From GreenTooth to StarFlash, wireless communication achieves transcendence Like Bluetooth and Wi-Fi, StarFlash is also a short-range wireless communication technology. To understand it, one must first understand Bluetooth and Wi-Fi, two communication technologies that play important roles in our lives. Although their application scenarios are similar, the focus of the two technologies is different: Bluetooth pursues lower power consumption, while Wi-Fi pursues higher transmission rates. Over the past 20 years, both technologies have developed along their respective goals, establishing extensive ecosystems and application scenarios, and also erecting high technological barriers. In 2019, Huawei, in collaboration with academia and industry, jointly developed a more perfect short-range wireless communication technology and initiated the establishment of the "GreenTo...

In today's digital era, wireless connectivity has become an indispensable part of our daily lives and work. However, understanding the characteristics and advantages and disadvantages of different frequency bands is crucial when choosing the most suitable wireless connection for your needs. This article will explore the 2.4 GHz, 5 GHz, and the latest 6 GHz frequency bands to help you make informed choices. Understanding the characteristics of different frequency bands: 1.    2.4 GHz Band:Wave Length and Frequency Characteristics: The 2.4 GHz band has relatively longer wavelengths and lower frequencies, thus offering a longer transmission range but relatively slower speeds.Application Scenarios: Due to its good penetration capability and transmission range, the 2.4 GHz band is often used for transmitting small amounts of data over longer distances, such as remo...

In today's digital age, Wi-Fi has become an indispensable part of our lives, but the evolution of this wireless communication technology has been a fascinating and rich journey. From its humble beginnings with the first steps taken, to the high-speed data transmission of Wi-Fi 7 today, each birth of a Wi-Fi standard has been accompanied by numerous innovations and technological breakthroughs. 802.11: The earliest Wi-Fi standard, released in 1997, supporting a maximum transmission rate of 2Mbps. This standard operated in the 2.4 GHz frequency band and employed Frequency-Shift Keying (FSK) and Quadrature Phase Shift Keying (QPSK) modulation techniques. 802.11a: Released in 1999, it introduced the 5 GHz frequency band for the first time, offering higher transmission rates of up to 54 Mbps. Using Orthogonal Frequency Division Multiplexing (OFDM) tech...

Background On November 4, 2022, Huawei's newly established StarFlash Alliance, which has been in existence for nearly two years, unveiled its own communication standard—StarFlash Wireless Short-Range  Communication 1.0, leading a new trend in the wireless communication field. This standard includes two modes: basic access and low-power access, providing devices with flexible and diverse connection methods. The flexible channel design allows StarFlash to operate in extremely low-power modes according to the actual needs of the device, improving the battery life of small wireless devices or reducing their size. On August 4, 2023, Huawei shook the HDC conference by unveiling a new generation of short-range wireless connectivity technology: StarFlash NearLink. The birth of this technology stems from endless exploration and innovation in the era of ubiquitous con...
