Why CAT 1 Dominate Medium-Low Rate IOT Markets?
With the inevitable retirement of 2G and 3G, expensive 4G CAT 4 networks
and slow NBIOT networks, embedded LTE Cat 1 Modem WH-LTE-7S1-E,
provides new solutions for Medium-Low Rate IOT communication, and offers best
choice to users in terms of rate, latency, power consumption, cost and so on.
Basic Function
Quickly deliver the bi-directional transparent transmission of
data at serial ports and networks.
data at serial ports and networks.
Block Structure
Transparent Transmission mode
The serial device is connected with the network server through 7S1 to deliver
bi-directional transparent transmission of data. The product supports 4 socket
connections, and keeps these 4 connections independent of each other.

Registration Package plus
Heartbeat Package
Heartbeat Package
A registration package is sent to a server to identify the device, and a heartbeat package is sent to a server to judge the active state of the device, and a heartbeat package is sent to a serial terminal as the command to actively collect data (the contents of registration and heartbeat packages and the heartbeat interval can be modified by a command).
Configuration of User Parameters
Support the parameter configuration of serial, and network and SMS AT
commands, and provide the configuration tool for the PC
commands, and provide the configuration tool for the PC
Remote Upgrade
7S1 supports remote FOTA upgrade, cooperates with the remote management platform to imperceptibly and automatically upgrade the firmware. Small upgrade package of differential algorithm enables the product to save upgrade traffic.
SIM card interface

Support wide voltage
7S1 supports wide voltage , and it meet a variety of industrial
scenarios for wide voltage requirements
Case of the Transmission of Sharing
Payment Terminal via Internet
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 the bi-directional transparent transmission of data at serial ports and networks,
with ease of use, and release you from subsequent operations once configured.
