So wifi is super fast but limited range, just like 5G. And 5G also has a host of other challenges(power consumption). If carriers need to put 5G towers on every street corner just to be effective why can’t they just use wifi tech and put wifi routers on every corner?
In: Technology
may sound a bit complicated but read about waves : [https://www.physics-and-radio-electronics.com/physics/waves.html](https://www.physics-and-radio-electronics.com/physics/waves.html)
waves are created by a machine (in this case the router’s oscillator) and in the case of 5G, the machine required is different/faster/smarter than what you refer to as wifi router. 5G technology needs a completely different infrastructure.
5G=5th generation it has nothing to do with wave frequency (Hz)
