UniFi BeaconHD Review: An Excellent yet Frustrating Mesh Add-on

Share what you're reading!

The UniFi AP BeaconHD Wi-Fi MeshPoint (model UDM-B)—a.k.a. BeaconHD or UniFi Dream Machine Beacon—from Ubiquiti, can be an excellent mesh add-on unit or a frustrating one, depending on how many wall sockets and what type you have around your home.

In any case, if you already have the UniFi Dream Machine (UDM) and now move to a larger home, the Beacon can be a viable option to build a robust mesh in a snap. Where its physical design works out, the mesh point is worth the current cost of around $130.

Note: This post only makes sense if you have read my review of the UniFi Dream Machine.

Beacon HD and UDM
Take the UDM’s top and stretch it out, and you get the UniFi AP BeaconHD Wi-Fi MeshPoint.

UDM BeaconHD: A convenient yet potentially problematic mesh point

Out of the box, the UDM Beacon looks like an elongated top of the Dream Machine. It’s a rounded rectangle with a big logo of Ubiquiti on top. Its rim doubles as a color-changing status light, just like the case of the UDM.

This light responds each time you want to apply changes to the Beacon’s setting. When applicable, you can also use it to locate the device or as a night light for a room—it’s quite bright and lovely. And just like the case of the UDM, you can manage the Beacon’s light via the UniFi mobile app.

Convenient plug-in concept

The way it works, you have the Dream Machine router working at a corner, then place the Beacon at a distance, and the two will form a mesh Wi-Fi network.

On the underside of the Beacon, you’ll find an integrated three-prong plug. Snap it into a socket, and you’ve finished the hardware setup. The device fits snuggly. It’s super-fast and convenient.

But the reality can be a bit more complicated.

Beacon HD Underside
The underside of the UDM BeaconHD. Note the groove that causes its three-prong plug to be too short for most wall sockets.

Thoughtless plug design, too large for its own good

That’s because the Beacon is way too bulky. Measuring 6.68-inch (169.7 mm) tall and 4.42-inch (112.5 mm) wide, the add-on mesh point will cover the entire surface of a multi-outlet. That, plus the fact it has no pass-through socket, means wherever you use it, you can’t expect to plug anything else into the power.

That’s if you can plug it in at all. That’s right. You can’t just plug the Beacon into any wall socket. Its prongs don’t stick out from a flush surface but a groove that’s about a quarter of an inch deep and half an inch narrower than the unit itself, in anticipation of a faceplate’s protruding top.

As a result, you can only plug it into a single socket or a two-outlet wall faceplate. If you have a 3-outlet or a larger one, the Beacon’s plug is too short for the device to get juiced up or stay put.

Consequently, it’s also very awkward when used on a power strip. You will need to plug it into a socket at the end of the trip for it to stay put and get connected. Even then, the Beacon will probably still hog the entire power strip for itself.

Also, in this case, you don’t want to leave it on the floor—you’ll trip over it, plus that’s not good for the Wi-Fi signal. But if you hang it up, the whole thing is an eyesore.

I had a hard time finding the right place to leave the BeaconHD during my testing and sorely missed the compact design of the AmpliFi HD’s mesh point.

UDM BeaconHD: Hardware specifications

As the name suggests, the UniFi Dream Machine BeaconHD aims to be an add-on mesh point specifically for the Dream Machine router. However, as part of Ubiquiti’s UniFi hardware product line, it will work with any UniFi controller.

By the same token, it will not work with an AmpliFi router, like the AmpliFi HD mentioned above. And the Beacon doesn’t work with any third-party router.

Dual-band top-tier Wi-Fi 5 specs

At the core, the UniFi AP BeaconHD Wi-Fi MeshPoint is a 4×4 Wi-Fi 5 extender with the top speeds on the 5GHz of 1733 Mbps. It’s a dual-band device, so there’s no dedicated backhaul. As a result, at best, a client will get just 867 Mbps out of it due to signal loss.

It’s always tricky to find that sweet spot to place a wireless mesh point, especially one without a dedicated backhaul band. Too close, and you don’t have the coverage you want. Too far, well, there’s not much signal from the router for the device to extend.

In the case of the UDM BeaconHD, things were much harder. You have to be quite lucky to have an available and suitable wall socket at the perfect spot.

In most cases, you’ll have difficulty finding a place to plug in the UDM BeaconHD.

UDM BeaconHD: No-brainer setup

But that’s the only issue with the Beason. Once you have found a place for it, the rest is a no-brainer.

