Full title: IEEE Standard for Local and metropolitan area networks — Time-Sensitive Networking for Fronthaul
This standard defines profiles that select features, options, configurations, defaults, protocols, and procedures of bridges, stations, and LANs that are necessary to build networks that are capable of transporting fronthaul streams, which are time sensitive.
IEEE Std 802.1CMTM supports fronthaul interfaces, e.g., the eCPRI specification to provide Ethernet-based fronthaul. IEEE Std 802.1CM has been developed in collaboration with the CPRI Cooperation that contributed the requirements towards a fronthaul transport network. IEEE Std 802.1CM describes how these requirements can be met by a fronthaul bridged network including synchronization solutions developed by ITU-T Question 13 of Study Group 15 whose input also contributed to the development of IEEE Std 802.1CM.
IEEE Std 802.1CMTM-2018 is the first IEEE standard developed to connect a cellular network’s radio equipment to its remote controller via a packet network, in particular, via a bridged network over IEEE Std 802.3TM Ethernet. See more in the press release.
An overview presentation may be good to get started.
