A major contributing factor to this improvement is the planned deployment of CDMA 1X Advanced. This CDMA upgrade is expected to improve the reach and overall performance of CDMA radio signals, while providing landline quality voice service. In-building coverage should improve as a result of repurposing a portion of iDEN spectrum (800 MHz) for CDMA services, giving customers the benefit better coverage and quality inherent with 800 MHz spectrum. The transition to a multi-mode platform provides the opportunity to offer devices with integrated chipsets that can receive radio signals from multiple frequencies.
