QCA9892 and QCA9890 2x2 802.11ac implements high performance Wi-Fi devices in the IPQ4019/IPQ4029 router

The difference between QCA9892 and QCA9890

The QCA9892 and QCA9890 are high performance 2x2 802.11ac Wi-Fi chips. They feature Qualcomm Atheros' fifth-generation Wi-Fi architecture that supports the latest IEEE 802.11ac standard and multi-user MIMO technology. These chips are capable of delivering high-speed data transfer up to 1.3 Gbps and provide powerful security and network management capabilities.

Both QCA9892 and QCA9890 support dual-band operation, including 2.4 GHz and 5 GHz bands. They use a variety of technologies to improve Wi-Fi performance, such as Beamforming and MU-MIMO. In addition, they support 802.11r fast roaming, which enables seamless switching and ensures that the wireless connection is not interrupted.

These chips are typically used in high-end routers, enterprise-class wireless access points, and other high-performance Wi-Fi devices.

The QCA9892 and QCA9890 are both high performance 2x2 802.11ac Wi-Fi chips, they are very similar in functionality and specifications, but there are a few differences:

The QCA9892 has a maximum speed of 867 Mbps, while the QCA9890 has a maximum speed of 1.3 Gbps.

The QCA9892 uses WCN3680B and the QCA9890 uses WCN3680.

The QCA9892 uses the QCA9882 wireless signal processor, while the QCA9890 uses the QCA9880.

Other than that, the features and specifications of the two chips are very similar, with both supporting dual-band operation, multi-user MIMO technology, Beamforming, 802.11r fast roaming and other features suitable for high-end routers, enterprise-class wireless access points, and other high performance Wi-Fi devices.

QCA9892 and QCA9890 mini pcie moudle in the IPQ4019 router implementation function

Both QCA9892 and QCA9890 are wireless networking chips that support 802.11ac and can be used as Mini PCIe modules in IPQ4019 routers for Wi-Fi connectivity. The main difference is that the QCA9892 supports Wave-2 technology, while the QCA9890 only supports Wave-1 technology. Wave-2 technology includes new features such as MU-MIMO, 160 MHz channels, and higher maximum data rates that increase the capacity and throughput of Wi-Fi networks, enabling more devices to connect simultaneously and providing faster speeds. Therefore, the QCA9892 is a better choice in scenarios where higher rates and greater capacity are required. At the same time, due to their smaller differences in chip size and power consumption, they can achieve similar Wi-Fi connectivity capabilities on IPQ4019 routers.
