Nissan Motor Co., Ltd. discloses a lane change assist system "Side Collision Prevention System" (SCP) for detecting a vehicle approaching obliquely behind. The system can detect vehicles approaching from the rear side through the 24 GHz radar to prevent rear-end collisions with the rear vehicles when the lane changes. In terms of the detection range of the sensor, the lateral direction is about 3 meters and the rear is about several meters. The system is currently under development and is scheduled to enter the practical phase from 2010 to 2011. This article refers to the address: http:// In the disclosed system, the 24 GHz radar is built into the left and right sides of the rear bumper. When the radar detects the vehicle at the corner of the driver's line of sight, the warning light at the bottom of the front pillar lights up to draw the driver's attention. After the indicator light is on, if the driver wants to turn the steering wheel and change the lane, the system will remind the driver by sound and prompt light. In addition, the system distributes the braking force to each wheel through an anti-slip device (ESC), and generates a yaw moment in the opposite direction of the lane change. However, this yaw moment is small and the driver can still change the lane by turning the steering wheel. The sensor is likely to use a 24 GHz radar, and which component manufacturer's product will eventually be used is still under discussion. At present, with the European automobile manufacturers as the center, the lane change assisting system that detects the approaching vehicle behind the slope has entered the practical stage one after another, and when the vehicle approaches the vehicle behind the slope, the linkage use of the prompt system and the vehicle control system has become a new trend. German BMW plans to install a system that vibrates the steering wheel to change the driver's attention when changing lanes in the new "7 Series", which was launched in Europe at the end of 2008. Nissan uses the linkage with the ESC to alert the driver when changing lanes. This is different from BMW.

Figure 2: The lane change can be safely performed because the approaching vehicle at the corner of the driver's line of sight can be detected.

The indicator light illuminates when there is an approaching vehicle. An Indoor Access Point is a device for wireless local area networks (WLAN) that provides wireless network coverage and connectivity. It can connect to a wired network and transmit data via a wireless signal, allowing users to connect to the network wirelessly within coverage.

Indoor access points come in a variety of different types and specifications to suit different scenarios and needs. Here are some common types of indoor access points:
1. Single Band Access Point: A single band access point operates in the 2.4GHz band and typically provides a maximum transfer rate of 300Mbps. This type of access point is suitable for small office or home networks because the 2.4GHz band has better penetration and coverage, but a relatively low transfer rate.
2. Dual Band Access Point: The dual band access point supports both 2.4GHz and 5GHz bands, providing higher transmission rates and better performance. The 5GHz band has more interference free channels than the 2.4GHz band, which can provide faster speeds and more stable connections. Dual-frequency access points are suitable for medium sized offices, malls or hotels.
3. Lightweight Access Point: A lightweight access point is a wireless network device that needs to be used with a network controller. Lightweight access points do not have independent management functions themselves, but are centrally managed and configured via a network controller. This type of access point is suitable for large enterprises or organizations to enable centralized management and monitoring of the entire network.
4. Standalone Access Point: A standalone access point is a standalone device that has its own management and configuration functions and does not require additional network controllers. This type of access point is suitable for small businesses or individual users and can provide a simple and easy-to-use wireless networking solution.
5. Scalable Access Point: A scalable access point is a device that can scale on demand, increasing or decreasing the number of access points based on network demand. This type of access point is suitable for places that require flexible scaling, such as large office buildings, schools, or hospitals.
In addition to the types listed above, there are some special purpose indoor access points, such as:
1. Wall-mounted Access Point: A wall-mounted access point can be plugged directly into a Wall power outlet without the need for an additional power cord. This type of access point is suitable for home networks or small offices and can provide easy installation and use.
2. Integrated Antenna Access Point: The antenna of the antenna access point is integrated into the device, and no additional antenna installation is required. This type of access point is suitable for sites that require simple installation and a nice look.
3. Multiple Antenna Access Point: Multiple antenna access points can achieve better signal coverage and performance through multiple antennas. This type of access point is suitable for large venues or high-density user environments, such as conference rooms, stadiums or airports.
To sum up, there are many different types and specifications of indoor access points, which can be selected according to different scenarios and needs. Whether it's a small office, home network or a large enterprise, you can achieve convenient wireless network coverage and connectivity through indoor access points.
