Mesh networked Wifi APs should use a separate simultaneous channel for the backhaul, but it doesn’t seem today’s mesh networked APs do that yet.
The ideal mesh networked Wifi AP should:
- not use 2.4 GHz to users due to very limited bandwidth and heavy utilization on 2.4 GHz.
- use 60 GHz backhaul (with large, steerable antenna gain, yes it can work)
- have a graphical interface that encourages users to reduce number of hops by tweaking AP location
- with modern filters, the DFS channels “in between” the 5.2 GHz and 5.8 GHz channels are another possibility
In general Wifi APs should:
- be placed in inner rooms or the inner side of rooms away from windows.
- use wired, MoCA or powerline Ethernet connections to each AP.
Wifi APs should be placed (from most preferable to least preferable)
- in each high usage room (den, kitchen, bedroom), and place a Wifi AP at least every other room for large homes
- in smaller homes, one Wifi AP per home level, near the center of each level
5 GHz on all APs, enable 2.4 GHz only on ONE most central AP to account for IoT devices without 5 GHz.
Wifi AP Performance Notes
- We should always strive for wired Ethernet connections or MoCA to each AP as today’s best HomePlug and G.hn MIMO powerline Ethernet are much closer to 100 Mbps throughput instead of the 1000 Mbps displayed prominently on the package.
- Keep in mind the latency introduced by mesh networking and its impact on the Skype/Facetime video chats.
- Wifi repeaters are even worse w.r.t. latency.
