Specialists from PAO Rosseti Centre have developed and patented a portable electronic warfare device for wireless communication, designed as a backpack. The system combines noise signal generators, a power supply, cooling, and an external antenna system, allowing one operator to carry the equipment and quickly deploy a radio jamming zone.
The new development is designed to create broadband radio interference and protect objects from wireless control and data transmission channels. Among the possible tasks of the system are suppressing radio channels of unmanned aerial systems, as well as various devices using mobile communication and wireless access standards.
The device is based on a rectangular backpack-type body made of lightweight plastic. Inside are noise signal generators, cooling radiators, a power supply module, and switching equipment. An antenna-feeder device, connected to the generators by high-frequency cables, is installed on the outside.
In the declared configuration, the system is equipped with ten noise signal generators, but the design allows for placing from one to twelve such modules depending on the required operating ranges. The body dimensions are 500×350×140 mm.
Interference is generated by linearly varying voltage generators and high-frequency generators with controlled voltage. The generated signal passes through amplification stages and is then transmitted to the antenna system.
The developers have provided for operation in several frequency ranges simultaneously. One of the execution options provides signal suppression in the bands 400–1300 MHz, 2300–2500 MHz, 5100–5300 MHz, and 5700–5900 MHz.
To maintain stable operation under high load, the device received a cooling system with an aluminum radiator and fans. All main elements are fixed inside the body on a single base, which increases the stability of the structure during transport.
