LigoWave ligoDLB 2 Outdoor Wireless Device Outdoor PTP

LigoWave’s DLB 2 is a versatile, very effi cient, and stable 2.4 GHz access point. This product is equipped with an extreme output power (up to 31 dBm) 802.11n MIMO radio wrapped securely inside a robust enclosure. The two N-type connectors allow the connection of external antennas suited for a wide range of applications. The powerful radio core is coupled with an advanced and feature-rich operating system, optimized for high performance wireless communications while optionally allowing compatibility with older 802.11 b/g standards devices. The smart dynamic polling based protocol (iPoll 2) ensures reliable communication even in congested areas with 64 client devices connected to the base-station. Equipped with LigoWave’s dual fi rmware image feature, remote software upgrades are assured even if a power failure interrupts the process. The device will restart using the prior fi rmware in the event of an upgrade failure.

DLB 2

    LigoWave DLB 2 is a versatile, very effi cient, and stable 2.4 GHz access point. This product is equipped with an extreme output power (up to 31 dBm) 802.11n MIMO radio wrapped securely inside a robust enclosure. The two N-type connectors allow the connection of external antennas suited for a wide range of applications. The powerful radio core is coupled with an advanced and feature-rich operating system, optimized for high performance wireless communications while optionally allowing compatibility with older 802.11 b/g standards devices.
    The smart dynamic polling based protocol (iPoll 2) ensures reliable communication even in congested areas with 64 client devices connected to the base-station.
    Equipped with LigoWave’s dual fi rmware image feature, remote software upgrades are assured even if a power failure interrupts the process. The device will restart using the prior fi rmware 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 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.

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 2)
 • Dual-fi rmware image support

 • IPv6 support
 • WNMS compatible

WNMS

  WNMS is a FREE enterprise grade Wireless Network Management System. A single software solution simplifi es 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 fi rmware upgrades automatically, track states of devices, get failure alerts, and collect statistics. The Web-based 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.
