#accaddeoggi 3 aprile 1973: la prima telefonata da un cellulare

Martin Cooper telefona al collega e rivale John Engel

Se la Bell System fu la prima azienda ad investire nel settore, la Motorola ebbe il merito di puntare a realizzare uno strumento portatile di comunicazione destinato ad un’ampia fascia di popolazione.

Il progetto, affidato all'ingegnere Martin Cooper, portò alla nascita di un dispositivo dai costi, tuttavia, esorbitanti.

Il 3 aprile del 1973 fu il giorno della verità: Cooper scese in strada con il proprio apparecchio e, per togliersi una grande soddisfazione, si recò nei pressi della sede della Bell. Qui si mise in contatto con l’azienda concorrente, nello specifico con il collega John Engel, a cui comunicò con orgoglio di trovarsi in strada e di stare utilizzando un telefono senza fili.

Questa chiamata, goliardica nella sostanza, portò all’inizio di una nuova epoca, quella della comunicazione a distanza.

Certo, sarebbero dovuti passare altri dieci anni perché la Motorola procedesse alla vera commercializzazione di un proprio modello, ma questo piccolo passo diede il via a quella rivoluzione mobile che si è protratta fino ai nostri giorni.

Sempre in contatto: storia sociale del telefono cellulare
