På sid 30 står om Nhu's käpphäst spectrum crunch; behovet av bandbredd överstiger snart tillgången på frekvenser om man inte bl a massivt introducerar olika former av femtoceller som radikalt minskar sektorstorlekarna och medger återanvändning av spektrum.
“The explosive growth in mobile communications is outpacing our ability to keep up. If we don’t act to
update our spectrum policies for the 21st century, we’re going to run into a wall -- a spectrum crunch --
that will stifle American innovations and economic growth and cost us the opportunity to lead the world in
mobile communications,” stated FCC Chairman Genachowski as the commission issued a report on
October 20, 2010, that detailed the “looming spectrum crunch.”29 Some of the key findings of the report
included the following:
The spectrum deficit is likely to approach 300 MHz
This spectrum crunch will be driven by significant growth of mobile broadband traffic, on the order
of 35 times recent levels
Mobile broadband growth is likely to likely to outpace the ability of technology and network
improvements to keep up by an estimated factor of three
Meeting this need may create US$120 billion in spectrum value, with hundreds of billions more in
total value to the economy
