In this study, a general overview of the current trend wireless network has been presented the explosive parallel growth of both the Internet and cellular telephone services are becoming the two most important phenomena that impact the required modern feasible and secure telecommunications. A wireless service technology has become well-known in technology markets. WLAN implemented the development of the wired LAN. Industries produce the required components, which lead to the fast developments in designing and implementing of such networks. The merging of wireless network deemed to be a solution to some of the problems of the wired networks. In this survey study, we will try to discuss the advantages of wireless devices and indicate the challenges involved in this technology from the point of view of its foundation, architecture, requirements, its components, and protocols.
