質問 118
The signal strength I Mean RSSI displayed by the wireless device can directly reflect the quality of the link, but the actual noise floor is related to the environment and interference and will change from time to time. While the RSNR is relatively stable (for a fixed environment and transmit power), It can be considered to be related to the transmission power, the antenna used by the equipment, the distance of the equipment, the space attenuation, etc., but when the equipment is installed, the RSNR is often relatively fixed.
The following description of the relationship between noise floor and I RSSI, which is correct?
- A. In a fixed network, if the noise floor increases, the RSSI will decrease, otherwise, if the noise floor decreases, the RSSI will increase.
正解: A
