"Two years ago, Qualcomm announced the launch of the world's first 5g modem Xiaolong X50 in Hong Kong to support mobile phone manufacturers to build the next generation of cellular devices. Today, also in Hong Kong, at Qualcomm's 4G / 5G summit, Qualcomm and 5g eco chain partners jointly announced a series of heavy news on 5g progress. For example, Qualcomm and Ericsson successfully completed the first 5g new air interface (5g NR) OTA call below 6GHz conforming to 3GPP specification by using mobile phone sized terminals; Android mobile phone manufacturers will launch 5g mobile phones based on X50 in the first half of 2019; The 5g small base station cooperated by Qualcomm and Samsung will be sampled in 2020.
So, how does Qualcomm work with its partners to promote the commercial use of 5g? Is 5g commercial next year worth looking forward to?
5g compliant calls have been implemented
Last month, Ericsson made the world's first 5g call using a smart phone shaped mobile device. It is reported that the first 5g call was made in Ericsson's laboratory in hista, Sweden, using 39ghz millimeter wave spectrum, Ericsson's commercial 5g NR air 5331 base station, and test equipment using Qualcomm snapdragon X50 5g modem and wireless sub module.
At today's Qualcomm 4G / 5G summit, Qualcomm and Ericsson announced that they have successfully completed 5g new air interface OTA calls conforming to 3GPP rel-15 specification in the frequency band below 6GHz using a mobile test terminal the size of a smartphone. It is understood that the call is conducted in Ericsson's laboratory in Stockholm, Sweden. It is based on the 3.5GHz frequency band. Similar to the first OTA call completed in September based on the 28ghz and 39ghz millimeter wave frequency bands, calls below 6GHz adopt Ericsson's commercial 5g new air interface radio air 6488 and baseband products, as well as mobile test terminals integrating Xiaolong X50 5g modem and RF subsystem.
In addition to sharing this important progress, Qualcomm president Cristiano Amun also demonstrated the world's first 5g HD video live demo at the summit. Interestingly, stiano Amun also took out his mobile phone and made a comparison with the demonstration terminal. It can be seen that the demonstration terminal is larger than his mobile phone.
It is undeniable that the OTA call completed by Qualcomm in cooperation with Ericsson is another important milestone for 5g. The successful completion of 5g calls conforming to 3GPP specification below 6GHz and millimeter wave band means that Qualcomm and Ericsson can provide support for the deployment of 5g new air interface network of mobile operators. Ma Dejia, senior vice president of Qualcomm engineering technology, said: "the spectrum below 6GHz is of great significance to the global 5g new air interface deployment. It can provide high-performance wide area connection, and has been distributed and auctioned in many regions around the world, including the United States, South Korea and Europe. Other regions are also expected to complete these work in the near future. We look forward to continuing to cooperate with Ericsson to help the mobile ecosystem achieve 5g business. "
However, as mentioned above, the terminals that complete 5g standard calls are larger than the common smart phones. Will 5g mobile phones be larger?
5g mobile phone will arrive in the first half of 2019
Of course, the answer is no. We know that due to the increasing complexity of RF in the 5g era, carrier aggregation is required for both 5g independent networking and non independent networking, the combination of frequency bands will increase exponentially, and 5g millimeter wave also needs antenna array. Therefore, the test equipment will be larger than commercial mobile phones, But it will eventually be as thin as a 4G phone. To this end, in July this year, Qualcomm launched the world's first fully integrated 5g new air interface millimeter wave and below 6GHz RF module for smart phones and other mobile terminals, which can cooperate with Xiaolong X50 5g modem to provide multiple functions from modem to antenna and cross frequency band, and support compact package size for mobile terminal integration.
At the 4G / 5G summit three months later, Cristiano Amun announced the launch of the latest "small" new product of Qualcomm qtm052 millimeter wave antenna module series for smartphones and other types of mobile terminals - fully integrated 5g new air port millimeter wave module. The newly launched millimeter wave antenna module is 25% smaller than the first batch of qtm052 millimeter wave antenna modules released in July. The fully integrated 5g new air port millimeter wave module adopts the design of phased antenna array and supports extremely compact package size. A smartphone can integrate up to 4 modules, including integrated 5g new air port radio transceiver, power management IC, RF front-end components and phased antenna array, It can support up to 800MHz bandwidth in 26.5-29.5ghz (n257) and complete 27.5-28.35ghz (n261) and 37-40ghz (n260) millimeter wave bands.
Cristiano Amun pointed out: "Qualcomm has been exploring ways to innovate the mobile experience. The qtm052 millimeter wave antenna module announced today is the result of our efforts. We are committed to allowing OEMs to have broader imagination and design freedom when building the shape scheme of 5g smart phones, which is being realized through Qualcomm's breakthrough innovation in the miniaturization of 5g new air port millimeter wave modules. At the same time, this landmark innovation has further consolidated Qualcomm's leading position on the 5g commercial road in early 2019. "
What's more exciting is that after announcing the launch of the smallest millimeter wave antenna module, Cristiano Amun took out the reference design product of 5g mobile phone that Qualcomm will launch in the first half of 2019, and again compared it with the 4G mobile phone he is using. The results show that the two phones have very similar dimensions and thickness. He said: "the flagship mobile phone products built by mobile phone manufacturers using Xiaolong 800 series and X50 are expected to be launched in 2019, and consumers should be able to enjoy them in the second quarter“
So, who will be the first to launch 5g mobile phones? Probably the mobile phone manufacturers that initially joined Qualcomm's 5g pilot program, including Lenovo, oppo, vivo, Xiaomi, ZTE and Wentai technology. Oppo previously said it would work closely with Qualcomm to launch 5g mobile phones as soon as possible. At the summit, Pei Yu, co-founder of Yijia technology, when asked when Yijia will launch 5g mobile phones, said that Yijia is a relatively small mobile phone company. Of course, we win the trust of consumers with our products. We will continue to pay attention to the progress of 5g and maintain cooperation with Qualcomm. The time to launch 5g mobile phones is still to better meet the needs of consumers.
