What is QoS and Why is it Important?Enables different types of traffic to share the resources

Prioritize by packet TYPE

Each Packet gets exactly what it needs, when it needs it.

AS Application Signaling

DS Delay Sensitive

RS Rate Sensitive

BE Best Effort

Applications can be treated with different priority based on their QoS constraints

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

Multi-Link PPP (MLPPP)4.0

Reduces # of Abis T1s/E1s Up to four links are pooled Provides trunking efficiency and,

therefore, higher throughput

Increased Reliability Link failure does not cause

disruption to service Router can react faster to failed

link compared to presentsituation where RNC is requiredto detect the failure

Simplifies Implementation Balances load over links

Widely supported feature inrouters

IP Planning simplified to one /30

Reduces the differential delay Reduces out-of-order packets

Rel 4.0 BTS / DOM-A FeaturesFractional T1/E1 Support

Rel 4.0 Fractional T1/E1 Configuration

Existing Configuration

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

> More QoS flows (up to 7) to support different type of applications Specifically target for VoIP and Push-to-Talk (PTT). Separation of VoIP and PTT flows = More optimal performance & capacity

for each.

> Dynamic allocation of QoS resources = Ability to support moreusers with better resource utilization.

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

Mix of chassis with Existing Modules and chassis with High Capacity modules

Benefits of RNC Cluster w/ full mesh architecture: Lower cost of ownership

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..!!!

Case 2: With RNC Clustering

Growth in traffic demand in particular areas can/will be absorbed or shared

across a larger resource pool within the cluster.

Thus, still NO RNC borders, and NO need for optimization.Superior Network Performance by nature

Reducing both CapEx and OpEx.

Advertised Average Peak Rates

Typical download speeds average 6001400 kbpsbased on our network tests with 5 MB FTP data files,without compression. Typical upload speeds average

500800 kbps. Actual speeds and coverage may vary. Ifusage exceeds 5 GB/line/month, we reserve the right to

reduce throughput speeds to a maximum ofapproximately 200 Kbps.

With the evolution to EV-DO Revision A, users in

markets where it is rolled out, will experience fasteraverage download speeds of 600 kbps - 1.4 Mbps andaverage upload speeds of 350 -500 kbps.
