Function/Feature Strix Systems Mesh Dynamics Comments Mesh Protocol YES - True Strix engineered Dynamic Mesh NO - Based on distance-vector IP routing. Meshdynamics is a 20-man company and started shipping its first products in 2005. Architecture - Layer 2, and NOT based on Not a mesh networking product 850 nodes have been shipped to date (not an indication of sold or installed). The Spanning Tree MD4000 product is software running on non commercial, non carrier-grade off the shelf hardware. The current selection is the Avila board manufactured by Gateworks. WiFi cards/radios are OEM'd from Ubiquiti (SR2, SR5, SR9, SR4). The unit runs Linux in kernal mode and is managed soley through a proprietary "Network Viewer". The MD4250 (2-radio), 4350 (3-radio) and 4450 (4-radio) products offer bridging and non optimized mesh protocol. MeshDynamics has few small deployments, created their own ISP in one town and no customer-paid municipal- wide deployments. Testing performed at Airforce lab and small implementation for study.

Strix Systems is recognized as the Technology and Market leader in Wireless Mesh Networking (see http://www.lightreading.com/document.asp?doc_id=104787&WT.svl=wire1_5). Strix Access/One® integrated DMA (Strix Dynamic Mesh Architecture™) is comprised of Strix High Performance Modular Architecture™ (HPMA™) and Strix Scalable Mesh Fast Re-route™ (SMFR™). Industry-proven performance, reslience, scalability and reliability designed-in. A single integrated product that meets all FCC and carrier-class requirements for the smallest indoor deployments to country- wide high-speed transportation systems. Testing by IoMetrix independent testing lab which found that Strix Access/One has the Industry’s Largest Capacity, Highest Performance, and Zero Degradation Through Multiple Hops (See Addtl Central Management Gateway NO YES Meshdynamics products require the Structured Mesh Gateway (SMG) at central Required locations whereby nodes forward the IMCP packets to the SMG PC using a proprietary protocol. The received SMGP packets are translated back to IMCP packets for the Network Viewer software. The Network Viewer commands/changes on the PC are sent back to the corresponding SMG using SMGP. The received SMGP packets are translated and sent as IMCP packets to the mesh units. Strix Access/One products do not require a gateway to manage a single or multiple nodes, small to large scale mesh network architectures or the translation or flow of traffic from one destination to another. Ease of Deployment YES Initially Although Meshdynamics suggests that the products can handle large-scale deployment, the product is unmanageable for anything but a few nodes. Features such as real-time details per end node and user, rogue detection and multi-node managed network configuration and software updates do not exist. Strix hardware and software is designed and manufactured by Strix Systems. Strix products take minutes to deploy - not hours. Strix offers "Any Service, Any Radio" in "Any Configuration" with complete flexibility to install the network as needed while not requiring excessive external devices. All configuration enhancement/changes are easily accomplished remotely through web browser and does not require proprietary Pre-staging required NO YES Meshdynamics is untested in anything but small-scale deployments. The company does not offer high-grade professional services. Field sales support can be hired for assistance. Strix Access/One does not require pre-engineering. Strix Access/One includes Access Point and Backhaul capabilities in a single architecture. Self-Configuring YES YES Meshdynamics is a WDS architecture. Units are preconfigured with IP addresses that must be changed. Wireless is available 3 to 5 minutes after power applied.
