Strix Unveils WiMAX Strategy for Mesh Networks

Strix Systems, a start-up based in Calabasas, California, outlined its strategy for implementing WiMAX and mobile WiMAX in high-performance, large-scale mesh networks. Strix's existing Wi-Fi-based mesh technology already provides many WiMAX-like capabilities, including broadband coverage with a range of several hundred meters outdoors. WiMAX promises to increase range and quality of throughput with an Orthogonal Frequency-Division Multiplexing (OFDM)-based modulation technique that will achieve a maximum coverage radius outdoors using OFD Multiple Access (OFDMA).


Strix currently supplies a high-capacity multi-radio, multi-channel, and multi-RF mesh networking solution. Strix's Access/One Network OWS supports up to six radios per node, enabling some dedicated radios to be used for backhaul ingress, backhaul egress, and client connectivity. The design can use any combination of 802.11a, b, or g radios. The multi-radio mesh architecture segments the network and supports QoS for voice and other applications.


Strix plans to offer in-network upgrades that add WiMAX radios to existing mesh nodes. This will deliver 802.16 backhaul capabilities for the Wi-Fi mesh. In late 2006 or early 2007, Strix will also add the capability to support mobile access via WiMAX.

Which
Mesh Architecture is Best for Delivering VoIP?

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.
