In the 2013 key strategic plans issued by the three major operators and the predictions of major investment institutions and consulting agencies, in the new year's ICT development trend, wireless communication with LTE as the prominent content still occupies a prominent position. Different from previous years, China's LTE is expected to usher in commercial, cloud computing and big data to promote the upgrade of wireless city architecture, WLAN presents the characteristics of Gigabit wireless connection, etc., becoming a new bright spot in the wireless field in the new year.
1 LTE: Commercial approaching investment becomes rational
According to the latest statistics given by the Global Mobile Suppliers Association (GSA) on January 15, 145 operators in 66 countries have launched commercial LTE services, and in 2012, 104 new operators promised to invest in LTE network deployment To increase the total number of operators committed to deployment to 330 in 104 countries. GSA also predicts that by the end of 2013, LTE commercial networks will reach 209.
The industry predicts that the domestic TD-LTE industry chain will launch a 28-nanometer TD-LTE multi-mode chip, whose performance basically reaches the level of large-scale application, and supports the development and application of TD-LTE smart phones.
2 R11 technical verification is coming
As the evolution technology of LTE, R10, which has been intensively tested in the TD-LTE scale test, mainly focuses on LTE carrier aggregation, uplink and downlink multi-antenna technology enhancement, and interference cancellation between cells. From 2012 to 2013, the industry will discuss and verify R11 enhanced carrier aggregation, CoMP, enhanced inter-cell interference cancellation and other technologies.
In the second half of 2012, 3GPP also initiated the standardization of R12. According to 3GPP standardization experts, R12 will be a milestone version of LTE-Advanced to address the severe capacity and coverage issues in the mobile Internet era.
3 Dual carrier HSPA + becomes mainstream
Although LTE has become the fastest-growing technology in the market, HSPA is still the mainstream technology choice for global operators in terms of commercial volume, and will continue to play the role of "3G leader" in 2013 in the world and domestically.
According to GSA statistics, there are already 254 officially commercial HSPA + networks distributed in 118 countries worldwide, and the number of 42Mbit / s HSPA + commercial networks using dual-carrier technology doubled in 2012 to more than 100. The dual-carrier HSPA + network will become mainstream in 2013. In China, as of the end of 2012, the number of cities where China Unicom opened HSPA + network services increased to 336.
4 802.11ac emergence technology effect
Stepping into the 802.11n era, the pilot of non-aware authentication became the two major characteristics of the domestic operator Wi-Fi market in 2012. On this basis, chip, routing equipment and other manufacturers began to launch a series of 802.11ac products, focusing on the concept of Gigabit wireless network. From a technical point of view, 802.11ac significantly increases the available bandwidth of Wi-Fi links and enhances the functions of various new applications, such as reliable high-definition video streaming, high-speed wireless backup, and data synchronization of mobile devices.
5 New 3G users will exceed 100 million
In 2013, the Ministry of Industry and Information Technology proposed two development goals for the development of the communications industry (newly added 25 million Internet broadband users and more than 100 million 3G users), and vigorously developing 3G users will be the top priority of the three major operators in 2013 weight.
Among them, despite China Mobile's unprecedented investment in TD-LTE, its TD network and user development will still be the highlight of 2013. It is reported that TD network planning, network construction, and network optimization including TD Phase 6 have been considered for TD-LTE.
6 M2M enters a new stage of practical application
In 2013, China ’s leading international organization GTI planned to work with GSMA to carry out LTE TDD / FDD Internet of Vehicles trials and roadshows. This news triggered common concerns in the three major areas of mobile communications, Internet of Things, and automotive informatization. In addition to facilitating the establishment of a cooperative relationship between large automobile manufacturers and operators around the world, the joint research and development of operators and car manufacturers, and the overall optimization of vehicles integrating LTE TDD / FDD business application modules, M2M, represented by Internet of Vehicles, also promotes the future LTE communication module to become A necessary facility for the vehicle.
7 Wireless LAN expansion frequency band
In November 2012, senior officials of the Radio Management Bureau of the Ministry of Industry and Information Technology publicly stated that in order to support the application and development of WLAN, the Radio Management Bureau has planned to plan the three bands of 5150MHz-5250MHz, 5250MHz-5350MHz, and 5470MHz-5725MHz in the 5G frequency band for a total of 455MHz. It is the wireless LAN spectrum. Allegedly, the Radio Administration Bureau of the Ministry of Industry and Information Technology “will release the WLAN frequency plan in due courseâ€.
8 Network isomerization accelerates the popularization of Small cell
In 2012, the popular Small Cell will launch a larger-scale pilot in 2013, leading the network to the actual pace of isomerization. The low-cost, easy-to-deploy, self-configuring, self-optimizing, controllable, and tightly coupled with the macro network of Small Cell will be a very important choice and direction in the future network construction, and will become the future HetNet network fusion architecture An important part of
9 Wi-Fi Perceptionless Scale Promotion
Despite the increasing number of hotspots, the trend of users actively choosing and paying for Wi-Fi in Wi-Fi public hotspot areas is far less rapid than network construction. One of the problems is that the authentication and use process is relatively complicated. In 2012, the Wi-Fi non-aware authentication technology developed jointly by China Mobile-based operators and the industry chain is gradually maturing. The industry predicts that in 2013, Wi-Fi non-aware authentication is expected to be widely promoted and applied.
10 NFC technology expands the scope of application
Distance wireless communication (NFC) has become famous for its use in mobile payment methods in the past two years. In fact, NFC's increasingly significant growth trend will prompt its application in more consumer electronics products, including game controllers, televisions, remote controls, computer keyboards, mice, headphones, printers, and so on. NFC mobile phones with embedded virtual credential cards have a wide range of uses since 2013. NFC-based technical solutions have emerged in areas such as car launch, access control, hotel management, and smart home.
