Qualcomm Demonstrates Enhancements for CDMA2000 1xEV-DO at CTIA
Wireless 2003
March 18, 2003
Qualcomm today demonstrated a suite of new enhancements for CDMA2000
1xEV-DO, a 3G wireless technology optimized for data, at CTIA Wireless
2003 in New Orleans. In line with the Company's vision of technology
innovation, these advanced enhancements will provide time to market
advantage and will further build on the momentum of CDMA2000 1xEV-DO
deployments worldwide.
The enhancements shown in live demonstrations today continue the
natural evolution of CDMA2000 1xEV-DO by providing the capability
for richer multimedia experiences, faster data rates and higher
system capacity for network operators. These capabilities will benefit
enterprises and mobile consumers, as well as fixed residential users
of CDMA2000 1xEV-DO service.
"Qualcomm is continuously looking for ways to improve and advance
CDMA's capabilities, and in the case of CDMA2000 1xEV-DO, the addition
of new and differentiating features will provide subscribers an
even greater wireless experience," said Dr. Roberto Padovani, chief
technology officer, Qualcomm. "The enhanced features also enable
new revenue streams for operators. Operators across the globe can
benefit from a suite of leading edge features, while minimizing
system upgrade costs."
The CDMA2000 1xEV-DO enhancements demonstrated at CTIA in Qualcomm's
booth are currently in various stages of implementation and standardization.
These key feature enhancements include:
- Quality of Service (QoS): The Quality of Service (QoS) feature
enables the system to treat various users and applications with
different levels of priority. The system has the ability to recognize
traffic with higher priority and send those packets ahead of others.
Operators can thereby offer tiered services and multiple pricing
plans for different user classes.
- Instant Multi-Media (IMM): The Instant Multi-Media (IMM) concept
can be used to implement conferencing with the additional capability
to send video images to the entire group. The IMM concept is unique
in that both audio and video can come from the same user or from
two different users.
- Location Based Services (LBS): When in need of Location Based
Services (LBS), CDMA2000 1xEV-DO can quickly download an array of
multimedia images that are relevant to the specific location of
the user in the wide area network.
- Equalizer: Advanced signal processing in user devices enables
the Equalizer feature to significantly increase user data rates
and capacity in a given CDMA2000 1xEV-DO network. The Equalizer
enables devices to provide faster Internet access, quicker downloads
and broader applications usage.
- Receive Diversity: Receive Diversity uses additional antennas
and associated receive chains to enable a device or network to have
improved signal reception. Building on Receive Diversity techniques
pioneered by CDMA2000 1xEV-DO, the improved signal reception translates
into higher data rates for CDMA2000 systems. The receive diversity
techniques can also be utilized to provide an additional doubling
of CDMA2000 voice capacity.
- 2X Multicarrier: The initial capability demonstration of 2X Multicarrier
shows the possibility in the future of having devices with the ability
to access two CDMA2000 1xEV-DO RF carriers simultaneously, thereby
doubling the available data rates. The peak data rate on the forward
link can in effect be up to 5 Mbps. In addition, simultaneous voice
and high-speed data are possible in the future with devices able
to access both CDMA2000 1X and CDMA2000 1xEV-DO at the same time.
