What are the six advantages of Wi-Fi 6 in the car?
NXP and industry leaders, including the IEEE 802.11ax working group, have made several important updates and added features for Wi-Fi 6. There are six main reasons why automakers use Wi-Fi 6 in the development of existing platforms.
1. Reduce blocking
In recent years, as more vehicles (most vehicles are expected to include at least one Wi-Fi device by 2022) provide Wi-Fi functionality, the use of Wi-Fi has increased significantly. This leads to increased blockage and interference inside and outside the car. This congestion will affect wireless performance on roads, in traffic jams, in parking lots, and even in dealer parking lots.
Wi-Fi 6 increases the total available bandwidth, reduces congestion through two functions, quadruples the bandwidth, and increases the total bandwidth of each user. OFDMA (Orthogonal Frequency Division Multiple Access) allows multiple users with different bandwidth requirements to access the channel simultaneously. BSS (Basic Service Set) coloring allows Wi-Fi 6 to identify signals from different radio systems on the same channel. The device can then identify and ignore unnecessary traffic and increase the total available bandwidth.
2. Faster
In addition to the optimized performance described, Wi-Fi 6 can indeed achieve faster data transfer rates. In extremely crowded environments, the peak data transmission rate of a single client device can also be increased by 40%. Take full advantage of several optimization and addition functions of the basic protocol, including OFDM, MU-MIMO and 1024-QAM (quadrature amplitude modulation), to increase throughput.
3. Reduce power consumption
Accessing the Wi-Fi network when the flame is turned off will waste precious battery power and shorten the parking time of the car. This limits Wi-Fi utilization while parking. Depots use a variety of technologies to reduce system power consumption and reduce current consumption during flameout. Wi-Fi 6 makes this process easier.
Wi-Fi 6 uses a more efficient planning mechanism called the target wake-up time (TWT), which allows the access point to plan the wake-up time of each client. The car can sleep for a set period of time, and then wake up when Wi-Fi is needed. For example, on the dealer's premises, the car can receive the necessary updates, ready to start and run normally at any time, even if it is parked for a long time.
4. Increase coverage
When a car is parked in a home garage, dealer site, or parking lot, most vehicles are far away from the nearest access point. This makes it difficult to use Wi-Fi functions such as wireless firmware updates or vehicle data upload.
Wi-Fi 6 adds several core technologies, greatly improving coverage. At present, 2.4 Ghz broadband is usually used to maximize the communication distance with longer wavelengths. Wi-Fi 6 adds a dedicated range extension mode to further extend this distance. Wi-Fi 6 can also support up to 8 antennas in the access point, of which 8x8 sound feedback can achieve full download performance over a longer distance.
5. Upload performance
As cars become more intelligent and autonomous driving modes are introduced, the data generated in cars is growing exponentially. In addition, in order to monitor passengers or drivers in carpooling and other programs, car cameras are increasing. In the near future, sharing this data requires upload performance and download speeds to be comparable.
To complement the download multi-user MIMO (MU-MIMO) introduced in Wi-Fi 5, Wi-Fi 6 enhanced the upload function. For multi-user networks, the upload data rate will increase by as much as 80%.
6. Consumer satisfaction
Strictly speaking, the consumer experience is not a feature of Wi-Fi 6, but the use of Wi-Fi 6 in vehicles helps to improve the driving experience and meet consumer demand for technology. Wi-Fi 6 already has a place in consumer devices, including smartphones and access points, and will quickly become a part of the Internet of Things and smart home devices. Consumers want their vehicles to incorporate this trend, and with the increasing popularity of Wi-Fi 6, a more reliable and seamless connection will be obtained.
Without further ado
There is no delay in incorporating Wi-Fi 6 into the design. The standard technology on smartphones usually takes two to three years to be applied to vehicles. Consumers want their cars to keep up with these trends, especially with regard to experience, performance and quality. For this reason, many car manufacturers have incorporated Wi-Fi 6 into the next-generation vehicle development plan.
