Near field communication, leading a new era of Internet of Everything

Through the multi-screen collaboration function, the mobile phone can be projected on the smart screen at home with one key, and the "small screen" instantly becomes "big screen"; the music played on the mobile phone will automatically continue to be played in the car when entering the car, and the user experience will not be interrupted , No need to switch manually; file transfer between devices no longer requires a data cable, easy to complete with one finger... With the rapid development of technology, our lives are becoming more intelligent and convenient day by day. Through a small mobile phone, we are entering a new era of Internet of Everything.

Near-field communication is a vital link in the era of Internet of Everything. According to statistics, it is estimated that by 2025, the shipment of short-range communication equipment will reach 6 billion, with a compound annual growth rate of 10%, which will give birth to countless new equipment, new scenarios, and new opportunities. Near-field devices can communicate through a variety of technologies, the most common ones are Bluetooth, WiFi P2P, etc.

In order to allow developers to use the short-distance communication capabilities more conveniently and quickly, Huawei HMS Core launched Nearby Service short-distance communication service , which provides your applications with powerful functions such as short-distance data transmission, message subscription, and WIFI configuration sharing. Create more ways to play.

Easy to find

For users, discovery speed is the first ring of user experience. The discovery speed between devices determines whether the first pairing process is sensitive and whether the user experience is smooth. With the support of Huawei’s self-developed agreement, the use of Nearby Service can greatly increase the node discovery rate, which is less than 3s in the Bluetooth scenario and less than 300ms in the Wi-Fi scenario. Lay the foundation for business.
In the short-distance social scene, Nearby Service helps instant messaging apps and dating apps to quickly discover people around them, enabling scenarios such as adding friends, face-to-face group building, and discovering when approaching, and exiting when leaving, creating a smooth user experience.

High-speed transmission

Secondly, the transmission speed determines the "ceiling" of the use scene. In the past, the transmission speed of Bluetooth was only tens of KB/s, and it took a long time to transmit an MP3 song, and the user experience was poor. Now, with the latest Bluetooth protocol and Huawei's self-developed algorithm, the Nearby Service transmission bandwidth of up to 60MBps, which greatly expands the application scenarios of face-to-face data transmission. With the support of large bandwidth, we can not only share documents, music, photos in an instant, but also share large files such as movies and games with our friends. There is no need for Internet transfer, no network traffic overhead, and more new ways of social entertainment. .

Precise positioning

Not only that, in scenarios such as offline search, indoor navigation, etc., users have a huge demand for accurate range and angle measurement functions. For example, you often cannot find the key when you go out. If the key integrates Bluetooth or ultrasonic ranging related hardware, and then cooperates with the supported APP, you can quickly meet the user's need for precise search and improve the user experience. In the near future, Nearby Service will launch a range and angle measurement feature based on ultrasonic and Bluetooth to achieve accurate measurement within 10 meters between multiple devices, providing application developers with richer near-field communication functions.

Facing the new era of Internet of Everything, HMS Core is actively creating an open and win-win ecological environment. Nearby Service can not only be used on Huawei's terminal equipment, but also supports all Android platforms and Windows operating systems. We hope that through Huawei’s “1+8+N” full-scenario smart ecology, more and more smart devices, more and more abundant near-field interactions, and more and more business growth opportunities will emerge. We look forward to working with all developers to build a smart Internet of Everything ecosystem to make life smarter and better!

On October 23, the Huawei Developer Conference HMS Core 6.0: Connection and Communication Forum will introduce Huawei's multiple solutions in the field of connection and communication, and invite people from Douyin, Xishanju, Beidou Application Research Institute, and Ailian Technology And other partners, to share mobile application development practical experience and solutions for developers, and look forward to exploring the value of connection with developers.
