回頭看GSM，就我所知，制訂第一套規範至今，已經超過二十年，當然，一開始的analog規範及耗電、體積、價格等問題，到真正普及也是在1990左右
補充一下資料:
Martin Cooper talks about the first cell phone call.
April 3, 2003 marked the 30th anniversary of the first public telephone call placed on a portable cellular phone. Martin Cooper ( now chairman, CEO, and co-founder of ArrayComm Inc) placed that call on April 3, 1973, while general manager of Motorola's Communications Systems Division. It was the incarnation of his vision for personal wireless communications, distinct from cellular car phones. That first call, placed to Cooper's rival at AT&T's Bell Labs from the streets of New York City, caused a fundamental technology and communications market shift toward the person and away from the place.

所以大約是1973年左右, 比Apple II要早很多(Apple II是1987)
