1. What is transparent transmission technology? 

Transparent transmission means that in the process of data transmission, this set of data does not change in any form through wireless means, as if the transmission process is transparent, while ensuring the quality of transmission, intact to the final receiver.

The concept of the Internet of things is gradually replacing the Internet as the focus of attention. Relevant organizations predict that by 2020, the number of devices installed in the Internet of things will reach 28.1 billion, and a highly personalized and interactive Internet of things world is emerging.

2. Why transparent transmission? 

Transparent transmission is generally used to read remote serial port data. For example: the person that every go up inside net cafe wants to brush id card ability to get online, but id card database is put impossibly inside every net cafe. Therefore, the serial port data of the card reader is transmitted to the public security bureau through transmission, and the id number is compared on the platform of the public security bureau.

3. Advantage application of transmission module 

At the technical level of object to object connection,Bluetooth,Wi-Fi, ZigBee and other wireless transmission technologies almost cover the path chosen by the industry. After long-term development, transmission technology has been relatively mature, and data integration and sharing has been expanded in the application of cloud platform. Here, in order to meet different market demands and realize data transmission and collection, in addition to cloud communication and multi-cloud communication, it also extends the transmission technology of Internet of things to connect data resources more directly.

To realize intelligent device transparent transmission data will need to rely on wireless transparent transmission module, these modules can realize the length of the sender and receiver data and content completely consistent, do not need to do anything with the data, the equivalent of a cable or a serial port line, can be widely used in industry, environmental protection, meteorology, geology, agriculture, and many other industries.

Transparent transmission module, can rapid convergence intelligent transformation and upgrading of products, suitable for intelligent wearable devices, intelligent instrument, logistics tracking, health care, intelligent household, automotive electronics, recreational toys, security monitoring, intelligent irrigation, and other areas of the industry, integrate the existing scheme in the shortest development cycle, and help customers quickly occupy the market, winning advantage.

In addition, sim based router wtih this kind of module has the following advantages: 

1. Save traffic: the module has built-in network communication protocol, support MQTT Internet of things special protocol, greatly save data traffic, improve the control efficiency and success rate; 

2. Data security: after multiple data encryption, there is no data leakage problem; 

3. Easy to use: wireless change the user's existing protocol, without protocol definition and analysis, transparent data transmission.

At present, the intelligent upgrading and transformation services provided by the transmission module have covered ten fields such as industry, agriculture, fire protection, logistics, home furnishing, security, environmental protection, medical treatment, transportation and power grid, which has played an important role in facilitating the realization of intelligent life.

As transparent transmission 4G sim router, the E-Lins H685 series 4Gsim based routerwith Ethernet is a compact, ruggedized 3G/4G/LTE cellular networking solution designed for mission-critical connectivity in the most challenging environments. It is qualified for M2M (Machine to Machine), IoT (Internet of Things) and In-Vehicle applications. Super mini size suitable for embedding applications.

In addition to the robustness, reliability, security, friendly-using, the H685 4G sim based routerwith Ethernet is competent to be engineered to protect against extreme temperatures, humidity, shocks, vibrations, dust, reverse polarity, and transient voltage, which is widely used in more than twenty industrial fields, such as CCTV security surveillance, AMR, vehicle, retails, vending machines, power control, water schedule, traffic, oil field, weather forecast, environmental protection, street lamp control, post, bank and many other fields.
