Application Case
Quickly responding, G771 uploads the alarm data via Internet as soon as possible, thus ensuring the safety of lives and property.
Case of Agricultural IOT Environmental Monitoring
G771 can quickly upload the data collected by sensors in agricultural greenhouses to remote servers through the LTE or GPRS network to facilitate the control center to monitor the greenhouse dynamics in real time and respond in time.
Transmission of Charging Pile Data Through Internet
As a charging pile operates effectively, its running data can be quickly uploaded to a cloud server through the connected G771 to help the back-end operating personnel uniformly manage the data.
