Personal Digital Cellular
PDC is the Japanese digital cellular standard. It will enhance the capacity limitations that were previously experienced by analog systems, as new spectrum has been
made available for PDC.
The use of the new digital technology is aimed at
increasing competition and expanding cellular phone service to more users in
Japan.
The Japanse PDC system operates in the 1880 MHz to 1900 MHz
band, the same band as used by the DECT standard which originated from Europe.
The introduction of a 1.5 GHz version of PDC in the Japanese market enables new
operators to compete in the cellalar market.
