Interesting questions in life: Why are there no signal jammers on airplanes?

What are commonly referred to as signal jammers are actually “signal jammers” or high-power jammers. This distinction is important because it clarifies the purpose and function of these devices. Restrictions on the use of cell phones on aircraft are primarily intended to avoid any interference with aircraft communications caused by cell phone signals. Installing signal “blockers” would introduce a significant source of interference, which is why such devices are not found on aircraft.
