Factors affecting the coverage of industrial 4G routers and adjustment methods

The maximum distance that a general wireless router can cover is usually 100 meters to 300 meters. However, it is difficult to reach the theoretical value for the wireless signal distance of many wireless 4G routers after testing. So what are the factors that affect the coverage of industrial 4G routers? How to adjust the coverage range?

1. Environment

The signal coverage of the 4g industrial router in an open environment will inevitably be wider. If there is interference from water, signal interference sources, metal objects or walls in the transmission environment, it will inevitably affect the signal of the 4g industrial router. The result of the effect depends on how much the interfering substance affects the signal. For example, the thickness of the wall in the transmission medium or the wall material has different effects on the signal coverage.

2. Antenna

The length of the antenna, the stronger the signal, the wider the signal, or the number of antennas is also an important factor affecting the coverage of the WIFI signal. Otherwise, you will not see 4g industrial routers with 3 or 5 antennas on the market.

At the same time, the antenna quality of the 4g industrial router is also the key. The high-quality 3dBi antenna can achieve high gain signals, and the wifi distance can reach more than 100 meters.

Adjustment:

(1) Adjust the antenna: Since the antenna affects the coverage of the 4g industrial router, choose a rod antenna or a full-frequency suction cup antenna, choose a small business antenna or a 5dBi antenna such as ZTE, and the number of antennas are all covered by the 4g industrial router The range can be expanded and adjusted to varying degrees.

(2) Networking mode: If Wi-Fi signal coverage is not good, signal blind spots often occur, the usual measures are to switch to high-power wireless routers or use Wi-Fi relays, that is, networking mode to achieve coverage adjustment.

Industrial-grade 4G router is a high-end communication device that can withstand complex environments. It is widely used in high-end fields or outdoor engineering work. With its many advantages, it can realize high-speed and stable data processing by industrial equipment. As an industrial-grade router, in many respects, it is more powerful than ordinary household routers. Generally speaking, the well-known industrial-grade 4G router has the following advantages in the process of use.

1. High stability

Industrial-grade 4G router has high stability when transmitting and receiving data is one of its main advantages. It uses high-performance industrial-grade wireless modules and industrial-grade high-stability and high-precision components, which can make it resistant to harsh outdoor environments without interruption or loss of data transmission.

2. Fast data transmission and processing

Compared with general routers, industrial-grade 4G routers use high-performance CPU processors, so its data transmission and processing speed is several times that of general routers, which can satisfy more people connecting to the network at the same time, and the transmission distance is longer. The far coverage is also greater.

3.with powerful functions

Advanced industrial-grade 4G routers have more powerful functions than ordinary routers. For general household routers, the function is simple as long as it can connect to the network normally. But for the industrial control industry, routers need more functions to meet normal operation. Industrial-grade 4G routers have corresponding functions to meet the needs of different fields. If you need other special functions, you can also choose customized products.

Industrial-grade 4G routers have high stability, fast data processing speed and powerful functions are its main advantages. In addition, it provides a large number of ports and powerful wireless signal reception capabilities are also its own advantages. Because industrial-grade 4G routers are often used in high-end fields or outdoor complex conditions, it must have more functions and advantages to meet people’s needs.
