Interoperability
HomePlug AV, GP and AV2 are fully interoperable, and will also interoperate with the IEEE 1901 devices. HomePlug 1.0 devices do not interoperate with HomePlug AV devices. Although it is technically possible to achieve such backward compatibility, doing so is not economically feasible because of the high cost of circuitry that would have to support different Forward error correction (FEC) techniques and feature sets.
HomePlug devices will not interoperate with devices that employ other powerline technologies, such as UPA, HD-PLC, or G.hn. In the case of G.hn, it was deemed prohibitively expensive to implement both HomePlug's turbo coding forward error correction and G.hn's low density parity check (LDPC).
HomePlug devices are not compatible with certain power strips, surge protectors, and uninterruptible power supplies incorporating filters, which block the high-frequency signal. In such cases, the installer must plug devices directly into building electrical receptacles.
