Can you expland about technology sidr of it?. Whats the significant upgrade for end consumers like me?

Multiple benefits.

6Ghz:
- Frequency range of 5925-6425Mhz (~500Mhz) available.
This is huge compared to the non-DFS 5150-5330Mhz (170Mhz) / 5735-5875Mhz (150Mhz) of 5ghz, or 2401-2483Mhz (~80Mhz) of 2.4Ghz.
Larger frequency range == Wider channels / More channels for different APs to avoid clashes.
Wider channels == More throughput.
Less Clashes == Better everything.
- 6Ghz does not have restrictions like 5Ghz with DFS.
DFS is extremely annoying and slows down connections by 1 minute to 10 minutes depending on the bands used due to beacon scanning.
Also, AP has to move clients over as soon as it encounters a DFS signal. Moving over introduces jitter and can drop packets (since the AP has to scan for available bands before switching clients over, to check whether those bands have a DFS clash as well or not).

WiFi 7:
- Can use 2.4Ghz, 5Ghz and 6Ghz together, instead of separately. More throughput.
- Can also do simultaneous sending and receiving of data. Essentially full duplex like Ethernet (although not true full duplex). WiFi 6E and below are half-duplex.
- If there is congestion, or there's a DFS hit in 5Ghz, the client can instantly move over to a different band. Much lower latency. No dropped connections.
- Also enables better use of 5Ghz DFS bands as the slowdown can be mitigated because of the point above (not sure by how much though). With DFS 5Ghz bands + 6Ghz bands, due to MLO aggregation, you can now have a humongous ~1Ghz wide contiguous frequency range available to you (although I'll still recommend not using DFS channels).

Do we see better teams call and online gaming?

I hope this will push for wired networking to be phased out completely, and be replaced by clutter-free wireless networks. The more we bathe in EMF radiation, the better we will be able to collaborate with each other and arrive quickly at a cure for cancer!

I was just wondering about that. Constant bluetooth, NFC, WiFi in our environment...

Depends on your deployment. It will either remain as good as it is if it's already optimal, or improve if it's not.

Don't.
This is all non-ionizing radiation. It harms you as much as visible light does. Infact, visible light is closer to ionizing radiation on the spectrum than these radio waves. So if these are harmful, then light is much more.

And I don't know about you, but so far I've heard light hurting only one specific type of creatures. Vampires.

Oh and you know what else emits EMF radiation? Electricity wires. Yes, the same ones in our walls and on the streets.

So tldr: Non-ionizing radiation like wifi, 4g, 5g, bluetooth, AM, FM etc is of no practical concern. Has never been.
