In this time of monumental change in the M2M world, it is a good moment to take a step back and reflect upon what got us where we are today. This is a great article from a 1931 edition of National Radio News. It provides a technical overview of one of the police radio transmitter systems for the Michigan State Police. The author, J.A. Dowie notes:
“…where the police radiotelephone transmitter is located, it formerly took the telephone operator from one to two hours, frequently longer, to call all the sheriff’s offices, municipal police departments and State police detachments to give them important information on an emergency call such as a bank robbery, State penitentiary or State asylum breaks. Such information can now be transmitted in a few seconds or a fraction of the time formerly required.”
