Is WiFi 6 better or WiFi 6E?

WiFi 6, also known as 802.11ax, builds on 802.11ac technology with the following upgrades:

Faster theoretical maximum speeds

  • WiFi 5 (802.11ac) maximum speed: 3 Gbps
  • WiFi 6 maximum speed: 9.6 Gbps

This 4x increase is achieved through more efficient data encoding and modulation techniques. Real-world speeds will depend on your internet connection and devices.

Increased number of simultaneous connections

WiFi 6 uses MU-MIMO (multi-user, multiple input, multiple output) technology to allow more devices to connect and transmit data simultaneously. Where WiFi 5 supports 4×4 MU-MIMO (4 devices concurrently), WiFi 6 supports 8×8 MU-MIMO (8 devices concurrently).

This helps reduce network congestion in busy environments with many connected devices.

Improved efficiency with OFDMA

WiFi 6 introduces OFDMA (orthogonal frequency-division multiple access), allowing data transmissions to be divided into smaller sub-carriers. This allows more devices to share the available bandwidth efficiently.

With WiFi 5, only one device could transmit at a time. OFDMA enables multiple devices to transmit simultaneously, reducing latency.

Better performance in dense, congested environments

WiFi 6’s combination of MU-MIMO and OFDMA adds up to improved speed and capacity in crowded networks where many devices are competing for bandwidth. Ideal for public spaces, sports stadiums, or IoT environments.
