Understanding 802.11 ax Streams
In Wi-Fi 6, a stream refers to a single flow of data between a device and an access point. The number of streams supported by a Wi-Fi 6 device depends on the device’s capabilities and the environment in which it is operating. A single 802.11 ax stream can support a maximum data transfer rate of 1.2 Gbps using 1024-QAM and a 160 MHz channel bandwidth. However, this rate can be affected by various factors, including the device’s capabilities, the environment, and the level of interference.
Factors Affecting the Maximum Speed of a Single 802.11 ax Stream
The maximum speed of a single 802.11 ax stream is affected by several factors, including:
Channel Bandwidth
The channel bandwidth refers to the amount of spectrum allocated to a single channel. In Wi-Fi 6, the channel bandwidth can range from 20 MHz to 160 MHz. A wider channel bandwidth can support faster data transfer rates, but it also increases the risk of interference.

The modulation and coding scheme (MCS) refers to the method used to encode and modulate the data. In Wi-Fi 6, the MCS can range from BPSK (binary phase-shift keying) to 1024-QAM. A higher-order MCS can support faster data transfer rates, but it also requires a higher signal-to-noise ratio (SNR).
Number of Spatial Streams
The number of spatial streams refers to the number of independent data streams that can be transmitted simultaneously. In Wi-Fi 6, the number of spatial streams can range from 1 to 8. A higher number of spatial streams can support faster data transfer rates, but it also requires more complex hardware and a higher SNR.
Interference and Noise
Interference and noise can significantly affect the maximum speed of a single 802.11 ax stream. Interference can come from other wireless devices, microwave ovens, and other sources of electromagnetic radiation. Noise can come from the device itself, the environment, and other sources of electromagnetic radiation.

Furthermore, the quality of the Wi-Fi 6 hardware and software, as well as the design of the network, can all impact the actual speeds achieved in real-world scenarios.
How does OFDMA improve the performance of Wi-Fi 6 networks?
OFDMA is a key technology in Wi-Fi 6 that improves the performance of networks by allowing multiple devices to share the same channel. This is achieved by dividing the channel into smaller sub-channels, each of which can be allocated to a specific device. This approach enables multiple devices to transmit data simultaneously, reducing congestion and improving overall network efficiency. OFDMA also enables the access point to schedule transmissions from multiple devices, ensuring that each device gets a fair share of airtime and reducing the likelihood of collisions.
The benefits of OFDMA are particularly noticeable in environments with a large number of devices, such as smart homes, businesses, and public venues. By allowing multiple devices to share the same channel, OFDMA reduces the need for devices to compete for airtime, which can lead to congestion and reduced network performance. Additionally, OFDMA enables the access point to prioritize traffic from certain devices, ensuring that critical applications such as video streaming and online gaming receive the necessary bandwidth and low latency. This makes OFDMA a key feature of Wi-Fi 6, enabling networks to support a growing number of devices and applications.
What is the difference between Wi-Fi 6 and Wi-Fi 5, and is it worth upgrading to Wi-Fi 6?
