CDMA ROADMAP OFFERS ENHANCEMENTS TO CDMA2000 1X AND EV-DO AND A PATH TO OFDM-BASED TECHNOLOGIES

The CDG Outlines the Long-Term Technology Options for CDMA Operators at its CDMA2000/LTE Workshop During CTIA Wireless 2009

LAS VEGAS — April 01, 2009 — The CDMA Development Group (CDG) is holding a workshop today at the CTIA Wireless 2009 conference that will outline the long-term CDMA2000® technology roadmap, which includes enhancements to CDMA2000 1X and 1xEV-DO technologies as well as LTE and Mobile WiMAX. CDMA operators can extend the value of their current investments with the enhanced CDMA2000 roadmap, which increases 1X voice capacity and EV-DO performance by leveraging existing devices and network assets. The roadmap also provides for seamless interoperability of wider-bandwidth OFDM-based technologies with CDMA2000, enabling CDMA operators to implement LTE and Mobile WiMAX in their networks.

“CDMA2000 is a flexible solution that continues to be enhanced, building on its industry-leading performance for voice telephony and mobile broadband while positioning CDMA operators to succeed with complementary OFDM-based technologies,” said Perry LaForge, executive director of the CDG. “In today’s economic environment, the CDMA2000 roadmap offers operators an opportunity to retain their competitive advantages without having to make substantial capital investments. Further, if an operator intends to deploy LTE or Mobile WiMAX, the CDMA2000 roadmap offers them a direct integration path to deliver additional mobile broadband capacity and performance."

At the CDG’s CDMA2000/LTE Workshop, leading vendors and infrastructure providers will provide insight into the evolutionary enhancements coming to CDMA2000 1X voice and EV-DO mobile broadband technologies. The session will also cover the factors driving LTE adoption, provide perspectives on LTE for CDMA2000 operators and outline the path for interoperability between CDMA2000 and LTE. The workshop will describe several long-term network strategies, which will range from an enhanced CDMA2000-only network strategy, a hybrid strategy with CDMA2000 augmented by interoperability with LTE, or a longer-term strategy towards LTE.

The workshop will highlight CDMA2000 1X enhancements that increase voice capacity up to four times that of today’s CDMA2000 1X networks, a natural step for operators looking to lower their cost per call and free up channels that can be used for EV-DO broadband data services. Workshop attendees will also hear about multi-carrier EV-DO software upgrades that will significantly increase the network capacity and user experience of existing EV-DO Revision A (Rev. A) networks. The workshop will also detail additional EV-DO enhancements based on software upgrades and MIMO technology that will extend the long-term value and performance of EV-DO. These enhancements will increase EV-DO data rates up to 32 Mbps in the downlink and up to 12.4 Mbps in the uplink within 5 MHz of spectrum, while supporting VoIP and concurrent voice and data services to supplement existing 1X circuit-switched voice services.

“CDMA2000 operators will be among the first to integrate OFDM technologies like LTE and Mobile WiMAX with their existing 3G networks, building on the successful business models they’ve developed for mobile broadband with EV-DO,” continued LaForge. “OFDM-based technologies have become a desired component of the CDMA2000 roadmap, along with the enhancements to 1X and EV-DO which we believe many CDMA operators will continue to use as viable long-term solutions for voice and mobile broadband services.”

The CDMA Development Group’s CDMA2000/LTE Workshop will be held on April 1, 2009 from 2:30-5:00pm PDT in Room N254 at the CTIA Wireless 2009 conference in Las Vegas. The workshop is free to all registered CTIA conference attendees, but due to limited room capacity registration is required at http://www.cdg.org/news/events/CDMASeminar/09CTIA-workshop/index.asp.
