Technology Behind Wireless Infrastructure Mobility

Firetide mesh networks are dynamic by nature, allowing for automatic and instantaneous connection and reconnection of mesh nodes to the network. A Firetide mesh node instantly associates with the mesh network, as it travels within range of another static or mobile mesh node.

The Mobility Controller takes it a step further and enables instantaneous handoff at high speeds or while traversing multiple mesh networks.

With the Mobility Controller, Ethernet devices such as IP video cameras, Wi-Fi access points, or RFID readers, can maintain network connectivity while traveling at high speeds across multiple Firetide mesh networks and IP domains. This enables a variety of real-time applications not possible with static Ethernet networks. These applications include:

  • Continuous video surveillance for mobile vehicles such as police cruisers, fire trucks, buses and trains
  • Uninterrupted, high-capacity Wi-Fi access on public transit
  • Portable and mobile network services on public transportation, first responder vehicles, fork lifts and cranes
  • Mobile command centers for emergency personnel

The Mobility Controller will be an integral part of a Firetide mesh deployment if your project requires mobile real-time voice, video or data at high speeds, or across multiple meshes.

The Mobility Controller manages connectivity between mobile and fixed nodes, ensuring fast and efficient handoff. One of the radios on the mobile node is used for data connectivity and the other radio continuously scans the environment, while the mobility controller maintains the data path.

Once the second radio picks up a stronger signal from an alternate mesh node, the data link is switched to that radio, while the first radio assumes the monitoring role. The fast switchover to the second radio ensures zero packet loss on the data link and maintains real-time nature of the connection.
