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

3 kV line to ground and 1 kV line-to-line protection allows operating in a 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.


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 ECHO 5 was designed for cost-effective and long distance connectivity (up to 50 km). It has a unique mounting system designed to utilize standard satellite offset dish antennas to provide increased system gain and distance. These antennas are readily obtainable in most countries, thereby reducing freight and inventory costs. The aluminum housing improves RF performance, allowing solid communications in interference laden environments as well as providing strength against the elements.

DLB ECHO 5 is a universal device that can be used in a two different ways: with a 60 cm offset dish antenna provided by LigoWave or with a 3rd party offset dish antenna.

The product is equipped with a high output power MIMO radio (up to 29 dBm) and when coupled to LigoWave’s 27 dBi dual-polarized, 60 cm, offset satellite dish antenna it is ideal for ultra long range wireless communication.

Equipped with LigoWave’s dual firmware image feature, remote software upgrades are assured even if a power failure interrupts the process. The device will restart using the prior firmware in the event of an upgrade failure.

The enclosure is made of aluminum and polycarbonate plastic with UV inhibitors to provide years of outdoor exposure in direct sunlight without cracking and survive in harsh weather conditions. Environmentally tested to meet an IP-67 rating as well as vibration, temperature, drop, salt, fog, and electrical surge standards to ensure a high level of reliability and backed by a two-year warranty. It is equipped with a grounding lug and a grounded 24-volt PoE to allow a professional installation, resistant to electrical surges.

Ligowave DLB Infinity Controller


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 3)
  • Dual-firmware image support
  • Responsive HTML 5 based GUI
  • 170 Mbps capacity
  • 80,000 PPS rate
  • IPv6 support
  • Infinity Controller compatible


Ligowave DLB OS


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.
