Abstract:
1. A transmission method applied to a system comprising transmission media and a plurality of transmitter-receivers connected via the transmission media, comprising: transmitting information on the output power of a first transmitter-receiver from the first transmitter-receiver to a second transmitter-receiver; measuring reception strength by the second transmitter-receiver when the second transmitter-receiver receives the output power information; reading the output power information by the second transmitter-receiver; and comparing the reception strength with the output power information to calculate a transmission loss or gain by the second transmitter-receiver, wherein at least one of the transmission rate and the output power of the first transmitter/receiver are automatically adjusted according to the calculation of transmission loss or gain by the second transmitter-receiver, wherein the output power for transmitting the output power information is expressed as follows: where B
