5G roadblock: labor

Fri Jan 3 19:21:16 UTC 2020

Right. I didn't want to spend too much of my time delving into any and all situations where it'll vary. 

I wonder how much the sub 1 GHz penetrates the buildings anyway if the transmitter is at the street. 

5G won't solve the building penetration without entering the building, which 4G could do just as well.

Mike, I'd caution your use of: "other than in the bowels of large 
buildings" there... In office buildings (or residential buildings) 
which are LEED certified often you get glass coatings which reflect 
radio emissions (both reflect IN and reflect OUT) so.. in most 
'modern' office buildings (which LEED certification, or equivalent) 
even standing next to a window you may not pick up LTE/3g from outside 
:( 

there are internal building deployment things, of course, which can be 
done... but not every building is equipped :(
