airHaul2 Nexus PRO

The product listed on this page will only be manufactured on demand for special projects.

Please contact us for more details.

Product Overview

The airHaul² Nexus PRO is an intelligent dual radio wireless backhaul designed for Near Line of Sight (NrLOS), Point-to-Point (PtP) connectivity. It enables wireless operators and service providers to quickly deploy robust wireless backhaul links never before possible in NrLOS installations in the license free frequency bands.

Operating in the license free 2.4 GHz and 5.1 to 5.8 GHz ISM and UNI-II bands, the airHaul² Nexus PRO is a scalable and reliable communication-grade solution that delivers an unmatched combination of range, capacity and security, even in the most challenging environments.

In the Link Aggregation mode, the airHaul² Nexus PRO provides up to 45 Mbps of useful data throughput. In the Repeater mode, links can span up to 50 miles (80 km).

The low latency and low jitter of an industrial-grade airHaul² Nexus PRO provides reliable delivery of delay sensitive services including Voice over IP (VoIP), high definition video and prioritized data traffic, all “converged” over a single robust wireless link. The advanced Quality of Service (QoS) capabilities of airHaul² Nexus PRO enable operators to optimize the performance and usage of the wireless link, and offer differentiated Service Level Agreements (SLAs) for each service.

Application Scenario

Feature Highlights

Best-in-class dual radio performance with COFDM technology ensures high throughput, spectral efficiency, resistance to multi-path delays and NrLOS performance
Multi-band radio with 27 non-overlapping channels^* combined with smartBridges’ multi-band antennas provide powerful RF interference mitigation and immunity in the license free bands
High transmit radio power and ultra high receive sensitivity for LongRange™ coverage
Superior operational flexibility with repeater and link aggregator modes
Adaptive wireless modulation with automatic data rate selection that maximizes link performance according to environmental conditions
Traffic prioritization and QoS with low latency allows for Voice, Video and Data to be carried on a “converged” backhaul transport
Advanced Layer 3 networking functions of the edge router to deploy robust and scalable wide area wireless networks
Secure data communication using 802.11i with 128 bit AES (U.S. Govt. FIPS 197 compliant)
Unified Web and SNMP MIB-II compliant remote management interface
Dual Band antenna support for enhanced RF interference mitigation and path loss reduction
Purpose built for harsh outdoor environments, encased in heavy-duty aluminum housing, this fully weatherized outdoor unit operates from -49ºF to +140ºF (-45°C to +60°C)

Superior Operational Flexibility

Based on the award winning and field proven Nexus platform, this dual radio architecture provides operating mode flexibility and addresses the risk mitigation challenges facing carriers. This unprecedented performance comes from the Best-in-Class radios working with the high performance network processor employing cutting edge software technologies.

For maximum uptime, the airHaul² Nexus PRO provides fully redundant system configuration. In addition, the Watch Guard feature continuously monitors the device and performs an automatic recovery, thereby realizing high system availability.

Enhanced Security

The airHaul² Nexus PRO employs state-of-the-art data encryption algorithms complying with the IEEE 802.11i standard to secure wireless data. In addition, wireless data can be encrypted with strong 128 bit AES that complies with FIPS 197 for US Federal Government applications.

Quick and Easy Deployment

Field installation is expensive and time-consuming; therefore, the airHaul² Nexus PRO kit is designed for rapid out-of-the-box installation. With the easy to use backhaul, simple to use software and audio tone antenna alignment aid, the network can be setup rapidly and cost-effectively.
