Major Enhancements incdma2000 1x Revision D

• Support of 1x EV-DV Reverse Packet Channel– Mobile station is required to support 1.23 Mbps; 1.53 and 1.84 Mbps are

optional– Shorter frames– Higher capacity

• QoS-related features– Support for multiple flows per user, and enhancements for QoS

• BCMCS (Broadcast and Multicast Service)• Changes specific to Layer 3

– Faster call setup• Direct Channel Assignment• Reduced SCI Operation• Traffic Channel Initialization Enhancements• Tracking zone reporting• Radio environment reporting

– Support for MEIDs (mobile equipment IDs, ESN replacement)– PLCM Enhancements– SYNC_ID enhancements – Multiple Services Enhancements
