Model: 1756-EN4TR

The 1756-EN4TR communication module is the information entrance for all kinds of intelligent terminals to access the Internet of Things, and is the key link between the perception layer and the network layer of the Internet of Things. Here are some common types of communication modules:

Bluetooth module: Often used for communication between devices such as mobile phones and smart wristbands.

ZigBee module: a low-speed and short-distance transmission of wireless communication equipment, often used in the restaurant ordering system and other scenarios.

WiFi module: 1756-EN4TR widely used wireless communication module, the communication distance is usually within tens of meters.

4G or 5G module (NB-IoT) : Similar to mobile phone communication, you need to insert a calling card. NB-IoT (Narrow Band Internet of Things) is a cellular-based narrowband Internet of Things communication method, which has the characteristics of wide coverage, strong connection, low power consumption and low cost.

In addition, 1756-EN4TR has some other communication modules, such as LoRa module, mainly used in drones and other equipment, the communication distance is generally a few kilometers to tens of kilometers.

1756-EN4TR The choice of these communication modules depends on the specific application scenario and requirements, such as transmission distance, power consumption, cost and other factors. In the field of the Internet of Things, the wireless communication module is the key to realize the interconnection between devices, and is of great significance to promote the development of the Internet of Things.
