According to the latest data from GSA, there are currently 244 LTE commercial networks in the world, an increase of 78% compared with last year. Undoubtedly, all members of the industry are expecting the early commercialization of China's 4G network; China Mobile said that its first 4G LTE mobile phone sales are very hot. Yes, consumers can't wait.
On December 18th, China Mobile Global Partner Conference was held in Guangzhou. The conference attracted more than 5,000 industry representatives. There is no doubt that everyone's eyes are attracted to 4G. Looking forward to 2014, the Chinese market and integration win-win will become the global 4G development keywords.
The top priority in the Chinese market: covering a wide range of needs
China Mobile announced at the partner conference that in 2014, China Mobile's TD-LTE (LTE-TDD) terminal sales target is 100 million units. It is worth noting that during the conference, many mobile phone manufacturers released or displayed 4G LTE terminals, including Sony Xperia Z1 4G mobile version, Samsung Galaxy Note 3, Nubian Z5S LTE mobile version, vivo Xplay 3S, Tianyu Touch 3, Huawei G716. LTE, HTC One max, Hisense X6T, etc., from the high-end to the entry-level, are readily available. When the 4G license was issued, the terminal industry chain quickly matured and it was very exciting.
For a time, has China been an “emerging†or “developed†market? Different people always have different interpretations. However, there is no doubt that China has the largest and most complex consumer group, which means that manufacturers need a processor platform to support all user needs and thus “cover all consumersâ€, which is a top priority for the Chinese market.
The thinking of mobile phone manufacturers coincides with Qualcomm, and Qualcomm is actively practicing "using a platform to meet all needs." For example, Qualcomm has announced that it will expand 4G LTE into all of Snapdragon's product lines. OEMs can use Snapdragon processors to develop intelligent terminals that cover the market's complete needs, thereby reducing R&D costs.
For example, Sony Xperia Z1, Samsung Galaxy Note 3 and other global flagship LTE mobile phones mostly use Snapdragon 800 processor, and this processor is also actively adopted by domestic manufacturers, Nubian Z5S, Lenovo VIBE Z, Gionee ELIFE E7 , vivo Xplay3S, etc. will launch LTE version, built-in Snapdragon 800 processor; and in the massive market, a large number of intelligent new machines with built-in Snapdragon 400 processor released, Qualcomm and smartphone manufacturers promised that "will be originally high-end intelligence The performance of the machine is shifted to the mass market, and they are fulfilling this promise. For example, the global hot-selling Moto G, the Hisense X6T and the Tianyu Touch 3 released in China all support multi-mode multi-frequency, and both are aimed at the mass smartphone. market.
About the massive market, Qualcomm's new Opteron 410 series processor is very eye-catching. This processor is designed for the thousand-yuan LTE smartphone market. It is manufactured with 28nm process technology, supports 64-bit and integrates Adreno 306 GPU, supports 1080p. Video playback and up to 13 megapixel camera. The Snapdragon 410 chipset integrates 4G LTE and 3G cellular network connectivity to all major modes and bands worldwide, supporting dual SIM and triple SIM cards, supporting all major satellite navigation systems, including GPS and GLONASS. ) and the Beidou system. In addition, the processor's Qualcomm Reference Design (QRD) version will also be available.
Fusion to achieve a win-win situation
As we all know, the LTE standard is the crystallization of the common wisdom of the world. No country or enterprise can claim to have a decisive influence on 4G. Therefore, “fusion†has become another key word for the development of LTE in 2014. According to the Ministry of Industry and Information Technology, the integration and common development of TD-LTE (LTE TDD) and LTE FDD has become the trend of the global mobile communication industry in the future. Li Yue, president of China Mobile, said that because of the spectrum, there are two branches of TDD and FDD in 4G technology. He believes that the integration of TDD and FDD will not only make the greatest contribution to China Mobile, but also to the entire industry. Li Yue said at the China Mobile Global Partner Conference that “the same mobile phone has more 4G per mobile phone. Mode, 10 frequency, 12 frequency, 14 frequency, the same use, the same business can be used on all mobile phones." Regarding convergence, Li Zhengmao, vice president of China Mobile, also said recently that China Mobile will work closely with global operators, industry partners and international organizations to create a high-performance, low-cost, globally unified 4G broadband network that will ultimately achieve Hand, travel all over the world." In China Telecom, Wei Leping, director of the China Telecom Science and Technology Commission, said in an interview with the media recently that in the 4G network planning, China Telecom will adopt the TDD and FDD hybrid networking mode and gradually implement the integrated networking. Wei Leping said that FDD and TDD are two different access modes under the unified LTE standard. The LTE standard is the crystallization of the common wisdom of the whole world. Combined with the national conditions and coordinated development, it will be the most favorable strategy for LTE development.
