200km IP MESH UHF VHF Center Multi-unit Transmission System
Introduction
IP MESH adopts Safe Guard's keep technology of COFDM modulation as its core, allows a group of mesh nodes form a seamless and highly safe private network in NLOS and moving conditions.
The COFDM IP MESH network can be in chain network, star network, or random networks.
The chain network is ideal for range extension to reach a maximum range.
The star network is great for application in urban environment mission coverage.
The random network allows mesh nodes to organize themselves in any shap
Unlike other wireless solutions, the IP MESH has self-managing ability.
The COFDM IP MESH keeps adjusting itself when node working in moving condition, to select the best route for range extension and signal communication between each mesh node.
What’s more, the IP MESH is also self-healing, when one of the node stops working, the rest of the nodes can communicate with each other directly or through one or more intermediate nodes.
