Medium-low rate

LTE Cat 1 network,
downlink peak rate 10Mbps,
uplink peak rate 5Mbps

High reliability

Built-in hardware watchdog, wide-voltage
power supply based on 9-36V,
and remote FOTA upgrade

Multimode

Support European LTE
mainstream frequency bands

Low latency

4G LTE network carrier,
millisecond latency experience

Basic Function

USR-G771 quickly delivers the bi-directional transparent transmission
of data at serial ports and networks.

Network Mode

Support European mainstream
LTE frequency bands.

Provide wide coverage and high stability
based on existing 4G operator networks.

Provide network access through
a general 4G network adapter.

Support the GPRS network, and ensure
the availability of communication.

Transparent Transmission mode

The serial device is connected with the network server through G771 to
deliver bi-directional transparent transmission of data.
The product supports 4 socket links, and keeps these 4 links
independent of each other.

Registration Package plus
Heartbeat Package

A registration package is sent to a server to identify the device,
and a heartbeat packet is sent to a server to judge the active state of the device.
A heartbeat packet is sent to a serial terminal to actively collect data.

Parameter Configuration

Support the parameter configuration of serial,
network and SMT AT commands, and provide the configuration tool for the PC.

Remote FOTA Upgrade

With the remote management platform,
it can realize the automatic firmware upgrade
Have a small upgrade package of differential algorithm,
and this can save upgrade traffic and time.

Product Details

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.
