Factors that affect the effect of industrial 4g routers through
1. The wall effect of industrial routers actually refers to the size of the wireless coverage area. The wireless coverage is mainly affected by the wireless transmission power, gain, frequency band, and the wall material and thickness in the environment;
2. Wireless transmitting power of industrial router:
The good or bad effect of industrial routers through walls is largely related to the wireless transmission power of the router. In general, the higher the wireless transmit power, the better the wall penetration effect. However, it is clearly stipulated that the transmit power of the wireless router shall not exceed 100mW, and the electromagnetic radiation emitted by the router that exceeds this value will cause damage to the human brain and nerves;
3. Antenna gain of industrial wireless router:
If you want to buy a router that has a good effect through walls, you need to understand the wireless gain. In theory, the greater the antenna gain, the farther the signal travels. Common gains on the market are 3dBi, 5dBi or 7dBi. The larger the value, the greater the gain and the farther the transmission. However, the gain of the wireless router spreads linearly, and the larger the gain, the narrower the coverage area, so the antenna gain is not as large as possible.
4. Whether the 2.4Ghz frequency band or the 5Ghz frequency band:
Many wireless routers are in the 5G frequency band. So is it good for industrial routers with 5G frequency bands to penetrate walls? In fact, 2.4G is better than 5G in penetration. The advantage of 5G is that the transmission distance is farther than 2.4G, and it can transmit more information. If the space is relatively large, it is recommended that you buy a dual-band router (both 2.4G and 5G are supported).
5. Wall material and thickness:
If every wall in your house is a copper wall and iron wall filled with diamond cement, I'm sorry, no matter how good a router goes through the wall, it will not help. With two load-bearing walls in one gear, the signal will be attenuated even with high-power industrial routers. So when buying a router, you should know how many walls and load-bearing walls there are in your home. For large-area or duplex residences, ordinary routers + amplifiers/power cats may be a relatively good choice.
