IEEE 802.7 is not one of the more widely recognized standards within the IEEE 802 series, which primarily deals with local area and metropolitan area networks. As of my last training data in September 2021, IEEE 802.7 pertained to a Broadband Technical Advisory Group (TAG). This TAG was responsible for advising on broadband technologies, but it wasn’t a specific standard like IEEE 802.3 (Ethernet) or IEEE 802.11 (Wi-Fi).
It’s worth noting that while some IEEE standards become globally recognized and widely implemented, others may serve niche roles or advisory purposes and may not become as popular or well-known outside of specialized areas of the field. If you have a specific question or if you’re referring to a newer standard or revision post-2021, I’d recommend checking the official IEEE website or other authoritative sources for the most up-to-date and detailed information.
