From the user's perspective, the mobile experience starts with the speed at which the device receives data and applications. That speed is the combined result of the speed capability of the modem technology inside the device, which is fixed, and the speed capability of the infrastructure, which can vary.
Thus, wireless speed is a complicated component to measure. So complicated, in fact, that the Mobile Technologies Index breaks it into two components, each with its own metric:
This article provides our forecast for device connectivity speed, explaining the metric and how we calculate it, and explores some implications for mobile innovation.
PwC forecasts a compound annual growth rate of 37% for average aggregated device connectivity speed as measured in Mbps/$ through 2015. Put another way, average aggregated device connectivity speed will be four times greater in 2015 than in 2011.
