Description

DLB 5-20n

LigoWave’s DLB 5-20n delivers the highest performance and stability available in the 5 GHz CPE 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 while optionally allowing compatibility with older 802.11 a standard devices.

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 5-20n 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 industry. It is equipped with a grounding lug and a grounded 24-volt PoE to allow a professional installation, resistant to electrical surges.

 

New form factor

The shape of the enclosure is now smaller, lighter but retains the IP-65 weather protection rating. Smaller packaging reduces freight costs and makes them less obvious. The new 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.

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

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.
