Which 4G module manufacturer is the best?

At present, there are still many 4G module manufacturers , and customers can choose suitable modules according to their own needs. The 4g module ZHS491G developed and produced by Chengdu Zongheng Intelligent Control has relatively complete functions, 7-mode 16-band full network communication, provides RS485/TTL/DO/DI/AI and other interfaces, and supports GPS positioning. It uses Qualcomm chips and works stably and reliably. , it is a 4G module with great advantages in terms of price and performance.

What is a 4G module?

The 4G module refers to a collection of basic circuits whose hardware is loaded into a designated frequency band and whose software supports the standard LTE protocol. The hardware integrates radio frequency and baseband on a small PCB board to complete wireless reception, transmission, and baseband signal processing functions. The software supports functions such as voice dialing, SMS sending and receiving, dial-up networking, and data transmission.

4G modules are classified according to working frequency band:

4G private network module: refers to a 4G module working in a specific frequency band (1.4GHz or 1.8GHz). It is mainly used in specific applications such as electric power, government affairs, public security, social management, and emergency communications.

4G public network module: Simply speaking, it is a 4G module that works in non-private network frequency bands. It mainly includes two types – full Netcom 4G module and other frequency band 4G modules. The all-Netcom 4G module in China generally refers to the three-Netcom module that does not consider overseas and private network frequency bands, that is, a module that supports all 2G/3G/4G frequency bands of the three major domestic operators. 4G modules in other frequency bands generally only support modules in several specific frequency bands. The full Netcom module is highly versatile, but the cost is high. If you consider the cost or only bind it to one operator, you can also choose 4G modules in other frequency bands.

Classification according to chip solution:

Common domestic solutions include ZTE 4G modules, Huawei 4G modules, and Qualcomm 4G modules.

4G module application fields

4G modules are widely used in industrial fields such as electric power, industrial automation, environmental protection, and finance. Self-service terminal equipment requires large amounts of data network transmission. Through high-speed networking through 4G modules, all terminal business data and equipment operating status are transmitted to the business center in real time, reducing the operating costs of the business center and increasing the scale of management operations. In addition, 4G modules are also more widely used in various PLC remote control, PLC remote upload and download, PLC remote monitoring, etc.

The above is the introduction of 4G module manufacturers for you. I hope it will be helpful to you!
