Interference and Collocation Interference Demonstration

Radio interference occurs when two or more RF systems affect one another’s smooth operation. This normally occurs when two or more RF systems are operating physically close to one another and they are operating in such a way that one of the transmitters negatively impacts one or more receivers. Through this demonstration video you will learn how to analyze and mitigate collocation interference on a ship and also how to analyze and find solutions for interferences between ground radio stations.

To develop the next generation of smart products, organizations are turning simulation to improve device performance and drive profitability.


To what extent has the Taiwan Unmanned Vehicle System been on track from MIRDC's perspective

In this presentation, MIRDC’s Bionic Intelligent Automatic Guided Vehicle (BI-AGV) is introduced. This “collaborative handling module” has three characteristics of wireless intelligence, flexible use and flexible movement. Through the wireless intelligent collaborative handling system, it can control several automatic guided vehicles (AGVS) in real time, and several vehicles can conduct remote control and serial connection to carry out handling tasks. At the same time, the 360-degree mobile omni-directional wheel design framework is adopted. It has the advantages of flexible use in the area where the traditional unmanned vehicle cannot run smoothly in the indoor narrow space.
