Why does Boss need signal jammers that can block cell phone and WIFI signals? Jammers with Directional antenna or omnidirectional antenna?

We have to admit that in the modern information age, smart phones and the Internet have indeed brought us infinite convenience. However, have you ever thought that apart from the convenience brought by smartphones and WIFI networks, they also cause many bosses to worry?

1. Cell phones and Wi-Fi distract employees

I believe that most bosses are already aware of this problem. Employees are less focused on work as part of their attention is spent constantly checking their phones for text messages or social media feeds. As a result, employees are less productive to a great extent and may even make serious mistakes.

2. Sudden phone ringing interrupts an important meeting

Important meetings are often interrupted by less important activity on employee mobile phones, such as sudden phone rings, because the phone is always on. It's annoying.

3. Mobile phone distraction may cause work-related injuries

This is especially true for shop floor workers. Workers using their phones while working on a production line can be seriously injured as multitasking and carelessness tend to screw things up.

4. Possible disclosure of confidential information

Employees might use a mix of personal and professional apps on one phone, or they might have very private conversations in public places. As a result, the company's confidential information was leaked, resulting in heavy losses.

What measures should be taken to avoid the disadvantages of mobile phones?

Powerful Mobile phone and WiFi signal jammers

To prevent these problems from happening, cell phone cellular frequencies and WiFi networks should be cut off - cell phone jammers will be very helpful for bosses to get rid of them. Mobile phone and WiFi signal jammers can be installed in offices, conference rooms, workshops and other places to allow employees to focus more on their work and improve work efficiency.

Which antenna of the signal jammers is the company suitable for installing? directional or omnidirectional antenna?

The so-called omnidirectional antenna refers to an antenna that radiates and receives in a horizontal plane without a maximum direction. Since both radiation and reception are non-directional, this kind of antenna is more convenient to install, and there is no need to consider the antenna installation angle technology of the transmitting point. Omnidirectional antennas are generally used for jammers with short distances and large coverage areas. They are cheap and have a gain of less than 9dB. The radiation range of the omnidirectional antenna is more like the outline of an apple.

Directional antennas are generally used in signal jammers to shield environments with long distances of signal transmission, small coverage areas, and high target density. The main radiation range of a directional antenna is like an irregular cone (or horn). We can also refer to the relationship between omnidirectional antennas and directional antennas in this way. The omnidirectional antenna transmits signals in all directions and can receive signals from front, back, left, and right. A directional antenna is like having a bowl-shaped reflective surface covering the back of the antenna. The signal can only be transmitted to the front, and the signal transmitted to the back is blocked by the reflective surface and reflected to the front, which strengthens the signal strength in the front.

From the above we can see that during use, the signal jammer is usually installed in the front and back of the meeting room, workshop or office, and the direction is more targeted. Therefore, when choosing a jammer in the meeting room, a directional antenna can be used, and the concentrated interference in the front direction increases the interference distance. Of course, if you need to radiate the surrounding signal around the installation point, you can choose an omnidirectional antenna jammer.
