Until recently, built-in wireless LAN (WLAN) communication functions have been limited to only a few items, such as personal computers and smartphones. Today, WLAN functions are a part of many different products, including digital cameras, robotic vacuum cleaners, TVs, printers, sensors and machinery, with many more IoT products coming in the future. Generally, these products rely on a built-in WLAN module for WLAN communications.
