September 6th, 2007
Pernah penasaran bagaimana GSM dan CDMA bekerja?
Simaklah artikel berikut..
“(On Screen): As I think many of my readers know, I used to work for Qualcomm designing cell phones. Qualcomm is the company which invented CDMA, and made it practical, and made it into a market success, and it now dominates the American market, where Verizon and Sprint both use it. There are two other nationwide cellular systems: AT&T currently uses IS-136 TDMA, which is obsolete and has no upgrade path. Cingular uses GSM, a more sophisticated form of TDMA from Europe.”
