With the introduction of Wi-Fi 7 standard, network technology ushered in a new development opportunity. QCN974 and QCN6274 chips are widely used in the design of Wi-Fi 7 network cards with different configurations to meet the needs of different scenarios. This article will discuss in detail the application of these two chips in five different configurations of Wi-Fi 7 cards, and comparative analysis from all aspects.
#### **1. 4x4 2.4G network adapter **
- ** Frequency band ** : 2.4GHz
- ** Antenna configuration ** : 4x4 MIMO
- ** Features ** :
- ** Coverage ** : The 2.4 GHz band is known for its excellent penetration and wide coverage, making it suitable for use in environments with more obstacles.
- ** Interference ** : Due to the large number of devices in the 2.4 GHz band, it may face greater signal interference.
- ** Data rate ** : Compared to the high band, the 2.4GHz transmission rate is lower, but still able to meet the needs of most common network applications.
- ** Application Scenarios ** : Suitable for applications requiring wider coverage and better signal penetration, such as smart home devices and Internet of Things (IoT) devices.
#### **2. 4x4 5G network adapter **
- ** Frequency band ** : 5 GHz
- ** Antenna configuration ** : 4x4 MIMO
- ** Features ** :
- ** Coverage ** : The coverage of the 5 GHz band is relatively small, and the signal penetration is not as good as 2.4 GHz, but the performance is excellent over short distances.
- ** Interference ** : The 5 GHz band has less interference and can provide a more stable signal connection.
- ** Data rate ** : Compared to 2.4GHz, the transmission rate of the 5 GHz band is significantly improved, which is suitable for applications with high bandwidth requirements, such as high-definition video streaming, online games, etc.

#### **3. 4x4 6G network adapter **
- ** Frequency band ** : 6 GHz
- ** Antenna configuration ** : 4x4 MIMO
- ** Features ** :
- ** Coverage ** : The 6 GHz band has the smallest coverage and is suitable for high-speed data transmission over short distances.
- ** Interference ** : The 6 GHz band is currently relatively new and uses fewer devices, so there is very little interference and can provide a very stable connection.
- ** Data rate ** : Because the 6 GHz band has more spectrum resources, it can support higher data rates and lower latency, which is suitable for applications requiring ultra-fast connections.
- ** Application Scenarios ** : Suitable for high-performance applications in dense network environments, such as virtual reality (VR), augmented reality (AR), etc.
#### **4. 2x2 2.4G & 2x2 5G dual-band network card **
- ** Frequency band ** : 2.4GHz and 5GHz (dual frequency)
- ** Antenna Configuration ** : 2x2 MIMO for 2.4 GHz & 2x2 MIMO for 5 GHz
- ** Features ** :
- ** Coverage ** : Combines wide coverage of 2.4 GHz with high performance of 5 GHz to provide flexible network connectivity in different environments.
- ** Interference cases ** : By using two frequency bands simultaneously, interference can be reduced to a certain extent and connection performance can be optimized.
- ** Data rate ** : Flexible switching between different frequency bands, able to provide higher data rates when needed.
- ** Application Scenarios ** : Applicable to applications that require both coverage and performance, such as smart home and enterprise office networks.
#### **5. 2x2 5G & 2x2 6G dual-band network card **
- ** Frequency band ** : 5 GHz and 6 GHz (dual frequency)
- ** Antenna Configuration ** : 2x2 MIMO for 5 GHz & 2x2 MIMO for 6 GHz
- ** Features ** :
- ** Coverage ** : The 5 GHz band provides moderate coverage, while the 6 GHz band is suitable for high-speed transmission over short distances and can provide protection for applications with high bandwidth requirements.
- ** Interference cases ** : The combination of dual bands reduces interference, especially in the 6 GHz band, and you can enjoy a nearly interference-free network connection.
- ** Data Rate ** : The combination of high frequency bands provides support for applications requiring extremely high data rates and low latency.
- ** Application Scenarios ** : Suitable for application scenarios that require high network performance, such as real-time streaming media transmission in high-density device environments, online games, etc.
### ** Summary **
The QCN974 and QCN6274 chips provide a flexible and versatile Wi-Fi 7 solution by supporting multiple frequency bands and antenna configurations. Whether it is the 2.4 GHz band that focuses on the coverage range, or the 5 GHz and 6 GHz bands that pursue high data rates, different configurations can be selected according to the specific application scenario. These Wi-Fi 7 cards connect to the host device via the M.2 interface, giving device manufacturers and consumers a great deal of flexibility and an efficient wireless connection experience.
