Personal Digital Cellular

Personal Digital Cellular (or PDC for short ) was a cellular standard that was used exclusively on the Japanese market, where it was developed. Like GSM , it was classified as belonging to the second generation of mobile communications standards. At its peak, the system had 80 million participants.

The standard was set in 1991 by the Japanese TV standardization organization ARIB . It used the frequency bands 800 MHz and 1.5 GHz and supported voice transmission and services such as call waiting, forwarding and voice mail. In addition, data transmission of up to 9.6 Kbit / s was possible. On March 31, 2012, NTT DoCoMo was the last operator to stop the service.
