# Lahirnya Telepon Selular
Konsep teknologi seluler telah dibuat oleh saingan Motorola, AT&T, yang Bell Labsnya memperkenalkan sistem yang memungkinkan ponsel bisa digunakan dari tempat yang satu ke tempat yang berbeda tapi tetap berada di saluran yang sama. Tetapi AT&T memfokuskan teknologi ini pada telepon mobil.

Cooper kemudian ingin orang memiliki kebebasan untuk berbicara di telepon jauh dari mobil mereka. Jadi sebagai reaksi, dia dan Motorola memulai proyek untuk membuat perangkat yang lebih portabel.
Motorola menghabiskan waktu tiga bulan membangun prototipe untuk handset mobile portabel yang ditunjukkan Cooper secara terbuka pada bulan April 1973. Ponsel komersial pertama perusahaan, "DynaTAC," mulai dijual 10 tahun kemudian.
