Product Name:LTE CAT 1 modems |cellular mdems

  • Model:USR-G771-E

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 works, 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.
