Oh, did not know that. so 5G also includes a communication protocol ? E.g. could I make 5G work through 2.4 gHz (WiFi frequency, right ? ) and would it work well ? e.g. gigabit speeds thru 2.4 gHz ? I genuinely don't know, don't mean to make a stupid question.
kinda stupid question: (not meaning to sound as an asshole question) Isn't the mmWave part of 5G itself ? Or what would you define as 5G ?
3G/4G/5G are generations of protocols for cellular communication, they can run over many different physical frequencies.
Their standards committees agreed on certain bands of frequencies, some with more capacity than others.
I'm not an RF engineer, but given 5G can operate on frequencies higher and lower than 2.4Ghz, then I don't suppose there's any reason you couldn't if you were hacking up your own transmitters/receivers. A regular phone wouldn't, though, as they don't have 5G radios that can talk on those frequencies (or they've got hardware filters of some kind to ensure that they don't).
