A working group is an interdisciplinary collaboration of researchers working on new research activities that would be difficult to develop under traditional funding mechanisms . The lifespan of the WG can last anywhere between a few months and several years...

 in April 2007. The group is focused on developing specifications for wireless mobile RFIC to base-band IC (BBIC) interfaces in mobile devices.

The group's current charter is split into short and long term development efforts. The short term development will focus on a specification targeted for completion by end of 2007 for LTE
3GPP Long Term Evolution
3GPP Long Term Evolution, usually referred to as LTE, is a standard for wireless communication of high-speed data for mobile phones and data terminals. It is based on the GSM/EDGE and UMTS/HSPA network technologies, increasing the capacity and speed using new modulation techniques...

 standards. The longer term development will focus on future air interface standards which promise further improvements in high speed, data optimized traffic. In addition, the future work will seek to harmonize efforts with the MIPI's PHY
PHY
PHY is an abbreviation for the physical layer of the OSI model.An instantiation of PHY connects a link layer device to a physical medium such as an optical fiber or copper cable. A PHY device typically includes a Physical Coding Sublayer and a Physical Medium Dependent layer. The PCS encodes and...

These specifications will describe the logical, electrical and timing characteristics of the digital RF-BB Interface with sufficient detail to allow physical implementation of the interface, and with sufficient rigor that implementations of the interface from different suppliers are fully compatible at the physical level.

There is DigRF version v1.12 for usage in GSM/EDGE handsets, which was specified in 2004. DigRF v3.09 from the year 2006 with its 312Mbit/s can additionally handle UMTS. Present DigRF v4 draft offers Gbit/s bandwidth for LTE and WiMax.
