Overview

Designed for long-range applications, the LTU LR is a 5 GHz
subscriber station that functions as a CPE (Customer Premises
Equipment) in a Point-to-MultiPoint (PtMP) environment with the
LTU Rocket® as the basestation.

Proprietary LTU Technology

DATASHEET

Based on Ubiquiti’s LTU technology, the LTU LR is not impeded by
the limitations of standard 802.11 Wi-Fi technology. Its custom LTU
silicon and radio architecture provide up to 600+ Mbps1 of real
TCP/IP throughput and modulation rates of up to 4096QAM2.

CPE Modes

The LTU LR supports both bridged and built-in hardware NAT
router modes to suit your specic deployment.

Frequency Split

The LTU LR can use dierent frequencies for TX and RX to avoid
interference.

Improved Noise Immunity

The LTU LR directs RF energy in a tighter beamwidth. With the focus
in one direction, the LTU LR blocks or spatially lters out noise to
improve noise immunity. This is especially important in an area
crowded with other RF signals of the same or similar frequency.

 1+ Gbps with future rmware upgrade.

Innovative Design

Ubiquiti’s InnerFeed technology integrates the radio into the
feedhorn of a 26 dBi antenna, so there is no need for a cable. This
improves performance because it eliminates cable losses.

Quick Mounting and Alignment

The LTU LR features a large reector size and easy elevation
adjustment (azimuth is adjusted by rotation around the pole).

In a PtMP link, the LTU LR functions as CPEs to the LTU Rocket, which is paired with an airMAX® sector antenna.

Channel Width Flexibility

Channel width exibility allows independent TX and RX channel
frequency congurations anywhere within the radio band to avoid
local interference. Channel width options include the following:

• 10 MHz

• 20 MHz

• 30 MHz

• 40 MHz

• 50 MHz

• Up to 100 MHz*

Auto Power Adjustments

By default, the Auto Output Power option allows the LTU LR to set
the output power (EIRP) to the appropriate level.

Signal Control

The LTU LR's TX output power is controlled by the AP's target
TX output power. A PtMP network can manage signal levels
to enhance network stability and achieve optimal wireless
performance with the highest possible modulation.

DATASHEET

Convenient Conguration

To manage the LTU LR, you have two options: the LTU
Conguration Interface and Ubiquiti Network Management System
(UNMS™). Either option lets you manually congure the LTU LR.

Within the LTU Conguration Interface, you can manually congure
the LTU LR or manage it from the AP side using the Find My AP
feature. The LTU LR will automatically scan for APs using the same
channel bandwidth. Select the appropriate AP and then use it to
congure the LTU LR.

* Available with future rmware upgrade.

PtMP Dashboard

The Dashboard oers map and Fresnel views* so you can visualize
the network. The map view shows your PtMP links overlaid on a
geographic map, while the Fresnel view shows the link calculated
for your selected CPE, including line of sight, rst Fresnel zone, and
60% clearance zone.

New graphs provide instant status updates and help you to detect
connectivity issues and their eects on PtMP performance:

• The airtime distribution bar graph displays in real time how

much airtime each CPE is using. Click any point to view the
airtime and link score for a specic CPE.

• The AP RF environment bar graph shows ambient RF noise levels

across the frequency spectrum.

• The combined remote RF environment bar graph also shows

ambient RF noise levels but for the combined environment of all
of the remote CPEs.

• The local and remote RX rate histograms show the receive

modulation rates of the various CPEs.

Real-Time Spectral Analysis

airView® spectral analysis runs on a dedicated and independent
receiver, which has excellent EVM (Error Vector Magnitude)
performance.

The receiver can also perform other tasks, such as a search for
channel occupancy, DFS detection, and automatic channel/
frequency assignment. Calibration (signal level measurement
accuracy) and resolution bandwidth options are enhanced.
Spectral zoom (user-dened scan limits) is also available.

* Available for models equipped with GPS.
