5G roadblock: labor

Fri Jan 3 14:05:56 UTC 2020

Correct me if I’m wrong, but I believe that it’s become a wavelength problem at this point with 4G in high-density areas. 5Gs shorter but higher in spectrum wavelength will need more nodes per square kilometer but have a much higher limit to its bandwidth ceiling. I believe the numbers I saw were something along the lines of 10k people per square kilometer for 4G, and 1M people per square kilometer for 5G at the 300GHz wavelength.

In locations with high population densities, there is nothing you can do to LTE to provide adequate service.

Obviously if the technology is available, works well, and is reasonably priced, 5G it up. However, if you're adding small cells every 500', tripling the amount of "towers" you have...  does it matter much if it's LTE or NR? You're adding hundreds of megs if not gigs of capacity with LTE.

Which brings us full circle - what's the cost of hooking those dense
cities up to 5G in 2020 vs. running fibre to an 802.11ac|ax access point
to serve its residents and visitors, in 2020?

And more interestingly, if that city's residents and visitors had the
option of connecting to active 5G or wi-fi, what do we think they'd choose?
