Citigroup questions if there really is a US spectrum shortage for mobile

As I wrote before, the USA/Canada mobile market is ruled by corporate interests. One of the myths is that there is a shortage of "spectrum". This gave way to auctions for spectrum. In turn this means that different companies make handsets that run on different frequencies, and the balkanization of the market, or prices going up as phones become multifrequency.

Now, Citigroup questions if US spectrum shortage is real.

Hope Canada listens too.
