1xEV-DO IS-856 Rel. 0 & Rev. A 1x & 1xEV-DO
• The IS-856 Enhancements achieved with 1xEV-DO Release 0
• IS-856 Enhancements are compatible with Revision A
• Enhancements are software upgrades (e.g. Video Conferencing, QoS, gold multicast, and LBS)
• Receive Diversity: Incremental HW upgrade - either on the BTS or the mobile, or both
• Equalizer requires HW changes on mobile.

QoS: Ability to Offer Tiered Services to UsersQoS: Ability to Offer Tiered Services to Users
•Inter-user QoS (differentiate users):• Enables system to treat various users with different levels of priority• Tiered pricing plans for different classes of users (Gold, Silver, Bronze)• On a per session basis, check user’s profile in AAA server and match it to a level of
service• Assign priority level to the scheduler and RL MAC for the user• No device impact

QoS: Support Apps With Various Delay Requirements QoS: Support Apps With Various Delay Requirements
•Intra-user QoS (differentiate applications):• Applications can be treated with different priority based on the delay requirements• Delay sensitive traffic can have higher priority• Optimal user experience for various types of applications• Applicable to one user’s traffic as well as across all users

•1xEV-DO Gold Multicast• Multiple channels of content can be distributed to many users at the same time (One to
Many)• Capacity efficient method to distribute content in a cellular environment• Users may choose various content based on pricing plans

Higher Capacity with 1xEV-DO EqualizerHigher Capacity with 1xEV-DO Equalizer
• 1xEV-DO Equalizer Results in 20-30% Capacity Improvement in Low Mobility Environments:
• Higher data rates achievable in a larger percentage of the cell area• Gains more predominant in low mobility environments, where device uses the
equalizer to compensate for multipath and reduces interference• Does not change the 1xEV-DO standard or existing infrastructure• Both single and dual receive devices can take advantage of equalizer and
realize higher gains• Devices will use both the RAKE and Equalizer receivers

Receive Diversity: Competitive Advantage for CDMA2000Receive Diversity: Competitive Advantage for CDMA2000
• Receive Diversity (Rx Diversity) Benefits Voice and Data Services:• Devices with 2 receive chains and 2 antennas • Base stations with 4 branch receive diversity
• Increasing Capacity with Receive Diversity:• Does not require a new standard• Is completely transparent to the operation of the
network and users• Can be rolled out as needed over time• Forward link: SMV-1 + Rx Diversity Increase Sector Capacity
from 23 to 52 Erlangs• Rev. Link: SMV-1 + 4 Branch Diversity Increase Sector Capacity
from 23 to 52 Erlangs• Maximum Supportable Path Loss Improved by 5-6 dB:• Battery life increased, since handsets use less power within existing network plans
• Same Handset Form Factors Achievable:• Higher component integration through ZIF architecture

•Location Based Services over 1xEV-DO• Rich multimedia content coupled with location based services• 1xEV-DO fast downloads enable location relevant information with an improved user
experience• Location information acquired over 1xEV-DO airlink along with the rich content

Page 21 February, 2004 QUALCOMM PROPRIETARY
1xEV-DO Evolution: Key Physical Layer Features of Revision A1xEV-DO Evolution: Key Physical Layer Features of Revision A
Forward Link:• Supports a wider range of physical-layer packet types
• Smaller payloads for improved packing efficiency • Larger payloads to support higher data rates (up to 3.1 Mbps)
• Packet-division Multiplexing• A single physical-layer packet contains one or more upper-layer packets
addressed to different users
Reverse Link:• Flexible packet length and structures
• Improved packing efficiency
• Finer rate quantization and Higher peak rates• Support data rates up to 1.8 Mbps
• Supports physical-layer hybrid ARQ• Performance gain from similar concepts as FL ARQ today

2X Multi-Carrier2X Multi-Carrier
•Simultaneous Voice and DO (SVDO)• Simultaneous voice (1x) and high speed
data (1xEV-DO) in the same device• One device accesses both airlinks at the
same time.• Eliminates load balancing issues that
may arise from mixing voice and high speed data services within a single frequency carrier
•Double DO (DDO)• In the future possible to have devices
with ability to access two 1xEV-DO carriers simultaneously
• Doubles the 1xEV-DO data rates for a given user (2 * 2.457 Mbps ~ 5 Mbps)

SummarySummary
• 1xEV-DO Today Offers Services and Performance Unmatched by any Commercial Technology
• As part of CDMA2000 family, it serves packet data services with highest performance, and lowest cost
• Proven, commercial networks, devices, and services are available today• Operators can churn away customers from the competition
• 1xEV-DO has a Very Strong Migration Path Going Forward• Valued Added services possible with software upgrades to 1xEV-DO deployed
systems• These differentiating services can offer even more revenue opportunity for operators,
and attract customers away from the competition• Furthermore, there is a clear roadmap of enhancements for higher capacity, higher
level of integration, and a wide range of devices with various price and performance points
• CDMA2000 Operators are in a Very Good Competitive Position, as they Roll-Out 1xEV-DO in the Near Term, and have the Capability to Evolve the Networks and Devices Going Forward
