How do IPQ9574 and IPQ9554 connect QCN9274 for WiFi7 connectivity?
The IPQ9574 and IPQ9554 are high-performance wireless networking chips developed by Qualcomm. They have some differences in function, mainly reflected in the following aspects:

1. Processor performance: The IPQ9574 uses a quad-core ARM Cortex-A53 processor with a speed of up to 1.4GHz, while the IPQ9554 uses a dual-core ARM Cortex-A53 processor with a speed of 1.0GHz. Therefore, the IPQ9574 is more powerful in terms of processing speed and performance.

2. Network speed: IPQ9574 supports up to 4x4 MU-MIMO (multi-user multiple-input multiple-output) configuration, which can achieve higher network speed and throughput. The IPQ9554 supports up to 3x3 MU-MIMO configurations.

3. Wireless standard support: IPQ9574 supports the 802.11ac Wave 2 standard, which can provide faster wireless speeds and better network coverage. The IPQ9554 supports 802.11ac Wave 1.

4. Security: Both IPQ9574 and IPQ9554 support Qualcomm security technologies such as WPA3 encryption and hardware-level Secure encryption engine to provide higher network security.

Overall, the IPQ9574 is more powerful than the IPQ9554 in terms of processor performance, network speed, and wireless standards support. These differences make the IPQ9574 suitable for more demanding wireless network applications, such as enterprise-class wireless networks and high-density environments. The IPQ9554 is suitable for general home and small office scenarios.

Why does their built-in 2.4G not support WiFi7?

The IPQ9574 and IPQ9554 chips are developed by Qualcomm, and the reason why their 2.4GHz wireless band does not support the WiFi 7 (i.e. 802.11be) standard may be due to the following considerations:

1. Technical limitations: WiFi 7 is a new wireless network standard that introduces a number of new technologies and improvements in the 2.4GHz band to provide higher speeds and better performance. However, due to the limited bandwidth in the 2.4GHz band, it may not be able to meet the higher speed and larger capacity requirements required for WiFi 7.

2. Compatibility considerations: The 2.4GHz band is a widely used band on which many older devices and traditional WiFi standards such as 802.11b/g/n operate. In order to ensure backward compatibility and device interoperability, it may be decided to continue to support older WiFi standards on the 2.4GHz band rather than introduce a new standard.

Therefore, if you want the WiFi7 function, you need to use the network card with the QCN9274 chip to achieve:

The QCN9274 chip is a Qualcomm chip that supports the WiFi 7 standard, which can provide higher speeds and better performance in the 2.4GHz and 5GHz bands. By using the network card with the QCN9274 chip, you can enjoy the new features and improvements that WiFi 7 brings.
