Features:

LigoWave’s DLB 2-90 delivers the highest performance and stability available in the 2.4 GHz Base Station class. This product
combines a robust, highly advanced 802.11n radio core containing MIMO 2x2 technology with an integrated, high gain, dual
polarized, 100° sector antenna. The device is powered by a reliable, advanced, and feature-rich operating system, allowing the
creation of high throughput, stable wireless networks quickly and effectively. Although the DLB 2-90 was designed mainly as a
Base Station it also supports client-operating mode, which greatly extends the possible application scenarios.
The smart dynamic polling based protocol (iPoll 2) 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 2-90 was designed and tested to meet an IP-65 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. The mounting
bracket permits installation on a wall or a pole and provides up to 30 degrees of down-tilt adjustment.

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.

WNMS
WNMS is a FREE enterprise grade Wireless Network
Management System. A single software solution simplifies
a large number of management and monitoring tasks for
network administrators. LigoWave’s comprehensive network
management system supports several thousands of nodes.
Multiple networks may be maintained and monitored using
one server. A rich feature set helps to diagnose network
problems effectively, visualize networks on a map, perform
scheduled firmware upgrades automatically, track states of
devices, get failure alerts, and collect statistics. The Webbased
system environment supports multi-user accounts.
Several administrators may manage different networks on the
same server, without having access to each other’s equipment.
WNMS is available as a stand-alone version for Linux and
Windows servers, as a cloud-based system and as a mobile
application for Android devices.
