LTE is a universal standard, which can be divided into two modes: FDD-LTE and TDD-LTE. China Mobile adopts TDD-LTE, which is also called TD-LTE, and most countries in the world adopt FDD-LTE system. FDD-LTE has become a 4G standard with the widest range of terminals in countries and regions in the world. There are 285 operators around the world deploying FDD 4G networks in more than 93 countries.
Swedish LTE site
On May 25th, 21, Ericsson and Swedish operator TeliaSonera launched the world's first commercial LTE(FDD-LTE) site in Stockholm, marking an important step in realizing the mobile digital highway.
as the main operator in Sweden, TeliaSonera is committed to upgrading its network, providing users with higher speed and richer services, so that users can enjoy high-speed and smooth network connection even when they are on the move. Therefore, the commercial time in Stockholm is 21. According to the agreement, the FDD-LTE system provided by Ericsson to TeliaSonera includes a new RBS6 series LTE radio base station, an evolved packet core network, and a mobile backhaul link solution including Redback SmartEdge12 router and the latest EDA multiple access aggregation switch. In addition, Ericsson is not only responsible for network management in the initial stage of network implementation and operation, but also will cooperate with TeliaSonera for a long time to promote users to use LTE mobile broadband.
TeliaSonera announced the deployment of the world's first LTE commercial site just before the global economy came out of the trough. As a part of the commercial network officially launched in 21, the launch of this site has undoubtedly provided a good model for the development of global LTE. The unveiling of this site shows that LTE is no longer out of reach, but has become a reality.
Japan's LTE license
Japan officially issued LTE licenses and plans to put them into use in 211
On May 7, 29, Japan's Ministry of Internal Affairs and Communications issued four LTE licenses. Several major mobile operators in Japan, such as NTT Docomo, Softbank Mobile, KDDI and e-Mobile, have all obtained LTE licenses without any suspense. Japan will adopt the unified LTE standard in the industry in the 4G era marked by wireless broadband, which will contribute to the rapid popularization of LTE. Based on this consideration, the Ministry of Internal Affairs and Communications of Japan has issued four LTE licenses, and the three major Japanese communication operators NTT Docomo, Softbank, KDDI and the emerging communication operator e-Mobile can get the frequency band for LTE fairly.
NTT DoCoMo, Japan's largest mobile operator, plans to invest 3-4 billion yen in the next five years to build LTE base stations and backbone communication networks. Open business next year. Softbank Mobile will invest 12 billion yen in equipment and plan to provide business in 211-212. Japan's e- Mobile company plans to invest 3 billion yen in equipment by 213, and it will start its business in 211. KDDI will provide services in 212. Its investment is more than 1 billion yen.
relevant experts pointed out that the reason why the Japanese government issued the LTE license as early as possible was to focus on leading the deployment of 4G in the world. According to the Japanese government's plan, LTE will cover 5% of Japan's population in five years.
commercial use of LTE in the United States
Verizon Wireless, a company jointly established by Verizon Communications and Vodafone, has selected Ericsson and Alcatel-Lucent as the primary network providers to support its LTE network deployment in the United States. Previously, Verizon has joined hands with Vodafone to conduct industry-leading LTE network trials in the United States and Europe. The two selected equipment manufacturers will deploy network infrastructure for Verizon Wireless, enabling it to take the lead in launching commercial FDD-LTE services in the United States from 21.
Verizon also announced that Nokia Siemens Networks and Alcatel-Lucent have been selected as the core suppliers of its IP Multimedia Subsystem (IMS) network. No matter what access technology is adopted, the system can realize rich multimedia applications. IMS will play the role of core technology in the evolution of Verizon service architecture. Verizon plans to provide IMS-based IP convergence applications and services on its wireless and fixed broadband networks. LTE will become one of the important wireless access networks adopting IMS technology. Verizon Wireless will expand its FiOS optical network while building LTE network and providing commercial services. This is a consistent and complementary development strategy, focusing on the future development of broadband market.
in fact, as early as 211, Verizon chose Qualcomm's SnapdragonMSM8655? Processor and MDM96? LTE modem chipset is also used in various new connected terminals, thus making full use of VerizonWireless' 4G LTE mobile broadband network.
Broadband service
Among the more than 1,7 authorized operators with WiMAX spectrum resources in the world, about 47 have a bandwidth of 5MHz or more, and consider using WiMAX to provide long-term profitable broadband services. Operators in the United States, Japan, South Korea, Italy, Saudi Arabia, Russian Federation, Taiwan Province and other regions have launched or plan to launch wireless broadband services based on WiMAX.
it is estimated that by the end of 29, the number of users of the top 22 WiMAX operators in the world will increase from 1.24 million to 2.5 million, and by the end of 21, the number of users will be close to 4 million. A large number of these users will come from some large proprietary network users who may switch to WiMAX in 21, such as Clearwire's network in the United States. However, among the 22 WiMAX operators surveyed by Maravedis, 42% companies are considering deploying LTE networks, which is unfavorable for the development of WiMAX.
during 29-21, WiMAX camp will face economic pressure, and many emerging mobile operators will slow down their capital investment in WiMAX, including most operators in the 3.5GHz band, who will focus on the most profitable market segment-enterprise customers looking for reliable connections. However, despite the investment difficulties, emerging markets will remain the core of WiMAX growth, and many manufacturers consider Latin America and Asia as the most attractive regions.
