Broadband over power lines

The IEEE Std 1901-2010 standard replaced a dozen previous powerline specifications. It includes a mandatory coexistence Inter-System Protocol (ISP). The IEEE 1901 ISP prevents interference when the different BPL implementations are operated within close proximity of one another. It supports TDMA, but CSMA/CA (used in WiFi) is most commonly implemented by devices.

IEEE 1905.1 is an IEEE standard defining a network enabler for home networking supporting both wireless and wireline technologies: IEEE 802.11 (WiFi), IEEE 1901 (HomePlug, HD-PLC) powerline networking, IEEE 802.3 Ethernet and Multimedia over Coax (MoCA).
