The era of 3G (third-generation) wireless has arrived, thanks to technologies based on CDMA, or Code Division Multiple Access.
The CDMA Development Group (CDG), an industry consortium promoting the adoption of CDMA wireless standards, recently released a CDMA2000 deployment schedule showing that 3G rollouts continue to gain momentum. Two commercial CDMA2000 systems are already online, and the CDG expects to see additional commercial 3G systems in Australia, Japan, Latin America and North America in the second half of 2001.
Motorola is playing a leading role in CDMA's evolution to 3G. Motorola was involved in 3G launches in Brazil and Japan and is also involved in trials under way in Australia. The wireless pioneer's role in the deployment of cutting-edge CDMA networks should come as no surprise, considering recent history.
As the rollout of second-generation (2G) wireless networks picked up steam, Motorola in 1995 delivered the world's very first commercial CDMA network. The company deployed the first cdmaOne(tm) systems in Japan, China, the United States, Latin America, Africa and Israel, and, all told, has won more than 110 contracts to deploy cdmaOne systems in 24 countries.
Motorola also is the world leader in packet data wireless networks, as illustrated by its introduction of the first CDMA 64 kbps packet service during 2000 in Japan. This high-speed packet data network gives subscribers broadband access to enhanced features, including entertainment, Internet access, and more.
CDMA technology is an integral element of Motorola's Aspira(tm) total communications solutions. Motorola's Aspira has been used to deliver Internet-oriented applications such as Quick Net Connect and IS-95B High Speed Packet Data supported over 2.5G cellular systems. Motorola continues to play a leadership role in CDMA as it helps operators move to next-generation wireless Internet systems by providing enhanced access technologies and a seamless upgrade path.
Leadership Qualities
Successfully migrating to 3G requires making the right choices --about technologies, markets, and of course, solution providers. The world's leading CDMA network operators have turned to Motorola to form partnerships for a number of reasons.
Total, end-to-end communications solutions. Motorola understands that there are many dimensions to consider in launching a next-generation network. It therefore delivers seamless, fully operational 3G solutions that combine all the pieces: integrated networks, devices, applications and services, and creative commercial solutions.
The right alliances deliver the best value. The very best technology solutions most often require collaboration among expert specialists. That is why Motorola has teamed with best-of-breed companies to deliver world-class end-to-end solutions.
Together, they're helping network providers and end-users connect with information, people and devices anywhere, anytime. This ecosystem of alliances continues to grow as Motorola forms agreements with other recognized leaders to ensure the most innovative solutions come to market.
Proven leadership in advanced wireless technologies. Motorola understands the unique and complex issues faced by CDMA operators and commands leadership in the design, manufacture and sale of end-to-end CDMA wireless communications networks.
Motorola's extensive experience in delivering complete wireless data networks and services has solidified its commanding position in the industry, and it continues to build upon this expertise.
Motorola's iDEN(R) technology was the first commercially deployed high-speed packet data network and Motorola has since deployed the largest number of IS-95B packet data networks and is scheduled to have more than 20 General Packet Radio Service (GPRS) networks commercially deployed by the end of 2001. Motorola's Aspira CDMA2000 1X packet data solutions incorporate and build on these real-world experiences.
A migration path to 3G that provides investment protection. With Motorola helping to lead the way, network providers can continue to generate revenue based on their current network while moving to IP at a pace that makes sense.
Motorola's CDMA2000 1X architecture leverages existing 2G or 2.5G networks by adding packet-based network elements. Reusing equipment within the 1X architecture helps protect current infrastructure investments and ensures an orderly, cost-effective migration from 2G to 3G and beyond with minimum risk to existing revenue streams.
More migration options. Although Motorola's Aspira IP-based wireless network architecture is revolutionary in the industry, it can be achieved either by an evolutionary course or by a completely new deployment. Motorola delivers a seamless, fully operational CDMA 1X solution, which is backward-compatible with IS-95A/B.
The architecture provides a number of pathways to migrate from existing networks to IP-based networks. Each network provider determines the best route to take and how quickly to upgrade existing networks based on market requirements and growth strategies. Motorola can help network providers deploy any number of new, IP-based services, while maintaining current services and revenue streams.
The freedom to choose. While Motorola is on the leading edge of IP-based networks, the company also understands the demands placed on operators to provide and support circuit-based wireless communication solutions. As a result, Motorola continues to offer fully integrated system solutions that incorporate industry-leading switch products.
If existing switch solutions are meeting current needs, Motorola's radio subsystems can interoperate with a multitude of MSC providers via the CDMA Development Group Inter-Operability Specification (IOS).
Motorola has extensive experience ensuring interoperability between radio BSSs and MSCs for all digital technologies including iDEN, GSM, PDC and CDMA. It is the first supplier to have an international IOS system, and has already achieved commercial IOS success with Lucent and Nortel in the United States. This benefits operators wanting to take advantage of Motorola's industry leadership in BSS solutions.
Migrating to 3G
Motorola's industry-leading IS-95B 64 kbps packet data services --along with CDMA2000 1X packet data and future 1xEV-DO and 1xEV-DV wireless data solutions -- enable operators to easily and cost effectively evolve their networks so they can deliver to subscribers compelling and highly competitive wireless services, while also gaining increased revenues.
CDMA2000 1X. Through established leadership in CDMA, Motorola can deliver a quality solution that satisfies the demands for greater bandwidth and higher data rates. What's more, Motorola's CDMA2000 1X solution enables network operators to move seamlessly to 3G at a pace that matches budget realities and market demands without disrupting current operations.
Here's how:
Motorola's Aspira CDMA2000 1X solution is a fully integrated, backward-compatible solution that introduces IP transport into an existing network. It increases the voice capacity of IS-95A/B and delivers data at up to 144 kbps.
