Abstract Over the previous 25 years, the development of the Internet and the progress of wireless technologies have made an incredible impact on lifestyle around the world. Together, these two features have changed the communication requirements in domestic, public, and business scenarios. At the beginning of this decade, wireless devices became affordable and Wireless Local Area Network (WLAN) rapidly became more secure and the standard technology to connect laptops, and later tablets and smartphones, to the Internet is growing quickly. Nowadays, the WLANs offer unlimited broadband practice to consumers that have been in the past provided simply to connect wirelessly equipment inside a short range. The most recent and the up-and-coming standards solve technology problems or append new features to the existing 802.11 technologies and will be expected to beat a number of standing troubles with 802.11.The current trend of new-generation wireless networks is their use in the design and the building of smart cities. This technology guarantees better and healthier cities through the implementation of environment-based applications allowed by WLAN, robust environmental sensors, and low energy consumption. WLANs can be one of the ideal solutions to implement this kind of platforms.This chapter focuses on this technology. The first part of this chapter illustrates the basics of the IEEE 802.11 standard. This includes a survey of WLAN concepts and terminology, Physical and Medium Access Control (MAC) Layers, applications of WLANs, and spread spectrum communication. In the second part of this chapter, we present the history behind the development of the standard and we detail the features of the IEEE 802 family that have been published. Then we will describe some upcoming standards and we discuss some key open problems of the IEEE 802.11 standard such as mobility, energy, security, and quality of service. The last part of this chapter focuses on the applications of WLANs to smart cities and homes, and the challenges posed. © 2016 Elsevier Inc.
