LigoDLB 2-90n


LigoWave’s DLB 2-90n delivers the highest performance and stability available in the 2.4GHz Base Station class. This product
combines a robust, highly advanced 802.11n radio core containing MIMO 2×2 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 2-90n 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 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 2-90n 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.
