Two classes of appliance control systems exist: inexpensive and costly. Low end = poor reliability and limited accessibility High end = high cost Needed: a system that provides high-end features while retaining a low cost.

Internet/ LAN Host Computer Links the host unit to the Internet. Host Unit Sends commands to the target units. Appliance Target Unit Receives and executes commands. Target Unit

Carrier Current Modem Signal attenuation Power line noise Power Supply Voltage Regulation Power Consumption

Signals attenuate when placed on a power line Signal level at receiver must be > 3 mV Line will contain noise that must be tolerated Signal-to-Noise Ratio must be > 15dB

Line length (m) Received signal voltage Applied signal = 71.5 kHz

0ms 2.5ms 5.0ms kHz 0kHz 200kHz 0.2V/div

Noise Received signal = 7mV RMS SNR = 19.5dB Bit error rate is less than the required 0.01% 60kHz 71.5kHz 80kHz Signal

Power supply has to Provide +5V and +10V Have a ripple of less than 0.5V PP Use no more than 3W Power supplies considered: Shunt regulator Series regulator
