¿Qué es la computación de borde (MEC)?
Jan，4 2021
¿Qué es la computación de borde (MEC)? Para evitar la torpeza de la tecnología, déjame darte un ejemplo. Hay un animal muy inteligente en la naturaleza: el óvalo. Tiene el coeficiente intelectual más alto entre los invertebrados. Ya sea para escapar o depredar, tiene muchos tentáculos largos que pueden ser usados libremente. Los científicos han descubierto que los tentáculos del pulpo están llenos...

Calculation of antenna gain
Dec，29 2020
Calculation of antenna gain Expected to finish reading in 10 minutes Gain refers to the ratio of the power density of the signal generated by the actual antenna and the ideal radiating unit at the same point in space under the condition of equal input power. It quantitatively describes the degree to which an antenna concentrates input power to radiate. The gain is obviously closely related to the ...
