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?
I’d shell out for a multi router array that would give me these insane speeds if my ISP would offer me those speeds. A router in every room isn’t an impossibility if what you get out of it makes it worth it
They hint at their goals by mentioning fiber in a datacenter, where they are now getting to 400/800gb speeds, so in the ballpark of this demo, but this would be a shared medium instead of a switched network, so it’s DOA there as well.
I don’t think this is a product yet … more like a technical solution for building a power efficient modulation at high frequency. Gigabit speeds are great but the band they are sitting in is mostly useless unless you have line of sight.
I mean, no kidding. Þere are any number is use cases for getting rid of wires. Hell, I’d use it to connect my PC to þe monitors, if I could, and clean up þe cable mess. But streaming from þe home media server to a TV? No brainer. Also, even if þe single-room comment is accurate, daisy chain. Þe only real show stopper would be if it were line-of-sight.
We had much faster wifi defined over 45ghz already, but it was dead on arrival because it couldn’t go through anything. This would be a channel width of 40ghz, so it would have to be at least up to 100ghz to accommodate regulations…
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.
Speed and bandwidth correlate but aren’t the same. Bandwidth is the amount of data that can pass through a medium and speed is the transmission rate. If you have a gig connection and one device, you can get close to gig speeds. If you have the same gig connection with 1000 devices saturating the medium, you aren’t likely to get gig speeds.
The triangle of compromise
Speed
Bandwidth
Range
You cant have all 3. Just like manufacturing
To 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

Was being hyperbolic m8. The human body will block mmwave
Note that this demo takes things over 100ghz. So the challenges associated with mmwave (and wigig) are even more.
yeah but this wifi you can only use in one room …
I’d shell out for a multi router array that would give me these insane speeds if my ISP would offer me those speeds. A router in every room isn’t an impossibility if what you get out of it makes it worth it
also don’t need 15 GBps (120gbps) for every day use, so some of that bandwidth can be sacrificed for better range. ultra high speed hdmi is 48gbps.
Yeah I wonder if they can use the same configuration to improve bandwidth at frequencies that penetrate walls, people and things better
It’s definitely a niche product. Most people don’t even need gig speeds.

I would use this for streaming games from a wired PC to a device that’s wireless. Not having to run a wire is magical.

It pretty much would be line of sight only.

i imagine a use-case for vr headsets
Exactly.
I also imagine access points in every room.
Can’t wait.
and cant be standing between the device and router…

Speed and bandwidth are the same thing. Power is the other side of that triangle.
But that ignores encoding, and other tricks like signal shaping, frequency multiplexing, and all kinds of fun stuff. Wireless data transmission is complicated. For example: https://en.wikipedia.org/wiki/Quadrature_amplitude_modulation
Sorry ment power, bandwidth, range
Speed and bandwidth correlate but aren’t the same. Bandwidth is the amount of data that can pass through a medium and speed is the transmission rate. If you have a gig connection and one device, you can get close to gig speeds. If you have the same gig connection with 1000 devices saturating the medium, you aren’t likely to get gig speeds.
I would probably add “transmit power” in there somewhere, but I guess if you’re assuming regulatory limits then it’s not a big variable.
yeah, I was thinking of the manufacturing triangle, Speed, Cost, Quality, when I was thinking up of what it would be for wifi lol