From the above statement, "fusion" consists of two levels. First, FDD and TDD are common. LTE is a global standard based on the technical specifications promulgated by 3GPP. The uplink uses single-carrier FDMA, and the downlink uses OFDMA, and is applicable to the deployment of paired and unpaired spectrum. The LTE standard supports two duplex modes, FDD for paired spectrum and TDD for unpaired spectrum. Based on the experience of managing 3G networks, in order to avoid market fragmentation, leading global operators have promoted LTE as a general standard to support FDD and TDD modes from the beginning. There are only very small necessary differences between the two modes, and the two modes are shared between the two modes. The similarity is over 90%. Li Yue, president of China Mobile, believes that the current 4G industry has realized "using the same chip, the same mobile phone, the same business can be used on all mobile phones, achieving complete integration of TDD and FDD. No matter technically, in terms of performance, In terms of price, or from the development of convergence, today's TDD and FDD are exactly the same. "Convergence will bring prosperity," said Alan Hadden, chairman of the Global Mobile Equipment Suppliers Association (GSA). "Because LTE is a global unified, universal standard. LTE FDD and TDD network deployment and user terminal manufacturing can greatly benefit from the global scale economy of LTE. In addition, thanks to the universal standard of LTE, Chinese mobile phone manufacturers can no longer be different from the technical standards of domestic and foreign markets. Restricted, quickly and seamlessly enter the international market, standing on the same starting line with internationally renowned manufacturers.
Second, LTE will coexist with 3G for a long time. China Mobile’s statement that “one machine is in hand and travels all over the world†is a good example of this. And Wei Leping also said that after the 4G, with the changes in user habits and the development of applications, it will stimulate a large increase in traffic, and 3G also faces the problem of expansion. In the next two to three years, China Telecom will focus its resources on stepping up the construction of 4G networks, and will also make limited necessary expansion of 3G networks.
Observing the form of 4G mobile phones at home and abroad, multi-mode multi-frequency is almost a must. According to statistics, more than 99% of the currently released LTE handsets support 3G/LTE multimode.
The road to the future: the industry is concerned about the continued evolution of LTE
LTE is rapidly expanding, and industry leaders have taken the lead to focus on the next generation of LTE technology, LTE Advanced. LTE Advanced includes a variety of enhancement technologies, which can be divided into the following three categories: carrier aggregation technology that can utilize more spectrum, advanced antenna technology that improves spectrum efficiency, and make full use of heterogeneous networks of small base stations.
At present, most people in the industry believe that carrier aggregation will be an important technology for operators to use all available spectrum. As we all know, operators will get spectrum of different bandwidths and different frequency bands. Carrier aggregation is the bonding of all of these together. At the same time, the basic feature of the LTE Advanced standard is carrier aggregation.
At the MWC at the beginning of this year, Qualcomm took the lead in demonstrating the next-generation mobile connectivity using LTE Advanced carrier aggregation technology. A few months later, the Samsung Galaxy S4 LTE-A with the built-in Opteron 800 processor was the first to commercialize the technology. Recently, ZTE released softbank mobile SoftBank 203Z and eAccess GL09P mobile router based on Qualcomm processor, adopting carrier aggregation technology, and the downlink transmission rate can reach 110Mbps.
It is worth noting that Qualcomm is one step ahead. It announced the release of its 4th generation 3G/LTE multimode modem and RF transceiver chip. Qualcomm Gobi 9x35 is the first 20nm nanotechnology-based cellular modem to support LTE TDD and FDD Category. 6 Global carrier aggregation deployment of up to 40MHz on the network, the download rate can be up to 300Mbps. The Snapdragon 805 processor, which was also released at the same time, will also partially integrate the modem.
