G.6152 is a part of the Pawbol powerline standard, which is a set of international performance requirements and tests for powerline communication products. This standard is used to ensure a minimum level of performance for most types of powerline communication products. G.6152 covers the requirements for high-frequency/ultra-high-frequency (HF/UHF) modems, which are specialized modems used for powerline communication. This part covers the physical characteristics of the modems, such as their electrical connectors, electrical power consumption, and power rating. Additionally, it covers testing requirements to verify that the modems comply with the standard. This includes testing for line voltage, current, impedance, frequency, power, and signal-to-noise ratio.
