WIFI AND ITS WORKING

How does Wi-Fi work?
Frequencies:;

A wireless network will transmit at a frequency level of 2.4 GHz or 5 GHz to adapt to the amount of data that is being sent by the user. The 802.11 networking standards will somewhat vary depending mostly on the user's needs, as explained below: 1. The 802.11 a will transmit data at a frequency level of 5 GHz. The Orthogonal Frequency-Division Multiplexing (OFDM) used enhances reception by dividing the radio signals into smaller signals before reaching the router. You can transmit a maximum of 54 megabits of data per second. 2. The 802.11 b will transmit data at a frequency level of 2.4 GHz, which is a relatively slow speed. You can transmit a maximum of 11 megabits of data per second. 3. The 802.11 g will transmit data at 2.4 GHz but can transmit a maximum of 54 megabits of data per second as it also uses an OFDM coding. 4. The more advanced 802.11 n can transmit a maximum of 140 megabits of data per second and uses a frequency level of 5 GHz. What is a Hot spot?The term Hot spot is used to define an area where Wi-Fi access is available. It can either be through a closed wireless network at home or in public places like restaurants or airports. As stated earlier, to be able to access Hot spots your computer should include a wireless adapter. If you are using an advanced laptop model, it will probably include a built-in wireless transmitter already. Otherwise you can purchase a wireless adapter that will plug into the PCI slot or USB port. Once installed, your system will automatically detect the Wi-Fi hots pots and request connection. If not, you should use a software to handle this task for you. 1. The 802.11 a will transmit data at a frequency level of 5 GHz.

Like mobile phones, a Wi-Fi network makes use of radio waves to transmit information across a network. The computer should include a wireless adapter that will translate data sent into a radio signal. This same signal will be transmitted, via an antenna, to a decoder known as the router. Once decoded, the data will be sent to the Internet through a wired Ethernet connection. As the wireless network will work as a two-way traffic, the data received from the Internet will also pass through the router to be coded into a radio signal that will be receipted by the computer's wireless adapter.
