Tropos is the proven leader in delivering truly ubiquitous, metro-scale, Wi-Fi mesh network systems. Deployed in over 150 customer sites worldwide, Tropos MetroMesh routers quickly and economically use the intelligent Tropos Predictive Wireless Routing Protocol (PWRP™) to provide pervasive coverage over metro areas. PWRP forms a wireless mesh, dynamically routing traffic along the highest throughput path to a wired gateway. This intelligent routing negates effects of radio frequency (RF) interference, wired backhaul failure and mesh router failure. PWRP scales to thousands of nodes with the lowest routing overhead in the industry. Network support costs are minimized via the central management capabilities of the Tropos Control element manager, a configuration, monitoring and maintenance tool.
