The technology to implement wireless is very complex.
However most of the technology is embedded at the chip level.
The users never see the complexity. For the users its plug and play.
From an electronics designers point of view. I am a EE I should have
made a disclaimer up front.

But it is true, that the construction of said complex chips has been worked
on, until the level of reliability is quite high, correct?
