+<h2>Unit Overview</h2>
+<p>This unit discusses how computers are connected through wireless networks, and how mobility of access stations can be achieved in various ways to meet users’ needs.</p>
+<p>Today, wireless and mobile networks have become important components of computer networks. Understanding their underlying protocols and technologies is essential for anyone who wants a good comprehension of networking technologies. In this unit, you will learn what constitutes wireless and mobile networks, how they work, and the details of their underlying technologies.</p>
