Home network cabling with POE access points

The Nano HD is better on 5 GHz but the Pro is better in the 2.4 GHz range. Not all devices support 5 GHz, so it's best to check if the majority of your devices can use 5 GHz

Devices that do not support 5 GHz usually do not require high speeds. Where it matters, smartphone, laptop,... you should fully rely on 5 GHz.

Then just take the HD like me ;)
Then you have enough power at both frequencies.
It's best to plan so that in the areas where you spend the most time or always need a fast connection, there is always sufficient 5GHz coverage.
It’s more like vacuum robots, wearables, etc. that can only do 2.4GHz. Everything else runs on 5GHz.

Not every laptop can do 5 GHz :D But 90% of the time you should prefer 5 GHz, you just have to keep in mind that the range of 5 GHz is not as far as 2.4

The HD for 285,- is really excessive for a private household.

Therefore, plan properly with the 5 kHz coverage. Laptop without 5Ghz??? With Win 3.1 on it? So in the last 5 years, everyone should be able to do 5ghz.

I did say it was a bit overkill. That's why in the new house it will mostly be NanoHDs.
We use almost exclusively 5GHz, so the lower throughput at 2.4GHz is not relevant for us.
Overall, our new network is designed very generously (10Gb router, etc.)

When we renewed the network at my parents' place, the Nano wasn't available yet. That's why they have HDs everywhere.
Exactly the same with us in the current apartment.
