Application Case
Case of the Transmission of Sharing Payment Terminal via Internet
In this scenario, 7S1 can quickly upload terminal data and issue server commands, bringing good interaction experiences to consumers. The sharing payment solution using 7S1 provides the following advantages:
- Support LTE, enjoy stable networks, millisecond delay of data communication, and provide good payment experiences
- Support GPRS, and automatically switch over GPRS in the case of unstable LTE while meeting requirements and ensuring communication quality
- Support bi-directional transparent transmission of data at serial ports and networks, with ease of use, and release you from subsequent operations once configured.
Case of Agricultural IOT Environmental Monitoring

G7S1 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 provide timely responses.
