At that time, he stood on the streets of New York and called AT&T, which was also developing mobile phone technology. The latter was the world's largest communications company at the time, while Motorola was just a small company in Chicago at the time.
Martin Cooper said on the phone: "I'm calling you from a real handheld portable mobile phone."
However, due to obstacles in technology, commercialization and other processes at that time, this mobile phone has not been launched for a long time. The biggest obstacle is the construction of base stations.
It was not until September 21, 1973 that the Motorola DynaTAC8000X was officially launched, worth 3,000 pounds in the UK (approximately RMB 20,000 to 30,000 at the time).
The phone weighs 1 kilogram and takes 10 hours to fully charge, but it can only make calls for half an hour before running out of power.
