Question about Netgear R9000 Nighthawk X10

Hello RoastedBifi

So far, there are actually no end devices with the 802.11ad standard, as this is basically still under development.
In my opinion, it will not become established in private households anyway, or at least not for a long time yet. The ad standard operates in the 60 GHz range. This has various advantages and disadvantages.

The biggest advantage is that you have much more bandwidth (B) available than with 2.4 and 5 GHz networks. According to the Shannon-Hartley law (C = B * log2(1 + signal/noise), you also have more capacity (C) because it depends linearly on each other.

However, at higher frequencies you also have more noise, which leads to a worse signal/noise ratio. Furthermore, the reflections are also higher at higher frequencies (i.e. objects such as people, walls, furniture, etc. interfere more).

In practice, this means that with 60 GHz WLAN in the vicinity of the router, you have very high data throughput rates, but reception deteriorates more and more with increasing distance (because it decreases quadratically). For example, you can receive the WLAN in the living room (if the router is there) and have very fast connections, but when the doors are closed, you have practically no or only very poor reception in the bedroom. Very few people want that at home.

This approach can be very interesting for companies. For example, in an open office you have fast Wi-Fi for all employees, but outside the room it can no longer be received, which is good for security.
