I realize that there is probably a whole lot of wireless traffic, and that it is increasing. But to presume that Moores law will apply to something that is limited by physics is a bit of a stretch. It did apply to manufacturing, which is a bit different. My feeling is that these "market predictions" are actually what the marketing people want it to be, rather than valid numbers based on any reality. Besides that, there is only so much spectrum, they are not making spectrum any more. Yes, we can always go to a higher frequency, but physics makes that more difficult as well.

@dirk.bruere: the number seems a bit small to me as well for wireless traffic. The wired traffic is already many orders of magnitude higher (elsewhere on EE Times forum I posted traffic data in major internet exchanges already crossing TB/sec). It is clear to me that the content demanded by smart phones and tablets will be more data-intensive as the world adopts more of 4G-wireless services. The data traffic by M2M nodes will be far less and is not the major demand for increased data traffic. MP Divakar

600TB per month? Sounds very low. Sure that should not be PB?

Moore's law will be required to be applied to the bandwidth usage now, what he has said for the usage of transistors in the ICs is going to be true for bandwidth usage in wireless. In my opinion Agilent is having quite right step further in formulation of strategy.

LATEST ARCHIVED BROADCAST
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.
