The triangle of compromise
~~Speed~~ Power
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
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.
yeah but this wifi you can only use in one room ..
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
Wireless 4k 120hz streaming from my PC to TV would be pretty sweet. I can run a cable if i really wanted... but this would be easier. It's still more than that, but getting that would be sweet.
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.
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.
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
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.
