If you're required to stay at a workstation to receive lifi, it seems vastly better to just connect via ethernet (cat5/6) cable. I don't seem to see what the point of Li-Fi would be
The article mentions 224GBps. I’m sure that’s the theoretical max, but even a small fraction of that would blow away Ethernet. Plus, since you’re not wired, you could move around a room.
You could only move around the room if the entire room is wired for li-fi. If there are other people in the room who need a connection, you're chained to your desk
Sharing airtime will be the same with LiFi as with WiFi. I don't see a reason why moderate movements within a room or even within a building, if short interruptions within door frames are acceptable, should be a problem.
LiFi basically brings a cheap and scaling alternative to fiber glass, which is not widespread as in-office connections (where we are still on RJ45, actually).
Does anyone like connecting an Ethernet cable to their laptop? You could get much faster speeds than with Ethernet with this and not be wired. What’s not to like?
I like wired Ethernet a lot actually. It's got great reliability, low latency, it's highly secure when physical access is controlled and it has powerful features like vlans, port mirroring and power over Ethernet.
The only thing I don't use it for is mobile devices and IoT stuff.
I don't even use a personal laptop really (I hate laptops, I do have about 6 desktops) and my work one is always docked with wired Ethernet.
If I had a dollar every time someone miscapitalized GB/Gb, I would be a lot less angry about people miscapitalizing GB/Gb.
In this case; wow it's actually gigabytes? It does seem strictly theoretical and they mention much more reasonable ~1 gigabyte/s deployments.
>Conclusion [...] scientists and researchers around the world are field-testing LiFi in office and industrial settings and reporting data transmission rates at 1GB per second.
What single device needs to move around in a room (but not outside) and needs even a 10% fraction of 224 Gbps? Maybe something receiving a holographic video in 4K x 4K x 4K resolution?
Look, an infrared remote control for a TV is a pain to use.
You're relieved when that shit is configured and you have a Bluetooth remote in your hand for an Android box or whatever.
If you have to maintain line-of-sight, you might as well drop a cable.
A good use case for Li-Fi might be for a WAN link between two high-rise windows that are across the street from each other, and that's where the bandwidth comes in good as well.
