Product description

The Qualcomm QCA-9981-0-156DRQFN-MT-01-0 is a robust wireless networking solution designed for high-performance Wi-Fi applications. It utilizes the 802.11ac Wi-Fi standard, delivering data rates of up to 1.3 Gbps in the 5GHz frequency band and 450 Mbps in the 2.4GHz band, making it suitable for tasks such as HD video streaming, online gaming, and data-heavy cloud-based applications.

This chipset supports advanced multi-user MIMO (MU-MIMO) technology, allowing for simultaneous communication with multiple devices, a key feature for environments with many connected devices such as smart homes, offices, and public Wi-Fi networks. By using MU-MIMO, it ensures that bandwidth is efficiently allocated, reducing lag and improving overall network performance. Beamforming technology further enhances the quality of the connection by directing the Wi-Fi signal toward the specific devices, improving both range and connection stability, even in areas with signal interference.

The QCA-9981 supports dual-band operation, ensuring optimal performance by utilizing both the 2.4GHz and 5GHz frequency bands. The 2.4GHz band offers extended range, while the 5GHz band delivers faster speeds and is ideal for data-heavy tasks. The use of 256-QAM modulation also enables higher data rates, ensuring faster and more reliable data transmission.

The security features built into the QCA-9981 include WPA, WPA2, and WPA3 encryption standards, providing a high level of security to protect networks from unauthorized access and cyber threats. Additionally, this chip is designed for low power consumption, making it an excellent choice for energy-efficient devices like wireless routers, access points, and IoT devices that require constant connectivity but need to conserve power.

Its small 156-pin DRQFN form factor makes it easy to integrate into compact designs, and its wide operating temperature range (-40°C to +85°C) ensures reliability in both consumer and industrial applications, including harsh environments.
