5G mm wave can be blocked by paper ffs, range doesnt matter if a leaf can block the line of sight. Idk why we can use the low bandwidth long range 900-1200mhz and just use an array of atenna send out multiple channels to increase bandwidth. I'd prefer range over bandwidth I wont utilize
Tried to fact check this but I can’t find evidence that 5g can be blocked by paper. Looks like it’s in 24-28ghz and while it can be blocked with materials the density matters. So maybe like a few books thick of paper but not one sheet?
Note that this demo takes things over 100ghz. So the challenges associated with mmwave (and wigig) are even more.
Good point thx
Was being hyperbolic m8. The human body will block mmwave
Well the spectrum between 900MHz and 1.2GHz is pretty heavily utilised, I assume there's be some pretty angry licence holders around the planet who'd be pretty pissed off if every man and his dog was interfering with their existing traffic, not to mention the interference you'd get on your own signals.
