The Wi-Fi network has, over time, proved itself to be very useful, and unarguably is one of the bests world's most popular network connections. Millions of homes, business (small, medium and even large scale businesses), public locations are supported by Wi-Fi connections.

Even though many people, (including you and I) have access to or at least have had access to Wi-Fi connections; how much do you know about it. Let's see how well you fare :) 
<ol>
<li>Wi-Fi Connections do not require an access point. Some people think they need to find a router, a public hotspot, or other kind of access point in order to set up Wi-Fi connections.this is not true! Wi-Fi also supports a connection type called ad hoc mode that allows devices to network in peer-to-peer fashion. </li>
<li>Industry vendors created the first version of Wi-Fi (802.11) back in 1997 (that's some 17 years ago). The market for consumer products exploded starting in 1999 when both 802.11a and 802.11b became official standards. </li>
<li>Wireless Broadband Routers are also Wi-Fi Access Points. An Access Point (AP) is a type of wireless hub used for coordinating the network traffic of multiple clients. One reason why wireless broadband routers make home networks much easier to build, is that they function as Wi-Fi access points. </li>
<li>A Wi-Fi network can span many Kilometers, or just a few meters. The typical range of a Wi-Fi network varies depending on the type of obstructions the radio signals encounter between connection endpoints. While 30m or more of range is typical, a Wi-Fi signal may fail to reach even half that distance if heavy obstructions exist on the radio signals' path. Using special Wi-Fi range extender devices, an administrator can extend the reach of their network to overcome these obstructions and expand its range many fold in other directions. A few Wi-Fi networks spanning 275 km and more have even been created by network enthusiasts over the years. </li>
<li>Wi-Fi connection speed varies with distance. When you join a Wi-Fi network and the access point is nearby, your device will typically connect at its maximum rated speed (e.g., 54 Mbps for most 802.11g connections). Gradually move away from the AP, though, and eventually your reported connection speed will drop to 27 Mbps, 18 Mbps, and lower.A cleverly-designed feature of Wi-Fi called dynamic rate scaling causes this phenomenon. Wi-Fi maintains a reliable connection over longer distances when it transfers data slower, by avoiding flooding the wireless connection with data and subsequent retry requests that happen when one network client starts to fall behind on processing its messages. </li>
<li>Wi-Fi is not the only form of wireless networking.News articles and social sites sometimes refer to any kind of wireless network as "Wi-Fi." While Wi-Fi is extremely popular, other forms of wireless technology are also in widespread use. Smartphones, for example, commonly use a combination of Wi-Fi together with cellular Internet services based on LTE or older "3G" systems.Bluetooth wireless remains a popular way to connect phones and other mobile devices each other (or to peripherals like headsets) over shorter distances.Home automation systems employ different kinds of short-range wireless radio communications such as Insteon and Z-Wave. </li>
<li>Some types of Wi-Fi are incompatible with each other.Some believe that any Wi-Fi system can network with any other Wi-Fi system as long as all their security settings match. While it's true that 802.11n,802.11g and 802.11b Wi-Fi standard equipment can all network together, the alternative 802.11a standard does not support cross-compatibility with any of these others. Special Wi-Fi access points that support both 802.11a and 802.11b (or higher) radios must be used to bridge the two. Other compatibility issues also can arise between Wi-Fi products from different vendors if both build their Wi-Fi equipment using non-standard proprietary extensions. Fortunately, compatibility limitations like these are not often found in practice nowadays. </li>
</ol>
Well, that's it. How well did you fare in your assessment of how much you knew about the Wi-Fi. I am guessing you did fairly well :).
