Introduction
IWAVE digital wireless link assisted an excavator manufacturer to complete the research and development of their unmanned excavator. with a digital data link, workers could operate the excavator from a safe distance using line-of-sight and a remote control to perform tasks such as digging, dumping, and grading. This allows operators to be away from unstable terrain, falling debris, and other hazards.

Background
Why make excavators unmanned? In fact, due to reasons such as working environment and ability requirements, the excavator industry generally has a manpower shortage problem that makes it difficult to recruit workers. Excavator operators will also encounter problems such as landslides and bad weather, which pose huge challenges to industrial production. Based on this, the market has a growing demand for unmanned excavator vehicle system. Therefore, how to make the excavation process as unmanned and intelligent as possible to reduce the accident casualty rate has become a direction that major excavator manufactures are actively seeking to transform.
IWAVE digital video sender work as a wireless link for transmitting various data from excavator to remote control center. It enabled the autonomous machine operator get the real time HD video and data in the remote control station. With the HD video and data, the operator could pay attention to the on-site conditions around the excavator to ensure a safe operation.
Challenge
●The locations where excavators operate are often remote and the 4G signal quality is poor, so the excavator's remote control systems cannot rely on any public network.
●Most construction machinery is in a mobile state, and blasting operations often occur, so there are very high requirements for the stability and reliability of mobile video transmission.
●The geological environment is complex, which require the video transmitter and receiver has strong nlos ability and mobility.
●These large machinery sometimes has to work underground. So the main challenge was to provide reliable and seamless COFDM digital video transceiver in underground areas of operation.
●There are various sources of data that need to be transmitted wirelessly, which required the rush video transmitter ultra high bandwidth and ultra-low latency.
Solution
IWAVE Ultra-reliable Nlos Wireless Video Transmitters with short delay is special design for autonomous excavator.
Utilizing the network characteristics of large bandwidth and low latency, real-time high-definition video and other sensor data are transmitted back to the control center in real time for operators to perform remote operations based on on-site conditions.
The mobile video transmitter module installed in the robot excavators can send data from each platform of the excavator and multiple video streams to the host in real time. After calculation and processing, the host can obtain the working status of the excavator and then send it to the monitoring center. The monitoring center analyzes and processes the excavator's working parameters, and the operator can remotely control the autonomous machine directly through the robust Mobile Ad-hoc Networks. IWAVE long range transceiver mimo modules FDM-6600 and FDM-6680 provide stable and reliable data communication services between the construction site and the control center.
