Abstract
A wireless power line carrier data communication device is provided. The device is specifically adapted to meet the requirements of high-speed modem data transmission, such as is typically required by digital computer networks and similar devices. The device employs an improved power line transmitter power output which reduces the effect of harmonic distortion and also employs a bit-stream sine wave generator with a digital to analog converter to producing a sine wave for the sub-audio carrier signal, which also reduces the effects of harmonic distortion. The device is specifically designed for data transfer over the AC power lines and is compatible with standard AC power signals as well as standard modem equipment and standard telephone connections.
