How to Choose a Cell Phone Jammer by Specifications?

Posted on 5th Jul 2016 @ 10:27 AM

Are you considering buying a cell Phone Jammer but hesitating for few knowledge of cell Phone Jammers? Most people have ever heard of cell phone jammer, but get no ideas of the specifications of a cell phone jammer. Many of them can’t provide enough information, when they are asking sellers for service. Here are some detail descriptions of the specifications of a cell phone jammer.

Bands frequency

Bands frequency is a key part of cell phone specifications. The supported frequency bands determine whether a certain mobile phone is compatible with a certain network carrier. Although different cellular systems process signals differently, all cell-phone networks use radio signals that can be interrupted. GSM, used in digital cellular and PCS-based systems, operates in the 900-MHz and 1800-MHz bands in Europe and Asia and in the 1900-MHz (sometimes referred to as 1.9-GHz) band in the United States. As a cell phone user drives down the street, the signal is handed from tower to tower. A cell phone jammer works to break the signal of network by affecting the frequency bands.

Take the 40W Power 3G 4G Cell Phone Signal Jammer & WiFi Blocker as an example，bands frequency as:

-CDMA 851-894MHz

    -GSM 925-960MHz

    -DCS 1805-1880MHz

    -PCS 1920-1990MHz

    -3G 2110-2170MHz

    -4G1 2300-2400MHz or 2550-2690MHz

    -4G2 725-770MHz or 790-826MHz

    -WiFi 2400-2500MHz

It means the range bands frequency it can affect. For CDMA , the device can affect bands frequency from  851 MHz to 894MHz. Certainly, it can be customize to decide what rang of bands frequency at your request.

Effective radius range

Effective radius range is the jamming distances it can blocK. The actual jamming distance will be varied depending on the signal strength and the use location and if full charges, etc. For this 40W Power 3G 4G Cell Phone Signal Jammer & WiFi Blocker, its max distance is 50 meters.

Total output power

Total output power,is the actual amount of power (in watts ) of radio frequency (RF) energy that a transmitter produces at its output. For this 40W Power 3G 4G Cell Phone Signal Jammer & WiFi Blocker, its total output power is 40W, Which is high enough to work well.

Antennas

An antenna is a specialized transducer that converts radio-frequency (RF) fields into alternating current (AC) or vice-versa. Every jamming device has several antennas to send the signal. The more antennas, the stronger the blocking signal. On some devices, antennas are external to provide longer range. Jammers are divide into directional jammers and omni directional jammers. You need to know how many antennas of each before you are decide a jammer. For 40W Power 3G 4G Cell Phone Signal Jammer & WiFi Blocker, omni directional antennas all the TX frequency covered down link only.

Hoping the above information will help you get a better choice for cell phone jammer.
