Introduction

4G Module USR-LTE-7S4 is used to transmit data between serial port and network server by Operator network. It is configured by AT Command and work in dual transparent transmission mode. USR-LTE-7S4 is in small size, which is widely used in LTE, WCDMA, TD-SCDMA. It works in transparent transmission mode and more functional software. It has high speed and less time-delay , supports FTP protocol. We add Watch dog function to ensure the stability if work for a long time.

Working Mode Introduction

1. Network transparent transmission mode

In this mode, User’s device can send data to specifie server by LTE network. G780 support 4 socket links. Four links are mutual independence.

2. HTTPD Client Mode

In this mode, User’ device can send/obtain data to/from HTTP server directly. The data will sent to Web server (apache, IIS, tomcat etc) in Http (GET/POST) mode as long as sending data in formal format. User can utilize the scripting language like PHP, ASP as database storage.

3. SMS transparent transmission mode
