EIRP (実効等方性放射電力) は、アンテナから出力される実際の信号量です。これは db での測定値であり、どの 3 つの成分に基づいていますか? (3つお選びください。)
正解:A,C,D
The radiated (transmitted) power is rated in either dBm or W. Power that comes off an antenna is measured as effective isotropic radiated power (EIRP). EIRP is the value that regulatory agencies, such as the FCC or European Telecommunications Standards Institute (ETSI), use to determine and measure power limits in applications such as 2.4-GHz or 5-GHz wireless equipment. In order to calculate EIRP, add the transmitter power (in dBm) to the antenna gain (in dBi) and subtract any cable losses (in dB). reference: https://www.cisco.com/c/en/us/support/docs/wireless-mobility/wireless-lan-wlan/23231- powervalues-23231.html
