Paper on innovation in mobile service industry.

Found this interesting paper titled “Innovation and Schumpeterian Competition in the Mobile communication services Industry” detailing on the play of creative destruction in the mobile communication industry. One thing that I do’nt fully agree is the definition of innovation in this context as introduction of a new “tariff plan”. It is a too narrow definition because It inherently makes the assumption closed network, i.e tightly controlled supply side, but whereas we have seen that big scale disruption happened when supply side opened up massively ( i-mode) , basically an end to end network.
Well that made me think what could be the defintion of innovation could be that would also serve as a superset definition to tarriff plans ??
