[ns] the formula(way) to convert from w to m(meter)
Hello, For using the transmission range,receiving range,..., it is difficult to imagine if using w unit. -Does anyone has the formula to convert from w to m(meter) or an easy way to imagine : - transmission range from w to meter? e.g 8.5872e-4 w ~ 40m the power consumption for transmission from w to meter? - power consumption for reception from w to meter? - idle power consumption from w to meter? - sleep power consumption from w to meter? - receiving range from w to meter? - carrier sensing range from w to meter? Thank you in advance!
