How To Measure A WiFi SOC?

To guarantee dependable and effective wireless communication, a decent WiFi SoC should adhere to a set of requirements. The following are some crucial specifications that a WiFi SoC must meet.

IEEE 802.11 Standards

At least one IEEE 802.11 standard, including the most recent 802.11ax (also known as Wi-Fi 6), as well as 802.11a, 802.11b, 802.11g, 802.11n, and 802.11n, should be supported by the WiFi SoC. Wireless communication is compatible with these specifications and protocols, which include data speeds, channel widths, modulation techniques, and security measures.

Wi-Fi Alliance Certifications

The WiFi SoC should be certified by the Wi-Fi Alliance, a world organization that promotes interoperability and standards compliance in WiFi devices. Certifications like Wi-Fi CERTIFIEDTM 6 or earlier generations ensure that the SoC complies with specific performance and interoperability criteria in order to ensure compatibility with other certified WiFi devices.

WPA3 Security

The most recent WiFi security standard, WPA3 (Wi-Fi Protected Access 3), offers improved encryption and protection from a variety of security issues. A decent WiFi SoC must be WPA3 compatible if you want dependable and secure wireless connections.

MIMO and Beamforming

Several Input Beamforming and Multiple Input Multiple Output (MIMO) technologies enhance WiFi performance and coverage. A WiFi SoC that supports MIMO and beamforming may send and receive several data streams simultaneously when employing multiple antenna systems, boosting throughput and range.

IoT Protocols

Depending on the specific use case, a good WiFi SoC might potentially manage several IoT protocols and standards, like MQTT, CoAP, and others. These protocols enable efficient and convenient communication between IoT devices and cloud services or other IoT infrastructure.
