What comes to your mind when your listen the word" Wi-Fi". In layman words it is nothing but a wireless connection that can be accessed without wires and cables. We all have accessed Wi-Fi connection but are unaware of it. This might be in airports or hotel rooms as these places are Wi-Fi enabled. The Wi-Fi technology has truly unplugged the world and the use of internet in our lives.

Gone is the Stone Age when computers were connected to routers and modems for internet connectivity. Today is the age of Wi-Fi connection as you can access internet anywhere and everywhere. Let us take a look at Wi-Fi technology with the help of computer support professionals.

Understanding the Concept of Wi-Fi

Wi-Fi is the abbreviated form of Wireless Fidelity. It is trademark name of standard wireless networking technology. It enables wireless access to the internet with the help of radio active connectivity. This technology is defined by IEEE 802.11 standard and has been designed to create uniformity in wireless networking products around the globe. In other words Wi-Fi is synonymous with wireless technology which is possible through advanced radio active communication techniques.

Now let us understand the components of Wi-Fi network. The most important component of Wi-Fi network is the wireless router. It is sort of connecting link between your laptop connected through a wireless network and internet. The transmitter as well as the radio signal converts digital signal to analog and analog signal back to digital. The speed of the data transmission on the network as well as the network security is dependant on wireless router. The next important component is the wireless adapter that is fitted in your laptop. This helps to receive and transmit wireless signals to the wireless router. Most of the wireless routers are fitted with Wi-Fi antennal boosters to increase the range of the signal.

How does Wi-Fi Work?

Now let us know how to Wi-Fi work? If you understand the concept of how radio signals work then understanding Wi-Fi signal is comparatively simple. Take for instance that you are in Wi-Fi enabled home and you want to access the internet through your laptop. At this situation the wireless adapter searches for signal. Once you switch on your laptop the attached or wireless adapter is operational. It searches for network source in your vicinity. The wireless adapter acts as transmitter as well receiver of radio signal. This also carries out the function of modem that coverts digital signals into analog and radio signals back to digital. Once the adapter gets signal through wireless router through radio waves, your PC gets registered with the wireless network for communication. The wireless router is connected to the ISP or Internet Service Provider with the help of an Ethernet port. The wireless router is the gateway for data transmission. The routers have the capacity to communicate over 2-4 GHz and 5 GHz radio frequencies. Therefore the higher frequency is the bandwidth for data transmission.
