Taiwan’s Chunghwa Telecom is deploying Nortel Networks’ radio, core switching and intelligent network equipment to upgrade its GSM network for GPRS wireless voice and data services. The upgrade will improve radio frequency (RF) coverage, prepare for seamless 2G/3G interworking, and provide a platform for new revenue-generating services like Personalized-Ring Back Tone, Prepaid Short Message Service, and others. The deployments are covered under agreements signed in June and August 2003 and collectively estimated at US$64 million.
