ALB-250 Series - 5 GHz band
Carrier-class 802.16 broadband wireless solution

PRODUCT OVERVIEW
Albentia Systems introduces the ALB-250 series, the new family of high performance OFDM broadband wireless backhauling and bridging solution compliant with the IEEE 802.16-2009 standard (WiMAX) designed for use in the 5GHz unlicensed bands with aggregated capacity up to 104 Mbps.ALB-250 belongs to the ALB-200 family of IP-oriented point-to-point solution based on the IEEE 802.16-2009 OFDM standard. ALB-250 series can also be used in Point-Multipoint networks thanks to the compatibility with the ALB-400 Point-Multipoint backhauling system An ALB-250 point-to-point long distance link is able to provide an unprecedented net throughput thanks to the combination of an advancedframe-based contention-free Medium Access Control layer and a robust and high performance hardware platform. Unprecedented Spectral-Efficiency The use of a frame-based contention-free MAC layer maximizes the net spectral efficiency by avoiding packet collisions and unused idle time. This highly efficient use of the spectrum allows more robust modulation schemes with lower Signal-to-Noise ratiorequirements, providing outstanding net throughput in log distance links. The physical layer is able to provide a maximum over-the-air rate of 104 Mbps ( SAE series ) . Thanks to the high efficiency of the ALB250 MAC, this gross capacity can be translated into 70 Mbps of aggregated Ethernet available throughput. Advanced layer-2 scheduler and QoS mechanisms ALB-250 equipment incorporates an advancedlayer-2 scheduler which allows prioritization and physical layer resource allocation for multiple differentiated service flows. Capacity for critical services like professional video transmission can be guaranteed in combination with general purpose Ethernet data. APPLICATIONS - Carrier-class point to point radio links - Professional backhaul solution - Point-point and Point-Multipoint solution -Radio links for LAN bridging - Professional video transmission systems

SYSTEM DESCRIPTION
A completepoint-to-point link comprises a pair of ALB-250 units, acting as master and slave units. Each station includes a weatherproof outdoor unit with optional 23dBi integrated directional antenna, and an indoor unit for interfacing with the system. The indoor and outdoor units are connected through standard cat5 Ethernet cable. System integration and service provisioning is supported by a powerful andintuitive management system based on SNMP, web, command line interface and an innovative XML-RPC based remote configuration system. The solution incorporates powerful mechanisms to guarantee a secure and reliable communication, including authentication, Automatic Repeat Request (ARQ), 3DES encryption and robust adaptive modulation and error-correcting mechanisms.
