Elements of Deployment Strategy
One to One overlay of GSM Network in Areas where UMTS/HSDPA isimplemented
Initially at 1900MHz, Some Markets at 850MHz from 2006 Depending on Available Spectrum
Dual-band 1900/850 Devices from Day one
UMTS/HSDPA first deployed in Metropolitan Areas GSM/EDGE used for Service Continuity
GSM to UMTS and UMTS to GSM Handover / Cell Reselection GSM used for E-911 Ph.2 compliance (Emergency Calls Re-directed to
GSM) Maximum Site Resource Sharing across Technologies
Antennas, Feeders, Transport, Power, E-911 Common Core Network Elements beyond MSC/SGSN HLR, GGSN, Billing System, Service Platforms

Device Strategy
Multi-mode, Quad-band GSM/EDGE, Dual-band UMTS/HSPA GSM/EDGE Multi-slot Class 12 HSDPA Devices:
Category 12 initially (1.8Mbps) Category 6 now (3.6 Mbps)
Category 8 soon (7.2 Mbps) Advanced Receivers required to achieve High Peak Data Rate
Equalizer or Rx/Div available now Rx Div + Equalizer to be available by the end of 07
Bluetooth, Java, Browser, Camera, WiFi now A-GPS, MediaFLO soon
Subset of UMTS/HSDPA Devices available on AT&T web site as of 7/7/25

Service Strategy
Voice / Data / simultaneous Voice + Data Superior Voice Quality through CS Voice using AMR12.2
(Default UMTS Codec) Lower AMR Rates being deployed for improved capacity VoIP and/or MMTel (MultimediaTelephony) not needed but under
consideration Best effort/Interactive/Background Data Bearers
Streaming class soon (Streaming can also be carried over I/B) Conversational with VoIP/MMTel later on
Music/Video Download
IMS-based Video Share Broadcast with MediaFLO

Lessons Learned
UMTS/HSDPA Standard is extremely Flexible Infinite amount of possible combinations of Voice & Data Bearer
Combinations requiring Intense Inter-Operability Testing Large set of Features & Capabilities
But less of a problem for new operators Inter-RAT (Radio Access Technology) Operation may be tricky
GSM-UMTS Inter-system Handover may be used to move Devicesacross Technologies when encountering marginal propagation conditions(especially when operating UMTS@1900 and GSM@850)
Inter-RAT Threshold setting becomes a key Network Optimizationcomponent
Transport Dimensioning is an essential part of achieving High
Throughput Performances Soon, the Performances will not be limited by the Devices and Network
capabilities but by the Transport Dimensioning
