This summer, the world has set off a football fever. The eyes of hundreds of millions of people focus on Russia and pay attention to the four-year World Cup. For most fans, it is too far away to go to the scene to cheer for their favorite players. Watching the live broadcast in front of the TV is perhaps the most common way. But this way of watching our parents have become accustomed to it, it is difficult to meet our experience now, and it is urgent to bring new technologies to bring about new changes.
Coincidentally, in the morning of the World Cup kick-off, the 3GPP Plenary approved the fifth-generation mobile communication technology standard (5G NR) independent networking function freeze, plus the non-independent networking NR standard completed in December last year, marking 5G The first phase of full-featured standardization has been completed, and the formal commercialization of 5G is getting closer.
Looking back at the past few World Cups, in 2006 we learned about Zidane’s sorrowfulness through MMS. In 10 years, we paid attention to the doorsteps of England through Weibo. In 14 years, we directly witnessed the German slaughter of Brazil by mobile phone. The change of communication technology directly affects our viewing experience. 5G is the technical explosion point of the next revolution, and the viewing experience will be different.
High speed and low latency, 5G viewing experience is very different
5G networks cover a variety of application scenarios, including enhanced mobile broadband, mission-critical services and massive IoT. As far as our viewing experience is concerned, the most direct impact is enhanced mobile broadband, its high data throughput, low The delay characteristics can fully meet the timely transmission of high-resolution media. It is no longer easy to deal with the current mainstream 4K live broadcast. You can even receive signals from more than 30 8K cameras at the same time, paying attention to the game's every move, according to your own There is no slight delay in switching the viewing angle.
If this is not enough, the VR live broadcast under 5G directly meets your desire to 'do not go live on the spot', the VR live stun stunned, the lack of immersion is solved under the 5G high rate, low latency characteristics. On the VR glasses, C Ronaldo gallops from your side, Neymar is in front of you, picking the ball, and you are in the shouts of thousands of fans in the audience, fully enjoy the origin Passion for football.
It is not limited to the rear viewing experience. Even if you are at the scene, you can feel the direct change brought by 5G. Large venues are often the hard-hit areas with high user density, and tens of thousands of people concentrate on communication, which is a huge network capacity. The challenge of 5G through massive MIMO technology, deploying a large-scale antenna array at the base station side, and simultaneously serving multiple on-site users with the same time-frequency resources, thereby greatly increasing the capacity, without the presence of signals but not on the network. Happening.
5G standards are gradually improved, behind the giants
Nowadays, the 5G standard is gradually perfecting, and the transformative experience is coming to us. This is naturally inseparable from the support of technology. As a mobile communication leader, Qualcomm is the first to participate in 5G basic research and invention, with strong technical accumulation and continuous Promote the evolution of 5G.
In the early 2016, Qualcomm has demonstrated the 28GHz millimeter wave prototype system and the 5G NR prototype below 6GHz, and based on this, it achieved the world's first 5G data connection at 28GHz in 2017. Qualcomm-led LDPC code can withstand the harsh The channel condition, with high-speed and low-latency characteristics, has been confirmed by 3GPP in the data channel of 5G NR eMBB (Enhanced Mobile Broadband) scenario.
More importantly, Qualcomm is actively engaged in interoperability and OTA testing with major global carriers and network infrastructure vendors such as AT&T, Vodafone, China Mobile. In 2017, China Mobile and ZTE completed the world's first 3GPP R15-based standard. The end-to-end 5G new air interface system interoperability has made an important milestone in 5G commercial.
Leading technology put into practice, Qualcomm sets an example
Leading technology is not just in the lab, it is put into practice, and concentrating on products can bring about real change. In October 2016, Qualcomm launched the world's first 5G modem, the Snapdragon X50 5G modem, to achieve 5Gbps. Download speed. At present, Qualcomm's commercial X16 LTE modem and X20 LTE modem have 1Gbps and 1.2Gbps Gigabit speed respectively. The two are integrated into the two flagship SoCs of Xiaolong 835 and Xiaolong 845, which become the transition to 5G. key.

Based on the Snapdragon X50 5G modem, Qualcomm released the first 5G smartphone reference design in October last year, which means Qualcomm has ample maturity in the RF front end, antenna and modem of 5G mobile phones, making 5G on the terminal side. bedding.
At the beginning of this year, Qualcomm and domestic mobile phone manufacturers actively launched the 5G pilot program, providing a complete system-level modem-to-antenna RF front-end platform solution portfolio to help domestic manufacturers design leading terminals that meet Gigabit LTE and 5G networks. In the 5G era, one step ahead. Without any surprise, the first 5G mobile phone will be unveiled in 2019, and it comes from Chinese mobile phone manufacturers.
Radiation in more fields, 5G experience is not far away
Qualcomm has the core technology advantages of 5G development, and its Snapdragon platform with integrated Gigabit demodulator is widely used in mobile terminals, and actively cooperates with operators and terminal manufacturers to help the latest technology realize business in a short time. , ready for 5G.
It is believed that under the main force of many communication manufacturers, the revolution of 5G on the live broadcast of the event is only the beginning, and the future is bound to radiate more fields. Unmanned driving becomes a reality, the car is really smart, and passengers can be safely delivered to the destination through voice control. Our wearable devices will all be connected to the network, so that the data can flow effectively and help to monitor the physical condition at any time. 5G will affect all aspects of us in a subtle way, and these wonderful experiences are not far away from us.
