Mesh modems turn Shaheds into FPV drones: how enemy technology works
Russia is actively implementing the technology of remote control of long-range drones via mesh networks, in particular in the "Shahedi".
Russia is actively implementing the technology of remote control of long-range drones via mesh networks, in particular in the "Shahedi".
How it works was told to Defense Express by radio technology specialist, military engineer and engineer Serhiy "Flash" Bezkrestnov.
At Russia's request, Chinese manufacturers have begun mass-producing mesh modems. Although they are labeled as Wi-Fi equipment, they are a completely different technology with a range of 1300-1500 MHz, have an output power of 10 W on two channels, or 20 W on two, and can provide communication over a distance of 100 km or even more. The cost of one such modem is $7,000.
The modems provide encrypted, EW-resistant communications using RF-based RF technology. Each modem on a drone acts as a repeater, allowing all drones to form a single mesh network. This means that even if up to 80% of the Shaheds are shot down, information will continue to be transmitted through the surviving drones.
Initially, the enemy tested this technology for a year on Gerber foam drones. After they realized that it worked, they began installing mesh modems on the Shaheds for online control directly from the territory of the Russian Federation.
The speed of information transfer in a mesh network depends on the range and operation of electronic warfare equipment, and can be up to 50 MB/s, with a worst-case scenario of 2 MB/s.
Although the flight characteristics of the Shahed itself do not allow for sharp maneuvers, the available capabilities are quite sufficient for attacking, for example, moving trains.
Serhiy "Flash" noted that these modems can be turned on immediately before the strike. In addition, we can also talk about ground repeaters. With the help of its own agents, the enemy can quite create ground points with modems that will be connected to the Internet.
"In any case, it is possible to combat such "Shaheds" with a mesh network using electronic warfare means. I have conducted research and a significant number of practical experiments, on the basis of which recommendations were formed for the Defense Forces of Ukraine, which allow us to counteract this threat," the military expert added.
The Armed Forces of Ukraine estimated the effectiveness of electronic warfare against "shaheeds" at 60–70%
