DrQuine is absolutely right on here. Over the past few years, I haven't seen much change in the cost of Internet access, but that access has improved dramatically for the same cost. Where I do notice a difference is "on the road", where the quality of access has improved dramatically over that same period of time without a noticeable increase in cost. With some many places offering "free" wi-fi, having reasonably high speed access while out and about is almost expected today.

The killer application is improved affordability. While the providers seek to increase their profits, the users are looking for affordable alternatives. It may be the "Innovator's Dilemma" but the providers need to be thinking about what would happen if the cost of internet access dropped 90%. How would they survive? Then act accordingly before a start-up competitor does.

Providing data synchronization capability, any OS suppliers seem to be a a logical choice for most people. Microsoft provide Cloud data storage service. Apple has iCloud. Ubuntu and Ubuntu One. What would be the next value added service that would be logically better tie to Wireless Service Provider?

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
