Through life, I found many things that appeared to be a good idea but they weren't. Sega 32x, Zip drives, Domestic ISDN, those sort of things. I think 5g is one of those things. When it rains heavily, the signal weakens a lot. The signal is usually so weak that it can't be penetrate into people's homes. I think they would need antennas on every street to let it work properly. When 5g doesn't work, you're automatically switched to 4g an older heavily congested internet. I think even trees can disrupt the signal.
I think the best internet we had for cost was Digital Subscriber Line, the advanced version: ADSL, advanced digital subscriber line; they just used used the spare phone line cable in homes with a filter to get broadband. I like fiber optic internet, we recently switched to full fiber, the cable is so thin yet it carries so much data.
What will they think of next.
