1.DR9274-4X4 2.4G
The DR9274-4X4 2.4G network card is designed for the 2.4GHz band with a 4x4 MIMO antenna configuration and is connected to the main device via the M.2 interface.
The long wavelength of the 2.4GHz band makes it excellent at penetrating obstacles and is suitable for use in environments with large coverage areas, especially in indoor environments with more walls. Everyone knows that 2.4G has a relatively low data transfer rate, but its stability and wide coverage make it the perfect choice for devices that need better signal penetration.
2. DR9274-4X4 5G
The DR9274-4X4 5G network card focuses on the 5 GHz band, also using a 4x4 MIMO antenna configuration, and is connected to the main device through the M.2 interface.
Compared to the 2.4GHz band, the 5 GHz band offers higher data transfer rates and is ideal for applications that require high-speed network connections, such as high-definition video streaming, online gaming, and more. But in environments with less interference, the 5 GHz band offers excellent network performance and low latency.
3. DR9274-4X4 6G
The DR9274-4X4 6G network card is designed for the 6 GHz band with a 4x4 MIMO antenna configuration and is connected to the main device via the M.2 interface.
A significant advantage of the 6 GHz band is that it provides more spectrum space, allowing for higher bandwidth and lower interference, which is particularly important in dense Wi-Fi environments. The network card is particularly suitable for applications that require ultra-high speed transmission and low latency, such as virtual reality (VR) and augmented reality (AR).
4.DR9274-DB 2X2 2.4G & 2X2 5G
The DR9274-2X2 2.4G & 2X2 5G network card supports both 2.4GHz and 5GHz dual bands, uses a 2x2 MIMO antenna configuration, and connects to the main device via the M.2 interface.
This design allows the device to switch between the two frequency bands on demand, providing flexible network connectivity in different application scenarios. The 2.4 GHz band provides a wide range of coverage, while the 5 GHz band is able to provide higher data transfer rates. Therefore, the network card is particularly suitable for applications that require both coverage and data rate, such as smart home systems and Internet of Things (IoT) devices.
5. DR9274-2X2 5G & 2X2 6G
Finally, the DR9274-2X2 5G & 2X2 6G network card supports dual bands of 5 GHz and 6 GHz, again in a 2x2 MIMO antenna configuration, and is connected to the main device via the M.2 interface.
This combination enables devices to provide high data rates in the 5 GHz band while enjoying greater spectrum space in the 6 GHz band, suitable for applications with high bandwidth requirements. This network card is particularly suitable for use in dense network environments and can provide an ideal solution for devices requiring low latency and high-speed connections.
Summary
The QCN974 chip supports a variety of frequency bands and antenna configurations, and connects to the main device through the M.2 interface, providing a rich choice for different application scenarios. Whether it's the 2.4GHz band that requires wider coverage, or the 5 GHz and 6 GHz bands that pursue higher data rates, the different DR9274 series network cards are designed to meet every need. These designs open up more possibilities for device manufacturers in the Wi-Fi 7 era, enabling them to provide consumers with more efficient and flexible wireless connectivity solutions.
