The Qualcomm QCN9274 chip is a Wi-Fi chip that belongs to the 802.11ac standard, not a chip in the Wi-Fi 6E (802.11ax) or Wi-Fi 7 (802.11be) family. Although 802.11ac is no longer the latest Wi-Fi standard, it still has certain advantages in speed and power consumption, so it is still widely used in some devices.

Qualcomm QCN9274 chip, as the chip of Wi-Fi module, has the following strong advantages:

High-speed transmission: The QCN9274 chip supports the 802.11ac standard and provides data transmission rates of up to 867Mbps, which can provide faster Internet connection speeds and smoother online experience.

Low power consumption: The QCN9274 chip adopts the power management technology independently developed by Qualcomm, which can ensure high-speed transmission while reducing power consumption, extending battery life and improving device availability.

Multiple security protocols: The QCN9274 chip supports multiple security protocols, such as WEP, WPA, WPA2, and WPA3, ensuring the security and privacy of data transmission.

Powerful network connection capability: The QCN9274 chip supports various network connection modes, including Wi-Fi direct connection and hotspot sharing, meeting different user requirements.

Good compatibility: QCN9274 chip is compatible with a variety of operating systems and hardware platforms, can be widely used in a variety of terminal devices, such as smart phones, laptops, tablets, smart home, etc.

To sum up, the Qualcomm QCN9274 chip, as the chip of the Wi-Fi module, has the advantages of high-speed transmission, low power consumption, support for various security protocols, strong network connection capability, and good compatibility.

It supports both 2.4GHz and 5GHz bands and meets the requirements of 802.11ac. In the 2.4GHz band, the chip can support two channel widths, 20MHz and 40MHz. In the 5GHz band, three channel widths of 20MHz, 40MHz and 80MHz are supported, and the maximum transmission rate of 867Mbps can be achieved. It is important to note that the actual wireless transmission rate may be affected by many factors, such as environment, equipment, signal interference, and so on, so the actual rate may be lower than the maximum rate.

The Qualcomm QCN9274 chip does not come with a fixed-gain antenna, but can be used in combination with different gain antennas for optimal performance. In fact, antenna gain is not the only factor affecting the wireless transmission rate, other factors such as signal-to-noise ratio, transmission distance, channel width, bandwidth, and so on are also important. Therefore, in the practical application, it is necessary to consider various factors according to the specific situation, select the appropriate antenna and parameter configuration, in order to achieve the best performance.
