First, Qualcomm marketing director Ignacio Contreras shared the development of Qualcomm IoT-related business. He said that Qualcomm currently ships more than one million IoT chips every day. It is estimated that our revenue in the Internet of Things will exceed 1 billion this fiscal year. USD. In the future, Qualcomm will also bring R&D investment in the field of mobile communications into the fields of automobiles and Internet of Things to promote the development of the Internet of Everything.
In IoT applications, connectivity is a key link. At present, WiFi, Bluetooth, LTE and other technologies are mainly used. Qualcomm not only has technical advantages but also rich product iterations. It introduces SoCs and software systems suitable for different terminals. Development tools, it can be said that Qualcomm has many inherent advantages in the field of IoT connectivity. At the same time, Qualcomm's accumulation in AI will also be applied to the Internet of Things ecosystem. Ignacio Contreras talks about the Qualcomm visual intelligence platform launched in April 2018. It has taken advantage of Qualcomm's technological advantages in the AI field, and these advanced technologies will be applied to more products. It is worth mentioning that Ignacio Contreras specifically talks about China as an important Internet of Things market, the report pointed out that by 2020, China The industry scale of the Internet of Things will exceed 1.5 trillion yuan, and Qualcomm will use its technological advantages to help Chinese partners and ecosystem development.
Then Gopi Sirineni, vice president of product management at Qualcomm, gave a detailed introduction to the current hot smart home networking solution. He said that with the popularity of terminal devices, the number of home networking terminals has increased rapidly. The market analysis report shows the networking of family of four in 2017. There are more than 20 terminals, and 50 will reach 50 in 2022. With the increase of data volume, especially the amount of data used by terminals such as TVs and speakers will be considerable, which puts forward the connection of terminal equipment. higher requirement.
Gopi Sirineni said that according to the survey data for consumers, about 60% of users are dissatisfied with their own routers. The main problems are concentrated in WiFi coverage, peak connection efficiency and poor experience when accessing new terminals. Connected to a connected terminal device, Gopi Sirineni talks about Qualcomm's connection experience from connectivity, perception, interaction and security.
Gopi Sirineni introduced that Qualcomm proposed the concept of Wi-Fi SON three or four years ago for the needs of the home Internet. SON (Self-Organizing Network) literally translated as a self-organizing network, now commonly known as mesh network. There are many key features of the solution, some of which are self-organizing networks. Compared to the traditional way of buying a Wi-Fi gateway to go home, the so-called mesh network refers to a set of three pieces, four pieces at home. Installed, even six pieces of Wi-Fi networking equipment. One of them can be connected to the uplink network, and the other will be automatically organized into an Internet. The terminal in the home will connect to a specific network node nearby. On the one hand, according to the strength of the signal, on the other hand, according to the environment interference, which network node can provide the best bandwidth. In the case of the self-organizing network, the scene of the user experience can be optimized. For example, some home terminals It is accessed by a tablet computer, and some terminals are playing video. According to different terminal bandwidth and delay requirements, users can set different frequency bands of 2.4G or 5G, or Access different network nodes, which provides a lot of self-optimizing functionality and space to improve the user experience.
The other aspect is the self-repair function. For example, the camera installed in the home usually only works at a specific time, or it can detect that there are moving targets in the home to work. On the self-organizing network, the working condition of the camera is different from the normal usage. It is found that the camera works during the period when it is not supposed to be turned on, or the data captured by the camera is inconsistent with the situation of the usual use. The self-repair function of the self-organizing network can be monitored according to the situation in which the user usually uses the camera, and the situation is changed to the user. Provides an alarm and even isolates the terminal for protection. Another example of network self-repair is to access a router at home in the traditional way. If the router is damaged, the network in the home is basically paralyzed and cannot be connected to the terminal. -Fi connection. For a mesh network solution with multiple nodes, if one node fails, the data stream will be automatically connected to other nodes, and even the connection of the terminal can be realized by other network nodes. Robustness, anti-jamming and anti-destructive capabilities are superior. Moreover, mesh Wi-Fi To the heart of the city, allowing high-density living environment benefit.
