5 key technologies of Wi-Fi 6:
1. Orthogonal frequency-division multiple access (OFDMA)
Rather than orthogonal frequency-division multiplexing (OFDM) used by Wi-Fi 5, Wi-Fi 6 uses the more advanced, multi-user oriented OFDMA. OFDMA enables more users to simultaneously operate on the same channel, improving efficiency, latency, and data throughput.
2. Target wake time (TWT)
Target wake time allows devices to be smarter about how often they “wake up” to send or receive data. TWT enables devices to use sleep time more effectively, conserving battery life, and making IoT networks more power-efficient.
3. 1024 quadrature amplitude modulation mode (1024-QAM)
A higher modulation scheme means higher data throughput and capacity. Combined with other key technologies, moving from 256-QAM (Wi-Fi 5) to 1024-QAM (Wi-Fi 6) results in a 25% increase in capacity.
4. Transmit beamforming
This capability improves signal power, resulting in higher data rates in a given range, which is crucial to achieving high speeds when operating in a higher spectrum range.
5. Multi-user multiple-input, multiple-output (MU-MIMO)
MU-MIMO enables an access point to handle a larger number of simultaneous users by increasing the data transfer rate. In addition, it also adds an uplink capability for multiple users.
