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

felixwhynot@lemmy.world 1 week agoTo be fair most wifi is used within homes or businesses these days so I would simply sacrifice range — as long as the minimum range is reasonable

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

The issue will be less about “range” and more about being able to go through a wall. Higher frequency makes for shorter radio waves that are closer together. The more this is done, the less it can go through solid objects and still be decipherable.
It’s like a sound wave. That big low frequency bass sound can shake your walls while playing from in your neighbors house. You can’t make out or hear a single word being sung, though. Frequency is too high to make it through to you.
This tech can be nicely used for wireless VR and maybe a couple other things that need to move data at super low latency at a local level, but beyond that, it will be kind of useless for anything over the next decade.
