New Network Design

[therealdkc]

Hey everyone,

I'm building a new home and thinking about networking. I've been playing around with the Ubiquiti planning tool and wondering if anyone has any good experience with the tool and the brand. Ultimately, my goal is to have efficient coverage to cost ratios. I don't really care about 6 vs 7, but after putting some 6s in place in the tool, it seemed like I could get more efficient coverage with 7. For the basement I have a U7 Pro and for the main and upper I have a U7 LR

Anyone have any thoughts, tips, tricks or anything else they can share? I really appreciate it and happy to document my setup if it helps anyone.

This floor heatmap with a single AP doesn't look right to me unless the house is really built from very RF transparent materials. I don't see the dimensions, but seems like the walls on upper floors don't even exist for Wi-Fi. Are you sure the wall materials selected in planning are close to the real materials used? Otherwise the planning tool is quite accurate when the input data is accurate.

The APs can't be placed one on top of the other on different floors. They will be too close to each other. Must be placed diagonally on different ends of the house. The signal goes through floors as well. If you don't care about Wi-Fi 7 go with known working well Wi-Fi 6 APs. Preferably Qualcomm based hardware, do your research. Set realistic expectations, don't overpay for hardware.

Thanks for the reply Tech9. The basement is about 750sqft, the main floor 1004sqft, and the upper is 1303sqft. All interior walls are 2x4 stud with drywall, save for the stairway which I believe is 2x6. In the planning tool, I drew the interior walls as Drywall. Should I also draw a Wood wall along the same line as well?

Conservative planning is good. Start with 2x APs on the upper floors close to far ends of the house, if possible. I personally like U6-Mesh APs and use them everywhere because they are small, omnidirectional, with good range, high wife acceptance factor and can be placed on a desk or shelf, mounted on a wall or ceiling, even placed outside for outdoor applications. They also have nice RGB ring and it may be important for someone. My wife wants bright white light so they look like light fixtures.

The hardware inside is equivalent to U6-Pro. The specs and real performance are very close. Just different shape and size.

5Ghz will go through 1 wall of studs and drywall. Sometimes, it will penetrate 2 walls but signal will be greatly reduced. It will penetrate 1 floor wood framing, wood flooring. HVAC ducts will block the signal. 2.4 GHz will get through 2 drywall walls. You will eventually have house stuff on/near those walls so the attenuation is higher. Better to reduce the power on the APs and add more APs to the system to get good coverage.

Try placing one AP centrally on the ceiling every other floor. Otherwise too much overlap. Look at the polar plots and the azimuth plots for the AP radios in addition to the heat maps. The plots assume air only environment, but will give you an idea of the shape transmitted by the radio.

More importantly, the client devices likely have weaker radios and will only get through 1 wall or floor.

I have some clients behind two walls with -65dBm signal. Two walls is acceptable for base calculations even without the planning tool, but the angle of the walls relative to the AP is important as well. For this area and based on description I believe 2x APs are good starting point, perhaps 3rd added later on and all on lower power. I personally like all APs the same model and type. I have 4x APs in ~6000sqft house in CA region, but 2x APs in 1800sqft in EU region. So the region is important too.

Quite a bit of threads on SNB Forums about Ubiquiti and other low cost SMB options, actually. From small home setups to larger business sites. Tips and tricks how to make Wi-Fi better with multi-AP system were also shared and discussed. Search around.

Thanks for the responses so far. I will do some added research. I want all the APs to be ceiling mounted and I will use PoE to connect them all so ideally I get the plan sorted out without the need to add down the road. I suppose more APs is the best bet to ensure that happens and I wasn't too sure on the reliability of the planning tool. I also don't have an unlimited budget so AP choice/location is something I'm trying to pay close attention to. I also intend to have 3-4 VLANs and require VPN as well which is primarily what drove me to Ubiquiti. Excited to plan this all out and appreciate everyone's input.

Well... 4x U7-Lite ($99/each) are just a little more expensive than 2x U6-Mesh ($179/each). If you like guaranteed coverage go with more lower price APs and adjust the system in software after. U7-Pro is dual-band, has 2.5GbE uplink port and 2-stream radios with up to 24dBm on 5GHz with 5dBi antennas. I think you'll be swimming in Wi-Fi on full power, you have to reduce it for optimal Tx/Rx links. For switching something like USW-Flex-2.5G-8-PoE ($199) is a good match, it can power 4x U7-Lite and has all 2.5GbE ports + 2x 10GbE for uplink. For gateway the new UCG-Fiber ($279) has the most capable hardware, but UCG-Max ($199) may be good enough. What you get is 2.5GbE wired network and about Gigabit wireless per AP (to Wi-Fi 7 client).

If you have 2x 80MHz non-DFS channels available in your region this system may get close to 2Gbps aggregate throughput on wireless. If you don't need high speed on wireless but prefer less interference and lower latency (like me), dropping channel bandwidth to 40MHz may work good for you and with ~3db better signal to clients (better range). You can do whatever you want configuration with the above setup on wired and wireless, just don't expect stellar VPN speeds from an ARM CPU based hardware. UCG-Max can do about 150Mbps on OpenVPN and 500Mbps on WireGuard, UCG-Fiber perhaps more, but nothing will do 2.5Gbps. For this you need x86 hardware gateway and it won't be cheap and won't be integrated into your UniFi setup.
