The Software Defined Radio (SDR) Forum, a nonprofit international industry association supporting the advancement of reconfigurable wireless technology, has announced the creation of a worldwide task group on transceiver subsystem interfaces (TSI). Created under the umbrella of the SDR Forum Technical Committee, the new task group will be dedicated to facilitating industry convergence on open specifications supporting the interface between the radio frequency front end and baseband processing/modem subsystems in reconfigurable radio products.

The TSI task group's initial objective will be to expand upon the work done by the European End-to-End Reconfigurability program and other related efforts to define standard transceiver application programming interfaces (API) for use by radio equipment manufacturers in the commercial, public safety and defence domains.

As a part of this effort, the TSI task group will – to ensure support – evaluate the proposed transceiver API against the various lower-level transceiver interface specifications and standards that have been developed for the commercial and defence wireless markets over the past several years. This evaluation will include the Reference Point 3 specification developed under the OBSAI (Open Base Station Architecture Initiative), the DigRF Interface specification under development by the MIPI (Mobile Industry Processor Interface) Alliance, the VITA Radio Transport draft standard developed by the VITA Standards Organization as VITA 49, and the CPRI (Common Public Radio Interface). One important outcome of this activity will be the revised submission of the transceiver API in response to the OMG's (Object Management Group) Digital IF request-for-proposal for additional follow-on standardization.

The new TSI task group will formally launch at the SDR Forum's next general meeting, Jan. 14-17, 2008, in Tampa, Fla.
