Prioritize by packet TYPE
Each Packet gets exactly what it needs, when it needs it.

Faster Sector Switching
Rev 0: DRC alone indicates ATs intent to switch cells
AT waits on new sector for data transition
DSC Channel indicates ATs intent to switch cells
Data Source Control (DSC) channel allows the AT to send its cellselection independent of the DRC
AN begins the transition to the new cell while the AT continues to use its DRC toreceive data from the current cell
Minimizes inter-cell handoff time and reduces overall latency

Pre-release 4.0 typically requires 3 T1s (2 full T1s for the DOM traffic and 1 fractional T1 for DCG for OAM traffic)
In Release 4.0, Fractional T1/E1 Support allows DOM to interface to a fractional T1/E1Fractional T1/E1 support can eliminate 1 T1/E1 by utilizing existing daisy chain capability of the BTS

R5.0: Better Spectral EfficiencyEnhanced Multi-flow Packet Application (EMFPA)
> With EMFPA, Nortel 1xEV-DO R5.0 will substantially reduce theoverhead message for packet voice
Via the use of packet-based RLP, instead of PPP/HDLC.
And Robust Header Compression (RoHC), which providecompression on the IP, UDP and RTP headers.
> For instance, a voice header of 40 bytes can be reduced to justabout 2 bytes.
Together with 22 bytes of VoIP audio data, the total of 24 bytes cannow be carried in a single reverse link 1xEV-DO Rev A subframe.
Higher Spectral Efficiency with EMFPA means More Capacity for VoIP users Less delay for voice applications

Clustering: Seamless Network GrowthPre-Cluster adds are expensive, time-consuming
Growth in a particular RNC drivesthe demand to re-distribute the
traffic load to other neighboringRNCs.
Re-distribute = Rehome DOM to
neighboring RNCs = New RNCborders
New borders = another round of inter-RNC optimization..!(est. of more than $119k per Rehome) & Customer Service Interruption..!!!
