CDMA2000 1X: Should You Deploy?

Can You Afford Not To Deploy?

!Double voice capacity - gains in voice servicesalone support migration to 1x

!Capitalize on Revenue-Generating 3GCapabilities

!Spectrally efficient – voice & data on same carrier

!Protects IS-95 investment - Spectrum &infrastructure

!Superior power control features

!Delivers profitable packet data

!Supports packet data up to 307 kbps

!Low cost terminals available

Capacity, Coverage, PerformanceAdvantages Lower Costs

! 2x increase in voice capacity lowers overall cost per subscriber

! Up to 22% increase in coverage reduces cell sites required in Rural areas

! Radio Resource Management (RRM) algorithm optimizes voice and datacapacity in network

! Active / Dormant MAC states optimizes mobile battery usage and spectrum

! Quick Paging Channel Extends mobile battery life by approximately 40%over IS-95 in idle state and facilitates ‘Always On’

! Superior features enhance network performance and reduce costs

! Superior Power Control, Traffic Steering, MCTA, coherent detection

CDMA2000 1X - Increased Voice Capacity! Benefits

! CDMA2000 1X delivers up to 2x voice capacity of IS-95! 35 users per sector (EVRC): billable in mobility environment

! More users/call traffic supported in the same spectrumincreases revenue opportunity per RF infrastructure

! Description! CDMA2000 1X Standard defines the ability to increase

capacity! Fast Forward Power Control (FFPC)

! Lowers power required per user, reducing overall noise! Faster Power Control (800 Hz sampling vs 50 Hz)

! Reverse Pilot:! Power Control Synchronization - initiated by mobile

Live Network trial tests have shownactual RF power savingsenabled by CDMA2000 1X

Coverage Comparison at 800 MHz

! The Radius of a Cell is proportional to Spreading Gain

! Spreading Gain = (Spreading Rate / Data Rate)

! CDMA2000 1X Spreading Rate is constant

! Cell coverage for data dependent on data rate
