The Easiest Way to UniFi

DATASHEET

Model: UDM

Build your home or oce network with the UniFi® Dream Machine,
model UDM. Powered by a fast 1.7 GHz quad‑core processor, the
UDM combines multiple functions into a single elegant device:

• High‑Performance 802.11ac 4x4 Wave 2 Access Point (AP)

• Managed 4‑Port Gigabit Switch

• Advanced Security Gateway

• UniFi Network Controller

The UDM is the ideal rst UniFi device. It’s easy to use and still oers
all the benets of UniFi for homes and businesses. Easily expand
the UDM by adding more UniFi Switches or APs while managing
the network with the integrated controller.

The UniFi Network app and UniFi cloud provide remote access
to the controller from anywhere. The entire network can be kept
updated and safe with automated software updates, which are free
of charge.

Powerful Security

The UDM oers advanced rewall policies and persistent threat
management to act as an Intrusion Prevention System (IPS) and
Intrusion Detection System(IDS).

Automatic QoS

Top QoS priority is assigned to voice and video trac for clear calls
and lag‑free video streaming.

Convenient VLAN Support

The UDM can create virtual network segments for security and
network trac management.

VPN Server for Secure Communications

A site‑to‑site VPN secures and encrypts private data
communications traveling over the internet.

Scalable UniFi Network Controller

DATASHEET

Management Capabilities

The UniFi Network Controller can provision UniFi devices, map
out networks, and quickly manage system trac. Important
network details are logically organized for a simplied, yet
powerful,interface.

Network Overview

From a single pane of glass, view network topology and
conguration, real‑time statistics, and debugging metrics. Monitor
your network’s vitals and make on‑the‑y adjustments as needed.

Deep Packet Inspection

Ubiquiti’s proprietary Deep Packet Inspection (DPI) engine includes
the latest application identication signatures to track which
applications (and IP addresses) are using the most bandwidth.

Detailed Analytics

The UniFi Network Controller provides congurable reporting
and analytics to manage large user populations and expedite
troubleshooting. Advanced search and sorting capabilities make
network management more ecient.

Multi-Site Management

A single controller running in the cloud can manage multiple
sites: multiple, distributed deployments and multi‑tenancy for
managed service providers. Each site is logically separated and
has its own conguration, maps, statistics, guest portal, and
administratoraccounts.

RF Environment

Detect and troubleshoot nearby interference, analyze radio
frequencies, and choose optimal AP placement. The auto‑optimize
feature congures the UDM with best practice settings, and the
included radio AI capability optimizes channel selection using a
genetic algorithm.

Advanced RF Performance

RF performance and conguration features include spectral
analysis, airtime fairness, band steering, and cell‑size tuning.

LAN/WLAN Groups

Create multiple LAN and WLAN groups and assign them to the
respective UniFi devices and VLANtags.

Predictive Maps

Upload a map or use Google Maps to represent the areas where
your UniFi devices are located. Use the predictive map feature* to
get a preview of coverage, and to help you avoid deadspots.

Wireless Uplink

Wireless Uplink functionality enables wireless connectivity
between APs for extended range, wireless adoption of APs in their
default state, and real‑time changes to network topology.

Guest Portal/Hotspot

Congure custom settings, including authentication, Hotspot
setup, and the option to use your own external portal server.

DATASHEET

802.11ac Wave 2 has become the de facto Wi‑Fi radio standard, no
matter what the environment.

Home use requires extremely high throughput (4x4MIMO streams)
for video streaming; low‑latency gaming; and local video, photo,
and le transfers: the UDM delivers the requisite high‑performance
Wi‑Fi and includes integrated Ethernet ports for attaching
localmedia.

The UDM is also ideal for enterprise use: it ts into high‑density
environments as part of the overall enterprise network – small,
remote corporate oces, retail stores, and hospitality locales.
You can also expand Wi‑Fi coverage by adding more APs via the
built‑inswitch.

DATASHEET

802.11ac Technology

Initial 802.11ac Wave 1 SU‑MIMO (Single‑User, Multiple Input,
Multiple Output) technology allows an earlier‑generation AP, such as
the UniFi AC Pro AP, to communicate with only one client at atime.

802.11ac Wave 2 MU‑MIMO (Multi‑User, Multiple Input, Multiple
Output) technology allows a Wave 2 AP, such as the UDM, to
communicate with multiple clients at the same time – signicantly
increasing multi‑user throughput and overall user experience. The
following describes a 4‑client scenario:

MU-MIMO Assuming the same conditions, a Wave 2 AP
provides up to 75% improvement1 overall over a Wave1 AP. This
improvement increases wireless performance and/or serves more
clients at the same performance level.

4x4 Spatial Streams At any single time, a Wave 2 AP can
communicate with the following MU‑MIMO clients:

• four 1x1 clients

• two 2x2 clients

• one 2x2 client and two 1x1 clients

• one 3x3 client and one 1x1 client

A 4x4 Wave 2 AP delivers up to 33% greater performance1 than a
Wave 1 AP that is 3x3 in both radio bands.

Real-World Performance Combining the performance increases
from MU‑MIMO technology and the use of 4x4 spatial streams, the
UDM delivers up to 125% greater performance1 than a typical Wave
1 AP.

Client Compatibility For optimal performance, use MU‑MIMO
clients. SU‑MIMO clients will also benet and gain up to 10‑20%
greater performance when used with the UDM.

 Actual performance values may vary depending on environmental and installation conditions.

High-Density Scenarios

Both Wave 1 and Wave 2 APs oer 28 independent
(non‑overlapping) channels: three for the 2.4 GHz band and
twenty‑ve for the 5 GHz band, including DFS channels.

When you use the 2.4 GHz band in a high‑density location, you
encounter self‑interference and channel saturation.

When you use the 5 GHz band, you can deploy smaller cells
(coverage areas), so you can support more clients in any cell that
deploys more than one AP.

With the advantages of MU‑MIMO technology and 4x4 spatial
streams, the UDM can support more than triple the number of
users2 than a typical Wave1 AP.

In practice, the maximum number of users the UDM can support is
limited by radio link airtime. This depends on the amount of trac
each device creates, types of devices, network conguration, and
the presence of other APs on the same channel.

Recommended Maximum Number ofUsers

70 Users

125 Users

As a theoretical maximum, the UDM supports the maximum
number of users as specied by the 802.11ac standard.
