The security standard, [[Wi-Fi Protected Setup]], allows embedded devices with a limited graphical user interface to connect to the Internet with ease. Wi-Fi Protected Setup has 2 configurations: The Push Button configuration and the PIN configuration. These embedded devices are also called The [[Internet of things]] and are low-power, battery-operated embedded systems. Several Wi-Fi manufacturers design chips and modules for embedded Wi-Fi, such as GainSpan.<ref>{{cite web

Increasingly in the last few years (particularly {{As of| 2007 | lc=on}}), embedded Wi-Fi modules have become available that incorporate a real-time operating system and provide a simple means of wirelessly enabling any device that can communicate via a serial port.<ref>{{cite web

These Wi-Fi modules are designed by [[OEM]]s so that implementers need only minimal Wi-Fi knowledge to provide Wi-Fi connectivity for their products.

In June 2014, [[Texas Instruments]] introduced the first ARM Cortex-M4 microcontroller with an onboard dedicated Wi-Fi MCU, the SimpleLink CC3200. It makes embedded systems with Wi-Fi connectivity possible to build as single-chip devices, which reduces their cost and minimum size, making it more practical to build wireless-networked controllers into inexpensive ordinary objects.<ref>{{Cite web|url=https://www.macinstallations.com/wifi-connectivity-explained/|title=Wifi Connectivity Explained {{!}} MAC Installations & Consulting|language=en-US|access-date=9 February 2020|archive-date=5 May 2020|archive-url=https://web.archive.org/web/20200505091852/https://www.macinstallations.com/wifi-connectivity-explained/|url-status=live}}</ref>
