Quick Note: Vodafone CEO Says Only "Technofreaks" Want 4G

He said normal, everyday people wouldn't notice a difference between 3G and 4G
Vodafone's CEO referred to 4G connectivity as a feature that only "technofreaks" are worried about.
Vodafone CEO Vittorio Colao discussed how UK digital communications company EE's 4G network has impacted
Vodafone's business in the UK
during a media conference call earlier this week.
According to Colao, customers wouldn't notice a difference between 3G data speeds using HSPA+ and 4G network speeds -- hence, 4G isn't a necessary network feature.
“I haven’t seen any figures but when I visited an EE store to see how fast it was all I saw was technofreaks in there," said Colao. "I haven’t heard any calls from friends, colleagues of businesses that we need this fast internet. With the increase in data speeds of HSPA+ (a faster version of 3G), an early LTE network won’t be much different.”

You are absolutely wrong about this.
Wireless spectrum is a scarce resource. People have been battling over the right to use various spectral bands since the 50s. This heated up in the 90s when the U.S. Congress realized that auctioning off the right to use specific radio frequency (RF) spectra in a given reason could be an income source. Since then companies have spent billions and billions on licenses to specific spectra.
AND all that spectrum use must be coordinated. This is the job of the FCC and NTIA in the U.S. along with regional spectrum managers for occasional users.
AND the amount of information you can get through an RF channel *IS* limited. Have you never heard of Shannon's Limit? If not, look it up. You can only push so much information through a given channel.
It really does not matter how much money you throw at the problem there is a limit. DARPA right now is soliciting proposals to figure out how to get 20 bits per Hz of spectrum continuously to known users over long distances and in real world conditions. This is considered a "DARPA Hard" problem. It's pretty cutting edge.
Sure, LTE-A claims *up to* 30 bits per Hz of spectrum, but that is for very short distances and only under the most optimum conditions. LTE-A will not give that kind of throughput to the average user under typical, real world conditions. Then what's next?
If you think you can meet or beat the 20 bits/Hz that DARPA is requesting over long haul distances then put in a proposal for $20 million and get rich.
Spectrum and the information that can be pumped through it are NOT infinite or even abfinite. It is not only finite; it is scarce. Pretty much everything under about 25 GHz RF is already spoken for (licensed) in the U.S. Once you start going higher atmospheric effect really get in the way. At 60 GHz the atmosphere is almost a slightly translucent wall, RF speaking.
So unless you have some way to magically exceed Shannon's Limit and have as much information throughput as you want under all conditions and distances, you should sit down, shut up and let those of us who really know what is going on move technology -- and RF information throughput -- forward as fast as we can.