In general, mesh networks are more 'smart' than traditional single-node networks, reducing mutual interference and enhancing signal coverage, thereby improving the overall user experience. More importantly, devices under 'smart' mesh networks The interconnection is not only networked but can be intelligently adjusted according to the user's usage status. For example, Qualcomm's audio solution can be used to realize sound biometric recognition, complete voice wake-up and other functions, or use camera detection to achieve security, terminal intelligent control and other functions. Powerful, but Gopi Sirineni talks about the current mode of mesh network in China, there is no very large access rate, but there is a large demand, there is market space.
Finally, Qualcomm product marketing director Liu Junyong introduced Qualcomm's progress in the audio field, including true wireless technology (TrueWireless Stereo and TrueWireless Stereo Plus), Qualcomm aptX and recently announced aptX Adaptive audio technology.
Liu Junyong said that the personal audio market including Bluetooth headsets, wired headsets, active noise reduction (ANC) headsets, and the speaker market are two important blocks in Qualcomm's focused market segment. Taking Bluetooth headsets as an example, wireless Bluetooth in the last two years. Headphones have become the first choice for many mobile phone users (especially after the 3.5mm headphone jack is gradually removed), but due to the limited size, these types of headphones need to consider the battery life while ensuring comfort. Therefore, it is necessary to control the power consumption of the chip to meet the requirements. For this demand, Qualcomm's products not only have ultra-low power consumption, but also guarantee high sound quality and noise reduction.
Qualcomm has done more to improve the user's audio experience. Liu Junyong said that for the frequent use of mobile phones connected to smart phones, Qualcomm has introduced true wireless technology, and offers different technologies, TrueWireless Stereo and TrueWireless Stereo Plus, depending on the handset. , Cover more terminal equipment to make users feel more sound quality.
As the focus of the audio part of this media communication, Liu Junyong introduced Qualcomm aptX and aptX Adaptive audio technology in detail, which can be said to be an important boost to enhance the smart speaker experience.
Qualcomm aptX has three versions: aptX Classic, aptX HD technology and aptX low latency technology, which can effectively improve the sound quality of the device. According to Liu Junyong, as of the third quarter of 2018, Qualcomm has been around 540 in the entire ecosystem. Brand or software has signed a licensing agreement; has about 460 licensees; supports more than 300 source devices including mobile phones, PCs and tablets; and has about 1000 types of receiving terminal devices including headphones and speakers. aptX technology; in terms of the number of devices, about 4 billion devices support aptX encoders; about 150 million devices support aptX decoders.
aptX Adaptive is an audio codec that Qualcomm announced on August 31 this year to support dynamic adjustment. aptX Adaptive technology can automatically adjust to provide the best sound quality or low latency based on the type of content played on the terminal. The external RF environment is also considered to support robust connectivity. According to Qualcomm, aptX Adaptive decoders for headsets, headsets and speakers are expected to be available in Qualcomm CSRA68100 and Qualcomm QCC5100 series starting September 2018. The Bluetooth audio SoC is available to customers. The version of the aptX Adaptive encoder for terminals such as smartphones and tablets is expected to be available on Android P starting in December 2018.
Liu Junyong also mentioned that aptX Adaptive has several important features: First, the technology will dynamically adjust performance according to the external RF transmission environment; Second, high quality; Third, aptX Adaptive will be backward compatible with all current markets. aptX and aptX HD products, without user control, adaptive completion. As a result, aptX Adaptive has high stability, high quality and low latency, not only to enhance the audio and video listening experience, but also to the player's gaming experience. Improvement. For example, 'Eat Chicken' students know the importance of audio. If there is no better stereo effect and low delay guarantee, it is very likely to be inexplicable... cool!
So in summary, audio has become an indispensable part of the experience of many terminal devices such as mobile phones, speakers, etc. It is an effective way to enhance immersion. At the same time, Liu Junyong also believes that with the popularity of voice assistants (interactive), future audio The space for play is even greater, and Qualcomm's own hardware, technology and other advantages will be further developed to provide more accurate, efficient, stable connection protection and high-quality sound for products such as 'smart speakers'.
