representative bits and rhythm — a web page can't read your phone's radios. real traffic is modulated onto the wave (tap “wave → data” to see how) and encrypted. the point is the emission is always there, going out in every direction.

Wave → Data
Type anything. It becomes bits — 1s and 0s. Then watch a plain carrier wave get bent into shape to carry those bits through the air. The glowing dot is the transmitter; follow it and you're reading the data the way a receiver does.

■ DATA — the bits1 = high · 0 = low
∿ CARRIER — a plain radio wave, carrying nothing yet
∿ MODULATED — the carrier bent to carry the bitsphase-shift keying
In these simple schemes one wave-segment (a “symbol”) carries exactly one bit. Real Wi-Fi and 4G/5G use QAM, which turns the amplitude and phase knobs at once so a single symbol carries 4, 6, 8 or more bits — that’s how you get megabits per second out of the same air. And hexadecimal is just shorthand: each hex digit stands for 4 bits, written that way so humans don’t go cross-eyed. The wire — or the air — only ever carries the modulated wave.
