Choose the jammers according to specification
Have you thought of buying a jammer but don't you get it? Most people have heard about cell phone jammer, know its function but not deep understanding, and even don't understand the specifications of jammer, and don't know how to choose a good jammer. Now we need to explain the specifications of the jammer so that you can know better.
First, band frequency is a critical part of the Jammer specification. Because the jammer works 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 cell, the 900MHz and 1800MHz bands in Europe and Asia and in the US 800MHz and 1900MHz bands.
Take for example a cell phone signal jammer six antennas, the frequency band is:
CDMA 850-894MHz
GSM 925-960MHz
DCS 1805 -1880MHz
UMTS (3G) 2110 - 2170MHz
LTE network (4G) 725 - 785 MHz and 2620 - 2690 MHz
This means it can affect the range of frequency bands. If you still feel confused, don't worry, just tell us your country, we will automatically match your local usage of the band.
Effective radius range
The effective radius range is the interference distance that can be used with the jammer. Actual interference distance will vary depending on signal strength and usage position and full charge.
overall performance
Total output power is the actual power (watts) of radio frequency energy produced by the jammer at its output. The greater the total power, the wider 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 disorder has multiple antennas to broadcast signals. The more the antenna, the stronger the blocking signal. The antenna is built into some devices. The jammer is divided into directional and omnidirectional. Most jammers are omnidirectional. Before deciding what to choose, you need to know the number of each antenna.
Hope the above explanation can help you understand the specifications of the jammer and you buy jammer.
