Chapter 4 Introducing the Web Configurator Table 9 Summary: My Homeplug Network LABEL DESCRIPTION Avg. Attenuation This field displays the average attenuation measured in dB. Attenuation is the reduction in strength of a signal as it travels over a transmission line. Use this field to check the reduction in the strength of the signal between two devices. Attenuation may vary considerably across a powerline network as line conditions also vary. A typical level of attenuation may be 40 dB, but may reach over 70 dB, depending on line quality and distance. A main cause of attenuation is the power requirements of appliances on your electrical circuit. Powerline traffic near an appliance such as a refrigerator may be affected by attenuation more than on other sections of your powerline. Avg. Output Power This field shows the average power produced by the device. Power levels should be constant and limited by the output power standard of your country. Unusually high output power levels may damage your device. PLA450 User's Guide 45
