The LKAV-3510 multicast mesh node is able to deliver video, voice, and data signals over IP networks in a complex environment with a wide coverage, strong diffraction ability, high transmission rate and self-defined security encryption. The mesh is suitable not only for PTP communication, but also centerless multi-hop ad-hoc network. Each mesh node can access up to 32 nodes. According to the working environment and the number of nodes, LKAV-3510 throughput up to 70Mbps, transmit distance can be extended through multi-hop. As mesh self-organizing/self-healing features make it very suitable for motion surveillance with high quality image and emergency communication. It can be applied to Public Security, Armed Police, Fire Control, Civil Air Defense, Military, EOD Robot and UGV to establish real-time and rapid communication and unified coordination and command.
