Small Form Factor


LigoWave presents a new smaller form for the base station’s enclosure, which is lighter yet still retaining IP66-rated weather protection. Smaller packaging reduces freight costs and makes them less obvious. The new design has no metal parts, which makes them lighter and corrosion resistant.

Innovative Mounting Bracket


The adjustable mounting bracket is very easy to assemble and install. It consists of two easy-to-connect parts that allow tilting the device up and down when installing on a pole.

Pole Mounting

Tilt the device in any of four directions—up, down, left, or right—with the DLB Pole Mount, thus ensuring ideal precision tilting and optimum link adaptability.

Hardware Built to Last


A powerful new generation CPU ensures better performance delivering higher—up to 170Mbps—throughput and almost 2× greater packet per second rate (80,000). The addition of RAM improves performance, allowing multiple users to be connected to a single base-station, and the larger flash capacity 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. The LigoDLBac Series are backward-compatible with LigoDLB devices through the iPoll 3 Proprietary Protocol.

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 with v7.52, Infinity firmware can be used on LigoDLB devices for outdoor hotspot and related applications. The firmware upgrade converts the DLB base station from a PTP/PTMP device into an access point for outdoor hotspot networks.

DLB 5-90n

LigoWave’s DLB 5-90n delivers the highest performance and stability available in the 5GHz Base Station class. This product combines a highly advanced radio core containing MIMO 2×2 technology with an integrated, high-gain, dual polarization directional antenna. The feature-rich operating system is optimized for ultra-high performance wireless communications. The smart dynamic polling based protocol (iPoll 3) ensures reliable communication even in congested areas with 64 client devices connected to a base-station. 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 polycarbonate plastic with UV inhibitors to provide years of outdoor exposure in direct sunlight without cracking. The DLB 5-90n was designed and tested to meet an IP-66 rating as well as vibration, temperature, drop, salt, fog, and electrical surge standards to ensure a high level of reliability unsurpassed in the in the industry.


New form factor

The shape of the enclosure is now smaller, lighter and retains the IP-66 weather protection rating. Smaller packaging reduces freight costs and makes them less obvious. The new LigoDLB 5-90n design has no metal parts, which makes them lighter and corrosion resistant.


New mounting

The adjustable mounting bracket is very easy to assemble and install. It consists of two easy to connect parts that allow tilting the device up and down when installing on a pole. A metal strap is included to securely tighten the device. This design includes additional reinforcements and thicker materials to ensure survival in extreme climate conditions.



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.
