COFDM IP Mesh radios are the latest innovations in the expanding
range of Cobham Surveillance solutions with domo technology at
their core.
Up to 8 of the radios can be combined into a ground-breaking IP
mesh network - Cobham’s first fluid, self-forming, self-healing mesh.
Offering genuine non-line of sight coverage (COFDM), the system is
truly mobile and therefore supplies a network with extended range
- one which will deliver in environments too tough for other radio
solutions to cope with.
Wireless networks no longer need to be static. Unlike other wireless
options, the COFDM IP Mesh constantly readjusts itself as nodes
move, working out which are in range and finding the best route to
send data between them. When one node can no longer operate, the
rest of the nodes can still communicate with each other - directly or
through one or more intermediate nodes.
The highly flexible mesh topology means that data can be exchanged
between moving nodes in a point to point or point to multipoint
fashion, and range can be extended by using nodes as repeaters.
With a COFDM IP Mesh system, any shape of mesh network can be
built:
A chain network: Ideal for range extension, each node is placed
at the outer range limit of the node before. These then chain
together to feed information back. This network can be operated and
maintained whilst mobile.
• A star network: Good for urban coverage, a central node is
situated at a high point to act as a relay and all other nodes
feed information back via that one, enabling bi-directional
communications.
• A random network: Evolves organically to any shape.
• A combined network: Any of the above shapes can be linked
- if they are operating at different frequencies, they can be
combined at the IP layer.
COFDM IP Mesh from Cobham offers true networked integration of
video, audio and GPS, with seamless transfer of MPEG4 video even
when the mesh is reconfiguring to a different shape.
The robust, self-healing mesh architecture makes the product ideal
for use in mobile surveillance applications, command and control, or
advanced robotics.
