Qualcomm: Achieving Gigabit LTE download speed is the cornerstone of 5G

5G was originally a next-generation communication technology, and 5G communication standards are still being developed, but recently it has spread all media platforms. Because of the discussion on the 5G short-code scheme at the 3GPPRAN 187th meeting on November 17, the Huawei-recommended Polar code control channel standard scheme was adopted, which caused a strong response from the Chinese. In fact, on October 14, 2016, the LDPC code led by Qualcomm won with a majority vote, and the data code long code block coding scheme adopted by the Polar code was adopted as the 5G eMBB scene. The other two 5G scenarios defined by 3GPPP mMTC and URLLC standards will be determined by 2018, and the 5G standard road is just beginning.

The reverberation of the 5G standard has just passed, and the timetable for China's 5G commercial is officially released. According to media reports, according to the work of the Ministry of Industry and Information Technology, China's IMT-2020 (5G) promotion group and the 5G commercial plans of the three major operators, China will launch the second phase of the 5G network test in 2017 and the large-scale trial network in 2018. On this basis, the 5G network will be launched in 2019, and the official commercial 5G network will be established as soon as 2020.

When it comes to communication technology, it has to mention Qualcomm. As a global wireless technology leader, it has taken the lead in the 3G and 4G eras. In the 5G field, Qualcomm has also had forward-looking research. At present, Qualcomm is leading the development of 5G from all aspects of chips, technology, prototypes and engineering networks. Qualcomm has extended the technology, experience and accumulation in the past 3G and 4G fields to 5G research and development, and has accumulated a large number of achievements, 5G. R&D funding has also invested billions of dollars. In terms of capital investment and patent technology reserves, Qualcomm has surpassed many communication companies.

It is reported that Qualcomm's current research and development investment in the field of communications technology has already exceeded 41 billion US dollars. In the 2G, 3G, and 4G eras, Qualcomm is one of the main participants in the development of technical standards, and has accumulated a large number of patented technologies. These are the cornerstones of the International Telecommunication Union's creation of a globally unified standard in the 5G era.

It is said that 5G is different from the previous 3G, 4G, 5G, what unique experience will bring? What is the role of LTE in the Internet of Things? Let us look at it together, what does Qualcomm say?

Achieving gigabit LTE download speed is the cornerstone of 5G

On November 25th, at the Q Technology LTE and LTE Media Salon for the Internet of Things, Shen Lei, senior director of Qualcomm Technology product market, introduced that in February 2016 Qualcomm launched the world's first commercial Gigabit. Class X16 LTE modem, supporting FDD and TDD spectrum up to 4X20MHz downlink carrier aggregation (CA) and 256-QAM, will bring "LTE-like" LTE Cat.16 download speeds up to 1Gbps, it also passes Supports up to 2X20MHz uplink carrier aggregation and 64-QAM, delivering up to 15Mbps upstream speed.

Shen Lei pointed out that X16 uses three 20MHz carriers, and the data throughput is increased by three times. It supports Licensed-Assisted Access (LAA) for LTE; 4X4 MIMO; support for 256-QAM can be used for each The peak throughput of the data stream is increased by 33% (from 75Mbps to 100Mbps); through carrier aggregation and 4X4 MIMO, the X16 can only accept 10 independent data streams using only 3 20MHz carriers, and the peak data throughput reaches gigabit. For example, among the mobile terminals that have already appeared, Samsung S7 mobile phones have taken the lead in adopting 4X4 MIMO technology.

Regarding the application prospects of Gigabit LTE, Shen Lei describes that Gigabit LTE is critical for the next generation of experience, and will bring subversion in immersive VR, networked cloud computing, rich entertainment and instant Appp applications. Sexual experience. The average rate of Cat 16 LTE is 114 Mbps higher than 120 fps 360 ° 4K shows an average rate of 103 Mbps, almost the same as 4 KB local read speed. The X16 application will bring 360° more than the immersive experience of the flat panel display in the VR device; making the cloud storage have a user experience comparable to the local flash memory read, downloading 203 minutes of lossless music in just 2.4 minutes, download A 20MB app takes only 1.4 seconds.

The next generation of Opteron 800 series processors (such as the Opteron 835) will integrate the X16 LTE modem.

"Gigabit LTE is an important cornerstone for the 5G mobile experience, but 5G is not produced out of thin air. It is a process of accumulation of 4G and other technologies for many years." Shen Lei said, "In the beginning, 4G and 5G will still be very long." Coexisting for a while, just as 3G and 4G are still complementary after so many years, so multimode is very important. Gigabit LTE/5G multimode will also be crucial for the implementation of early 5G millimeter wave networks."

Gigabit LTE can provide a wide-area coverage network for early 5G networks, so he will be an important pillar of the 5G mobile experience.

Qualcomm is the first to release 5G Modem chips

Over the years, Qualcomm has achieved technological leadership and accumulated a wealth of experience in 3G, 4G LTE and Wi-Fi, and is committed to leading the global 5G road. In October of this year, Qualcomm launched the Xiaolong X50 5G modem, becoming the first company to release a commercial 5G modem chipset solution. The X50 initially supports the operation of the millimeter-wave spectrum in the 28 GHz band. It will use MIMO antenna technology that supports adaptive beamforming and beam tracking to achieve stable, continuous mobile broadband communications in non-line-of-sight environments. By supporting 800MHz bandwidth, the X50 is designed to support peak download speeds of up to 5Gbps.

