Wi-Fi 6 | Notion

formerly known as 802.11ax is one of the largest leaps in Wi-Fi technology since its introduction.

Wi-Fi 6 is faster and more efficient for networks with a larger number of connected devices

Higher data rates: Band splitting or increased client group sizes allow for uploading and downloading greater amounts of data.
Increased band capacity: Band utilization increased from 80 mHz to 160mHz, creating a faster connection from the router to connected devices.
Better performance: The input/output streams are doubled from the 4 by 4 allowed by Wi-Fi 5, to 8 by 8 in Wi-Fi 6, allowing more clients to be grouped
Improved power efficiency: devices only connect to the network when sending or receiving data, increasing battery life

Capabilities of Wi-Fi 6

Channel sharing for better efficiency and shortens the time it takes to send data once a user gives the send command.
Target Wake Time (TWT) improves the network speed and increases battery life by allowing battery-powered devices to sleep when not in use.
Multi-user MIMO (Multiple Input, Multiple Output) wireless technology allows more data to be transferred simultaneously. This ability increases capacity and efficiency in high bandwidth applications like voice calls or video streaming.
160MHz channel utilization gives more space for transmitted data and increases bandwidth capability
1024 quadrature amplitude modulation combines two signals into a single channel, so more data is encoded
Orthogonal Frequency Division Multiple Access(OFDMA) allows for bandwidth splitting, which is assigned dynamically by the access point to separate devices.
Transmit beamforming is a technique that sends signals that allows for more efficient higher data rates by targeting each connected device.
