-MONMITA JENA OBJECTIVES Introduction to 1xEVDO
Evolution Stages
EV-D0 – the talk of the town
Architecture
Comparison
Advantages
Future Enhancements
Combating Rivals
Slide 3:Evolution Data Optimized
Wireless Data Transmission
 It is standardized by 3GPP2
Evolution of CDMA2000(1XRTT)
An EV-DO channel has a bandwidth of 1.25 Mhz
The back-end network is entirely packet-based
Standard Revisions:
Rev 0
Rev A
Rev B 1XEV-DO

Slide 5:In VoGue..Why? Always on with seamless roaming
Provides crystal-clear video on demand, live-action 3D games, news, sports, music videos, and much more
Backward compatibility
Compatible with almost all OS supporting IP
Uses Adaptive Modulation
Offers bandwidth efficiency for data traffic that is 3-4 times greater than other voice-centric standards
Same range as a cell phone signal.
It provides mobile devices (handsets and wireless modem air cards) :It provides mobile devices (handsets and wireless modem air cards)
Slide 7:Architecture • Radio Nodes (RNs)
• Radio Network Controller (RNC)
• Packet Data Serving Node (PDSN)
Slide 8:Comparison
Slide 9:Service Providers Qualcomm: granted Airvana a license under certain Qualcomm CDMA patents to develop, manufacture and sell 3G CDMA2000 1xEV-DO.
Verizon
Sprint
ACL- Coverage in Malawi.
ACS - Coverage in Alaska, USA.
Alegro PCS- Coverage in Ecuador.
Alltel- coverage in the United States..
Bakrie Telecom- Coverage in Indonesia.
Bayn- Coverage in Morocco.
BSNL - Coverage in India.
Slide 10:Business Sense In 5Mhz spectrum
1xEVDO delivers 3.2Mbps
CDMA20001x & WCDMA delivers 1.1Mbps
GPRS 80Kbps
Cost to deliver 1MB:
1xEVDO = $0.02
CDMA20001X & WCDMA = $0.07
GPRS= $0.042
A perfect case for better networks, applications, and mobile access devices to support high volumes of data at higher throughput.
Slide 11:Advantages Superior fault tolerance
Scalability
Efficient Multiplexing
It utilizes data only and segregates itself from voice traffic.
Flexible low cost, IP transport
With only minor modifications required at CDMA-based cell sites to install
EvDO may make Internet cafes a thing of the past because it works everywhere a cell phone works.
Future EV-DO: REV B :Future EV-DO: REV B Enhanced Experience for Broadband Apps Increased VOIP performance
