The S6822WT is a multi-functional wireless module developed by Skyworks Solutions Inc. It combines the latest wireless networking technologies including Wi-Fi, Bluetooth and Zigbee, allowing resource constrained devices to connect and interact with other electronic devices. It operates in the 2.4 GHz frequency band, supporting b/g/n (Wi-Fi), BT 4.2 Low Energy (LE) and Zigbee (IEEE 802.15.4). The S6822WT is designed to meet the requirements of low-power, low-cost applications such as home automation, IoT devices, smart home devices, electric meters and industrial sensors and control applications.

The S6822WT utilizes an integrated 802.11b/g/n radio, a Bluetooth radio and an IEEE 802.15.2 platform controller hub (PCH). The 802.11b/g/n radio offers up to 72 Mbps throughput when operated in 802.11g mode and 150 Mbps throughput when operated in 802.11n mode. The Bluetooth radio supports Bluetooth 4.2 LE and provides up to 128 Kbps in data rate. In addition, the S6822WT also features an external RF switch, a 2.4 GHz antenna interface and a UART interface for external control.

The S6822WT supports multiple operating modes to provide flexibility in different applications. For Wi-Fi applications, the S6822WT supports both station mode (STA) and access point mode (AP). In station mode (STA), the S6822WT connects to an access point such as a router or a wireless hardware. In access point mode (AP), the S6822WT acts as an access point, allowing other Wi-Fi enabled devices to connect to it. The S6822WT also supports Bluetooth LE, allowing it to communicate with Bluetooth enabled devices. In addition, it supports IEEE 802.15.4 protocol, allowing it to communicate with ZigBee enabled devices.

The S6822WT uses an advanced power management system to reduce power consumption in low-power applications. The power management system is capable of automatically switching between low-power and high-power states depending on the activity. The S6822WT has integrated support for the IEEE 802.11 Power Save (PS) function, allowing the device to switch between multiple power states to conserve power while maintaining Wi-Fi connection. In addition, the S6822WT also supports the IEEE 802.15.4 Low-Power Listening (LPL) function to reduce energy consumption while maintaining ZigBee connection. For Bluetooth applications, the S6822WT supports Bluetooth LE Advertising mode to reduce power consumption.

The S6822WT supports advanced security features such as Wi-Fi Protected Setup (WPS), Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2) to protect the wireless IEEE 802.11g and 802.11n networks, providing a secure connection to other devices. It also supports AES encryption for greater security in ZigBee communication. The S6822WT is also able to connect to the “Secure Connect” Platform from Skyworks Solutions Inc. for easier integration with cloud-based services.

In summary, the S6822WT is a high-performance, low-power, multi-function wireless module developed by Skyworks Solutions Inc. It supports popular wireless networking technologies, including Wi-Fi, Bluetooth and Zigbee. Its advanced power management and security features make it an ideal solution for low-power, resource constrained applications.
