1. Amazing Speed
The biggest promise of this technology is speed. It offers up to 46 Gbps under ideal conditions, an impressive improvement over Wi-Fi 6's 9.6 Gbps.
This capability is essential to meet the growing demand for high-performance applications such as streaming 8K, cloud-based gaming and augmented reality.
2. Multi-Link Operation (MLO)
The technology MLO allows devices to simultaneously use multiple frequency bands — 2.4 GHz, 5 GHz, and 6 GHz.
This results in faster, more stable connections, even on congested networks.
3. 320 MHz channels
The width of the channels has been increased to 320 MHz, doubling the capacity compared to previous generations.
This enables even faster data transfers, ideal for environments with multiple connected devices.
4. 4096-QAM modulation
O 4096-QAM (Quadrature Amplitude Modulation) significantly increases the density of transmitted data, improving spectrum efficiency and reducing interference.
These advancements position Wi-Fi 7 as the cornerstone to support futuristic applications that demand high bandwidth and low latency.
Wi-Fi 7 vs. previous generations
The table below illustrates the main differences between Wi-Fi 7 and its previous versions:
| Feature | Wi-Fi 5 | Wi-Fi 6 | Wi-Fi 6E | Wi-Fi 7 |
|---|---|---|---|---|
| Maximum Speed | Up to 3.5 Gbps | Up to 9.6 Gbps | Up to 9.6 Gbps | Up to 46 Gbps |
| Latency | Moderate | Improved | Improved | <1 ms |
| Available Bands | 2.4GHz, 5GHz | 2.4GHz, 5GHz | Includes 6 GHz | 2.4GHz, 5GHz, 6GHz |
| Multi-Device Capability | Moderate | High | High | Superior |
| Energy Efficiency | Average | High | High | Superior |
The combination of these improvements sets this release apart as a game-changer in connectivity.
Impacts of Wi-Fi 7 on society
