In terms of radio-wave reconnaissance, offense, and defense, things were actually nowhere near as mysterious as television and movies made them seem.
In reality, there would be no scene where reconnaissance personnel from both sides anxiously hammered away at code in front of their screens, only to gradually lose the signal because of a tiny oversight.
Nor would there be scenes like those in The Matrix, with both sides trading blows and clashing fiercely like hackers.
Those scenes were basically fabricated for the sake of the plot. Real jamming and anti-jamming were actually very simple.
Based on the simple application of technical principles, strategies for jamming and anti-jamming at the radio-wave level often followed the principle of "overwhelming force."
As the saying went, "An official one rank higher can crush a man to death."
At the microscopic level of radio waves, stronger signals could often easily suppress weaker ones.
Take the jammers used in examination halls, for example. Their operating principle was precisely this kind of forceful suppression.
The jammer emitted electromagnetic signals at specific frequencies, covering and drowning out the frequency bands used by mobile communications. This prevented mobile devices from properly receiving external signals and thus achieved the jamming effect.
Generally speaking, at the military level, there were two direct ways to achieve jamming.
One was technical suppression, similar to an enhanced version of an examination-hall jammer. It directly used an ultra-high-powered frequency band to cover the opponent's frequency band, so that no matter what electromagnetic waves the opponent's transmitting equipment sent, all its energy would be consumed the instant they appeared, making transmission impossible.
The other was to release a massive number of interference signals and create a chaotic electromagnetic environment.
Of course, this was a method that killed a thousand enemies while injuring a thousand of
