COFDM Wireless IP Mesh Network For Mining Geological Exploration
Product Description:
HMISVM01 vehicle-mounted ad hoc network radio transmission frequency range can be customized from 300M to 1.5G , using our new generation of multi-hop ad hoc network protocol radio technology, capable the ability of combating complex channel environments realizing the completion of non-center co-frequency ad hoc networks broadband transmission among individual soldiers, vehicles, drones and other mobile points and fixed points under complex scenarios.
The device has a built-in large-capacity lithium battery, which is designed compact, with a maximum 2W transmit power, allowing users to quickly establish a private network in emergency scenarios to provide users with stable transmission channels for IP data services such as voice, messaging, and video.
Key Feature:
*The same frequency network reduced occupancy of frequency resources
*Wireless IP network can distribute IP address automatically
*Multi-channel image can be transmitted under the same frequency
*One single point can have access to multiple single points
*Centerless network and no single point failure have increased the system reliability
*Arbitrary relay transmission is available and this can increase the transmit distance
*Each site can be connected arbitrarily
