You're welcome. As I read through the article, I see one "major" inaccuracy. It has to do with the description of the shift from analog to digital. The reality is that "ALL" radio signals are analog. The digital vs analog distinction is at the baseband level, not the physical layer.

I'll believe it when I see it. Hopefully it is.

For those wondering about why you can't simply get a software update to move frome one technology to another, it's due to a couple of key things. First, the frequency that the different technologies operate at drive the analog parts of the radio like the antenna, amplifiers, etc. The cond depends on the bandwidth of the signals and if the old system can receive the wider signals. Some of these things can be done using software defined radio implementations vs. Specific chips that implement a particular standard. That generally costs more, and won't overcome all the problems. Cell phones have multiple chip sets to provide multi-mode compatibility. The mass production of these chipsets is what keeps the cost/unit low.
