CC2530的传输距离怎么算？

老板让我算一下CC2530和CC430的理论传输距离各多少？

传输距离跟很多因素有关的，发射功率，接收灵敏度，环境，天气等都有关系。

•How far can TX and RX be apart from each other?

•Friis’ transmission equation for free space propagation:

              or

•

–

–Pt is the transmitted power, Pr is the received power

–Gt is the transmitter, Gr is the receiver antenna gain

–d is the distance between transmitter and receiver, or the range

–Lambda is the wavelength
