How is centerless ad-hoc networking established, and can it still communicate without a public network?

A centerless ad-hoc network means that terminals do not rely on a server, a base station, or a public network; instead, they discover neighbors by themselves and form a mesh network. The IDM MCC580 portable multi-mode converged communication terminal, once powered on, automatically searches for terminals on the same frequency and establishes mesh links, so that any two terminals can reach each other, with voice, video and data shared within the network; when a link is interrupted, services are automatically rerouted through other nodes, and the network provides self-organizing and self-healing capabilities. The site requires no pre-deployed infrastructure: group audio and video communication can be enabled as soon as the terminals are in place, which suits environments without public network coverage such as basements, mountainous areas and tunnels; when the primary link fails, the IDM MCC580 automatically switches over to the backup link within 50 ms.
