Network standard:

2G/3G/4G/5G modem: Use different generations of mobile communication networks for data transmission.

NB-IoT modem: a modem specifically designed for Narrowband Internet of Things communication.

LoRaWAN modem: a modem based on Long Range Wide Area Network technology.

Wi-Fi modem: a modem that uses Wireless Fidelity for data transmission.

Features:

Data upload 4G LTE modem: responsible for uploading the data collected locally to the cloud platform or central server.

Remote control 4G LTE modem: it can realize the monitoring and control of remote equipment and realize remote operation.

Multifunctional 4G LTE modem: with multiple functions, such as data acquisition, remote control, alarm notification, etc.

Location 4G LTE modem: built-in location module, which can realize location tracking and location information reporting of the device.

It should be noted that the classification of 4G LTE modems may vary depending on different manufacturers or specific application scenarios. When selecting and using a 4G LTE modem, it should be selected according to actual needs and technical requirements to ensure its adaptability and reliability.

Selection guide for 4G LTE modem

Choosing the right 4G LTE modem is critical to building reliable remote monitoring and IoT applications. Here are some selection guidelines to help you determine the right 4G LTE modem for your needs:

Communication method:

Select the wired or wireless communication mode according to the actual field environment and network conditions. If you already have a reliable wired network, a wired 4G LTE modem may be a better fit; A wireless 4G LTE modem may be more convenient if long distance communication or temporary installation is required.

If wireless communication is selected, the corresponding 4G LTE modem is selected according to the mobile network type (2G/3G/4G/5G) and coverage in the area where the device is located.

Network standard:

LoRaWAN modems may be a cost-effective option if long distances are required and the number of devices is small. However, make sure that there is reliable LoRaWAN network coverage in the area where the device is located.

If the device needs to switch between mobile networks of different operators, it is more flexible to choose a 4G LTE modem that supports multiple mobile communication standards.

Functional requirements:

Determine whether specific functions such as data collection, remote control, alarm notification, etc. Are required. Different 4G LTE modems may offer different combinations of features, so choose the right model for your specific needs.

If you need to track the location of your device, choose a 4G LTE modem with the location.

Reliability and safety:

Ensure that the industrial 4G LTE modem with good reliability and stability is selected to adapt to the harsh industrial environment. Be careful to choose a 4G LTE modem with appropriate security features, such as data transmission encryption, authentication, firewall, etc., to protect the security of data.

Compatibility:

Communication protocol: Make sure the 4G LTE modem supports the communication protocol you are using, such as TCP/IP, Modbus, OPC, etc. Review the device specifications and specifications to confirm communication compatibility with your system or device.

Data format: find out if the 4G LTE modem can handle your data format. If you use a specific data format (such as ASCII, JSON), make sure that the 4G LTE modem can parse and transmit the data correctly.

Interfaces and ports: check the interface type and number of ports of the 4G LTE modem. Make sure they are compatible with your system or device and that they meet the requirements for connectivity and interaction.

Easy to integrate:

Programming interface: find out if the 4G LTE modem provides an easy-to-use programming interface or development kit to easily integrate into your application or system.

Configuration and management: choose a 4G LTE modem with a friendly configuration interface and management functions. In this way, you can easily perform operations such as parameter setting, network configuration, and remote management, and reduce the complexity of integration and maintenance.

Component compatibility: if you are already using other hardware devices or software systems, ensure that there are no conflicting integrations between the 4G LTE modem and these components. Consider electrical compatibility between devices, data transmission requirements, etc.

Here are some common guidelines for 4G LTE modem maintenance:

Cleaning: Regularly clean the 4G LTE modem device, including the case, connection interface, and heat dissipation components. You can use a soft cloth or brush to wipe gently, and avoid using detergents containing corrosive or solvent substances.

Environmental adaptability: ensure that the 4G LTE modem equipment is installed in a suitable environment to avoid the influence of excessively high or low temperature, humidity, dust, and other harmful substances.

Stable power supply: ensure the power supply of 4G LTE modem equipment is stable, avoid sudden power failure or voltage fluctuation, and pay attention to the endurance of the battery (if any) and replace or maintain it in time.

Update firmware: pay attention to the latest firmware version released by 4G LTE modem device manufacturers, and upgrade the firmware when appropriate to improve the stability and functionality of the device.

Regular running test: run the 4G LTE modem device regularly to ensure its normal operation and stable connection. It can be tested by means of simulated data transmission or remote access.

Troubleshooting: if the 4G LTE modem device is found to be faulty or the connection is abnormal, troubleshoot and repair it in time. Refer to the device manual or contact the vendor's technical support department for assistance.

It should be noted that 4G LTE modems of different models and brands may have different maintenance requirements. Please follow the specific instructions and instructions provided by the equipment manufacturer during use. In addition, depending on the actual situation and application requirements, other specific maintenance measures may be required to ensure the normal operation and long-term reliability of the 4G LTE modem.
