At present, each of the mainstream network jammer is a relatively independent device, which is composed of a device host and an antenna. However, some customers find that there is another type of network jammer that can sometimes be found on the market. Its structure is relatively complex, usually consisting of a high-power host connected to multiple antennas through RF feeders. The terminal, these several antennas, are separated from each other by a distance of 10-20 meters. That is to say, this kind of network jammer uses indoor signal distribution to achieve signal interference, so is this method good? What are the pros and cons of this?

First of all, we believe that this is a more traditional solution to indoor signal interference, and relatively speaking, it is also an outdated technical means. Why do you say that? Because of the existing technology, the network jammer can be completely miniaturized, the host and antenna can be built in a small device, and the signal generation and transmission process can be completed independently. For the needs of signal interference in a large area or multiple rooms, it is only necessary to install an independent network jammer in the form of a cellular network. The overall amount of engineering is relatively simple, and the amount of construction is not large. Usually, only the layout of the power supply line of the equipment needs to be completed.

However, if it is the way of indoor signal distribution, then the radio frequency feeder drawn from the network jammer host needs to go through the construction process such as passing through the wall, drilling holes, etc. before it can be extended to each room position, which will cause the installation of the network jammer. to the great difficulty of construction.

In addition, if the network jammer adopts the method of indoor signal distribution, the radio frequency signals of various frequency bands in the main unit need to be combined by the combiner, and then transmitted through a radio frequency feeder, so it is inevitable There are the problems of frequency mixing and signal attenuation, and because the distance of each antenna terminal is different, this will also cause the signal strength received by each antenna terminal to be inconsistent.

Because the frequency range covered by current network jammer is generally from 700MHz to 5800MHz, such a wide frequency range has very high requirements for the technical indicators of the antenna terminal, and if such a network jammer uses a broadband antenna, its The gain value of the antenna will again be very low.

Therefore, based on the above viewpoints, the network jammer that adopts the indoor signal distribution method has many shortcomings and belongs to the technical product that is gradually eliminated.
