Firetide Multi-Service Network
The Firetide mesh system provides a high capacity, self-healing wireless mesh network that operates seamlessly indoors and out-doors. Designed for maximum performance, scalability, mobility and security, the mesh delivers throughput of over 150 Mbps per radio link. Firetide’s patented AutoMesh™ routing protocol makes the mesh fully self-forming and self-healing, to afford rapid deployment and dependable operation for both static and mobile mesh infrastructures. Mesh-wide performance is constantly optimized with unique AutoMesh features such as flow based routing, congestion control, cost-based bandwidth metrics and industry-leading low latency. Multiple auto-sensing 10/100/1000 Mbps Ethernet ports on each HotPort node create a virtual Ethernet switch, providing direct connectivity to devices such as video surveillance cameras and Wi-Fi access points, forming a high-performance multi-service infrastructure. The mesh nodes can operate in bonded or linear radio mode and support 900 MHz, 2.4 GHz, 4.9 GHz and 5 GHz bands.
In the bonded mode, both radios are combined to operate as a single interface that provides double the bandwidth of a single radio equivalent. This is ideal for bandwidth intensive applications such as video surveillance, resulting in crystal clear video images. This mode also provides a “fat pipe” for point to point wireless backhaul—for example, to connect two mesh networks. In the linear mode, both radios operate independently enabling sustained bandwidth levels over an unlimited number of hops. This enables long linear topologies, such as when networking a railway line, and provides a sustained level of service to every node, which is also critical for large municipal networks.
Optimal Network Performance
The HotView software incorporates a number of unique flow control, traffic prioritization and management capabilities to deliver high throughput and low latency needed to support concurrent voice, video and data communications.
- Bandwidth metrics improve overall throughput by selecting best transmission paths based on link capacity, link type, hop count, and link retransmission count.
- During high network utilization, HotView manages and mitigates traffic congestion on a per flow basis. Three levels of congestion control are triggered by traffic in transmit queues and overall link capacity.
- Mesh traffic can be prioritized by Ethernet port or by 802.1p QoS based high, medium, or low field values in order to optimize video or voice applications.
- With flow-based routing traffic is balanced across the mesh to best optimize aggregate throughput and increase network performance. Flows are established between source and destination nodes and are balanced based on link-specific traffic loads and class-of-service priorities.
- Network performance can be optimized incrowded environments by manually removing redundant links from the mesh.
- To reduce network traffic and improve overall performance, broadcasts can be contained to a single mesh or multiple contiguous meshes.
- Static Route Assignments can be implemented to ensure the highest possible performance between any two source and destination nodes.
- In poor RF environments transmit data rates can be locked-in at a lower rate to reduce re-transmissions and ensure constant throughput.
- Multi-Hop optimization reduces contention in mesh topologies with numerous redundant paths.
- Received Signal Strength (RSSI) Threshold settings prioritize paths by link quality.
- For improved performance over longer distance routes, the Extended Range feature enables timing parameters to be optimized for longer propagation times.
- Adjustable transmit power levels minimize interference within the mesh, while Dynamic Frequency Selection (DFS) minimizes radio/radar interference.
- Virtual LANs segment and direct traffic along specific VLAN routes.
