Cell Phone Jammers In Schools

From EjWiki

Some of the functions include radio frequency jammers that prevent wireless spy cams from working to GPS jammers that prevent any GPS trackers from following you to cell phone jammers that stop important meetings from being interrupted by personal calls there is a jammer for every purpose.

Signal jammer will have some difficulties in interfering with other electronic devices which are in good working condition. These jammers are also used and regulated by the government and are usually intended to jam cellular phone communication lines only. Similarly, They only damaged the receiving end of a cellphone call because it directly interferes with the cell phone and the base station itself. It has a relatively small electromagnetic wave and as such, it has no known damage to the human body as well as to the cellular phone itself. However, if the jammers are bigger, like outdoor signal stations there can be health repercussions for such.

Today's kids rely heavily on technology, use it on a daily basis and enjoy using it. If teachers integrated more technology into the classroom like laptops, online lessons, projects that included a lot of use of technology, the kids would be ore interested and be swayed from being distracted to their everyday cell phone because of the new technology they are being shown by their teachers. Bottom line is schools and teachers need to add more technology into the classrooms to keep up with the times and keep the children interested and challenged on a daily basis.

A simple cellular phone signal jammer usually costs around US$ 33-122. GPS jammer is priced between US$ 99 to 1.495 each. The price for Wi-Fi/Bluetooth jammer starts from US$199 while the multi function Wi-Fi and Video jammer starts from US$ 295. This relatively low priced gadget added to its popularity and repeated use.

Even more, Qatar asked for 24 AH-64D Apache Attack Helicopters
which are also in the pipeline for sale. That sale includes nearly 600 Hellfire missiles and 300 stinger missiles, as well as night vision goggles, 60 GPS systems, 30 radio jammers, 30 chain guns, and much more. 

While it can be argued that pen lasers are used for presentations and can do little damage there are lasers out there that can do more than show a spot on the wall. To that respect lasers above a certain mW strength are authorized for government use only and will be seized if caught in the hands of a 'civilian'.

Another more commonly used is the GPS signal jammer. These are commonly used by the military to confuse GPS tracking for locations. Similarly, there are no homemade tracking systems like this. Civilians who make use of these jammers to hide or cover up his location and that of his vehicle should in case it is being tracked by a GPS receiver. A civilian GPS jammer usually covers up to 10 meters only.

While GPS jamming devices are manufactured to be effective against civil use GPS signals only (C/A code) the prevailing sentiment is that use of these devices may interfere with public transportation and military frequencies.

The cellular phone jammer is probably the most common signal jammer available. It disrupts and prevents the cellular phone from receiving signals from its base station, by blocking radio waves. The basic one usually works in a 10 meters to 1 kilometer distance. But those involving outdoor signal stations which are bigger with different base stations and positions can effectively jam the signals of any GSM and CDMA phones.

The GPS earth monitoring stations, of which there are 4 unmanned and 1 master stations, are responsible for relaying position data from the satellites to the master station. The master station uses this data to correct the position of the sat tiles which is then transmitted back to the satellites. This keeps the data that the satellites transmit synchronized to provide accurate coordinate information

A GPS receiver triangulates its position based on the position of at least three satellites. It calculates your position by comparing the time it takes your receiver to receive the signal from each satellite.

With more and more citizens arming themselves against an increasingly intrusive world the demand for video equipment and listening devices as well as personal security items (pepper spray, etc.) is growing daily.

One very big drawback of these devices is that they can interfere with many other batteries operated low voltage devices. One example is a pacemaker. This might get damaged temporarily with a nearby jammer usage and can cause drastic results. Hence, one thing is for sure that even if you are allowed to use this device for convenience, this powerful gadget needs to be used with a lot of care so as not to cause any hazard to anyone.

Have you ever been in a situation or in a location where you feel your mobile signals do not work anymore or even the Bluetooth or Wi-Fi signals on your mobile or laptop has gone dead? Beware; you may be in an area where there are cell phone jammers placed to block your calls.
