Improved Education, and Greater 2TATC28.A3 Innovation The smartphone and the internet we use today wouldn't have been possible without wireless communication technologies such as Wi-Fi Wi-Fi, short for Wireless Fidelity It uses radio waves to transmit data between devices and a Wi-Fi access point, which is typically a wireless router that is connected to the internet Wi-Fi has become increasingly popular in recent years, and is now widely available in many public spaces such as airports, coffee shops, and hotels It has also become a common feature in many homes and businesses, allowing people to connect to the internet wirelessly from multiple devices Wi-Fi offers many benefits, including increased connectivity, improved education, enhanced productivity, and greater innovation With continued innovation and investment, Wi-Fi is expected to play a key role in shaping the future of technology and society How Wi-Fi Works Wi-Fi is a type of wireless networking technology that uses radio waves to transmit data between devices Here's a basic overview of how Wi-Fi works: Wi-Fi Access Point: A Wi-Fi access point, also known as a wireless router, 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, such as laptops, smartphones, or tablets, have a wireless network interface card (NIC) installed This card allows the device to communicate with the Wi-Fi access point Authentication: Before a device can connect to a Wi-Fi network, it must authenticate itself by providing the correct password or security key 2TATC28.A3 Radio Waves: Once a device is authenticated, it uses radio waves to communicate with the Wi-Fi access point The access point uses a specific frequency range, typically 2.4 or GHz, to transmit data 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 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 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 How Wi-Fi Change the world Since then, Wi-Fi has become ubiquitous in many areas of modern life From homes and offices to airports and coffee shops, Wi-Fi networks are now available in many public spaces, allowing people to stay connected to the internet wherever they go Over the years, Wi-Fi's gotten progressively faster and found its way into computers, mobile devices and even cars Wi-Fi is so essential to our personal and professional lives today that it's almost unheard of to be in a home or public place that doesn't have it The impact of Wi-Fi on the world has been enormous Here are just a few of the ways in which Wi-Fi has changed the world: 2TATC28.A3 Increased Connectivity: Wi-Fi has made it easier for people to connect to the internet from virtually anywhere, allowing them to stay in touch with friends and family, access information, and work remotely Improved Education: Wi-Fi has helped to democratize access to education, making it easier for people to access online courses and educational resources from anywhere in the world Enhanced Productivity: Wi-Fi has enabled people to work from anywhere, making it easier for businesses to operate remotely and improving overall productivity Greater Innovation: Wi-Fi has enabled the development of new technologies and services, from smartphones and tablets to streaming video and online gaming Increased Economic Opportunity: Wi-Fi has created new economic opportunities, particularly in developing countries where access to the internet can help to spur economic growth and development In conclusion, 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 Wi-Fi has increased connectivity, allowing people 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 Wi-Fi has also enabled people to work from anywhere, making
