With the continuous development of communication technology, mobile networks have undergone several upgrades, from the initial 2G cellular network to the current 3G, 4G, and even 5G mobile signal networks. Alongside this progress, full band interference devices have also experienced constant updates and advancements. These devices are primarily used in educational institutions for exams, such as the college entrance examination, as well as in venues where the use of mobile phones and other communication devices is prohibited. As the frequency bands of communication networks increase, full band interference devices have evolved from initially having 4 antenna ports to 8, and even more than 12 antenna ports, to the current built-in antenna full band interference devices.
The First Built-in Antenna Full Band Interference Device:
The first built-in antenna full band interference device not only possesses an aesthetically pleasing appearance that aligns with modern aesthetic standards but also eliminates the need to manually attach antennas during usage. In the past, full band interference devices required users to screw on antennas one by one, which was time-consuming and inconvenient. However, with the introduction of the first built-in antenna full band interference device, this issue has been resolved.
The Second Built-in Full Band Interference Device:
The second built-in full band interference device offers even more advantages, such as being environmentally friendly and safer to use. Previously, external full band interference devices with metal casings would generate high temperatures of 50-60 degrees Celsius after prolonged operation, posing certain safety risks. In contrast, the built-in antenna full band interference device is made with a plastic casing, effectively addressing this problem.
As mobile networks continue to evolve, so do the devices used to manage and control them. Full band interference devices have undergone significant advancements, from the number of antenna ports to the introduction of built-in antennas. These devices not only enhance the efficiency of managing communication networks but also provide a safer and more convenient experience for users. With the continuous development of technology, it is expected that full band interference devices will continue to evolve and adapt to the changing needs of the telecommunications industry.
