The smartphone and the internet we use today wouldnt have been possible without wireless communication technologies such as WiFi It uses radio waves to transmit data between devices and a WiFi access point WiFi has become increasingly popular in recent years WiFi Access Point: is connected to the internet and sends and receives data to and from other devices using radio waves. Wireless Network Interface Card (NIC): Devices that connect to the WiFi network interface card (NIC)
The Impact of Wi-Fi on the World: Increased Connectivity, Improved Education, and Greater Innovation Wi-Fi The smartphone and the internet we use today wouldn't have been possible without wireless communication technologies such as Wi-Fi It uses radio waves to transmit data between devices and a Wi-Fi access point Wi-Fi has become increasingly popular in recent years How Wi-Fi Works Wi-Fi Access Point: is connected to the internet and sends and receives data to and from other devices using radio waves Wireless Network Interface Card (NIC): Devices that connect to the Wi-Fi network interface card (NIC) How Wi-Fi Works Authentication: By providing the correct password or security key Radio Waves: Radio waves to communicate with the Wi-Fi access point (2.4 or GHz) How Wi-Fi Works Data Transmission: The device and the access point use a protocol called the Wi-Fi protocol to transmit data between them This protocol includes rules for how data should be transmitted, how devices should be authenticated, and how interference should be managed How Wi-Fi Works Encryption: To ensure that data transmitted over the Wi-Fi network is secure, it is encrypted using a protocol such as WPA2 This encryption makes it difficult for hackers to intercept and read the data Range: The range of a Wi-Fi network depends on a variety of factors, including the strength of the radio waves, the location of the access point, and any obstacles or interference that might be present The Inventor of Wi-Fi In 1990s if you wanted to "surf" the internet at home, you had to chain yourself to a network cable like it was an extension cord Wi-Fi was invented and released for consumer use Wi-Fi technology was first developed in the 1990s by a group of researchers at the Australian government agency CSIRO, led by Dr John O'Sullivan 1990s -They were attempting to find a way to use radio waves to transmit data over short distances, and eventually came up with a way to so using a technique called "spread-spectrum" technology -This breakthrough allowed for the development of the first Wi-Fi standards, which were released in the late 1990s -With Wi-Fi, people can access the internet without being tethered to a physical cable, allowing for greater freedom and flexibility in how they use technology 10 How Wi-Fi Change the world - Has become ubiquitous in many areas of modern life - In many public spaces - Has gotten progressively faster and found its way into computers, mobile devices and even cars 11 Increased Connectivity - Has made easier to connect to the internet anywhere - Stay in touch - Access information, and work remotely 12 Improved Education - Help to democratize access to education - Making to access online courses and educational resources 13 Enhanced Productivity - Has enabled people to work from anywhere - Making easier for businesses to operate remotely and improving overall productivity 14 Greater Innovation - Has enabled the development of new technologies and services 15 Increased Economic Opportunity - Has created new economic opportunities, particularly in developing countries where access to the internet can help to spur economic growth and development 16 -Wi-Fi has had a profound impact on the world, transforming the way people connect to the internet and changing the way we live and work In -Wi-Fi has increased connectivity, allowing people conclusion to stay in touch with friends and family, access information, and work remotely -It has improved education by democratizing access to educational resources and online courses 17 WI-FI -Wi-Fi has also enabled people to work from anywhere, making it easier for businesses to operate remotely and improving overall productivity -Additionally, Wi-Fi has created new economic opportunities, particularly in developing countries where access to the internet can help to spur economic growth and development -With continued innovation and investment, Wi-Fi will undoubtedly continue to play a key role in shaping the future of technology and society, bringing people closer together and facilitating the exchange of information and ideas on a global scale 18 THANK YOU FOR LISTENING!!! ... encryption makes it difficult for hackers to intercept and read the data Range: The range of a Wi-Fi network depends on a variety of factors, including the strength of the radio waves, the location of. .. access to the internet can help to spur economic growth and development 16 -Wi-Fi has had a profound impact on the world, transforming the way people connect to the internet and changing the way... we live and work In -Wi-Fi has increased connectivity, allowing people conclusion to stay in touch with friends and family, access information, and work remotely -It has improved education by democratizing
