Strix Systems introduced a new, third-generation Outdoor Wireless System and a new High Performance Modular Architecture for large-scale mesh networks.
The new OWS 2400-30 offers increased user density, provides enhanced transmit power and receive sensitivity, a 30% smaller form factor and lower cost per radio compared to earlier products. The new design doubles from 64 to 128 the number of WLAN associations permitted per radio, allowing up to 768 concurrent users per node. Modularity lets the OWS 2400-30 scale to up to six radios as needed (802.11a/b/g/j, 802.16d/e, 2.4 GHz, 4.9GHz and 5 GHz in any access and backhaul configuration.
The new High Performance Modular Architecture offers Scalable Mesh Fast Re-route (SMFR) capabilities for distributed localized node intelligence, network topology-independent fast re-route, instant roaming, zero throughput loss, and zero latency over multiple hops. Strix said it is able to deliver cero throughput loss and zero latency for over 10 hops, enabling real-time applications and lowering OPEX costs for the number of wired connections needed for a given area.
When networks are turned up, every node automatically scans to locate all other network nodes and selects the best path to the wired node based on round-trip delay (RTD), signal-to-noise ratio (SNR), and other criteria. The nodes continue to scan and evaluate the best path and alternate paths to the wired node, automatically self-healing to the next-best path within milliseconds if the criteria of the best path drops below the set threshold or the path is blocked.
Strix also noted that in mobile applications, its Scalable Mesh Fast Re-route can deliver hand-offs for trains traveling at up to 200 mph.
SMFR also supports real-time node-state status indication, real-time backhaul path analysis, a congestion-avoidance algorithm, and an optimal channel re-use algorithm.

 | Which Mesh Architecture is Best for Delivering VoIP?  byCyrus Irani |
| For wireless data networks, voice is a "killer app." This article will first look at the four key mesh network performance requirements for real time applications; the three mesh architectural options when deploying wireless voice over IP (wVoIP) over a WiFi mesh network; how a multi-radio, multi-RF architecture positively impacts the capital cost to deploy; and the operating expenses involved to properly operate such networks. | |
