Think of interoperability as the ability of two or more devices to seamlessly operate without causing interference with each other. The WiFi Alliance certifies newly-manufactured WiFi equipment by testing it among other WiFi devices to ensure network stability and interoperability. In 1999, the non-profit WiFi Alliance was formed. It was introduced in 1997 to consumers as “WiFi 1” with the release of the 802.11 standards for local area networks from the IEEE (Institute of Electrical and Electronics Engineers). Defense Department, WiFi itself is relatively new. While the internet’s history can be traced back to the 1960s with the creation of ARPANET (Advanced Research Projects Agency Network) by the U.S. The range of the network is between 150 to 300 feet. These devices can then exchange information to create a wireless local area network (WLAN). A WiFi signal is transmitted by an internet service provider to the router to allow internet access to devices such as computers, tablets, cell phones, and laptops.
WiFi is a wireless technology that allows devices to connect to the internet through a WiFi router. 'Bluetooth and WiFi are both radio frequency technologies that wirelessly connect electronic devices, but there are some important differences in how they operate.' - Dave Seeman Click To Tweet Understanding WiFi
