The DLB 2-9B is a versatile, very efficient, and stable 2.4 GHz CPE. This product is equipped with an extreme output power (up to 31 dBm) 802.11n MIMO radio wrapped securely inside a robust, well designed and a small form factor enclosure. The robust hardware is coupled with a 9dBi directional panel antenna; ideal for short to medium range applications.
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. Tested to meet vibration, temperature, drop, salt, fog, and electrical surge standards to ensure a high level of reliability and backed by a two-year warranty. It is equipped with a grounding lug and a grounded 24-volt PoE to allow a professional installation, resistant to electrical surges.

New Hardware platform
Powerful new generation CPU ensures better performance delivering higher up to 170 Mbps capacity and almost 2 X higher packet per second rate (80000). Narrow (5 and 10 MHz) channel support ensures steady performance in noisy environments. More RAM improves the performance with multiple users connected to a single base-station and larger flash stores a 2nd failover firmware image.
Integrated surge protection
3 kV line to ground and 1 kV line-to-line protection allows operating in a harsh weather conditions and unstable electrical installations.
New OS
New operating system includes all the essential features for point-to-multipoint networks. User interface is built using HTML 5 technology with responsive design. Among the new features there are IPv6 bridge and router support, SSDP and Bonjour device discovery options, flexible traffic shaping and SSTP client. New generation DLB devices are backwards compatible with APC series from Deliberant even when using iPoll protocol. In order to achieve this a new firmware image has to be installed on all APC devices (v7.0 or later).
iPoll 2 – enhanced performance protocol
iPoll 2 uses a centralized control scheme, where the base station polls every subscriber station (CPE) and ensures smooth packet transmission for voice, video and data. The polling method is smart: stations having data are polled more often versus idle ones.
Usage recommendation:- PTP mode (two LigoDLB 2-9B devices): 5,5 km/ 3.42 mi
- PTMP mode (DLB LigoDLB 2-9B as a client device): 3,5 km/ 2.17 mi
- PTP full capacity mode (two LigoDLB 2-9B devices): 2,5 km/ 1.55 mi
Maximum throughput: 170 MbpsHotspot scenario support
Starting from v7.52 Infinity firmware image can be used on a LigoDLB series devices for the outdoor hotspot and other related applications. After the firmware upgrade DLB devices are converted into access points for outdoor hotspot networks and will lose the functionality of point-to-point or point-to-multipoint connectivity.
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 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
