Wireless Fidelity: Meaning, Application & Future

Needless to say that there is almost nobody who hasn't heard about Wireless Fidelity, or simply WiFi. But not many knew its application and the future of WiFi. Check out our detailed explainer where we talk about the same, let's get started :)
Introduction
Wi-Fi stands for "Wireless Fidelity." It refers to a wireless networking technology that allows devices to connect to the internet or to other devices without the need for physical cables or wires. Wi-Fi works by using radio waves to transmit data between devices within a certain range. It is a popular technology for connecting devices like smartphones, laptops, and tablets to the internet, as well as for creating wireless networks in homes, businesses, and public spaces.
How does it work?
-Wi-Fi works by using radio waves to transmit data between a wireless router and a device, such as a laptop, smartphone, or tablet. The router is connected to the internet through a wired connection, such as a cable or DSL line.
-When a device wants to connect to the internet via Wi-Fi, it sends a signal to the router. The router then sends a signal back to the device to establish a connection and exchange data. This exchange of data happens through a wireless network adapter, which is built into most modern devices.
-The router and the device communicate using a set of protocols, or rules, that govern how data is transmitted over the wireless network. The most common Wi-Fi protocol is called IEEE 802.11, and it is supported by most modern devices.
-To ensure the secure transmission of data, Wi-Fi networks can use various encryption methods, such as WPA2 or WPA3. These encryption methods encode the data being transmitted so that it can only be read by the intended recipient.
What does the future look like?
The future of Wi-Fi is likely to be shaped by several technological trends and advancements that are already underway or are expected to emerge in the coming years. Here are a few key trends that may shape the future of Wi-Fi:
-Wi-Fi 6E: The latest iteration of Wi-Fi, known as Wi-Fi 6E, extends the capabilities of Wi-Fi 6 to the 6 GHz frequency band. This allows for faster and more reliable connections with less interference from other wireless devices.
-Internet of Things (IoT): As more devices become connected to the internet, the demand for Wi-Fi networks that can handle large numbers of devices simultaneously is likely to increase. Wi-Fi 6 and 6E have features designed to support IoT devices, such as reduced power consumption and improved security.
-Mesh networks: Mesh networks use multiple Wi-Fi access points to create a seamless network that can cover a larger area with better coverage and fewer dead zones. Mesh networks are becoming increasingly popular in homes and businesses, and are likely to become even more widespread in the future.
-Wi-Fi 7: The next generation of Wi-Fi, known as Wi-Fi 7, is currently in development and is expected to offer even faster speeds, lower latency, and better reliability than Wi-Fi 6 and 6E.
-5G and Wi-Fi integration: As 5G networks become more widespread, there is potential for Wi-Fi and 5G to be integrated into a single network, offering seamless connectivity and improved performance for mobile devices.
Summary
Overall, Wi-Fi provides a convenient and reliable way to connect devices to the internet and to each other without the need for physical cables or wires. The future of Wi-Fi is likely to be shaped by advancements in technology and changes in the way we use wireless networks. Wi-Fi will continue to play a critical role in connecting devices and enabling new applications and services and will remain a key technology for years to come.
