Choose jammers according to specifications

Are you considering buying a jammer but feel unsure about it? Many people have heard of cell phone jammers and understand their basic functions, but they may lack a deeper understanding of the device and have trouble choosing the right one. To help you better, let us explain the specifications of a jammer.

First, the band frequency is an important aspect of a jammer’s specifications. Jammers interfere with network signals by disrupting specific frequency bands. The most complex frequency bands are cell phone bands because different countries use different bands for 2G, 3G, and 4G networks. For example, the GSM band is used for digital cellular networks, Europe and Asia use the 900MHz and 1800MHz bands, while the United States uses the 800MHz and 1900MHz bands.

As an example, let’s consider a jammer with six antennas. Frequency bands may include:

• CDMA: 850-894MHz
• GSM: 925-960MHz
• DCS: 1805-1880MHz
• UMTS (3G): 2110-2170MHz
• LTE networks (4G): 725-785MHz and 2620-2690MHz

These frequency ranges indicate the frequency bands that the jammer can affect. If you are still confused, don’t worry. Just tell us your country and we will automatically match the jammer to the frequency bands commonly used in your location.

Another important specification is the effective radius range. This refers to the distance at which the jammer can effectively interfere with the signal. The actual range may vary depending on factors such as signal strength, location of use, and battery charge level.

Overall performance is determined by the total output power of the jammer, which is measured in watts. This power represents the actual RF energy emitted by the jammer. Generally speaking, the higher the total power, the wider the interference range and the more effective the performance. Best-selling wifi jammers and GPS jammers in Europe and America.

Antennas also play an important role. It is a special transducer that converts RF field into electrical signal or converts electrical signal into RF field. Jammers usually include multiple antennas to transmit signals. The more antennas there are, the stronger the signal blocking ability is. Some devices have built-in antennas. Jammers can be divided into directional jammers and omnidirectional jammers. Most jammers on the market are omnidirectional jammers. In order to make an informed choice, it is important to know the number of antennas before choosing a jammer.

We hope that the above description will help you understand the specifications of the jammer and help you make an informed purchasing decision.
