METHOD FOR INCREASING OUTPUT POWER OF TRANSMISSION SIGNAL FROM DEVICE, METHOD FOR INCREASING OUTPUT POWER OF SIGNAL TRANSMITTED IN FREQUENCY BAND INCLUDING A PLURALITY OF SUBCARRIER FREQUENCIES, AND NETWORK ADAPTER

摘要

PPROBLEM TO BE SOLVED: To increase an output of a signal transmitted on a wired communications network such as a PLC network without making the output exceed the maximum allowable common-mode (CM) current specified by a regulatory organization. PSOLUTION: A network device is first tested for regulatory organization's compliance on a standard network. An output voltage of the device is adjusted until the maximum allowable CM current is detected, and this voltage level and the CM current are recorded and stored in non-volatile memory of the device. The device is then connected to an actual network and the output voltage is set to a previously recorded value. At this voltage level, the CM current in the actual network is measured and recorded. The difference between the CM current measured by the device on the actual network and the maximum allowable CM current is calculated and used to calculate the amount of the output power of the signal from the device can be increased without making the output exceed the maximum allowable CM current.
