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

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?

Ah, memories of using the infrared port on my laptop to share WinAmp skins in 7th grade art class…

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.
