LiFi, or 802.11bb, isn't really meant to replace Wi-Fi, but complement it—a good thing for a technology theoretically nullified by a sheet of printer paper. In an announcement of the standard's certification by IEEE (spotted on PC Gamer) and on LiFiCO's FAQ page, the LED-based wireless standard is pitched as an alternative for certain use cases. LiFi could be useful when radio frequencies are inhibited or banned, when the security of the connection is paramount, or just whenever you want speed-of-light transfer at the cost of line-of-sight alignment.
Frauenhofer HHI, one of the standard's developers, suggests "classrooms, medical, and industrial scenarios." Operating in the optical spectrum, rather than the limited amount of licensed radio wavelengths, "ensures higher reliability and lower latency and jitter," says Dominic Schulz, lead LiFi developer at Frauenhofer. It also reduces jamming and eavesdropping and enables "centimeter-precision indoor navigation."
Wi-Fi 6E differs from Wi-Fi 6 in that it can use the 6 GHz frequency band, adding 14 more 80 MHz channels and seven extra 160 MHz ones. Those upgrades help fight congestion and target fast speeds for applications like high-definition video streaming. //
In January, MediaTek, which makes Wi-Fi chips, began live demos of Wi-Fi 7. The next-generation tech is expected to support a max theoretical throughput of at least 30Gbps, compared to Wi-Fi 6 and 6E's 9.6Gbps, according to the Wi-Fi Alliance, which makes the specification. Upon conducting its live demos, MediaTek said it expects to have products available in 2023.
I love fussing with wifi, but when I’m building the backbone of my network in a new location—a house, apartment, or wherever—I tend to go wired as much as I can. Wireless bridges and tri-band mesh/extender setups are great and convenient, but I always appreciate the stability and speed of an Ethernet cable. //
When I recently offered to help my friends set up their house with a wired backbone, I came across a fun problem: No Ethernet connections in any of their rooms. //
The ingenious solution to this problem? MoCA, or “Multimedia over Coaxial.” I’ve known about the technology for a long time, but never had the time (or need) to play with it until now. My friends’ house was wired with coaxial cables in every room, which made this an ideal solution. I could just use MoCA instead of Ethernet—MoCA 2.0, technically, which gives up to a full gigabit worth of speed and should be more than adequate //
I got my hands on a two-pack of TrendNET TMO-311C2K adapters and got to work, which took all of five minutes because I was acting the fool. It should come as little surprise that plugging in the MoCA adapters to various coaxial ports around the house achieved absolutely nothing. //
That’s just one big way to say that I wasn’t too surprised to find that many of the coaxial cables around my friends’ house simply weren’t connected to anything. I was eventually able to confirm this by tracing the wires to the outside of the house, where I found where all the disconnected cables terminated. I then went and picked up one of these to test which cable went to which room in the house:

Wi-Fi is like real estate—the secret is location, location, location.
In this guide, I create a separate WiFi interface for phones and tablets.
Phones rarely need full network access to other local devices. And they have a nasty habit of getting lost, stolen or otherwise broken, so having a separate WiFi access point (and password) means you don’t accidentally disclose your main WiFi password.
