How to enhance the wireless signal of 4G industrial router?

Nowadays, 4G industrial routers are widely used, and many problems have been encountered in practical use. One of the questions often asked is how to ensure the good signal strength of 4G industrial routers. There are also many ways to find the best signal on the Internet, but it is a little different for fixed and network locations. So here are the Five Secrets of how we can ensure that 4G industrial routers have good signals.

1. Conduct coverage surveys. We know the location. The first step is to check the online coverage to see the services available in the area. With some online tools, you can get real-time information about where the coverage is and where the mobile tower is located. This helps identify the right mobile operator for a particular location.

2. Proper antenna placement. The placement of industrial routers and antennas is essential, which will be optimized according to the site layout during installation. Although traditional network routers can also be equipped with SIM card slots for wireless connection, these industrial routers are placed in the rack. Inside the server room, which makes this usually a meaningless exercise. It is essential to find accessible areas, close to windows, etc. This signal is very strong. There are special tools, but anyone with a mobile device can try this.

3. Use multiple networks. Although most mobile phones / tablets do not have this option, most excellent 4G industrial routers not only have two SIM slots, but also two industrial DTUs that can operate two signals and connections independently. This protects users from "cell breathing" and cell overload, so that the network tower itself reduces signal or throughput because it balances users and traffic. By being able to connect multiple towers and operators at the same time, routers can connect to the best towers.

4. Take it outside. For most places outside the metropolitan area far away from the network tower, it is not necessary to place equipment and antennas inside. The correct step is to move them outside. For these cases, the topographic survey helps to calculate the specific distance, terrain layout, obstacles, and calculate the correct antenna model and placement angle to achieve the best connection.

5. Use signal amplification equipment. When a remote site uses an external antenna, it can use the second method, the signal amplification device (intensifier), which is an additional device between the antenna and the router. It can clean and amplify the signal before transmitting the signal to the industrial router.
