IEEE published a new 802.1CM-2018—IEEE standard that supports fronthaul interfaces such as the recently published eCPRI specification to provide Ethernet-based fronthaul.
“As we see carriers and operators pursuing 5G technologies, and a wide range of new possibilities for next-generation mobile applications, IEEE 802.1CM represents a key pioneering step for providing reliable packet transport within 5G networks,” said Glenn Parsons, chair, IEEE 802.1 Working Group. “The standard’s development, in cooperation with multiple standards organizations, demonstrates how IEEE-SA is committed to work collaboratively and respond quickly to industry demand—in this case for packet-based fronthaul.”
