Looking at the future of 5G, it also shows a trend of "from communication, higher than communication". To clarify this trend, let's go back to communication itself and start with a recent news about data calls.
Due to communication, band aggregation greatly improves the performance of 5G.
On April 13, Qualcomm announced that the terminal equipped with Snapdragon X65 5G modem, RF system and Qualcomm QTM545 millimeter-wave antenna module successfully completed the dual-connection 5G data call in Sub-6GHz FDD/TDD band and millimeter-wave band based on 5G independent networking (SA) mode. In this process, the dual-connection data calls of 5G sub-6GHz FDD band and 28GHz millimeter wave band, and 5G sub-6GHz TDD band and 39GHz millimeter wave band are realized respectively.
This news fully demonstrates the powerful ability of Snapdragon X65 in aggregating high, medium and low frequency spectrum to support the global key frequency band combination. Carrier aggregation is the key to continuously increase the peak rate since the 4G+ era. Through the combination of multi-band carrier aggregation, the transmission bandwidth is greatly improved, and finally the peak rate is obviously improved. After entering the 5G era, carrier aggregation's capabilities are constantly developing. Qualcomm Snapdragon X55 has realized the dynamic spectrum sharing between 4G and 5G, Snapdragon X60 has realized the integration of Sub-6GHz and millimeter wave bands, and Snapdragon X65 has started to support FDD-TDD carrier aggregation in 5G uplink.
It is precisely because of carrier aggregation's support for more frequency bands and the improvement of Snapdragon X65' s downlink bandwidth that it can reach 1 GHz in millimeter wave band and 300MHz in sub-6GHz band. Finally, through the dual connection of millimeter wave and sub-6GHz band, it can reach the peak rate of 10 Gbps, which is 100 times higher than the early LTE rate, and finally it is realized in the industry.
This also shows that Snapdragon X65 has achieved forward-looking support for the future deployment of global 5G networks. At present, operators in many parts of the world are deploying millimeter-wave band, and they also choose 4 1GHz band to bring higher peak rate. At the same time, the FDD band on the original 4G network is being released, and 5G is being deployed. By then, Snapdragon X65 will be able to be like a duck to water in the future 5G network, greatly increasing the network capacity and achieving faster transmission rate.
Bury the future and open the era of 10 trillion 5G.
In addition to supporting carrier aggregation in all frequency bands, Snapdragon X65 also embeds cutting-edge technology elements to support the future development of 5G, officially opening the 10Gigabit 5G era.
On the terminal side, Snapdragon X65 and RF system will help equipment keep high speed and power consumption parallel. The matched Qualcomm QET7 100 broadband envelope tracker can support the dynamic adjustment of the amplitude of the power amplifier power supply with the amplitude of the power amplifier transmission signal, realize the on-demand supply of the terminal transmission signal and the power amplifier power supply, reduce the power consumption and prolong the battery life of the equipment; AI auxiliary signal enhancement technology can also greatly improve the experience of mobile phone users in terms of battery life, connectivity, uplink and downlink throughput.
With the freezing of the 5G Release 16 standard in July 2020, it means that the upgraded 5G network will enter a new stage in the future. As an important "big version" iteration, 5G will formally increase the capabilities of URLLC and CIoT from eMBB-based capabilities in R 15, and complete the construction of 5G capability triangle. At the same time, it has better support for making full use of 5G in autonomous driving, slicing network and other fields, and can be expanded in various vertical industries.
Snapdragon X65 is the first modem and RF system supporting the 3GPP version 16 standard. Through the extensible architecture of Snapdragon X65, in the process of network deployment and upgrade, future operators can support Release 16 standard functions in batches through OTA. This also means that by adding new functions, Snapdragon X65 will expand 5G in many application fields other than smart phones.
"This will create new opportunities, such as supporting home gigabit connections, industrial Internet of Things applications and 5G enterprise private networks through fixed wireless access, thus bringing 5G to new industries. For example, a more reliable 5G connection will contribute to the digitalization of manufacturing industry, thus improving the overall productivity in this field. And this is the basis of "Industry 4.0" that people are discussing. " Ma Dejia, senior vice president of Qualcomm Science and Technology Company and general manager of 4G/5G business, said at the X65 conference in Snapdragon before, interestingly, the name of the supporting activities at that time was just "What's the next step of 5G", which also indicates that Snapdragon X65 will play an important role in promoting the arrival of the new 5G era and lead us to accelerate the road to the future.
Higher than communication, set off a new climax of digital transformation
So, how will the future of 5G go?
Obviously, Snapdragon X65 has given the answer. Dr. Nan Mingkai, Senior Director of Business Development of Qualcomm Science and Technology Company, said: "The launch of X65 5G modems and RF systems in Snapdragon has expanded the application scenarios of 5G from traditional consumption fields to more subdivided fields, enabling 5G to better empower vertical industries and help promote the digital transformation of the whole society."
From the perspective of application scope, Snapdragon X65 can not only support traditional applications such as smart phones and mobile hotspots, but also support fixed wireless access, notebooks and tablet computers, and can empower vertical fields such as industrial Internet and enterprise private networks. For example, Qualcomm also released the second generation Qualcomm 5G fixed wireless access platform, which is also equipped with Qualcomm Snapdragon X65 modem and RF system, and adopts Qualcomm QTM547 extended range millimeter wave antenna module.
At present, more fields have shown great enthusiasm for Snapdragon X65. Original equipment manufacturers are accelerating the introduction of CPE equipment using X65. Mobile Communication and Guanghetong have introduced a number of 5G communication modules with built-in Snapdragon X65 5G modem and RF system. With the support of Release 16, they built a bridge between Snapdragon X65 and IOT devices, which enabled the ultra-reliable and low-latency 5G network to be implemented on a large scale in industrial internet, mobile computing, intelligent medical care and private networks.
Recently, An Meng, president and CEO-designate of Qualcomm, also said in an interview with foreign media that 5G is no longer a patent in the communication industry. It will not only be provided to operators and mobile phones, but also become the basic element of the cloud economy. Everything will be connected to the cloud, and 5G will be closely related to the automobile industry, the network sector and the Internet of Things, and provide power for retail, industry and energy.
Undoubtedly, 5G from the communication industry, through carrier aggregation, double connection and other technologies, is still increasing the peak rate and approaching the Shannon limit. At the same time, the significance of 5G is higher and higher than the communication industry itself, because it will support many industries to achieve a new round of upgrading, just like water and electricity are everywhere. In the process of this change, Snapdragon X65 5G modem and RF system undoubtedly marked an important turning point, making 5G originate from communication, begin to surpass communication, and then move towards a new stage.
