It was called Aurora 400, the first form of cellular in North America. The down links were 419-422. High power mobiles were used or suitcase portable. It supported automatic dialing and incoming calls, but no tower hand off. You would learn the coverage of each site and know when to pull over, otherwise your call would drop when you switched towers.True, but if memory serves decades ago there was a mobile radiotelephone system out in
Alberta, which pre-dates AMPS (but might have been an early type of cell system),
using the 420/409MHz band.
