Mobile network lifecycles--and return on investment--have been getting steadily shorter in the digital age. Analog first generation mobile networks had a 15-year lifecycle. Some would argue 4G has had just a five-year cycle before development of the next generation got underway.
That seems excessively short. The usual rule of thumb about mobile network generations is that they last about 10 years each.
Disintermediation (removing intermediaries in any value chain) does not help, either.
