How Does WiFi Work Exactly? The Technology Explained
Almost 61 percent of the world’s population uses the internet!
WiFi is an important part of most people’s lives. They use it every day to work, play, and communicate with friends and family around the world.
However, many people don’t know how WiFi works exactly because the technology isn’t as simple as flipping a switch or pressing a button.
In this post, you will learn what WiFi is and find the answer to the question, “How does WiFi work?”
What is WiFi?
WiFi is a technology that allows wireless internet access over radio waves in the ISM band from 2400 to 2483.56 megahertz. It enables communication between fixed and mobile devices, such as computers, printers, or smartphones via wireless LAN.
WiFi was originally created by the company NCR Corporation for people working in their buildings, but it has since been adopted and expanded to cover a large number of devices.
In the early days of wireless networks, WiFi did not have much range or reliability because smartphones were too weak and only had short battery life. Today, however, smartphones and laptops have become more powerful and can support a WiFi connection to devices like printers or projectors.
WiFi Signals Explained
WiFi signals are sent via radio waves. A device that can receive and transmit them is called a wireless router, which needs to be plugged into the wall for power (and access to an Ethernet cable).
There is no voltage in WiFi signals and they do not travel through walls. They use higher frequencies (in the microwave range) to transmit data over short distances, from 100 to 500 meters.
The Role of Routers
Wireless routers connect devices like laptops or smartphones wirelessly using WiFi technology, allowing you to use your laptop without needing any cables attached.
The router sends out WiFi signals to all the different devices connected. Some routers are enhanced with a little antenna called an “external” or “secondary” antenna, which can pick up your signal more easily if it’s having trouble transmitting over longer distances.
Wi-Fi has revolutionized office space and remote work. It is also revolutionizing how businesses can offer customer satisfaction. One way to make customers happy is to have a VBN.
A VBN is a virtual-based network that will give the public access to Wi-Fi in your office for short periods. You can learn how VBN works and then see if it is worth implementing in your business.
The Future of Wi-Fi
You probably use Wi-Fi every day and if you have been wondering, “How does Wi-Fi work?” you now know the answer. Wi-Fi is convenient to use and it makes communicating much easier.
The future of Wi-Fi is unlimited and as different types of electronic devices are invented Wi-Fi has been integrated into them to enable their “smart” functionality.
