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 312 Mbit/s can additionally handle
