The new 3G system being installed uses protocols developed as an extension to the GSM system, but the underlying transmission is wideband CDMA (WCDMA) as Don stated above. As such, the cell coverage should approximate that achieved with the present CDMA system. There will be a considerable number of new base stations installed, so the overall coverage will increase.
