Transmission range is theoretical data derived from an ideal test environment. We list some influencing factors as follows:
Factor 1: Affected by the transmit power of the router
This is the decisive factor affecting the transmission range of industrial cellular routers. serial to wifi converter The higher the power, the wider the transmission range. However, according to Chinese regulations, the maximum transmission power shall not exceed 100mW, which is equal to 20dBm (2.4GHz frequency band). Because the greater the power, the greater the radiation. And it is harmful to the human body.
Factor 2: affected by the antenna
The high-gain antenna can increase the receiving distance. Gain is the power density ratio of the signal generated by the actual antenna and the ideal radiating element at the same point in space when the transmit power is constant. The higher the gain, the farther the wireless radiation distance.
Factor 3: Affected by terrain and obstacles.
The deployment environment of industrial cellular routers is complex and changeable. serial port ethernet converter In this case, it will be difficult to achieve the ideal wireless transmission range. Among these influencing materials, walls and glass barriers have the greatest influence on the signal.
Factor 4: Affected by weather changes
Industrial 4G routers with Ethernet are different from commercial or home routers, which are mostly installed outdoors and face a lot of environmental challenges. For example, in a thunderstorm, as the relative humidity in the air increases, the transmission range of the router will become narrower and narrower. The harsh outdoor environment also puts high demands on the oxidation resistance and protection of the chip.
In a word, it is best for users to choose an industrial cellular router with suitable power and gain antenna according to their own needs, try to use it in an open place, and maximize the transmission range of the router.
