This same signal will be transmitted, via an antenna, to a decoder known as the router. The computer should include a wireless adapter that will translate data sent into a radio signal. Like mobile phones, a Wi-Fi network makes use of radio waves to transmit information across a network. To start a Wireless connection, it is important that the wireless router is plugged into the internet connection and that all the required settings are properly installed. One can use advanced softwares like Wirelessmon to detect and request connection to Hotspots. Areas which are enabled with Wi-Fi connectivity are known as Hot Spots.
Wi-Fi provides wireless connectivity by emitting frequencies between 2.4GHz to 5GHz based on the amount of data on the network. To access this type of connection, one must have a wireless adapter on their computer. Wi-Fi is increasingly becoming the preferred mode of internet connection all over the world. Each of them uses different solutions for the topics above so one can't just explain how Wi-Fi works. Which uses rather complicated mathematics all the time (like Fourier Transforms, Auto correlation and Probability Theory)Īnd to make it even more complicated there are different Wi-Fi standards. To understand those model you'll need basic knowledge about the mathematical description of Systems.
There are different ways to do this and Wi-Fi uses one of them. This allows multiple people to be in the same wireless network. There are rather complicated solutions to optimize the received signals.Īnother step in coding that allows you to send the information in a way only a certain Person can read the information. You need to know how the environment (walls, reflections, losses) affect your signal. There are different ways to store information on an electromagnetic wave, one of them is used on Wi-Fi.Īnd that is just the beginning you could try sending data with that knowledge but usually you need to know a bit more and it would only work like that if you have a direct connection without losses. Modulation is the step that brings together the information and the wave. You need to know about antennas and amplifiers and losses to understand wi-fi hardware and ranges limits (or even prices of the hardware).
They are used to send information over long distances.

And you need to know how to correct errors that will appear when you transmit the information. You need to know how information is stored on your computer and how to translate words into bits in an efficient way. So let me just give a short introduction to the different technologies: i discussed things like that with a friend and the easy answer for the layman is: It uses so many different technologies that it's hard to explain in a few sentences. I study the thing and wi-fi just is complicated. This higher frequency allows the WiFi system to transmit a significantly higher amount of data. Typically a WiFi system will transmit either in 2.4 GHz or 5 GHz. The first is that WiFi operates at a much higher frequency then these other devices. There are a few notable differences between a WiFi system and a cell phone or a walkie talkie.

The WiFi router will send out a signal that only your computer can decipher, you will translate it and download the information. In order to download information, this process will work in reverse. Today, the device is embedded inside the laptop and you will not even see it. In older laptops this was done by an external card with a large antenna. This signal is encrypted so only the proper device that can decrypt will be able to analyze and decode the signal. Your laptop will take the outgoing data you want to send, translate that information into a radio signal and transmit it using an antenna. This simple device evolved into the cell phone, and now the same core technology is being used in WiFi systems to connect computers up to the internet. Probably the earliest examples of WiFi are the talk radio. In those devices however there is only one way communication. A wireless network will use radio wave to communicate similar to how your television and radio works. A wireless connectivity of internet that let you connect to the internet.Īt its heart, wireless networking is based around technology that has been in use for almost a hundred years now.