This product can be paired with an Opteron processor with integrated Gigabit LTE modem and closely coordinated with dual connectivity to support OEMs to build next-generation cellular terminals and assist operators in early 5G trials and deployments with the goal of accelerating 5G Standardization and commercialization of the global standard brick 5G NR. The X50 is expected to begin sampling in the second half of 2017, and the first commercial products incorporating the X50 are expected to be available in the first half of 2018.

The millimeter wave means the ultimate bandwidth, but the limitations of the millimeter wave are also very obvious. For example, the transmission distance is short, and obstacles will block the connection. On how to solve the shortcomings of millimeter waves, Shen Lei said that the use of its millimeter wave high frequency characteristics can fully compensate for the disadvantages. The millimeter wave wavelength means a smaller antenna that can be plugged into multiple antennas to form an antenna matrix. Qualcomm uses advanced beamforming technology and uses a large number of antenna technologies to ensure that the user terminal remains connected while moving. In non-line-of-sight and mobile scenarios, millimeter-wave technology can take advantage of the reflection of buildings or surrounding objects to maintain a link between the base station and the terminal.

Regarding 5G, we are more focused on the support of millimeter waves, but 5G is not equal to millimeter waves. 5G technology is not a technology that can only use one frequency band. Qualcomm's unified 5G design supports all spectrum types and frequency bands.

Shen Lei said that in the future, 5G terminal equipment must not only support all spectrum types and frequency bands, but also have 5G, 4G and WiFi simultaneous connections. According to the actual situation of different links, some services only pass 4G, some pass 5G, some pass Wi-Fi, and three links will serve users at the same time. This also makes the management of the service more efficient and the user experience becomes better and better.

LTE IoT technology for the Internet of Things

Now that we are in an era of transition to new technologies, mobile communication technologies are spreading to the adjacent industries with smartphones as the center, and billions of devices will be connected. We call them the Internet of Things. At present, Qualcomm's products and services are not limited to mobile smart terminals, and have been extended to medical, automotive, Internet of Things, smart home, smart city and other fields.

LET provides a solid foundation for the growth of the Internet of Things based on wireless cellular technology. According to Shen Lei, it currently covers more than 5,100 terminal products from more than 160 countries and 400 manufacturers. It is understood that these modems are compatible with the world's major cellular standards, while also supporting Linux OS, ARM Cortex A7 processor, and pre-integrated Qualcomm supporting MU-MIMO technology? VIVE? 802.11ac Wi-Fi, Bluetooth 4.2, Bluetooth Low Energy, and Global Navigation Satellite System (GNSS).

More than 5 billion IoT connections by 2025. Cellular technology will support a wider range of IoT services, new narrowband technologies will support IoT applications more efficiently, ubiquitous coverage (anywhere), always-on connectivity (anytime), and a secure, optimized global ecosystem The system will become a trend in the future.

LTE LoT is of great value in low power wide area applications. Shen Lei said that both Cat-M1 and Cat-NB1 have low cost, low power consumption, long battery life and a wider network coverage. Among them, Cat-M1 has relatively fast data transmission, extreme mobility, support for voice/VolTE, etc. Two AA batteries can be used for ten years; Cat-NB1 has ultra-low cost and ultra-low power consumption. Low-throughput IoT applications, such as remote sensors, can last for more than 10 years with two AA batteries.

It is understood that Qualcomm's MDM9X07 LTE modem (supporting Cat1, Cat4) for the Internet of Things has received more than 100 terminal designs from more than 60 manufacturers. Qualcomm's latest IoT solution – an MDM9206 LTE modem for battery-powered sensor applications has been designed by most industry-leading OEMs and module manufacturers. The 9206 supports LTE Cat M1 and can be upgraded to support Cat M1 and Cat NB-1 dual mode with upcoming software updates.

In addition, with the support of 3GPP global standard rich 5G circuit diagram, LTE physical network technology will continue to be based on 3GPP Release 13 and add new features, such as support for multicast and positioning, for narrowband 5G Internet of Things. Lay the foundation.

Shen Lei concluded that LTE is evolving to provide a scalable unified IoT platform, which brings great advantages over non-3GPP low-power wide-area solutions; LTE IoT provides new narrow-band IoT technology to reduce complexity and improve Battery life and deeper coverage; LTE IoT will bring more opportunities to the Internet of Things, including new mission-critical services. Qualcomm Technologies is helping evolve LTE to achieve a scalable, unified IoT platform with the unique advantage of connecting the Internet of Things.

With the development of technology, people's demand for communication has gradually become indispensable. In the future, mobile phones and computers may no longer be in the current form. Instead, they will be a table, a chair, a car, a wall... All objects have wisdom, they can connect with each other, and even the human body will be implanted into the chip. I believe that you have heard a lot of such stories, but what you are saying today is that this is all in sight, because the upcoming 5G era will completely disrupt the human data life.

After the media communication meeting, Jiwei also visited the Qualcomm Shenzhen Innovation Center, which is equipped with several leading laboratories and established the world's first wireless communication and Internet of Things "technology exhibition center" outside the United States. The small display center brings together Qualcomm's leading technologies and solutions in the fields of wireless communication and Internet of Things, covering 5G, drones, virtual reality, robotics, smart home and other fields.
