Tropos networks are based on a fully distributed mesh architecture. With no centralized controller, the Tropos mesh architecture eliminates single-points-of-failure, performance bottlenecks and unnecessary network traffic. The architecture’s distributed intelligence dynamically selects the optimal end-to-end paths through the network by evaluating multiple RF links, channels and bands. It also performs functions such as advanced RF resource management, VLAN enablement, and security and QoS policy enforcement. The Tropos mesh architecture is self-organizing, simplifying deployment of new networks and enabling ease in expanding existing ones.
Designed to deliver superior capacity, resiliency, security and scalability, Tropos’ mesh architecture utilizes decentralized distributed intelligence that enables each Tropos mesh router to make intelligent coordinated routing and airtime management decisions in real time, maximizing bandwidth and system performance.
The Tropos mesh architecture is based on open-standard IP networking and radios. A common physical infrastructure can be leveraged to support multiple applications. The Tropos mesh architecture is built on field-proven mesh technology that includes Tropos’ outdoor optimized routers; the patented Tropos Mesh OS built from the ground-up for large scale, mission critical networks; and Tropos Control, a carrier-class wireless network management system. It economically and seamlessly extends networks and systems from offices and equipment yards into the field, improving operational efficiency and enabling new services.
Features and benefits of the Tropos mesh architecture include:
Tropos networks can deliver more than 10 Mbps throughput at each mesh router and less than 1 ms latency per mesh hop, supporting multiple current and future applications.
Tropos networks implement a number of advanced RF resource management algorithms that improve the performance and reliability of communications in both licensed and unlicensed spectrum.
Tropos mesh networks easily and economically scale from small hot zones with few users and limited data traffic up to large coverage areas with large numbers and hundreds of routers connecting thousands of end users/end-point devices transferring massive volumes of data.
Tropos mesh architecture is controller-free providing high resiliency with multiple redundant communications pathways, and dynamic selection of RF channels and RF bands to ensure high availability. Tropos networks can be designed to provide very high availability.
Tropos networks integrate standards-based multi-layer, multi-application, defense-in-depth network security. Each Tropos mesh network router incorporates an integrated firewall and IPsec VPN plus authentication and encryption capabilities. The Tropos mesh architecture is FIPS 140-2 certified and meets NERC-CIP 002-009 requirements for critical cyber asset protection.
Tropos networks deliver seamless, session-persistent roaming for users at highway speeds and enable clients to traverse nodes, gateways and IP subnets within the mesh with their application sessions, including VPN sessions, persistently and transparently preserved.
Tropos networks are centrally configured and managed with a comprehensive and scalable out-of-band network management system.
The radios used in Troops routers are designed and built in-house so that they are tailored to the unique needs of large, outdoor networks. They provide superior receive sensitivity and are equipped with precision ceramic filters that eliminate near-band signals from other radio systems. Tropos radios are tuned for maximum rate at long distances, not just short-range performance.
Tropos mesh routers are ruggedized, weatherized and electrically hardened. Their packaging can survive continual and extreme vibration and shock. They can withstand extreme heat, cold, wind, rain, snow, ice and humidity, including hurricanes. Their electrical hardening includes telecom-grade surge and lightning protection, and they comply with IEEE 1613 environmental requirements for networking equipment in electric power substations.
In summary, Tropos networks are uniquely capable of delivering the coverage, capacity, performance, reliability, security and scalability required in a wireless IP communications infrastructure. Tropos mesh routers have been installed in the field since 2002. They are used by more than 1,000 customers in more than 50 countries around the world.
