摘要
A method for analyzing quality of indoor radio wave propagation using variable signature sequences in a construction comprises the following steps: a first measurement device at a first location inside the construction transmits a first test packet, a digital signal having a first length; the first measurement device transmits a second test packet having a second length longer than the first length if the first measurement device cannot receive a response signal to the first test packet from a second measurement device in a reference time period; the second measurement device at a second location inside the construction receives the second test packet and transmits an echo-back packet, which is a digital signal in response to the second test packet; and the first measurement device measures the quality of a current communications channel based on the echo-back packet.;COPYRIGHT KIPO 2016
