Cell Phone Jammer Attribute Categories

Cell phones frequency jamming is the disruption of radio signals through use of an over-powered signal in the same frequency range. In the process of interference, the frequency band other than this frequency band will not be affected.

When most people think of frequency jamming, what comes to mind are radio, radar and cell phone jamming. However, any communication that uses radio frequencies can be jammed by a strong radio signal in the same frequency. In this manner, Wi-Fi may be attacked with a network jamming attack, reducing signal quality until it becomes unusable or disconnects occur. With very similar methods, a focused and aimed signal can actually break access point hardware, as with equipment destruction attacks.

Do you ever have a neighbor put a radio on 24h ? Can you ever bear this ? Do you ever have a neighbor play his RC car, plane on there garden all day long with huge noise ? These neighbors are all un-welcome people, they don’t count about other people’s feeling and play on will. Now you don’t have to bear for these things. With a radio frequency cell phone jammer you can easily have their radio frequency down. They will not affect you any more. Stay on enjoying the privacy you deserved. Of course, if you choose the right frequency of cell phone jammer. At the same time, you need to choose the right range of jammer. After all, being too big or too small jammer range may not be as effective as you need.

Mobile networks and carriers in United States use 2 GSM bands, 3 UMTS bands, 12 LTE bands, and 3 CDMA bands. In general, cell phone jammer has more the band, the more kinds of signals that can be disturbed, and the greater the range of jammer.

The cellular jammer band occupies 824–849 MHz and 869–894 MHz ranges. To issue cellular licenses, the FCC divided the U.S. into 734 geographic markets called Cellular Market Areas (CMAs) and divided the 40 MHz of spectrum into two, 20 MHz amounts referred to as channel blocks; channel block A and channel block B. A single license for the A block and the B block were made available in each market. The B block of spectrum was awarded to a local wireline carrier that provided landline telephone service in the CMA. The A block was awarded to non-wireline carriers. In 1986, the FCC allocated an additional 5 MHz of spectrum for each channel block, raising the total amount of spectrum per block to the current total of 25 MHz

It's not the more the better, you have to choose according to your needs. Generally speaking, the more the frequency band, the larger the volume of the jammer, the larger the disturbance range, the less convenient to carry. If you need a portable jammers, choose a handheld blocker. This type of jammer usually has more than three frequencies. If you don't know how to choose, then you can tell us the signal frequency that you need to interfere, and we will recommend the most suitable jamming device for you.