Is the 5g network ready?
Only terminals can not realize 5g commercial, and infrastructure is also very critical. "In the 5g architecture, 5g relies on the 4G underlying network to provide coverage, and can also support fast switching with 4G networks," Christiano Amun said in response to media questions He also pointed out that 5g will become a commercial reality in 2019. When we met here a year ago, it was just an ambition. Today, 5g is already a reality. Where the line of sight is accessible, different countries have plans to evolve to 5g in the first half of 2019. The change we see is that some places used to focus on deployment below 6GHz, but now they also focus on millimeter wave, such as North America. In addition, millimeter wave and deployment below 6GHz are also piloted in Japan and South Korea.
However, the 5g new air interface network will use the high frequency band below 6GHz and millimeter wave. In order to efficiently expand the 5g new air interface network, the whole industry will increasingly rely on small base stations as the cornerstone, especially in the indoor environment where most data consumption occurs. It is reported that global mobile operators, including the United States, Japan and South Korea, are expected to deploy small base stations.
In order to meet the cost and product dimension requirements of various 5g new air interface deployment scenarios, we saw Christiano Amun and Dr. woojune Kim, senior vice president of Samsung, jointly announce at the summit that the Samsung 5g small base station solution based on fsm100xx will begin to be sampled in 2020.
It is reported that today, the world's mainstream operators have invested billions of dollars in network deployment in order to prepare for 5g commercial use in 2019. However, many people in the industry are worried that the high cost of small base stations may affect the development of 5g. For this, rasmus Hellberg, senior marketing manager of Qualcomm, said: "5g deployment can make full use of the existing LTE network. More small base stations are needed to realize millimeter wave, but more importantly, 5g cost is related to existing assets and coverage."
Are you ready for 5g?
5g infrastructure and terminals are ready. What can 5g bring? Cristiano amon said: "the difference is that when we discuss 5g, we no longer discuss voice services. All 5g networks focus on data, only data." What is the most direct feeling of 5g's high rate, low latency and large connection for ordinary consumers? At the summit, Microsoft vice president Erin Chapple said that 5g will be able to realize uninterrupted network connection devices, such as laptops based on Xiaolong 835 and Xiaolong 850. She believes that human beings need water, air and connection in the future. Wu Dan, general manager of Tencent intelligent innovation business department, said that 5g higher speed and lower delay will bring a different game experience. Dave Cole, co-founder and CEO of nextvr, said 5g is an important technology for VR, which will enable us to have a better VR experience.
With regard to 5g applications, Ma Dejia also said: "in addition to mobile devices such as mobile phones and XR, 5g connects terminals and edges, which can expand the network to industrial Internet of things, automotive communication and other fields." At the summit site, Shen Ziyu, vice president of Geely Automobile Research Institute, said: "Geely now has 4G modules in every car and uses Qualcomm chips. In the future, it will turn to 5g. We hope that Geely Automobile 5g users can reach 10 million in 2021. According to statistics, at present, many people are in the car for one hour a day, so the car needs better connectivity. Now the car can provide music, navigation and in car assistant services. " In addition to the car entertainment system, 5g will also be an important technical guarantee for the realization of auto driving.
In the industrial field, venkatarayalu, vice president of Honeywell, said that in industrial applications, such as in the isolation area, the safety of workers in the isolation area can be better guaranteed through 5g connection. In the fire field, real-time data transmission is very important. In any case, 5g will show greater potential in the industrial field. He also revealed that Honeywell will switch from 4G to 5g next year. In the retail field, Philip Thompson, global technology leader of Amazon retail, said that the next generation of retail stores will be connected by Amazon IOT + WiFi + 4G / 5G, and displayed an AR shopping video based on 5g technology.
In addition, 5g network can also create many new opportunities, such as automatic guided vehicle (AGV) relying on high-speed and safe wireless link to realize industrial automation. 5g spectrum can also provide opportunities for thousands of megabits of wireless rate, making it an ideal solution for fixed wireless access (FWA) applications, providing "last mile" broadband connections for families, apartments and other venues in areas where traditional optical fiber or copper infrastructure is difficult to serve.
In other words, 5g network will use small base stations to provide thousands of megabits of throughput and millisecond delay to improve the wireless experience and support diversified emerging applications, such as augmented reality and virtual reality, industrial manufacturing, automobile, retail, health, smart city, energy, etc.
For 5g, a market with a scale of 12 trillion in 2045, 5g has attracted many manufacturers, but 5g has not yet been implemented. At this time, both technology and industrial chain need to be continuously improved. There are many challenges to be solved to realize 5g network with high rate, low delay and large connection. Therefore, 5g experience may not be perfect in the early stage of business, However, with the emergence of new applications and related content, we will certainly feel the different charm of 5g in the end.
As a company that is good at communication technology, Qualcomm has cooperated with OEMs, ODMs, operators, parts manufacturers, software developers, channels and content providers in the industrial chain to build a 5g ecosystem and jointly promote the landing and maturity of 5g. Nearly 2500 participants of Qualcomm 4G / 5G summit this year are also the best proof of the industry's expectations for 5g business.
