Can you expland about technology sidr of it?. Whats the significant upgrade for end consumers like me?
News 6GHz Spectrum in process to be delicensed for Wifi 6E & 7

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).
