COFDM IP MeshPolice commandThe IP Mesh network constantly assesses which nodes arein range and the best route to send data between them.Central commandCameraCamera behind houseSOLO TransmitterTactical monitoring Camera car Mobile surveillanceTechnical featuresCOFDM IP Mesh radios exchange data on a single frequency,simplifying frequency management. The entire mesh occupiesjust 2.5MHz (3 and 3.5MHz also available) of bandwidth. Farnarrower than WiFi or WiMax bandwidth, this gives less noisein the channel, better sensitivity and increased spectrum formore users. Utilising proprietary domo narrowband videocompression technology, very high quality video can betransmitted over the mesh network.Custom-designed for the security and military markets, the IPMesh radios employ the unique Cobham COFDM modulationscheme and therefore have excellent RF penetration andperformance in the presence of multipath. An IP data rate of upto 3.5Mb/s is possible (data rate depends on mode, number ofnodes, and range between nodes), and this can be symmetricto match network requirements. Diversity gives protectionagainst fading, and there are built-in guard intervals and errorcorrection.Security of the entire mesh network can be ensured by the useof the optional AES128 or AES256 encryption. Control of thewhole deployed mesh is achieved using a comprehensive webbrowser application with a built-in user-loaded mapping facilityand PTZ controls.The COFDM IP Mesh solution is supplied in a ruggedweatherproof chassis and is available in a long range 1Wversion. It can also be upgraded with composite video andaudio, input and output options.KEY: Mesh 1 Mesh 2 SOLO link outIP mesh systems enablethe backhaul ofmultiple audio feedsfor monitoring bysurveillance teams.A Mesh network takes data from itsnodes and broadcasts, non-line ofsight, to a nearby police commandpoint.Networked integrationof video, audio andGPS, with seamlesstransfer of MPEG4video even during networkreconfiguration.Robust, self-healingmesharchitecture makesthe COFDM IP Meshideal for use in mobiletracking applications.Data can be filtered and sentonward to central command centresfrom a local monitoring point.30For further information please contact +44 (0)1489 566 750
