SAFE GUARD was founded in 1999, which is a leading global technology manufacturer specializing in wireless microwave video and data communication system for government, law enforcement, military, defense, UAV/UGV and broadcast markets, etc..

We have strong production and R&D groups. Our backbone in researching and production is from the previous state-run 806 plants and 54 Institute. Over the past years, SAFE GUARD has been devoting itself to designing and developing digital video audio wireless systems in mobile. Nowadays, SAFE GUARD has built up a mature COFDM product line, mainly including standard COFDM wireless transmitter & receiver, TDD-COFDM full duplex Ethernet transceiver, COFDM IP MESH, and the latest technology FDD-COFDM wireless Dual frequencies Network Transceiver. Moreover, we offer customized solutions and services for clients to any kinds of wireless transmissions they need--simplex, duplex, or mesh network.

Our COFDM systems have been exported to more than 32 countries covering Asia, Africa, Europe...especially in Middle-East. Each product goes through strict test and inspection with US original (HP) spectrum analyzer and Germany (Rohde & Schwarz) Network Analyzer. We aim to design and provide exclusive advanced wireless transmission system worldwide. Your support and feedback are our motivation!

WIRELESS MESH NETWORK EMERGENCY COMMUNICATION SYSTEM

Wireless MESH is able to communicate with other networks and is a dynamic network architecture that can be continuously expanded. Any two of MESH nodes can maintain wireless interconnection.

Wireless MESH network is based on the mutual cooperation and coordination among each MESH node. It has the advantages of high speed broadband, high spectrum efficiency, and outstanding characteristics such as dynamic self-organization, self-healing, and self-maintenance.

Wireless MESH Network is a multi-hop network, which is developed from ad hoc network. It’s one of the key technologies to solve the "last mile" problem. MESH Network is an indispensable technology in the evolution to next-generation networks.
