Ubiquiti UniFi AC In-Wall Access Point

UniFi AC In-Wall is a compact indoor access point designed to be mounted on the wall instead of a standard Ethernet socket. This solution is ideal for upgrading an existing network infrastructure. The device is able to provide high performance to both legacy wireless clients and the latest AC / AC-Wave devices.

UniFi AC In-Wall supports PoE connectivity, and also allows PoE equipment to be connected via RJ-45 connector. Up to two devices can be connected to the access point via 10/100/1000 Ethernet cable. Modern WiFi 802.11a / b / g / n / ac standards in 2x2 MIMO configuration provide enough power for stable signal reception in medium-sized rooms

Overview Ubiquiti UniFi AP AC In-Wall

The dimensions of the Ubiquiti UniFI AP AC In-Wall are very small and are only 139.7 x 86.7 x 25.75 mm. Despite such a small amount of space in the casing, the manufacturer managed to install a dual-band radio transmitter, with a total power of 20 dBm (both when operating on 2.4GHz and 5GHz). Unfortunately, it was not possible to install stronger antennas in such a small box. Nevertheless, the device's capabilities are sufficient to cover the area of an average room. Aside from WiFI distribution, the access point can also function as a classic Ethernet socket. The device has been equipped with three ports, one of them is used for receiving PoE power and connecting to the network. The other two ports are used for connecting client equipment.

UniFI AP AC In Wall Configuration

UniFI AP AC In Wall is controlled by the UniFi OS Console software suite and can be integrated on the same network with other devices from the UniFi series. The access point is part of the UniFI SDN (Software-Defined Networking) platform, which enables monitoring and control of end devices on the network, all within the intuitive UniFI Controller graphical interface. The platform provides network monitoring, device management, maps and statistics display.

UniFI Advantages:
  • Multiple SSIDs with different types of security features.
  • Unlimited system expandability with additional UniFi devices.
  • No license fees
  • Speed limitation according to SSID
  • Advanced AirTime Fairness and Band Steering features.
  • RF environment scanning.

Spectrum analyser

The transmitting frequency of the device is exactly matched to the bandwidth, no free space between channels. As can be seen in the diagram from the analyzer, the device generates slight noise up to -82dBm. This is not a large value, for a typical home device the behavior is sufficiently correct.

Signal map

We used the AirSurvey software to run the signal map. To read the signal levels correctly, please note the color legend at the bottom of the image.

The location of the AccesPoints has been marked with an appropriate icon.

The shape of the antenna beam causes that the device transmits poorly up and down. However, it should be regarded as a positive effect consistent with the concept of mounting the access point against a wall as an outlet. In the case of buildings with many floors, the devices would interfere with each other, and so everything is fine. UniFI AP AC IN Wall in this version should be regarded as a transmitter for one particular room, possibly a neighboring one, nothing more.

Speed test

We measured the speed using WiFIPerf software and the speed test server was iperf3 software.

Summary

UniFi AC In-Wall significantly extends the possibilities for concealed installation of access points within a single UniFi network. This solution also allows to provide high-speed Internet access for rooms where installation of open access points is not possible. In ordinary rooms, this type of installation is also rational, as it does not require additional space beyond the Ethernet cable route. A pleasant addition is the prepared cover of the device for quick replacement of the housing in a different color. This will certainly help to fit the device into the room.

We noticed two design issues:

  • The size of the unit makes it impossible to mount in places where we have many boxes, such as 2-3 boxes next to each other (per frame). The equipment simply does not fit and looks bad.
  • In the case of a double Ethernet socket, we don't have much to do with one of the wires. Fortunately, this is compensated for by the two outlets on the bottom.
