Ⅰ.IP MESH Introduction

MIMO IP MESH adopts Safe Guard's (SFGT) key 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 shape.

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 also has self-healing features, 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. With high flexibility in mesh topology, the data and video can be exchanged in poin-to-point, poin-to-multipoint or multipoint-to-multipoint.

II. IP MESH Command Center

SG-MESH-4 is the wireless IP MESH command center station, which is designed for outdoor application like in urban coverage, drones video surveillance, solider tactical mission deploy, etc.. The SG-MESH-4 COFDM IP MESH is integrated with tablet computer for wireless mesh network system operation and video monitoring, and it can see the whole wireless MESH network topology. Also, PPT(Push-to-Talk) for voice communication is available, that is convenient to chat with other people who carrying the IP MESH node. There are also built with a battery V lock for standard Sony Lithium battery mounting or other same type Lithium battery. Besides the external battery, there are also have an power charger input for battery charging after running out of the power. WIFI and GPS function are workable, which is easy for user to identify each front end matchable IP MESH node's location.
SG-MESH-4 is ruggedizedly designed in Pelican Suitcase, which is shockproof, waterproof, and dustproof. It's in IP67 protection degree when shut off.
