Hello everyone! Those controllers are wireless ones and with pretty large working radius. How can I block their signals?
The United States is a country that is at the forefront of all innovation, be it in the field of technology or security, or any other aspect. Everyone now knows that government agencies in the United States and other developed countries have been able to build advanced instruments, tracking information from smartphones, tablets and various gadgets. The best thing about these modern tools is that the tracking activity is done secretly without informing device users. According to the Wall Street Journal, advanced technology, the dirtbox, is being corrected in tracking aircraft or special aircraft. This instrument has the ability to act as secret towers in secret, without warning users of the truth.
Q2 and Q4 XBee controllers are used for different robots like cars with cameras or hexapods. These controllers are incredibly functional. As for the working range that you have mentioned, it depends from the sensors used inside those controllers. Those sensors are made by Dexter Industries and there are two of them: NXTBee (or XBee) has 100 feet of working range indoors and 300 feet outdoors while NXTBee-PRO has 300 feet of operating area indoors and up to 1 mile outdoors.
Both Q2 and Q4 use one of those sensors so they use WiFi frequency to control the robots. The working power of NXTBee is 1mW (+0dBm) and NXTBee-PRO has 63mW (+18dBm) of operating power. In order to block the work of any robot controlled by those wireless controllers you can use Q2 and Q4 XBee controllers gps jammer that has working power of 270mW (+70dBm) that will definitely do the job.
