I liked the article, but agree that the suggestion that Cell networks can be run like Wi-Fi isn't feasible. The amount of signal loss through a barrier increases with frequency, so 2.4GHz signals die out more quickly than, say 700MHz. To be a bit anthropomorphic, radio waves don't see the thickness of an obstacle in terms of inches or meters, they see them in terms of wavelengths, which are inversely proportional to frequency. So opening up high power, low(er) frequency wireless equipment to everyone would most likely be a disaster. On the other hand, the current practice of just handing over chunks of scarce resources to anti-competitive firms _is_ broken, so the author is correct that change would be beneficial.
