In recent years, with the comprehensive coverage of the mobile Internet, China's smart phone market has ushered in rapid development. Mobile payment, digital office, smart life and other application fields have transformed mobile phones from a single communication tool to a core connector for digital life. At the same time, in the face of consumers' continuous pursuit of faster and smoother interconnection experience on mobile devices, 5G technology has been rapidly promoted in China. By the end of 2021, my country has built more than 1.42 million 5G base stations, covering all prefecture-level cities and 98% of counties. It is estimated that in 2022, the total number of 5G base stations will exceed 2 million, and the overall sinking from cities to villages and towns will be realized. At the same time, the popularity of 5G networks has prompted the smartphone market to tilt towards the industrial resources of related equipment. From January to February 2022 alone, 5G mobile phone shipments in the domestic market will reach 37.7 million units, accounting for 78.7% of mobile phone shipments in the same period.
The full vitality of the 5G mobile phone consumer market has spawned consumers' more frequent participation in online application scenarios such as audio-visual entertainment, online games, and virtual events. In order to respond to diversified market application trends with high-performance hardware devices, local mobile phone manufacturers focus on supporting the research and development of high-end mobile phone product lines for 5G networks, with innovative selling points of smartphones such as "light and thin models" and "folding screens", which are Consumers bring a more comfortable smartphone experience to the senses. At the same time, how to create products that support smoother mobile phone connection technology and comply with specifications also brings new issues to the development of smart phones.
As the core accessories for triggering the intelligent response of the device, the sensor assists the consumer electronic device to continuously ensure a sensitive and accurate intelligent response in various environments. At the same time, due to the comprehensive penetration of mobile phones in daily life scenarios, high frequency of use and long use time, sensors can effectively control the power consumption of the device, help improve the use time of the device, and help prolong the life of the product. Semtech's PerSe™ smart sensor platform can help smartphone manufacturers provide high-quality connectivity in 5G/Wi-Fi 6, improve the RF performance of smartphones, and ensure that products meet SAR (specific absorption rate) specifications. PerSe's superior sensing performance and strong anti-noise capability allow manufacturers to design devices with longer detection distances in a smaller area, helping manufacturers to bring consumers a more extreme smartphone experience.
Optimize connection performance for smooth device interconnection
A smooth network connection is the premise to ensure an excellent user experience of smartphones. Especially in the 5G era, consumers expect smartphones to bring faster and smoother device performance. By incorporating sensors, it can help phone manufacturers improve the connectivity of their devices. Taking PerSe Connect as an example, by integrating the product into smartphones that support wireless protocols such as 5G sub-6 GHz, 4G and Wi-Fi 6, the RF power can be optimized for the best connection performance, even when watching videos at high altitudes. A smooth user experience can also be guaranteed in traffic application scenarios. PerSe Connect Pro is the first sensor product that can provide ultra-high sensing performance for high-band 5G mmWave devices in smartphones, laptops and tablets. At the same time, the compliance of 5G high-band connections is guaranteed.
Intelligent temperature compensation to reduce extra power consumption of equipment
As the use frequency of mobile phones continues to rise in life, how to optimize the standby time is also one of the hot topics that the market is concerned about. In addition to its own advantages such as small size and ultra-low power, PerSe can intelligently identify the human body and non-living objects, and improve the response effect of the device while ensuring that the mobile phone device has high anti-interference ability. In addition, PerSe's advanced temperature compensation function minimizes false triggering of smartphone devices, thereby helping devices reduce additional power consumption and achieve longer battery life.
Compliant with SAR specifications, bringing peace of mind
According to statistics, Chinese users spend an average of 3.3 hours a day on their mobile phones. As an electronic device that is in close contact with the human body for a long time, smartphones are bound to meet strict product compliance standards to ensure that consumers can use them with peace of mind. The SAR value, the Specific Absorption Rate, refers to the electromagnetic wave absorption ratio or specific absorption rate. SAR value is an important parameter to measure the compliance of electronic products, and it is also one of the necessary compliance standards for daily consumer electronic products.
At present, smartphones require 5G networks to support higher bandwidth and information transmission volume for the best user experience. To achieve these performance levels, 5G smartphones are designed with more antennas. Semtech's PerSe smart sensor product line, with its outstanding sensitivity, enables optimal human presence detection, enabling smartphone manufacturers to enhance connectivity while ensuring product compliance with SAR specifications. With the blessing of PerSe, when consumers use their mobile phones to talk or browse social media, smartphones can detect the proximity of the human body, automatically adjust and optimize the radio frequency (RF) radiation intensity of the device, ensuring peace of mind for consumers. experience.
Through more than ten years of continuous exploration and innovation, Semtech sensor technology has been in a leading position in the market. PerSe smart sensors can provide the ultimate connection performance and automated user experience for smartphones, while complying with SAR specifications, helping customers to improve product advantages and bring broader market opportunities.