As a result, network operators can tap into the revenue-generating promise of packet-based media, which can support transactions, personalized advertising and revenue-generating Web referrals. These new services will stimulate subscriber growth and promote higher usage among existing customers. The bottom line: reduced churn and differentiation from the competition.
Motorola's CDMA2000 1X solution also enables network operators to deliver new features from third parties through Internet feature servers. These feature servers, along with Application Programming Interfaces (APIs) and the technologies of third-party developers, can rapidly deliver new experiences tailored to the unique needs and capabilities of end users.
CDMA2000 1X EV-DO (1X Evolution-Data-Only)
Motorola recently outlined its plans for supplying CDMA2000 1xEV-DO as an option in the evolution of 3G wireless systems. The CDMA standard endorsed by the International Telecommunications Union (ITU) is CDMA2000 1X; CDMA2000 1xEV-DO is phase one of the 1x evolution of this technology.
While still using the CDMA2000 1X network, operators have the option to migrate to the Motorola Aspira CDMA 1xEV-DO solution. Reusing the CDMA2000 1X equipment within the 1xEV-DO architecture will help protect operator investment and enables an orderly migration with minimal risk to existing revenue streams.
The 1xEV-DO wireless technology provides operators with up to three times more data capacity than do current CDMA2000 1X networks, and it's optimized for the bursty, high-speed, broadband access characteristics of the Internet Data Model, with a peak data rate of 2.4 Mbps. This opens the door to end-user applications barely imaginable just a few years ago.
Supported by the CDG, the 1xEV technology evolution is being developed in two standards processes. The first technology standard, called 1xEV-DO, was completed in October 2000. An approved industry schedule for phase two of the technology standard, called 1xEV-DV (1x Evolution-Data Voice) is set to be determined during the second half of 2001.
Motorola's 1X EV-DV Proposal
Motorola's standards-based proposal for 1xEV-DV allows for the delivery of next-generation, high-speed mixed data and voice applications.
In addition to supporting voice, mixed voice/data and real-time two-way services on a single carrier, it increases the peak data rate on a single 1.25 MHz carrier up to 5 Mbps with an average data throughput of 1.2 Mbps -- rates unmatched by other competing technologies. For network operators, 1xEV-DV provides the flexibility to deploy data-only carriers to maximize end-user data rates, creating an opportunity to increase revenue streams.
Motorola's 1xEV-DV proposal is backward-compatible with IS-95A/B and CDMA2000 1X, leveraging the same basic channel structures, frame sizes, and coding schemes. In fact, the same 1.25 MHz of spectrum can be used for IS-95A/B, 1X and Motorola's 1xEV-DV proposal for maximum operator flexibility. As a result, the operator's installed base of IS-95A/B and 1X mobiles is fully compatible.
Motorola is now demonstrating data applications over the 1xEV-DV air interface, a historic first step in showing the potential commercial viability of further refinements to the CDMA specifications that are expected to yield significant increases in data throughput.
The first such demonstration occurred at Cellular Telecommunications & Internet Association (CTIA) in March 2001. These demonstrations validate the air interface of 1xEV-DV, with high-speed data throughput of 3.2 Mbps over the CDMA radio-frequency channel (16 Quad Amplitude Modulation, or QAM, scheme). They also show that Motorola can increase the CDMA2000 1X data rate from its initial 144 kbps to a potential rate of almost 5 Mbps with the enhancements of Motorola's CDMA 1xEV-DV air interface.
Motorola 's CDMA2000 1X, 1xEV-DO and 1xEV-DV are key elements of the Motorola Aspira total communications solution. The Aspira solution delivers on technology's promise, through Motorola's partnerships with other leading companies, to develop a full range of IP and packet-based solutions for voice, multimedia and data networks.
These solutions will empower network operators and service providers to bring wireless Internet services, voice-over-IP and feature-rich global mobile services to the world.
Advantages for Next-Generation CDMA Operators
Fast and flexible deployment. An orderly, clear path forward. Outstanding cost efficiencies. Superior end-user experiences. These are among the most important needs expressed by today's wireless operators and service providers as they move forward to 3G services. Motorola's wireless solutions have been designed to deliver the key ingredients that will enable success in 3G.
Orderly migration for existing operators and rapid deployment for new operators. Motorola's 3G solutions offer telecom operators an orderly migration path as they transition from today's switch-based, hierarchical systems to IP-based, client-server networks. Operators with existing legacy investments gain the additional benefit of full interoperability with existing Radio Access Network (RAN) infrastructure.
For example, Motorola's IP RAN solutions build upon the existing Base Station System (BSS) architecture by adding key components, enabling packet-data transport. This helps network operators protect their current investment and provides a smooth migration path to implement the CDMA200 1X functionality through software and incremental hardware upgrades.
Rapid delivery of services. A distributed client/server approach, coupled with an open-API philosophy, means operators can more rapidly introduce new IP-based services. Operators are able to build competitive differentiation and enhance end-user relationships by being first to market and engaging customers with the newest voice, data and multimedia services. For example, simple cost-effective board and software upgrades result in faster time-to-market and cost savings.
Reduced cost of ownership. Motorola's packet-based IP approach can lower the total cost of network ownership. Operators will enjoy optimized bandwidth efficiency, reduced network management costs and easy, incremental system scaling.
For example, the Motorola CDMA2000 1X BTS (Base Transceiver Subsystem) supports 2G, 2.5G, and 3G standards so network operators can follow a cost-effective, scalable transition path -- at their own pace.
Superior end-user experience. Motorola's IP-based approach permits the development and delivery of feature-rich, customized and personalized end-user services and applications that are easy-to-use, ubiquitous and available with speedy access.
