Product brochure

LigoDLB Propeller 2 is a universal device and can be used in a 2 different ways. It has a unique mechanism to do mechanical antenna parameter shifting and achieve the best performance in different operating modes (AP or CPE). Download our brochure to find out the main benefits about the Propeller 2 model.

New Hardware platform

Powerful new generation CPU ensures better performance delivering higher up to 170 Mbps capacity and almost 2 X higher packet per second rate (80000). Narrow (5 and 10 MHz) channel support ensures steady performance in noisy environments. More RAM improves the performance with multiple users connected to a single base-station and larger flash stores a 2nd failover firmware image.

Integrated Surge Protection

3kV line-to-ground and 1kV line-to-line protection allows operation under harsh weather conditions and unstable electrical installations.

LigoWave OS

LigoWave OS contains all of the essential features for establishing fast, strong, and reliable PTMP networks. The LigoWave OS includes IPv6 Bridge & Router Support, SSDP & Bonjour Device Discovery Options, Flexible Traffic Shaping, DHCP Option 82, and more. The user interface is built on HTML5 with responsive design.

iPoll 3: Enhanced Performance Protocol

LigoWave’s iPoll™ PTMP (Point-to-Multi-Point) proprietary protocol is an innovative solution, eliminating transmission congestion and close-cluster interference created in wireless PTMP installations.

Hotspot scenario support

Starting from v7.52 Infinity firmware image can be used on a LigoDLB series devices for the outdoor hotspot and other related applications. After the firmware upgrade DLB devices are converted into access points for outdoor hotspot networks and will lose the functionality of point-to-point or point-to-multipoint connectivity.


LinkCalc is LigoWave’s free wireless outdoor link planner and bandwidth calculator. It allows users to design wireless PTP/PTMP networks using virtual maps without the need for on-site field surveying or specialized tools. The data provided with LinkCalc can also be used to quote potential customer projects.

The DLB Propeller 2 is a new generation wireless device designed for client and small scale base-station applications. It has a unique mechanism to do mechanical antenna parameter shifting and achieve the best performance in different operating modes (patent pending).

This product is equipped with a MIMO radio (up to 23 dBm) and 11 dBi dual-polarized antenna which make the device ideal for short to medium range wireless communication.

Our dual firmware image will allow safe software upgrades. The device will restart using the prior firmware in the event of an upgrade failure.

The DLB Propeller 2 uses an advanced and feature-rich operating system which supports bridge/router and repeater modes (repeater mode allows the product to operate as an access point and as a station at the same time). The DLB OS also supports LigoWave’s iPoll2 (proprietary wireless communication technology) to increase throughput, packet per second rate and stabilize latency on your network. It has a user-friendly HTML 5 based GUI with instant reconfiguration without a reboot, includes useful installation tools (site survey, delayed reboot, spectrum analyzer, ping, traceroute) and is compatible with our standalone and cloud based Wireless Network Management System (Infinity Controller) – one of the most advanced management tools on the market.

The DLB Propeller 2 can be rotated to the horizontal orientation for use as a client device. This greatly reduces interference, as the main noise source is on the azimuth. Alignment is easy as only left and right movement of the device is necessary (no need to move it upwards or downwards as the antenna angle on the elevation is wide).



Ligowave DLB OS



The DLB OS is a highly functional and easy to use operating system. This powerful and flexible operating system ensures flawless operation of all DLB hardware devices and effortless setup for those deploying the networks.

  • Smart polling data transmission protocol (iPoll 2)
  • Dual-firmware image support
  • Responsive HTML 5 based GUI
  • 170 Mbps capacity
  • 80,000 PPS rate
  • IPv6 support

Ligowave DLB Infinity Controller


The Infinity Controller is LigoWave’s proprietary element management system that facilitates network installation, configuration, control, maintenance, monitoring, and expansion.

The Infinity Controller is designed to work with Infinity (NFT), LigoDLB, and LigoPTP NEs. It offers full functionality with the Infinity series and LigoDLB series, but only supports the monitoring feature on LigoPTP NEs. The PTP configuration feature is currently undergoing development
