Tropos Networks is the proven market leader in delivering metro-scale Wi-Fi mesh network products and services. Their solutions delivers true wireless broadband (>1 Mbps) over large geographic areas using low-cost standard Wi-Fi clients. The innovative MetroMesh architecture provides maximizes throughput from client to server, eliminates the need for costly and complex per node wiring and automatically self-organizes as nodes are added or subtracted, backhaul supplied or removed, and interference comes and goes.

MetroMesh maximizes return on investment by allowing one physical network to be separated into multiple secure virtual segments for use by different municipal departments and by the public. These networks are enabling mission-critical broadband applications in mobile public safety environments, such as mobile database access, video surveillance, and GIS inquiries. They are delivering residential consumer access as well as serving small businesses and nomadic users.

Tropos™ MetroMesh™ OS provides the industry's most sophisticated mesh routing intelligence. Designed from the ground up to optimize throughput in a dynamic metro-scale Wi-Fi mesh environment, the MetroMesh OS, creates a self-organizing and self-healing wireless mesh, and intelligently select the optimum data path to the Internet.

Tropos MetroMesh OS is the key to delivering high throughput and scalability. It is the industry's only mesh routing software that dynamically selects end-to-end paths through the mesh based on maximizing client-server throughput and minimizing latency. The result is MetroMesh user performance that is >2x greater than potential alternatives. MetroMesh OS is also the industry's only mesh routing software that maintains low protocol overhead regardless of the number of nodes in the network, using less than 5% of the aggregate bandwidth.

Tropos MetroMesh is composed of four elements:

• Predictive Wireless Routing Protocol (PWRP™) - is the industry's only mesh routing algorithm that selects routes based on maximizing client-server throughput
• Virtual network infrastructure - allows many different user communities using a metro-scale Wi-Fi mesh network to each have their own private network, offering its own address space, classes of service and security settings, running over a single metro-scale Wi-Fi mesh infrastructure. For example, in a municipal Wi-Fi network, various departments such as police, fire, emergency services, building inspections and public works could each have its own network that could be administered separately from the others with different access and security policies.
• Metro-cale mobility - enables session-persistent client mobility across a metro-scale Wi-Fi mesh network, including mobility across different IP subnets, with total transparency to clients. Metro-scale mobility maintains VPN session persistence as users move throughput the coverage area and supports mobile voice and video applications.
• Multi-layer security - combines time-tested and proven Internet security techniques with the inherent intelligence of MetroMesh routers to create a robust, multi-layered security framework that uses both the security features of MetroMesh routers plus best-of-breed third-party solutions.
