The advantage of drum signals over smoke signals is that drum signals are faster, and you can transfer more information in the same period of time. The speed of drum signals is limited by how fast you can pound the drums, how fast you can hear the drums and still differentiate them as single beats, and how much multi-path echo distortion you get with drums. The speed of smoke signals is limited to how fast you can modulate the smoke into pulses, allowing them to differentiate into distinct puffs as they slowly rise into the air.
Before the phone, but after the common use of electricity, the most common method of communication quickly across country was the telegram. Before electricity, smoke signals were used, or sometimes signal flags of some kind.

Synchronous demodulation is done using the same modulating signals such as cos(2000t) that was used in the transmitter. It still has to use Band-Pass (if multiple signals are present) and Low-Pass filter

color of the smoke.
Smoke signals were used to communicate with other people from far away when they were in trouble and needed help. Old Indian tribes would have special signals to communicate to there own tribe that was far away. Because anyone could see the smoke signals, the sender and the receiver of the smoke signals had their own special code.
Smoke signals were actually invented in 900 BC. They were first invented in ancient China to protect the Great Wall of China.
