How WiFi Works, Part 2


Wireless internet is almost everywhere these days, and many Americans connect and use it without thinking. For residents of rural areas, however, WiFi isn’t always easily accessible or affordable. Clarus Broadband is here to close the gap by introducing fiber optic internet to communities throughout Texas, Oklahoma, and more.

Not only are we dedicated to helping rural residents access high-speed wireless internet, but Clarus Broadband also wants to help people better understand the wonder of this important invisible resource. In this blog series, we are discussing how WiFi works. We recommend that you review part one of this series in order to learn how WiFi is transmitted and how the system accommodates multiple signals in one building. Today, in part two of this series, we continue the conversation. Keep reading to learn more, and contact Clarus Broadband today to learn how you can bring a better internet plan to your hometown!

Connecting to Your Device

In order to communicate with your router, a device needs to be fitted with a wireless transmitter. Most devices these days, including smartphones and laptops, already have this built into their design. However, if you are using an older device, then you will need to find an wireless adapter to fit whatever connection ports you have available, such as USB. This will translate the signal sent by your router into information your laptop or cell phone can understand. Some devices simply can’t work with WiFi, like certain smart TVs or disc players, and those devices typically need an ethernet cable to plug in directly to the internet and its stream of information.

Translating the Data

Computers communicate in binary code: a series of zeroes and ones. Your wireless router and the wireless chip in your device both need the ability to translate these digits into radio waves and vice versa in order to connect. Your router receives information in binary through a physical connection, such as its own ethernet cord, and then translates that data into radio waves your device and its wireless transmitter can receive. Your WiFi chip translates binary into the text and images you see as you surf the internet. At the same time, your wireless transmitter is sending information back to the router in radio waves that the router translates back into binary code.

The rate at which your system can do this is what many refer to as your internet speed. Most internet service providers offer a speed measurement in megabits per second (Mbps). One bit equals a one or a zero. A router with a speed of 54 Mbps, for example, can process 54 million ones or zeroes per second. To investigate what kind of speed you need or should expect from your system, we encourage you to explore our series on internet speed!

While many of us take wireless internet for granted, it is a pretty incredible process once you start to learn about it. Here at Clarus Broadband, we believe everyone should have access to the instant connection and communication that comes with high-speed internet, which is why we are campaigning to bring fiber optics to rural Texas. All we need are people like you! Help us bring fiber optic internet to your community, and contact Clarus Broadband today to learn more!
