In the current Chinese market, although the deployment rate of automotive active safety systems is still low (according to statistics, the average active safety deployment rate of each car in China is 1.7 times lower than the global average), but in recent years, the development of active safety systems has been rapid The market potential is huge, and the development trend is to penetrate parking assistance systems and TPMS first, and other active safety devices will gradually penetrate, but will be first applied to high-end models. At present, a considerable number of cars in the Chinese market are equipped with ABS and ESP (less than 20%). In the future, they will continue to catch up with the global average car deployment rate.
For semiconductor companies, to develop the automotive active safety market, the key challenge is to maintain compliance with customer expectations for quality levels while responding to new safety standards (ASIL, ISO26262). In addition to the strict requirements of the existing AEC-Q100 certification process, the industry now requires compliance with a new standard, the functional safety standard ISO26262, which was developed by original equipment manufacturers (OEMs) and Tier 1 car manufacturers. Now this standard has been pushed to the development and practice at the chip level. This is a consensus process initiated by first-tier auto manufacturers and their semiconductor suppliers, and there are currently no defined standards. It requires the designation of safety managers within the R & D team and training to expedite the team ’s understanding of these requirements. Among them, the responsibility of semiconductor devices is crucial, because they will be integrated into safety-critical applications, such as airbags, power steering, and power braking systems.
In this process, basically, the integration of semiconductor technology makes more and more functions simplified, providing designers with convenience. For example, in motor applications (more and more motors are used in automobiles), there is no longer just a simple driver chip to power and power off the motor, but a one with some written memory or status Chips (integrated circuits) with advanced instructions in the machine. The advantage this brings to the designer is to simplify the application firmware, so that the designer only has to take into account the instructions of the application and not the motor instructions. This can reduce some source code, and correspondingly reduce the memory footprint, significantly reducing the load of the microcontroller when processing certain time-critical tasks.
In the automotive field, ON Semiconductor focuses on certain application areas (such as: audio DSP, tuner, LCD driver, pump drive, electric power steering EPS, lighting, door, parking assist, and car air conditioning, etc.), and develops related knowledge Property rights (IP) and products, provide customers with appropriate silicon chips to meet customer needs. Especially for automotive active safety technology, ON Semiconductor actively responds to the new needs of dynamic braking, indirect tire pressure monitoring, night vision and parking assist applications, and has produced a variety of devices for these applications. At the same time, ON Semiconductor Has expertise in motor drive and is recognized as a leading supplier of stepper motor drivers.
It is worth noting that, because the active safety of the car is obviously a technology that fully utilizes the sensor signals around the body, there are many sensors in the car today, so these signals need to be reused to assist the driver in making decisions. The important trend of sensor fusion is to fully utilize the accelerometer signals of the airbag system, steering wheel position, ESP gyroscope information, and radar signals that reveal the location of obstacles to provide decisions that are beneficial to the brake ECU. Information, the brake function is activated at a faster speed than the driver, which also requires that certain automotive electronic functions can be controlled by wire.
The WiFi 6 Ceiling Wireless AP is a ceiling wireless access point based on the WiFi 6 (802.11ax) standard. It is a device designed to provide wireless Internet connectivity and can be mounted on the ceiling of a building to provide users with high-speed, stable wireless Internet coverage.
WiFi 6 Ceiling Wireless AP offers a number of advantages over previous WiFi standards such as WiFi 5, or 802.11ac. The benefits of WiFi 6 Ceiling Wireless aps and how they affect users are described in detail below.
1. Higher speed and capacity:
WiFi 6 Ceiling Wireless AP uses OFDMA technology (orthogonal frequency division multiple access), which can divide the wireless channel into multiple sub-channels, each sub-channel can transmit multiple data streams at the same time, improving the capacity and efficiency of the network. This means that the WiFi 6 Ceiling Wireless AP can deliver higher speeds and more stable connections to more devices at the same time with the same spectrum resources. For high-density environments, such as office buildings, conference rooms, or large event venues, WiFi 6 Ceiling Wireless AP can better meet users' needs for high-speed networks.
2. Low latency:
The WiFi 6 Ceiling Wireless AP uses Target Wake Time (TWT) technology to put devices to sleep at a predetermined time, reducing communication latency between devices. This is important for real-time applications such as video conferencing, online gaming, and iot devices. A low-latency network can provide a better user experience and support more real-time applications.
3. Better coverage:
The WiFi 6 Ceiling Wireless AP uses higher antenna gain and more advanced beamforming technology to provide wider coverage. This means that in the same environment, the WiFi 6 Ceiling Wireless AP can provide a more stable, longer distance wireless signal, reducing signal attenuation and interference, and improving network reliability and coverage.
4. Better power management:
The WiFi 6 Ceiling Wireless AP uses Target Wake Time (TWT) technology to put the device to sleep for a predetermined amount of time, reducing the power consumption of the device. This is important for battery-powered devices such as smartphones, tablets, and iot devices. Better power management can extend the battery life of the device and reduce frequent charging of the battery.
5. Better security:
WiFi 6 Ceiling Wireless AP uses stronger Encryption algorithms and authentication mechanisms, such as WPA3 encryption and Opportunistic Wireless Encryption (OWE) authentication, to provide better security protection. This is important to protect users' personal information and network data. The WiFi 6 Ceiling Wireless AP also supports more user isolation and guest management features to better protect the network.
In summary, the WiFi 6 Ceiling Wireless AP offers higher speed and capacity, lower latency, better coverage, better power management, and better security than previous WiFi standards. These advantages can provide a better user experience and meet the needs of users for high-speed, stable and secure wireless networks. Whether in the home, office or public space, WiFi 6 Ceiling Wireless AP is an ideal wireless access solution.
