The Concpet
Software defined Access is a part of NFVAllows cellular network administrators to manage their access services and cell site baseband resources more easily through abstraction of the L1 functionality into virtual routines This replaces having to manually configure and deploy hardware based L1 processing. SDA has become more important with the emergence of Cloud RAN in which a cellular network uses a centralized or regional Server Farm to process all or some of its cell site traffic at the L1 level.

SDA decouples the specific hardware of a given cell site and/or Cloud RAN baseband resource pool (the data plane – L1) ,from the upper stack software and signaling management (the control plane – L2 and up)

The inventors of SDA claim that it will mitigate vendor interoperability risk ,and enable advanced network features such as : CoMP, Massive dense networks, etc

The Players
ASOCS will introduce at Linley Carrier conference on June 12th 2013, a software framework called Modem Processing Language (MPL) to enable decoupling , programming and virtualization of baseband resources
