Quartz crystal oscillator, application in new generation wireless network Wi-Fi 6

Wi-Fi is an indispensable role in today's life. Whether it is in public places such as homes, offices, hotels, cafes, etc., every time you go to a new place, you will be asked the same question: "What is the Wi-Fi password?" ” Wi-Fi has completely penetrated into people’s lives.

Wi-Fi is a wireless LAN technology, also called wireless network technology, that uses radio waves for communication and can be used to connect networks and the Internet. Wi-Fi technology is a wireless network technology based on the IEEE 802.11 standard. It allows devices to be interconnected through wireless signals to share files and other resources, and implement Internet access and other Internet applications.

1. Wi-Fi Development History

Wi-Fi has undergone many iterative updates since 1997, as follows:

Due to the complexity of the original naming, the 802.11a naming format that has been used since 1997 has officially withdrawn from the stage of history. The naming was officially updated in 2019 as follows:

Wi-Fi 6 (full name: 802.11ax WLAN) is a generation of Wi-Fi wireless network standards. Compared with previous standards, it has great improvements in speed, capacity, data transmission distance, stability and security. This means Wi-Fi 6 is better suited to the needs of modern networks than earlier Wi-Fi standards, including supporting more devices online at the same time, higher speeds and less interference. Currently, more and more devices support Wi-Fi 6 technology, including smartphones, tablets, laptops and routers.

2. Wi-Fi 6 new technology

Advantages of Wi-Fi 6:

Higher speed : Wi-Fi 6 can greatly improve the transmission speed of wireless networks, with a theoretical speed of 9.6 Gbps, which is nearly 4 times faster than Wi-Fi 5.

More device support : Wi-Fi 6 has higher device density, supports more devices to connect to wireless networks at the same time, and can easily meet the connection needs of a large number of devices in homes, companies, schools and other places.

Longer coverage distance : Wi-Fi 6 adopts a better signal transmission mechanism, which makes the transmission distance of wireless signals longer and has a stronger ability to transmit through obstacles (such as walls, doors, glass, etc.), reducing Signal dead zone.

Higher security : Wi-Fi 6 uses stronger encryption technology WPA3, which can better protect network security and ensure data confidentiality and integrity.

Lower energy consumption : Wi-Fi 6 adopts more intelligent power control technology and power-saving technology, allowing devices to save more power when connected to Wi-Fi networks and extending the life of the device battery.

3. Wi-Fi 6 chip

A new round of competition surrounding Wi-Fi 6 chips is underway. Judging from the current market situation, Wi-Fi 6 chips are mainly divided into IoT Wi-Fi 6 chips and router Wi-Fi 6 chips.

From the perspective of the global market, Qualcomm, Broadcom and Marvell have all launched related products for the Wi-Fi 6 chips required by the router market. In Taiwan, MediaTek and Realtek's router Wi-Fi 6 chips have gained market recognition. There are not many players in mainland China working on Wi-Fi 6 chips for routers. Huawei, SiChang Communications, and Langli Semiconductor are mainly committed to the development of this field.

4. Application of quartz crystal oscillator in Wi-Fi 6

In Wi-Fi 6 technology, the crystal oscillator mainly plays the role of clock signal source. The crystal oscillator provides a precise clock signal for use by various circuits in the Wi-Fi 6 system, ensuring that the frequency and timing of these circuits can be well controlled and synchronized. The high-speed transmission of Wi-Fi 6 technology requires stricter clock synchronization than before, so the quality and accuracy of the crystal oscillator play a crucial role in the performance and stability of the system.

HCI provides technology and different solutions for different chip solutions. For passive quartz crystal oscillators, it conducts matching tests with original chips and has been verified and recognized by customers. It also ships in large quantities to related routers and IoT-related customers.

5. Application prospects of Wi-Fi 6

It is expected that by 2023, the demand for Wi-Fi 6 will gradually grow with the popularity of devices. According to data from some analytical institutions, the number of Wi-Fi 6 devices worldwide will exceed 1.4 billion by 2023, and this number is still increasing. Moreover, more and more new smart devices will support Wi-Fi 6 technology, such as smartphones, smart TVs, smart speakers, laptops, digital cameras, game consoles, etc. These devices all require higher-speed and more stable Wi-Fi. Fi connection to provide better user experience and better data transfer. Therefore, the demand for Wi-Fi 6 will continue to grow in the next few years and become the mainstream technology in the wireless network market.
