•The first company was Motorola, with the DynaTAC 8000x. It weighed 2 pounds, earning the nickname “The Brick”.
•Designed by Rudy Krolopp.
•Took 10 years, and over 100 million dollars to develop.
•It received FCC clearance in 1983
•13 inch x 1.75 inch x 3.5 inch in size
•One hour of talk time and eight hours of standby time
•The original price was 4000$.
•These cell phones were most commonly used in businesses or travel or important things. The brick was expensive, so the average person couldn’t afford such a thing.
•Calling distance is the same even today. You have to have cell sites to call. Each cell phones provider has a network of bases or cell sites, to transmit the call through radio waves.
