What does the antenna interface mean?
The antenna interface refers to the antenna interface, which is an interface end of the wireless device.
Applicable Scenarios
The antennas of the wireless devices themselves have a certain distance limit. When the distance exceeds this limit, these external antennas must be used to enhance the wireless signal. To achieve the purpose of extending the transmission distance. There are three concepts involved here:
1. Frequency range It refers to the frequency band in which the antenna works. This parameter determines which wireless standard wireless device it applies to. For example, 802.11a standard wireless equipment requires an antenna with a frequency range of 5GHz to match, so when purchasing an antenna, be sure to look for the corresponding product with this parameter.
2. Gain value This parameter represents the antenna power amplification factor. The larger the value, the greater the signal amplification factor. That is to say, when the gain value is larger, the signal is stronger and the transmission quality is better.
3. Antenna interface is mainly for wireless devices that can be disassembled and connected to external antennas. Correctly match the corresponding antennas for different interfaces to increase the signal and extend the distance.
