Wi-Fi was intended to be used for mobile devices, Local Area Networks and internet access through Access Points. The importance of communication of information and the technologies required for are stated. The importance of Wi-Fi technology and its application in libraries are stated. If wi-fi broke the shackles of cable networking, wi-max took it a step ahead. Wi-max could just be the most significant technology todate, in making wireless access ubiquitous. 4G will enable wireless subscribers to view high-definition television programming through wireless broadband connections. Wi-fi applications in libraries is like any other implementation, the vital aspect to a successful wireless implementation is also good planning. The technicalities of Wi-Fi and problems are discussed. Suitable solutions to over come these problems are givenenRadio wavesFrequenciesWireless Fidelity(Wi-Fi)Access PointsArticle
