WIFI 6 and Bluetooth 5.2
The transmission rate of WiFi6 can theoretically reach a maximum of 9.6Gbps, which is nearly three times higher than the maximum transmission rate of the previous generation WiFi5 of 3.5Gbps. This means that under the new standard, whether you are streaming 4K high-definition videos or downloading files and applications, you will no longer experience the feeling of lag.
WiFi6 uses the latest OFDMA technology, which can support multiple terminals transmitting in parallel at the same time.
WIFI6 has the following advantages:
1.BSS coloring anti-interference mechanism. The purpose of this technology is to increase the system capacity of wireless networks in dense environments and increase frequency reuse between BSSs. This enables the receiving end to identify co-channel interference signals early and refuse to receive them, saving sending and receiving time and avoiding mutual interference between neighboring networks.
2. Save computer battery power. WiFi6 introduces Target Wake Time (TWT, target wake time) technology. The wireless router will only connect when receiving a transmission command, and remain asleep at other times. It is estimated that power consumption can be reduced by 30% and battery life is also expected to be extended.
3.WiFi6 is more secure. WiFi6 devices adopt the new generation encryption security protocol WPA3 protocol and have passed WiFi Alliance certification. This prevents brute force attacks, etc., and security is further guaranteed.
4. Compatible with 2.4GHz frequency band. Compared with the 5GHz frequency band, the 2.4GHz frequency band has stronger penetration ability, less signal loss, and longer propagation distance. In an environment with a large space and many obstacles, if there are no particularly high requirements for network speed, use 2.4 The GHz band may have a better experience than 5GHz.
Compared with previous versions, Bluetooth 5.2 has more advanced technology and better performance, and can provide better support for wireless communication between various smart devices.
Bluetooth 5.2 has the following improvements:
1. Support faster data transmission rates: Bluetooth 5.2 adopts a more efficient broadcast communication method, which can achieve faster data transmission rates;
2. Provide better security: Bluetooth 5.2 adopts a more secure random address generation algorithm, which can prevent tracking and identification attacks;
3. Support more connected devices: Bluetooth 5.2 can establish connections with up to 125 BLE slave devices at the same time, which has better applicability in some special scenarios;
4. Introducing new features: Bluetooth 5.2 adds new features such as LE Power Control and LE Isochronous Channels, making it better applicable and performant in some emerging fields and application scenarios;
In general, Bluetooth 5.2 has more advanced technology and better performance than previous versions, and can provide better support for wireless communications between various smart devices.
