Why is radio frequency important?（3）

From this perspective, electromagnetic radiation is a good wireless extension of telecommunications used in wired circuits. Whether we like it or not, current and voltage that change over time will produce electromagnetic radiation EMR, which is an accurate representation of the AC component of the original signal. As shown below

This controllable electromagnetic radiation is extremely sensitive and powerful. Even the complex high-frequency waveforms used in the most advanced wireless systems, the transmitted RF signals can be faithfully reproduced. Moreover, this electromagnetic wave travels extremely fast, propagating at the speed of light. If you use another signal carrier, the propagation speed may be greatly reduced.

in addition to the fast propagation speed, the propagation distance of electromagnetic radiation is also considerable. The pursuit of wireless communication is closely related to the pursuit of long-distance communication; if the transmitter and receiver are very close, it is usually simpler and more cost-effective to use wires. Although according to the inverse square law, the strength of the RF signal will be reduced, the combination of EMR with modulation techniques and complex receiver circuits still has a significant ability to transmit usable signals over long distances.

The more amazing thing is that the propagation of electromagnetic waves in the radio frequency band can also penetrate walls, plastic media and other things used in daily life. Unlike light, it can only propagate at line-of-sight. Its application also has great flexibility. Moreover, some low-frequency electromagnetic radiation is almost everywhere.
