Teacher's cell phone jammer more serious than thought

The science teacher caught using a 3g cell phone jammer in his classroom had hoped to force his students to pay attention, but he ended up putting nearby residents at risk. Cell signals could have been jammed 1 to 2 miles away.

"Something horrible could have happened with that jammer in place people would not have been able to notify 911," said Sheriff Chris Nocco, who says public safety was definitely at risk when science teacher Dean Liptack used the jammer during class.

"It might have interfered with our own 911 radio system so we would have had issues with that, too," said Nocco.

That means the Student Resource Officer's own radios could have been rendered ineffective.

"They are very dangerous because they are indiscriminate when they jam they jam multiple bands," said Joseph Sekula, who is the sheriff's office communications expert.

He says a GPS cell phone jammer can be effective from 50 feet up to 1,000 feet. But Sekula admitted the situation could have been worse.

"Somebody that was a mile or two miles from that Verizon site they probably would not have got in," Sekula said.

Nocco said, "Everybody realizes if something goes on you dial 911 if you don't have the ability to do that bad things can happen."

According to Nocco using a wifi cell phone jammer is not an arrestable offense, but according to Florida Statute you could be facing a first-degree misdemeanor and a $1,000 fine.

But the Federal Communication Commission is not as forgiving, with fines from $16,000 to $112,000 including possible criminal imprisonment for someone caught using a cell phone signal jammer.

cell phone signal jammer is one of the most advanced signal blocking devices that can be found on the internet. It is portable, has a balanced working range and quite impressive battery life.cell phone jammer can work with whole 10 various frequencies simultaneously. It jams mobile phones, GPS and GLONASS navigation, Wi-Fi and Bluetooth connections, CDMA and even 3G networks. We can say that mobile phone jammer is a reliable tool for personal data and privacy protection that won’t let you down at any conditions.

As it was mentioned above cell phone signal blocker perfectly works with mobile phones. It blocks the GSM standard completely, which is using two frequencies: 850/1900 MHz for USA, Canada and Latin America as well as 900/1800 MHz for Europe and Asia. But mobile devices can operate not only those two frequencies. CDMA and 3G are also a really popular data transmission standard for smartphones and other portable gadgets. Jamming CDMA, 3G and GSM will not only give tranquility by blocking the reception of jib-jabbers around you. It will also make you invisible for modern tracking techniques such as cell tower triangulation.

Blocking the GPS and GLONASS frequencies is also meant for tracking prevention. Those global positioning systems are frequently used for these purposes due to a high autonomity of the gadgets used for tracking. Those trackers can live for months because they consume little energy. GPS uses three channels for positioning and their frequencies are: L1 – 1575.42 MHz, L2 – 1227.6 MHz, L5 - 1176.45 MHz and they are totally blocked. GLONASS is broadcasting in two channels: L1 - 1602-1615 MHz, L2 - 1246-1256 MHz and cell phone signal jammer frequency scrambler will also stop it.

Still, Humphreys kept on jamming for another year until two county sheriff deputies pulled him over. They were able to confirm his use of the cellphone jammer before they even searched his vehicle and found it behind a seat cover. As they approached his SUV, their two-way radios were disconnected from their dispatcher.

How exactly can a cellphone jammer shut down service on an entire stretch of the highway? Your mobile phone works by connecting with the service network you pay for via cell towers. They’re scattered everywhere, so that your phone’s signal (or lack thereof) switches from tower to tower as you move about.

  Through
the transmission of a high power signal on the same frequency of a cell phone,
the jamming device creates a competing signal that collides with, and, in
effect, cancels out the cellular signal. Cell phones, which are designed to
increase power in the case of low levels of interference, react to this
interference. Consequently, jamming devices must be aware of any increases in
power by the cellular device and match that power level accordingly.

   As
cellular telephones are full-duplex devices utilizing two separate frequencies
(one for talking, one for listening, where all parties to a call can talk at
the same time as opposed to half-duplex walkie-talkies and CBs), any removal of
one of these frequencies tricks the phone into thinking there is no cellular
service. Consequently, the jammer need only block one of the frequencies. cell

phones work by communicating with a service network through the utilization of
cellular towers or base stations. Individual towers partition cities into small
sections called cells. As a cell phone user traverses the cells in an area, the
signal is passed from tower to tower. mini
