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.

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.

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

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

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

√  7Normal SIM card

√  APN dedicated network card

√  IOT network card

Support wide voltage

7S1 supports wide voltage , and it meet a variety of industrial
scenarios for wide voltage requirements

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 the 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 respond in time.
