The Impact of Wi-Fi on the World: Increased

Connectivity, Improved Education, and

Greater Innovation

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 5 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

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

The Inventor of Wi-Fi

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 do 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

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

- 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

Increased Connectivity

- Has made easier to connect

to the internet anywhere

- Stay in touch

- Access information, and

work remotely

Improved Education

- Help to democratize access to

education

- Making to access online courses

and educational resources

Enhanced Productivity

- Has enabled people to work from

anywhere

- Making easier for businesses to

operate remotely and improving

overall productivity

Greater Innovation

- Has enabled the development of

new technologies and services

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

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 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
