What we're working on

The past 12 months our members have produced major evolutions of the FAPI specifications for the 5G Era, 5G nFAPI specs which address Split 6 option, allocating network functions for a disaggregated RAN, small cell product definitions for 5G, foundational documents for private cellular networks and the role of small cells in Edge, how AI and ML are transforming network planning and the tools for the management of dense networks. Our new work plan builds on these outputs to support the deployment of agile, low-cost mobile infrastructure through small cells. Watch this video to find out more.
