Mobile phone users in Vietnam are going to have a new mobile phone network to be put into operation in June of 2005.
The prime minister recently approved a joint-venture project between Hanoi Telecom Co and Hutchison Telecom S.A.R.L. to set up the network, the director of the Hanoi Telecom Trinh Minh Chau confirmed.
The Code-Division Multiple Access (CDMA) technology mobile network has an initial investment capital of US$630 million, with a target of 2.9 million subscribers in the first ten-year period.
The network uses digital cellular technology that employs spread-spectrum techniques. Unlike GSM, which uses TDMA technology, CDMA does not assign a specific frequency to each user. Instead, every channel uses the full available spectrum. Individual conversations are encoded with a pseudo-random digital sequence.
With the new mobile network, Vietnam is to have three CDMA technology mobile network providers, including S-Fone, VP Telecom, and Hanoi Telecom.
