Cellular Gateway is a device with switching capabilities.Information can be transferred and repackaged between different communication protocols and data to meet the needs of the system.Cellular Gateway also has filtering and security features.Popularly speaking, we all know that we need to go through a door from one room to another.Then the transmission of information from one network to another will inevitably pass through a gateway, which is Cellular Gateway.In the era of intelligent technology development, the Internet of Things products on the market are rich and colorful, which brings great convenience to people's lives.In order to realize network connection and facilitate R & D and production, manufacturers have integrated Cellular Gateway and WIFI.This forms the Cellular Gateway of the Internet of Things.

Cellular Gateway can be divided into protocol Cellular Gateway, application Cellular Gateway and security Cellular Gateway.Protocol Cellular Gateway is mainly used for protocol conversion between different protocols Cellular Gateway;Applications Cellular Gateway is a Cellular Gateway designed specifically for some applications;Security Cellular Gateway is to ensure the security of data, filter data information, and set up firewalls.

The application modules of Cellular Gateway can be divided into two parts:

1. Two hosts need to communicate with each other. Cellular Gateway can be used to connect two different networks.

2. Considering the cost, energy consumption and quantity, some intelligent devices and industrial devices use protocol devices that cannot be connected to the Internet.However, in order to achieve the purpose of remote control, Cellular Gateway is needed to convert the protocol into a network.We can call it the Ethernet Cellular Gateway.

There are many types of Cellular Gateway, such as relay Cellular Gateway, transmission Cellular Gateway and protocol Cellular Gateway.One of the most frequently used is the relay Cellular Gateway,It has the characteristics of high performance, high security, high reliability, high maintainability and rich functions.It is often used between telecom operators and large enterprises, and its advantages are obvious.

IoT Cellular Gateway is commonly used in the following industries:

1. Logistics industry: In logistics container transportation, containers are often in an environment with a large difference in temperature and humidity.Therefore, it is necessary for Cellular Gateway of the Internet of Things to design energy consumption and deal with security performance, so as to prepare for different environmental conditions.

2. Healthcare industry: The healthcare industry often requires data imaging in the radiology department through Internet of Things devices.In order to avoid radiation exposure and other problems, Cellular Gateway of the Internet of Things can handle imaging devices in a safe way.Provide security for the healthcare industry.

3. Rescue vehicle industry: rescue vehicles such as fire engines and ambulances need Internet of Things equipment such as cameras, navigation and radar to improve their work.Mobile Cellular Gateway can connect Internet of Things devices to external networks for safe and reliable access.
