At the "2016 China International Information and Communication Exhibition", Zhou Jin, Marketing Director of ZTE Microelectronics Mobile Phone Chip Planning Department, said in an interview with "Since 2014, ZTE Microelectronics 4G multimode chip officially started from ZTE's internal approach to the front office not only provides self-developed terminal chips for ZTE, but also provides 4G multi-mode chip solutions to external customers. Especially after receiving huge investment from the national industry fund, it will plan the layout of 4G terminal chips. It will be more comprehensive and sustainable."

Comprehensive layout of 4G terminal chips

Since 2014, ZTE Microelectronics 4G multi-mode chip has officially moved from ZTE to the front, not only providing self-developed terminal chips for ZTE, but also providing 4G multi-mode chip solutions to external customers.

At present, the main products of 4G terminal chips released by ZTE Microelectronics are ZX297510 solution and ZX297520 solution.

In 2015, the National Integrated Circuit Industry Investment Fund increased its capital by 24 billion yuan, accounting for 24% of the shares. On the one hand, it encouraged ZTE Microelectronics to increase investment in R&D and sales, and also gave a reassurance to the marketization and internationalization of ZTE Microchips. The terminal equipped with ZTE's mobile phone chip has already cooperated in many countries and operators in Europe, South America, Asia-Pacific, Southeast Asia, etc., laying a solid foundation for ZTE's micro-electronic terminal chips to go out to sea.

After ZTE Microelectronics has received huge investment from the National Industrial Fund, the planning and layout of the 4G terminal chip will be more comprehensive and sustainable.

Secondly, the development opportunities of the Internet of Things are coming soon, especially the LTE-based Internet of Things will enter the outbreak phase after 2017. The high spectrum utilization of LTE, based on the IPV6 architecture, brings opportunities for the development of IoT based on cellular networks. ZTE Microelectronics will launch LTE-based CAT1, CAT-M, NB IOT and other series of IoT dedicated chips in the future, continuously reducing chip cost and chip power consumption, providing customers with the best IoT chip platform solution. ”

In addition, ZTE Microelectronics will also use the mature 4G modem technology to build a SOC chip platform for smart phones. Our smart chip platform emphasizes safety and cost performance. At the same time, in the high-end market, we will leverage the leading edge of modem technology and form a differentiated selling point. There will be a more comprehensive layout in the future.

2017 H1 will release NB-IOT commercial chip Wisefone7100

IOT is an important area of ​​wireless communication. According to the report of the consulting company, the number of connections to the Internet of Things will reach 70 billion by 2025, far exceeding the number of links between people and people. ZTE Microelectronics has been working in the field of Internet of Things for many years. It has solutions for many IoT industries such as advertising, energy, monitoring, transportation, measurement, and smart cities. It has achieved scale commercialization and has a deep understanding of the needs of the IOT industry. We also have a large number of IOT customers, as well as mature channels, as well as supporting industry technical support teams.

The needs of IOT are multifaceted and cannot be focused solely on NB-IOT. From now on, the demand for speed develops in two dimensions, high speed and low speed.

In terms of high speed, there are many products using CAT3 and CAT4 in the industry. Some products of CAT6 products have also achieved commercial products, but the shipment volume is not large. However, with the demand for security, advertising, transportation and other business needs, the demand for CAT6 and even CAT12 will gradually increase. This high speed direction will continue into the 5G era.

In terms of low speed, the Internet of Things is facing massive connections. In some IoT scenarios, such as smart meter reading, ecological agriculture, smart parking, smart communities, intelligent buildings, etc., the demand for wide coverage, low power consumption, low cost terminals More specific. The widely used 2G/3G/4G, WLAN and other wireless technologies are unable to meet these challenges, and NB-IoT, the LTE-based narrowband IoT technology, requires these IoT scenarios. In this regard, we have actively deployed, in June this year, China Mobile launched the signaling process of the base station to the NB-IOT terminal, GSMA Shanghai exhibited; this September, the NB-IOT prototype chip was released, Beijing International Communication Exhibition was exhibited; 2017 H1 We will release the NB-IOT commercial chip Wisefone7100.

In addition to the above two directions, there is another technology that needs attention: CAT-M technology. Although NB-IOT is a very important technology of IOT, it can not meet the demand in some scenarios, because it does not support switching, poor support for mobility, especially does not support voice, can not meet the scenes of logistics monitoring, elderly or child monitoring. Demand, and this is exactly what CAT-M technology solves. At present, operators such as ATT and Verizon in the United States attach more importance to CAT-M than NB-IOT, and Chinese operators are also piloting the technology. It is understood that ZTE Microelectronics has completed the pre-research of the agreement and can cooperate with the agreement of the Chinese operator construction plan, sample test and final commercial.

Domestic independent research and development chips break the monopoly of foreign technology

Domestic independent research and development chips break the monopoly of foreign technology. After successful commercialization, it is also a great encouragement for domestic chip manufacturers. This is also the best return for the country to support the chip industry. "For ZTE Corporation, it will play a very important role in further enhancing the core competitiveness of the entire company and mastering the advanced core technology of mobile phone chips. It will also be more calm for ZTE Corporation to cope with the changes in the market. Self-developed chips have more advantages in cost. As an important link in the terminal industry chain, the reduction of chip cost will promote the development of the entire industry and bring more benefits to customers."

ZTE Microelectronics established a mobile phone chip R&D team in December 2005. At present, ZTE Microelectronics R&D department is located in R&D centers in Shenzhen, Nanjing, Shanghai, Xi'an and the United States. The number of personnel has exceeded 2,000, and the master's degree or above accounted for more than 80%. Special algorithm design and simulation, SoC architecture design More than 25 domestic and foreign experts in the field of protocol stack software architecture, and attracted many outstanding professionals from the industry. So far, 15 talents with rich industry experience overseas have been recruited.

In addition, ZTE Microelectronics' customer support team is currently composed of elites from the R&D team. Covering all aspects of technical issues such as baseband, radio frequency, drive, modem protocol, network routing, etc., currently supports more than 20 customers, more than 40 projects, has formal processes and support systems, and responds quickly to problems to ensure that they are met. Customer's product milestone time.

And the customer support team consists of FAE and AE 2 parts, depending on the urgency of the problem, to locate the problem at any time.

ZTE Microelectronics has fully mastered large-scale deep sub-micron digital integrated circuit design technology, SOC design technology, analog and digital-analog hybrid integrated circuit design technology. At present, the maximum size of chips designed is more than 100 million, and the mass production process has reached 28 nanometers. The design conditions include the performance of EDA tools and hardware operating platforms used in the industry.

In the field of 4G communication, ZTE Microelectronics LTE chip has experienced three major stages: from scratch (ZX297500), scale field (ZX297502) to the current batch commercial 28nm LTE multimode chip (ZX297510/ZX297520).
