Please recall how 5g was first introduced to the world? The network speed is 100 times that of 4G era, and the peak speed is from 10Gbps. At the same time, this technology can be called the fourth industrial revolution, which can benefit all things and change the mode of production.

The above can be said that 5g started to blow down in the 4G era. However, in terms of peak speed alone, the speed of 5g network has not reached 10Gbps, and there is little support for industrial use cases under R15 specification.

However, with the release of snapdragon x655g modem and RF system, 5g’s reputation will come true.

10Gbps cattle come true

Before the release of snapdragon X65, the fastest baseband was the MediaTek M80 released a few days earlier, with a downlink rate of 7.67gbps. The peak speed of snapdragon X60, the previous generation of snapdragon X65, is 7.5gbps. Although the peak rate has obvious advantages over 4G, there is still a certain distance between 5g and 10Gbps.

On February 9, Qualcomm officially released the snapdragon x655g modem and RF system. The peak speed of the product can reach 10Gbps, becoming the fastest baseband at present, and the first product in the world to enter the 10Gbps mark. This means that 5g terminal products equipped with snapdragon X65 in the future will have the capacity of peak speed of 10Gbps.

Will 5g replace fixed broadband?

At the same time, in 2021, 5g deployment in various regions of the world will begin to have the ability to provide users with 5g network with higher peak rate. One of the important factors is that millimeter wave network will be further deployed. Among them, the United States, Europe, Japan and Southeast Asia have already carried out commercial deployment of millimeter wave. It is expected that other European countries such as Germany, Britain and Italy, as well as South Korea and Australia will carry out commercial deployment of millimeter wave in 2021. The deployment of millimeter wave also means that operators have the ability to provide users with peak speed up to 10Gbps. In this regard, the high pass qtm545 millimeter wave antenna module matched with snapdragon X65 also adds support for the 41ghz band. The downlink bandwidth of snapdragon X65 has also been greatly improved, with millimeter wave band up to 1GHz and sub-6ghz band up to 300MHz.

In addition, faster speed does not mean higher energy consumption. With the introduction of the 7th generation broadband envelope tracking technology into the Qualcomm snapdragon X65, the new Qualcomm qet7100 broadband envelope tracker can improve energy efficiency by 30%, save mobile phone space and support multiple 5g and 4G power amplifiers. Qualcomm also introduced AI into the antenna tuning system for the first time, and launched the auxiliary signal enhancement technology of Qualcomm AI, which can use AI to intelligently detect the hand holding the mobile phone, and dynamically tune the antenna, so as to realize the experience of lower call drop rate, faster call rate, better coverage and longer service life.

In addition, according to the information provided by Qualcomm, snapdragon X65 has been provided to customers for sampling, and commercial terminals based on the two modem and RF solutions are expected to be available in late 2021. This means that 5g will officially enter the 10Gbps era in 2021.

The fourth industrial revolution is coming true

Xiaolong X65 has a wide range of applications. In addition to traditional applications such as smart phones and mobile hotspots, Xiaolong X65 can also support fixed wireless access; In addition to handheld products, snapdragon X65 also supports laptops, tablet computers, and other vertical industries such as industrial Internet and 5g enterprise private network.

“The launch of snapdragon x655g modem and RF system enables Qualcomm to better serve our customers, expand 5g application scenarios from the traditional consumption field to more segmentation fields, enable 5g to better empower the vertical industry, and help promote the digital transformation of the whole society.” Dr. Nan Mingkai, senior director of business development of Qualcomm technologies, said at the media conference. As we all know, one of the biggest highlights of 5g is not only supporting TOC business, but also enabling a wide range of vertical industries.

In addition, it is worth noting that snapdragon X65 is the first modem and RF system to meet 3gppr16 specification. At the same time, it also has an upgradable architecture, which can quickly support R16 specification features in batches through software upgrade according to 5g deployment of different operators.

As an important iteration of 5g standard, R16 specification includes the triangle construction of 5g capability, including ciot (supporting massive IOT terminal access) and urllc; On the basis of basic ability, the network slicing ability is improved by ENS; In terms of vertical industry expansion, vericallan is used to realize customized network capability for different industries, and 5gv2x architecture is determined to support L3-L4 autopilot. In other words, Xiaolong X65’s support for R16 specification makes it have a stronger ability to enable vertical industries.

The alternative to fixed broadband is coming true

5g is also responsible for solving the problem of the last kilometer of optical fiber into the home, but at present, the coverage capacity of 5g signal in indoor environment will be greatly reduced. In addition, different from 5g network connected by a single device, it can replace the traditional fixed broadband, and also requires the network capacity.

Previously, the first generation of Qualcomm 5g fixed wireless access platform launched by Qualcomm in 2019 greatly simplified and promoted the popularization of fixed wireless access terminals. In 2020, Qualcomm will also work with operators and other technology companies to achieve a record Gigabit transmission rate over a communication distance of more than 7km based on 5g millimeter wave.

Along with the release of snapdragon X65, Qualcomm has also launched the second generation of Qualcomm 5g fixed wireless access (FWA) platform, which is equipped with the Qualcomm snapdragon X65 modem and RF system, and adopts the Qualcomm qtm547 extended range millimeter wave antenna module, which can support sub-6ghz 8-channel reception and support the Qualcomm dynamic antenna tuning technology.

Qualcomm qtm547 extended range millimeter wave antenna module provides an extended range solution for 5g fixed wireless access, and extends the performance of snapdragon x655g modem and RF system. It provides a complete platform from modem to antenna for high-performance 5g millimeter wave CPE design, and will help terminal manufacturers develop 5g fixed wireless access terminals faster and more cost effectively.

In other words, on the one hand, when the rate exceeds 10Gbps, on the other hand, it further improves the network capacity, so that both families and enterprises can confidently replace DSL, wired or optical fiber with plug and play 5g solutions. At the same time, it is also expected to solve the deployment problems of operators in fixed broadband services. In the case of saving a lot of labor costs, the corridor of the community with network cable and optical fiber flying across, and the indoor wiring that is not elegant will be gone forever.
