On December 4, the Ministry of Industry and Information Technology issued 4G licenses, and China's 4G LTE development ushered in accelerated development. According to the picture outlined in the "Broadband China" Strategy and Implementation Plan, the total number of 3G / LTE users in China in 2020 will reach "1.2 billion", which is almost equivalent to the total population of Europe and North America. The industry generally believes that in the "time window" of 2014, China's LTE users will show explosive growth.
Time: Uniform standards bring common prosperity
4G LTE is one of the fastest-growing technologies for mobile communications in the history of users. From the first commercial deployment, it has reached 100 million connections in only three and a half years. According to GSA data, there are currently more than 144 million LTE / 3G multimode connections in the world, and 222 commercial LTE networks have been deployed in 83 countries.
On the one hand, the rapid popularization of 4G LTE has benefited from the explosive development of mobile Internet and smart phones. On a deeper level, LTE, as a universal standard, is particularly helpful for the global construction of a unified industrial chain. Various communication standards are incompatible with each other in the 3G era. This problem does not exist in the 4G era. LTE is a global standard based on the technical specifications issued by 3GPP. Single carrier FDMA is used for uplink and OFDMA is used for downlink. Deployment. Based on the experience of managing 3G networks, in order to avoid market fragmentation, global operators have promoted LTE as a universal standard from the beginning to support FDD and TDD modes. There are only very small necessary differences between the two modes.
At present, it seems that because LTE FDD is deployed earlier in the world, it has already achieved the maturity and success of the terminal scale. The LTE TDD terminal was launched late, but due to the commonality of technology and products, TDD will benefit from the scale of FDD deployment. At present, 11 of the 23 LTE TDD commercial networks in the world are launched by operators who have deployed LTE FDD networks, and more than one hundred terminals support both LTE FDD and TDD to meet the operators ’own network needs and users’ global roaming needs . Mr. Alan Hadden, Chairman of the Global Mobile Equipment Suppliers Association (GSA) believes, "Because LTE is a globally unified and universal standard, network deployment and user terminal manufacturing of LTE FDD and TDD can greatly benefit from the global economies of scale of LTE.
The Ministry of Industry and Information Technology said that the integration and common development of TD-LTE and LTE FDD have become the future trend of the global mobile communications industry. At present, China has planned TDD and FDD radio frequencies. In order to make full use of frequency resources and facilitate users to use mobile communications services at home and abroad, China needs to develop TD-LTE and LTE FDD as a whole.
If we believe that the arrival of the "development opportunity period" requires multiple factors of "time, geographical location, harmony". Then the "uniform standard" is "day and time".
Location: All parties in the industry are ready
Regarding "geographical advantages", the active promotion of 4G LTE by Chinese authorities and operators has attracted worldwide attention. At present, China Mobile and others have built LTE test networks in various places. It is understood that China Mobile has built 20,000 base stations in 15 cities last year. China Mobile Chairman Xi Guohua proposed the "Double Hundred" target this year, and LTE TDD will be covered by the end of this year In more than 100 cities, 200,000 base stations are being built, and the purchase volume of LTE terminals exceeds 1 million. Gong Bin, Managing Director of Bosi Consulting International Co., Ltd. believes that from the perspective of user development and revenue, 4G development is much faster than the initial record of 3G network deployment. In the next three years, the domestic 4G market will show explosive growth rather than The initial incremental growth of 3G.
From a global and industry-wide perspective, large global operators have jointly launched 222 LTE networks and 1000 with leading global chip suppliers, equipment manufacturers, and mobile phone manufacturers such as Qualcomm, Huawei, ZTE, Ericsson, Sony, Samsung, etc. The remaining LTE terminal equipment. The most noteworthy thing is that in the 2G era a few years ago, it was difficult for domestic mobile phone companies to make achievements in the high-end field; 3G / LTE is "a big difference." Tianyu has released many LTE mobile phones and data cards in China and overseas. For example, Lenovo VIBE Z, Gionee ELIFE E7, nubia Z5S LTE, Tianyu Bumblebee 4G, etc. have all adopted the Snapdragon processor. 3G multimode connection; in October this year, Japanese operator Softbank released ZTE 203Z and eAccess GL09P mobile routers, supporting LTE carrier aggregation / WCDMA multimode, with a maximum download speed of 110Mbps, which is the world ’s first batch based on Qualcomm ’s third generation Commercial terminal for LTE modem MDM9x25.
Renhe: User experience greatly improved
The Ministry of Industry and Information Technology said that in the future, 2G, 3G and 4G networks across the country will coexist for a long time. Therefore, to achieve seamless interoperability between LTE and 3G and 2G through multi-mode 3G / LTE terminals is the basis for LTE to provide users with an excellent experience and the key to LTE's success. In densely populated urban areas, the demand for data services will be quite large. In these areas, LTE can significantly increase data capacity and effectively enhance 3G networks. 3G and its evolution technology will continue to provide ubiquitous broadband services, similar user experience and voice services outside the LTE coverage area.
Observing the shape of 4G mobile phones at home and abroad, multi-mode multi-frequency is almost a must. According to statistics, over 99% of the LTE mobile phones released so far support 3G / LTE multi-mode.
In addition, 4G LTE will drive the upgrading of mobile terminals and promote more and better applications. For consumers, they still crave terminals that are sleek, light, powerful, always online, and have a long battery life. Terminal manufacturers are concerned about whether they can use the same chip platform to launch a 4G product series that meets the needs of the complete market from entry-level to mid- to high-end. At present, Qualcomm maintains a leading position in 4G LTE and 3G chip solutions and technologies. Its third-generation LTE chipset has been commercialized on a large scale, and it is also the first company to launch an LTE-A chipset that supports carrier aggregation. All LTE chipsets currently being shipped by Qualcomm support LTE FDD / TDD and 3G multimode, which can meet the 4G LTE deployment requirements of China's three major operators with one platform. More noteworthy is that QRD (Qualcomm Reference Design Platform) is also the industry ’s first reference design project to support 4G LTE. It supports LTE / 3G multi-mode, various positioning systems including Beidou, and supports rich multimedia functions. Help partners achieve "differentiation".
Incremental encoders provide speed, direction and relative position feedback by generating a stream of binary pulses proportional to the rotation of a motor or driven shaft. Lander offers both optical and magnetic incremental encoders in 4 mounting options: shafted with coupling, hollow-shaft, hub-shaft or bearingless. Single channel incremental encoders can measure speed which dual channel or quadrature encoders (AB) can interpret direction based on the phase relationship between the 2 channels. Indexed quadrature encoders (ABZ) are also available for homing location are startup.
