The gain degree of the antenna to the signal: The signal is emitted in an elliptical shape from the top of the antenna along a certain arc angle. Theoretically speaking, under the same transmission power, the higher the antenna gain, the farther the transmission range, and it has a close relationship with the transmission direction of the wireless signal. system. The unit of antenna gain is dBi. Generally speaking, the antenna gain of the home wireless router is about 5dBi, which means the configuration is relatively high. The general industrial enterprise-level router or outdoor router of 7dBi and above.
