## WiFi connectivity

Wi-Fi has played a foundational role in delivering IoT innovation, providing pervasive connectivity to connect a wide variety of “things” to each other, to the internet, and to 19.5 billion Wi-Fi devices in use around the world. Wi-Fi enables users to automate their smart homes and connect a wide variety of connected household objects, monitor supply chains and other critical functions in real time in industrial facilities, and unlock business value by increasing productivity and efficiencies for both enterprises and hybrid-work scenarios.

#### Wi-Fi devices can operate in two main modes:

* Access Point (AP) Mode: In this mode, a device (usually a wireless router) creates a local area network for Wi-Fi devices. It manages wireless clients, assigns IP addresses, and handles their access to the wired network.
* Station Mode (STA) or Client Mode: In this mode, a device joins an existing network, similar to how a smartphone connects to a home Wi-Fi network.

WiFi APs can operate in multiple modes. Each mode is designed for a particular scenario, impacting how devices connect and communicate within a network. These modes include local mode, bridge mode, client mode, sniffer mode, rogue detector mode, and repeater mode.

RW007 is a SPI/UART high-speed WiFi/BLE module based on Cortex-M4 WIFI SOC developed by Shanghai Ruiside Electronic Technology Co., Ltd. In SPI mode, users only need to reserve 1 set of SPI signals, one interrupt input, and one IO output, including a total of 8 pins for power and ground.
