Understand and choose jammers according to specifications from Frod Kelin's blog

Have you considered buying a jammer, but do not understand it? Most people have heard of cell phone jammer, know its function, but not deeply understanding, and even do not understand the specifications of jammers , and don't know how to choose a good jammer. Now we have to explain the specifications of the jammer, so that you can know it better.

First of all, the band frequency is a critical part of the jammer specification. Because the jammer work by affecting the frequency band to destroy the network signal. The most complex is the mobile phone frequency band, because different countries use different phone bands, and there are 2g, 3g and 4g respectively. Here, you only need to know GSM for digital cellular, the 900 MHz and 1800 MHz bands in Europe and Asia, and in the US 800MHz and 1900 MHz bands.

Take the  60501 Portable Whole Mobile Phone WiFi Signal Jammer for example, the frequency band is:

LTE4G,700

725-775MHz

CDMA800

851-894MHz

GSM1900

1920-1990MHz

3G

2110-2170 MHz

WiFi,2.4Ghz

2400-2500 MHz

GPSL1

1570-1580 MHz

This means that it can affect the range of frequency bands. If you still feel puzzled, do not worry, just tell us your country, we will automatically match your local use of the band.

Effective radius range

The effective radius range is the interference distance that can be used with the jammer. The actual interference distance will vary depending on the signal strength and the use position as well as the full charge.

Total output power

The total output power is the actual power (watts) of the radio frequency energy generated by the jammer at its output. The bigger the total output power, the farther the interference range, the better the effect.

Antenna

An antenna is a dedicated transducer that converts a radio frequency field into an exchange or vice versa. Each jamming device has several antennas to send signals. The more the antenna, the stronger the blocking signal. For some devices, the antenna is built in. The jammer is divided into directional and omnidirectional . Most jammers are omnidirectional. Before deciding on what you choose, you need to know the number of each antenna.

Hope that the above explanation can help you understand the specifications of the jammers and help you choose the phone jammers better.