The setup process is super easy. Just plug it in a few feet from the Dream Machine router, and run the UniFi mobile app. Within a few seconds, you’ll see the AP BeaconHD appear on the Device tab as “Pending Adoption.”

Now, tap on it, and the system will add it to the Deam Machine’s UniFi controller. The whole process took me less than a few minutes. After that, I could change the name of the Beacon and use the mobile app to manage it, including viewing connected clients and a host of other geeky information.

By the way, while the setup was easy, I did notice some minor oddities. The mobile app doesn’t allow for firmware updates. For that, you’ll need to use the web interface of the Dream Machine. In my testing, the Beacon worked much better with the latest firmware, which is generally the case with most hardware—make sure you update it right away.

Once everything is up and running, just like any other mesh system, clients connected to the Beacon will enjoy all the settings and features of the Dream Machine itself. Among other things, that means the mesh has much more to offer than an AmpliFi HD set.

Beacon HD Setup
Setting up the UDM BeaconHD is a breeze via the UniFi mobile app.

UDM BeaconHD: Excellent performance

I stacked the UniFi AP BeaconHD Wi-Fi MeshPoint up against satellite units of other Wi-Fi 5 mesh systems, and it did very well for a dual-band broadcaster.

Specifically, at a close distance of fewer than 10 feet (3 m), my 3×3 Wi-Fi 5 clients were able to get a sustained speed of 314 Mbps out of it. When I increased the distance to 40 feet (12 m), it averaged 242 Mbps, faster than the tri-band Netgear Orbi RBK50.

UniFi AP BeaconHD Wi Fi MeshPoint Score

It was hard for me to test the coverage of the Dream Machine + BeaconHD combo mesh due to the issue with the plug. However, it’s safe to say the two can handle some 4000 ft² (372 m²) quite easily, or even more, as long as you can find an excellent place for the Beacon.

I tested the system for some 10 days and had no problems at all. There was no disconnection, and the connection was consistently fast enough to deliver 100 Mbps or faster Internet speed throughout my home.

Design and Setup
4 out of 10
8 out of 10


Reliable Wi-Fi coverage and performance

Super-easy to set up and manage via the UniFi mobile app

Beautiful status light


Bulky without a pass-through power socket

Can only fit in a single or two-outlet wall face-plate

No network ports, no dedicated backhaul band

Only works with UniFi controllers

Firmware update requires the web interface


The UniFi AP BeaconHD Wi-Fi MeshPoint is a niche mesh point – it only works with an existing UniFi controller, like the UniFi Dream Machine router. And then, it makes a remarkably convenient and well-performing add-on mesh unit.

Design-wise, though, you first need to have a suitable wall socket waiting for it, which can be a huge issue for most homes. Keep that in mind before getting yours.

  1. So – outside of the lousy design taking up a whole socket ( which had to have the faceplate removed entirely because they are the more modern square variety )- I’m finding clients that are simply 12-14 feet or less away in the same room still prefer to associate to other ap’s – ones that are actually farther away and in all cases are on the other side of one or more concrete walls! So my conclusion is that this isn’t extending any range at all unfortunately. Not sure if this is a faulty unit – but it’s pretty much going back as such.

    • Assuming you have set it up properly and your client supports hand-off, Craig, that might have had something to do with the hand-off trigger level. More in this post. Unifi hardware is generally very good with seamless hand-off in my experience but not plug-n-play.

  2. Have you or anyone found out if it supports RADIUS?
    It seems any clients that attempt to connect through one of these fails when using RADIUS

    • RADIUS is more of an enterprise solution and handled by the router, not a mesh point, Chris. And no, I haven’t tested it.

  3. Can this be used as an ap for the udmp or extender only ? do you have any recommendation for the udmp? I will be using this at home over gigabyte speed 15-40 devices probably. I got the usg a month ago but too slow with throughput and the 4 ap’s I have are Legacy only 2.4. I notice no 5 .The udmp will be here next week I want to start with Atlease one good ap 2.4/ 5ghz and upgrade later the road or maybe even mesh with some of the older ap. I know threat feature Are still buggy from What I read but this gotta be much better then the netgear rax120 which lacks armor bitdefender,no advance feature via app and the GUI sucks still old looking would be better if there had DumaOS But yeah I want more control of the network and beable to upgrade down the road. So a decent ap not to over price for newbie.

    • It likely will, Mike. But it’s not an AP, it has no network port, so it’ll be a wireless mesh point, like an extender. As a result, the speed might be too slow for your needs. Read the review for more.

  4. One thing that helps is if you do not put the rubber pads / feet on it. I found that once I took the pads off, the Beacon fit much better.
