Sales of commercial miniaturized drones are booming worldwide, and there are almost no restrictions on the private purchase of drones. Cases include illegal videotaping, drug trafficking, delivery of dangerous chemicals, and even terrorist attacks or military confrontations. Government agencies, military secrecy units, judicial supervision places (prisons/detention centers), large-scale event sites, group activity sites, airports/train stations, oil depots, mining areas, hydropower stations, customs and border defense, anti-smuggling and national leaders travel security guards, etc. Strictly prevent the illegal intrusion of drones and prevent terrorist attacks caused by drones. This has brought great urgent demand to DRONE signal jammer.

The main features of small commercial DRONEs include: low flying altitude, slow flying speed and even hovering, and its appearance is very small, which is commonly known as "low, slow and small". Moreover, DRONEs can be released at any time, quickly recovered, and can also fly between buildings at low altitude to avoid obstacles. Therefore, the effective detection and defense of DRONEs has long been a difficult topic worldwide: conventional radar Even if various technical means such as detection, optical detection, and wireless spectrum analysis are combined, they cannot achieve 100% effective discovery and identification of DRONE targets. It is often when the drone has already approached the target that it panics and thinks of looking for the drone signal jammer.

At present, the mainstream means of countering DRONEs is to install and use DRONE signal jammers, but previous products are generally large in size, require AC power supply and fixed installation, and cannot be used mobile. Even though there are some hand-held or portable DRONE signal jammers, they are still large in size and heavy in weight, making it inconvenient for users to carry them around and use them lightly.

The original intention of the functional design of the handheld drone signal jammer is to use the device directly and quickly to interfere with the discovered drones, and you can choose to "force land" or "drive away" the drones. This working mode is used as the last means of self-defense for close defense against drone attacks. The handheld structure design is convenient for security personnel to carry and put into use quickly. This will be the last line of defense for customers against drone defenses.

Such portable drone jamming equipment is required for security protection when important people travel, large-scale event sites, group gathering places, military secret units, important institutions and patrols of border posts, etc.
