Motorola Pageboy II was a pager and the successor to the Motorola Pageboy. ==General== The Motorola pager was a small radio receiver that delivered a message individually or widespread to those carrying the device. The first successful consumer pager was Motorola’s Pageboy I which was introduced in 1974. This type (without display) could not store messages, however, it was small, portable and notified its wearer that a message had been sent. By 1980, there were already 3.2 million pager users worldwide. At that time pagers had a limited range and were used mostly in on-site situations for example to call medical personnel in a hospital. By 1990, wide-area paging had been invented and over 22 million pagers were in use. Their number exploded and by 1994, there were over 61 million pagers in use. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Motorola Pageboy II」の詳細全文を読む スポンサード リンク
