Too much of anything can be a bane. The explosive proliferation of computing services in everyday life resulted in a tangle of wires with many pitfalls – maintenance was difficult, heat generation was intense, it played havoc with hardware organization and aesthetics. Computer networks became necessary and then ubiquitous and many of these applications required wireless access for optimum efficiency and usage.

Wi-Fi is one of the technologies that emerged to provide a base for wireless networking. More technically, Wi-Fi is a brand name licensed to Wi-Fi Alliance that is used to define the underlying technology of Wireless LANs which used the IEEE 802.11 specifications. The commonly used expansion of Wireless Fidelity is a popular misconception that has been shown favor and disfavor alternately.

Primarily intended for various mobile computing and networking, its usage has increased to include internet access, mobile gaming, consumer devices connectivity, and in emerging Intelligent Transportation System. The system works through various access points that create a service area popularly called hotspots – within a hotspot, a properly configured base unit can communicate with other configured devices wirelessly. The size of the hotspots can differ from a single room to a whole city block or small town, depending on the needs and investment available. Thanks to Wi-Fi, wireless networking work more seamlessly.
