Mobile Phone Jammer Usage and Maintaining Emergency Contact

Are You Concerned About Using A Mobile Phone Jammer?

 Cell Phone Jammers do not block Emergency Personnel Frequencies!


Are you considering using a mobile phone jammer in your building or your place of business? If so, you are probably curious about how they actually work — and what effect they have on cell phones.

When you use a jammer, a lower power radio signal is broadcast. This signal is capable of cutting off communication between the cell phone and its cellular base stations. When this happens, all the mobile phones in the effected area will show “No Service” — and incoming calls are blocked. To the caller, it simply seems as if the mobile phone is turned off.

Although jamming mobile phones causes them to have no service, certain pre-defined zones are not blocked. By default, these frequency zones include…

*EMS bands

*Fire bands

*Police bands

*Medical services pager bands

Therefore, when you use active jamming, you don’t have to worry about putting yourself or anyone else in danger. Police, fire, and EMS radio users as well as pager users can still communicate, but your customers, patrons, or students won’t be disturbed by non-emergency mobile phone chatter, providing a quiet environment.

Once the jammer is turned off, the phones will automatically reestablish communication with the cellular base stations — and those affected by the jammer will once again be able to receive cellular based services.

It should be noted that using a jammer does not damage phones in any way. It should also be noted that the same situations apply for any GPS jammers as well.

Here is an example situation where a jammer would have been useful:
