5. ** Enhanced MU-MIMO** : Support more devices to connect at the same time, improving network capacity.

6. ** Reduced latency ** : Optimized technology reduces network latency and improves user experience.


Technical analysis: Why does the QCN6224 and QCN6274 support WiFi 7, but the QCN6024 does not?


#### Hardware architecture

Many of WiFi 7's improvements require support from the underlying hardware architecture. The QCN6224 and QCN6274 were designed with these requirements in mind, such as higher processing power, wider channel support, and enhanced QAM capabilities. Due to its early design, the QCN6024 hardware architecture does not support the technical features required for WiFi 7.


#### channel bandwidth

WiFi 7 supports up to 320MHz channel bandwidth, while the QCN6024 only supports 160MHz. This means that the QCN6024 cannot meet the bandwidth requirements of WiFi 7 on the hardware, which limits its improvement in data transmission rate.


#### Multi-link operation

WiFi 7 introduces multi-link operation (MLO), which allows devices to transmit data simultaneously over multiple frequency bands. The QCN6224 and QCN6274 have the hardware and software capabilities to support this feature, while the QCN6024 was not designed with this feature in mind and therefore cannot achieve this.


#### Higher QAM

The QCN6224 and QCN6274 support 4K-QAM, while the QCN6024 only supports 1024-QAM. This difference allows the first two to achieve higher data transfer efficiency at the same bandwidth.


#### Processing capacity

The complex nature of WiFi 7 requires more processing power. The QCN6224 and QCN6274 are equipped with stronger processors and higher memory bandwidth to handle the complex protocols and large data volumes of WiFi 7, while the QCN6024's processing power is relatively insufficient to meet the needs of WiFi 7.


### Conclusion


The QCN6224 and QCN6274 meet the technical requirements of WiFi 7 due to their advanced hardware architecture, support for wider channel bandwidth, multi-link operation, support for higher QAM modulation, and enhanced processing power. Due to its early design, the hardware and software architecture of QCN6024 cannot support the features of WiFi 7, so it can only support the WiFi 6 standard. As wireless communication technology continues to evolve, chip upgrades will continue to drive the advancement of wireless networks, bringing users a more efficient and faster connection experience.
