Mini PCIe WiFi card SOC-QCA9880 vs. QCA9882: 802.11ac Dual-Band Wireless Chipset Showdown

A Mini PCIe (Small PCI Express) network adapter is a network adapter card that plugs into the Mini PCIe slot of a computer or other device. Peripheral Component Interconnect Express (PCI Express) is a standard bus interface used to connect the hardware inside a computer. Mini PCIe is a miniaturized version of the PCI Express standard. It is commonly used in lightweight portable devices and embedded systems.

When a Mini PCIe WiFi network card is installed on the router, the main function is to add wireless networking capabilities to the router. In this way, routers can not only provide wired network connections, but also support wireless connections, enabling more flexible network coverage and connection methods. Here are some other possible claims about what a Mini PCIe WiFi card does on a router:

Provides portability and mobility: The addition of a Mini PCIe WiFi network card makes the router more flexible and can provide portable wireless networks in different locations. This is useful for providing Internet connectivity during travel, events, or emergencies.

Enhanced connection options for user devices: By installing a WiFi network card, the router can support devices connected via WiFi, such as laptops, smartphones, tablets, etc., providing users with more network connection options.

Dealing with multi-device environments: In a home or office, there are sometimes a large number of wireless devices that need to be connected to the network. Adding a Mini PCIe WiFi network card can help the router better cope with multi-device environments and improve network capacity and performance.

Coverage of dead corners and hard-to-wire areas: Some areas may be difficult to connect to the network by wired means due to structural or other reasons, and adding WiFi capabilities can cover these dead corners and provide wider network coverage.

Overall, the role of the Mini PCIe WiFi network card is to expand the capabilities of the router, so that it has more connection options, improve the flexibility and applicability of the network.

As an ODM/OEM that designs, develops and produces WiFi products, Wallys has designed three mini pcie WiFi cards using Qualcomm QCA9880/QCA9882 chip and wireless solution with high performance and dual frequency operation to meet the needs of our customers and win more WiFi market.
Let's look at the difference between the two chips
1. Frequency band and bandwidth
QCA9880: The QCA9880 supports dual-band operation, including 2.4GHz and 5GHz bands. This allows it to provide a wider bandwidth, suitable for high-density network environments.

QCA9882: Similar to the QCA9880, the QCA9882 also supports both 2.4GHz and 5GHz bands, providing users with flexible dual-band options to adapt to different network needs.

2. MIMO technology
QCA9880: This chip supports multiple-input multiple-output (MIMO) technology, which improves connection performance and stability by simultaneously using multiple antennas to transmit and receive data. This is important for scenarios that require large volumes of data transfer.

QCA9882: Similar to the QCA9880, the QCA9882 also utilizes MIMO technology to provide users with more reliable wireless connectivity, especially in high-density user environments.

3. 802.11ac standard
QCA9880: complies with the 802.11ac standard, enabling it to provide faster wireless data transfer speeds. This makes the QCA9880 ideal for high performance networking needs.

QCA9882: Also compliant with the 802.11ac standard, it provides users with advanced wireless connectivity technology that supports higher data rates and more reliable connections.

4. Application scenario
QCA9880: Commonly used in enterprise-class WiFi solutions, high-density network environments, and applications where network performance is strictly required. Its high bandwidth and performance make it ideal for handling large numbers of users and devices.

QCA9882: Suitable for medium - and high-end routers and enterprise-class wireless access points. Excellent performance in scenarios requiring high performance and stable connectivity, suitable for a variety of application requirements.
