Summary

SPE, either stand-alone (data only) or together with power, offers numerous opportunities in building automation. Until the ecosystem is fully developed, however, there is still a need for media or protocol converters to upgrade existing systems, as well as challenges associated with the reuse of existing cables (unshielded, no twisting, wire gauge) and connectors, which may not offer the full distance or speed as defined in 802.3cg. But this will not be a major hindrance, as the future benefits outweigh the constraints. Power-sourcing equipment and power-delivery devices for SPE are expected to be released in the coming years; until then, an engineered link will power devices at the edge. You can also expect to see building automation products supporting SPE with seamless integration.
