802.11ax Powerful Performance

1.The 5GHz band of 802.11ax is 1.37 times faster than 802.11ac.
2.The 2.4GHz band of 802.11ax is 1.91 times faster than 802.11n.
3. In DBDC (dual-band, dual-concurrent) mode, 802.11ax with both 5GHz+2.4GHz is 1.52 times faster than the combination of 5GHz 802.11ac + 2.4GHz 802.11n


OFDMA is applied in Wi-Fi 6 (IEEE 802.11ax). It is a user access technology that allows spectrum to be simultaneously allocated to multiple users or devices, enabling the transmission of multiple data streams on the same frequency band, thereby enhancing network efficiency. 

  It can also be adjusted according to demand or priority, achieving more flexible network resource management. By dividing the spectrum into small subcarriers, OFDMA can also reduce interference between adjacent users, making the signal more reliable and stable. This is one of the latest key technologies in Wi-Fi 6.


Downlink & Uplink MU-MIMO

  In 802.11ac, basic Downlink MU-MIMO was introduced, allowing wireless access points (such as routers) to simultaneously transmit data to multiple client devices.

  However, in Wi-Fi 6, MU-MIMO technology has been further developed to communicate simultaneously with multiple devices in both the Downlink and Uplink directions.

  This means that whether sending data from the access point to devices or from devices to the access point, multiple device data streams can be processed simultaneously.

  This enables faster and more reliable wireless connections, while also improving network throughput and efficiency.

BSS Coloring

  BSS Coloring is a feature introduced in the 802.11ax Wi-Fi standard, which helps reduce interference from neighboring Access Points (APs) and improves coexistence between multiple APs.

  The basic idea behind BSS Coloring is that each BSS or AP is assigned a unique color, which is added to the preamble of each transmitted data packet. When a client device receives a packet, it can check the color of the received preamble and use this information to differentiate signals from different APs.

  BSS Coloring helps prevent unnecessary retransmissions and conflicts caused by neighboring networks, thereby improving overall network efficiency and potentially extending the available range of IoT devices.

802.11r Fast Roaming Technology

•IEEE 802.11r (Fast Basic Service Set Transition) is a wireless network standard aimed at achieving fast roaming without the need for complete re-authentication.
•Fast Roaming: 802.11r allows mobile devices to transition faster from one access point (AP) to another AP without the need for complete re-authentication and connection processes.
•Seamless Switching: By reducing the need for re-authentication, 802.11r achieves a seamless roaming experience. Users can naturally switch to access points with stronger signals or better quality while moving, without the need to manually reconnect to the network or input credentials again.
•Pre-authentication: Before actual movement occurs, mobile devices can pre-authenticate to potential target APs, enabling quick switching to the AP when needed, further reducing connection interruption time during the switching process.
