Coverage of Industrial 4G Routers

Factors affecting the coverage of industrial 4G routers and how to adjust them

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

1: Environment

In an open environment, the signal coverage of 4g industrial routers is bound to be wider. If there is material interference such as water, signal interference sources, metal objects or walls in the transmission environment, it will inevitably affect the signal of 4g industrial routers. 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 material of the wall have different effects on the signal coverage.

2: Antenna

The approximate length of the antenna, the stronger and wider the signal, or the number of antennas is also an important factor affecting the coverage of the WIFI signal. Otherwise, there will be no 4g industrial routers with 3 or 5 antennas on the market.

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

  Adjustment:

(1) Adjust the antenna: Since the antenna affects one of the factors that affect the coverage of 4g industrial routers, 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 for 4g industrial router coverage The range can be extended and adjusted to different degrees.

(2) Networking method: If the Wi-Fi signal coverage is not good, there are often dead spots in the signal. The usual measure is to switch to a high-power wireless router or use a Wi-Fi relay, that is, the networking method 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, industrial equipment can process data at high speed and stably.
