In today's radio-rich world, ensuring the absolute security of important communications is a very challenging task. The threat of radio eavesdropping and electromagnetic interference is omnipresent, and once confidential information is leaked, the cost will be incalculable. Multi-band selective shielding with its unique ‘directional protection’ ability, is becoming the protection of critical communications tool, to achieve a high degree of precision and efficient electromagnetic shielding.

Comprehensive communication band protection

Different from the traditional signal jammer equipment of full-band shielding, the new generation of multi-band selective shielding in the design concept to achieve a major breakthrough. It can effectively protect most communication bands, including radio, radar, satellite navigation, radio frequency and other bands, covering a wide range, called omnipotent.

This innovation greatly improves the communication security coefficient. Whether it is the most advanced eavesdropping equipment or sophisticated electromagnetic strike weapons, in front of this all-round electromagnetic ‘vacuum zone’, will be completely useless.

Precise ‘directional protection’ at the critical moment.

However, only rely on full-band shielding is far from enough. In many scenarios, communication devices need to use some of the necessary frequency bands, such as Bluetooth, WLAN and so on. If not selective full shielding, it will affect the normal use, so that communication is interrupted.

The uniqueness of multi-band selective shielding is that it can flexibly switch between several modes according to the actual needs of some of the frequency bands for directional protection, without affecting the use of other frequency bands.

This ‘directional protection’ ability to make high power blocker protection becomes extremely accurate and efficient. For example, for classified video conferencing, you can choose to shield only radio, radar, satellite navigation and other frequency bands; and the use of intelligent hardware devices, you can focus on defending against unwanted RF bands, but at the same time to retain the necessary WLAN, Bluetooth and other short-range communications.

Once anomalies occur, it can also be quickly switched to full-band shielding mode, forming an absolute ‘vacuum zone’. This precise, timely, comprehensive ‘directional protection’ ability to ensure smooth communication and absolute security of the organic unity, breathtaking.

Emergency to retain the communication path

In addition to ‘directional protection’, multi-band selective shielding also has another extraordinary ability: even in the case of electromagnetic protection is activated, its unidirectional communication function can also make the key communications remain connected.

This means that in the face of an unexpected crisis, communication devices can continue to send out dispatch or warning signals under the protection of the drone blocker, but at the same time to ensure that sensitive communications are not eavesdropped on or interfered with by those who wish to do so. Reliability and security of communications go hand in hand.

It can be imagined that in some military exercises or special operations and other critical moments, if the use of shielding to effectively protect the instantaneous security of command communications, it is clearly of great strategic significance. In the civil field, similar functions can also be used to maintain order and deal with dangerous situations.

Unprecedented Mobility

Another highlight of the multi-band selective shield is its excellent mobility. Nowadays, portable and vehicle-mounted products have become the mainstream configuration. Through a number of lightweight and portable, rapid formation of the medium, such as backpacks, special operations vehicles or aircraft belly compartments, the ubiquitous electromagnetic barrier is formed.

This highly flexible deployment greatly enhances the tactical utility of the shield. In changing environments, combatants can quickly establish ‘iron barrel positions’ to open up a safe channel for critical communications. Regardless of the battlefield changes drastically, electromagnetic ‘vacuum zone’ will always be with the combat troops.

In the future, ‘directional protection’ will become an inevitable trend in the development of communications UHF VHF signaljammer technology. Multi-band selective shielding will rely on its outstanding accuracy and efficiency, safety and smooth and other advantages, in the military, government, business and other classified areas are widely popular for critical communications to create a safe and efficient ‘fast lane’.In the face of ever-changing radio technology, this emerging communication protection magic weapon will certainly play a more important role in the field of wireless security, for the absolute safety of important information to build an impregnable ‘directional protection’ barrier.
