COSTA MESA, USA: The CDMA Development Group (CDG) today announced that the specifications for CDMA2000 1X Advanced have been completed and published by the 3rd Generation Partnership Project 2 (3GPP2).
1X Advanced allows 3G CDMA operators to significantly increase the voice capacity of their CDMA2000 1X network by taking advantage of several interference cancellation and radio link enhancements.
Among these improvements are base transceiver station (BTS) interference cancellation, improved power control, early frame termination, and smart blanking. 1X Advanced enhancements can be integrated all at once or in phases, offering operators an evolutionary approach to expanding existing networks based on their individual market needs. The complete set of 1X Advanced enhancements can theoretically quadruple the voice capacity of CDMA2000 1X systems in the same 1.25 MHz of spectrum.
"Both large and small CDMA2000 operators will benefit greatly from the voice capacity gains enabled by 1X Advanced," said Perry LaForge, executive director of the CDG.
"In addition to lowering the average cost per call for more affordable voice services, 1X Advanced also frees up channels to deliver 1xEV-DO broadband data services. Additionally, as operators consider augmenting their 3G CDMA networks with LTE and Mobile WiMAX, 1X Advanced will enable them to get more out of their existing circuit-switched voice networks for as long as needed."
1X Advanced builds on the CDMA2000 1X technology platform, which has been providing superior voice quality and capacity for over 10 years. Operators can now transition to 1X Advanced gradually and economically, while sustaining backward compatibility.
The spectral efficiency of the 3GPP2 standard has been recently enhanced with advanced voice codecs like Enhanced Variable Rate Codec-B (EVRC-B) and the use of quasi-linear interference cancellation (QLIC) techniques, which are already providing up to 50 percent higher voice capacity in today's networks.
The next step would be to move to 1X Advanced, which is a simple channel card upgrade (expected to be commercial in the second half of 2010) with new devices supporting mobile receive diversity, enabling them to more than double voice capacity immediately after the channel upgrade.
A complementary device enhancement known as simultaneous 1X Voice and EV-DO Data (SVDO) will also become available during the same timeframe and will enable CDMA2000 devices to access EV-DO packet data services while in an active 1X circuit-switch voice call.
For example, users will be able to send emails or access the Web while on voice calls; phones with GPS can update maps or download real-time traffic information while on voice calls, etc. This device enhancement, which enables these concurrent voice and data services, is independent of the air link standard and infrastructure.

CDMA2000 bringing 3G services to China on massive scale
BEIJING, CHINA: At the inaugural CDMA World Forum, the CDMA Development Group (CDG) commented that new 3G wireless voice and mobile broadband service offerings in China are poised to rapidly replace fixed-line solutions, exemplified by subscriber adoption of China Telecom's CDMA2000 1X and EV-DO Revision A (Rev. A) mobile broadband services.
China Telecom is now offering fixed and mobile broadband data services under its "e-surfing" brand, in addition to its existing CDMA2000(r) 1X voice and data services. The operator has already launched 3G CDMA mobile broadband services in more than 120 cities, with plans to cover 324 cities nationwide by July 2009.
By catering to its long-standing enterprise relationships, leveraging its large existing fixed-line customer base and focusing on offering mobile Internet services, China Telecom added 6.8 million CDMA2000 customers in the first four months of 2009 to reach a total of 34.71 million CDMA subscribers.
"China Telecom is showing market leadership through its commitment to bringing 3G CDMA services to China and communicating the value of CDMA2000 voice and mobile broadband services to the Chinese consumer," said Perry LaForge, executive director of the CDG. "A wide selection of affordable 3G CDMA devices is helping China Telecom realize phenomenal subscriber growth, as it leverages the CDMA2000 network to offer wireless voice and broadband data services to both new and existing customers."
Since the restructuring of China's telecom industry in 2008, the country's three wireless operators have been investing heavily in 3G networks across three technologies. China Mobile plans to invest $8.6 billion to expand its TD-SCDMA network in 2009, while China Unicom plans to put $5.6 billion into its recently-launched WCDMA network this year.
China Telecom has announced it plans to spend more than US$11.7 billion on CDMA network expansion and optimization over the next three years, while procuring 55 million CDMA2000 handsets in 2009 to support this rapid growth.
The China Ministry of Industry and Information Technology (MIIT) expects 3G wireless subscribers in the country to exceed 500 million within the next 3 years, as affordable mobile broadband services replace fixed-line Internet services and expand to rural areas.
Furthermore, an MIIT report predicts that Chinese CDMA subscribers will experience a 30.6 percent compound annual growth rate over the next four years, and that EV-DO subscribers will account for 41.1 percent of China's 3G subscriber base by 2012.
EV-DO Rev. A delivers average download speeds of 600-1400 kbps with bursts up to 3.1 Mbps and average upload speeds of 500-800 kbps with bursts up to 1.8 Mbps.
According to the China Internet Network Information Center (CNNIC), China's Internet penetration rate at the end of 2008 was at 22.6%, surpassing the global rate of 21.9 percent. China's Internet user base was at 298 million users with 279 million broadband users, while the mobile Internet user base doubled in 2008 to surpass 117 million users.
As 90 percent of all Internet users in China are also mobile users, there is enormous growth potential for EV-DO services in the mobile Internet market. This bodes well for China Telecom since its 3G network will be optimized for economical, high-speed broadband performance, and the operator will be able to offer mobile broadband data services to China's large and underserved population at attractive prices.
