A radio equipment comprises waveform generator to receive input data and to generate output baseband waves corresponding to the received input data, and a radio-frequency component to transform the baseband waves generated in radio waves. The waveform generator comprises a Radio Virtual Machine (RVM) that has been compiled to operate on hardware underlying the RVM. The RVM comprises an associated RVM class that establishes a level of reconfigurability of low-level parameters of the RVM. The RVM class comprises one of a plurality of RVM classes in which each RVM class comprises a corresponding level of reconfigurability of low-level RVM parameters and a corresponding level of certification testing for reconfigured RVMs of the class. In one exemplary embodiment, the plurality of RVM classes comprises at least one RVM class comprising full reconfigurability of low-level RVM parameters and at least one RVM class comprising limited reconfigurability of low-level RVM parameters.
