# According to reports, Apple will switch to its own iPhone modem design in 2023: Gadgets

Basically, you must consider how to send and receive data wirelessly. Wired communication follows the same logic, but it doesn’t matter. Non-ionizing (harmless) radiation, such as radio waves, which is basically light outside the visible spectrum, is broadcast. When they broadcast it, it is “modulated”, which just means that it is coded. How they encode by fluctuating frequency. When you think of frequency, think of your car FM radio. Channel 107.6 is basically 107.6 MHz (megahertz), which is just a measurement of the wave’s rising and falling speed. 107.6 MHz will go up and down 107,600,000 times per second. But do you see the zeros at the end? This is where it fluctuates slightly; it may be 107,601,500, slightly higher/lower, or anywhere nearby, as long as it does not interfere with the frequency of another channel. These fluctuations are basically codes, just like how dots and dashes are used in Morse code.

The modem can basically interpret these fluctuations in wavelength and determine the code it sends. Then run the code to perform its function (voice, data, etc.). This process is demodulation. The modem can do this in reverse, basically broadcasting the response in the same way.

I know I said I won’t get into the wires, but I’m here anyway. The wires that transmit data do the same thing, but use electricity instead of radiation. .5v is considered 1, and 0v is considered 0. This is where 1s and 0s come from in computer code, kind of. Computers use tiny switches called triggers, which operate in the same way. If the trigger has a voltage, it is 1.

Fiber optics do the same thing, but light passes through glass-like wires instead of electricity.

How much.
