Wireless Networks: data that travels through the air
When networking cabling was first introduced, it was a phenomenal success. File sharing across the entire network because so easy and convenient. The creation of network devices like hubs and switches made it possible for multiple computers to be connected to one another. The use of routers further extended the distance by which data is able to be transmitted and received.
Just as everything has it pros and cons, so does data network cabling. The presence of cables can easily clutter the work area, and increases as the number of communication devices are added to the existing network. With the advent of portable devices and gadgets like laptops, smart phones, tablet PCs and notebook PCs, it became clear that using wired cabling media is not gonna make things look portable in the first place! There has to be a way for data to be transmitted without having to connect cables to your laptops. Or imagine what it feels like if, in order to use your smart phones, you have to plug it first to a communication outlet using a network cable?
The answer to this dilemma is to go wireless. Making information travel through the air waves is definitely a sound idea. Instead of having cable connector jacks protruding from the device, you have antenna instead. Modern technology made it even possible to hide the antennas, or at least redesign it into a different shape that does not have to appear like a pointed stick outside of your communication device.
The use of wireless networks eventually gave way to the creation of WiFi networks, short for Wireless Fidelity. All you have to do is to configure your laptops or notebook PCs to synchronize with that of the wireless router, and then you are all set. Worried about security issues? No problem, because wireless devices like routers can be configured with access restrictions like the use of encrypted passwords, in order to limit the number of authorized users. You can also put restrictions by schedule that will make the wireless network inaccessible during certain periods of the day. Furthermore, you can even put restrictions that will limit which application or website can be made accessible, further ensuring that the wireless network is safe from possible intrusion and maximizing the productivity level of the users who access the network.
