Meh, a lot of people predicted this. Two-way communication via radiowaves had been a thing for decades by this point and the first commercial transistor radio was already in development and would be released shortly. It was not a stretch to think that personal, cordless phone service could be provided by a two-way transistor radio. Edit: according to wikipedia, AT&T had developed and deployed car-based mobile phones in the late 1940s. So yeah, definitely not much of a "prediction" seeing as a phone executive would have been well aware of these developments.
