Interesting article. Very near the front is a patent inaccuracy:

"Probably the most well-known mixed-mode operation occurs in
police vehicles, where data is squirted across to the patrol car
on voice channels. The data is usually information about a person,
a vehicle, or a location and is displayed in a small screen in the
cruiser."

Please don't tell that to my public safety communications clients
who all use separate dedicated channels for voice and data, albeit
in the same general frequency range. It will only confuse them....
