The invention of WiFi, a revolutionary tool that has changed the world.

WiFi (also Wi-Fi) is a technology that allows electronic devices to access to a wireless LAN network. it has evolved at the same time technology has been doing it but, what makes WiFi that special is the possibility it offers to users to get access to a WLAN in any place. Before, it has to be done in a static way, having sit in front of a computer that was connected with a cable to the phone line, where it got the access to internet. Now, thanks to the advances engineers have made, it is possible to depend on a small device that is usually password protected, but may be open, which allows any device within its range to access the resources of the WLAN network.

The WiFi Alliance defines Wi-Fi as any "wireless local area network". However, the term "Wi-Fi" has been adopted as an English synonym for “WLAN”. It is because for users the word WiFi is easier to pronounce and thanks to it, "Wi-Fi" is a current trademark of the Wi-Fi Alliance. Actually, the "Wi-Fi Certified" trademark can only be used by Wi-Fi products that successfully complete Wi-Fi Alliance interoperability certification testing.

As this new technology allows people to get access to WLAN from different location within the range of the device, new devices has been created thanks to it. For example, new cell phones, better known as smartphones, emerged after the WiFi invention. Cell phones were before used for making and receiving calls but after WiFi invention, phones became into an everyday tool that allows people to get immediate access to e-mail accounts, browsers and social networks. So that, people are in touch easier and information is available in real time.

Social networks has also evolved thanks to WiFi browsers’ invention. Previous social network allowed people to share information and have new friends but since people were not in front of a computer (the only source to get access to them) information people shared was not up-to-date. Now, people’s posts, comments, photos, videos are been shared in real time and their followers or friends (the name depends on the social network) can know if they are in an airport or having a meal in some restaurant. Devices which can use Wi-Fi technology include personal computers, video-game consoles, smartphones,digital cameras, tablet computers and digital audio players as well as printing devices that have the option of sending information wirelessly to another device, both connected to the local network, in order to print a document.
WiFi is a tool that not only has revolutionised the way people communicate but also the way societies behave. Although the discussion here is quite extensive and different sectors have different points of view, there is no discussion that the idea of having access to websites everywhere you are have change people’s habits as well as cities’ urban design.

The potential for WiFi is endless. For example, police can already track criminals in an instant via mugshots being sent over a device, public can be well informed, warned or alerted about unusual situations via Twitter or through the official websites of government institutions or mass media. Or,in healthcare establishments it is possible to notice many major advances using WiFi, such as way-finding tools to get patients to the right location, opportunity to receive feedback on services, information on waiting times, monitoring use of resources around a hospital building and so on.

An enterprising move or wave comes from the plans to ‘connect’ whole cities. The benefits of creating a WiFi solution for whole cities at once clearly is an attractive proposition for both city managers and citizens. For the city it may improve lifestyles. Children now can get access to information that previously were available in books only. They can also be involved in foreign language learning easier that time ago because several companies have designed their teaching programs via Skype and some free platforms where people guide their learning process in the way that better fit for them. Plus, the possibility of working at home does not seem weird because some companies just need their employees have internet access and that’s all, they are hired. In this way, cities reduce their traffic because some people do not need to go out for working, they are doing it from home.

Nevertheless, it has to be taken into consideration they way people is using in a massive way devices that pollutes. This is the most remarkable issue WiFi era has bring up. Global Warming has been accelerated since people acquire and use different WiFi devices.
