 8 hours of continuous operation, not more than 1,500 hours. Regardless of how changes in the external environment, the cell phone signal bloker does not necessarily ensure signal of every corner of the screen, that is the basic jamming.

Criminals Jam Radios, Phones

An increasing number of criminals are using widely available technology to block police communications, according to police.
The devices — known as jammers — can create dead zones where police radio and cellphone transmissions are disabled.
The cell phone signal jammer can be bought on dozens of websites for between $100 and $200, according to Abbotsford police Const. Ian MacDonald.
The devices can create a communications-free zone up to 200 metres in diameter, which can interfere with police operations such as the execution of search warrants, MacDonald said.
Handheld units can deaden a zone about 20 metres wide, he said.
Most devices illegal
"It's a reality in the policing world," MacDonald said of the new technology.
"Dependent on how many of these ultimately make it to market and ultimately are purchased by consumers, it may become more of a reality for us."
Abbotsford police believe a number of the units are in use in the community, but they have not yet seized any, MacDonald said.
Macdonald said a particular concern is police safety in situations where an officer might be calling for backup or help but cannot communicate with others.
