This is the distance that you can measure between two of the highest points in a radio wave, which can range anywhere from 100 meters to 1 centimeter depending on the radio wave you’re observing. This is the count of how many electromagnetic waves pass through a given point every second, and is measured in Hertz. On this electromagnetic spectrum, you can measure and classify radio waves that are used in Wifi, Bluetooth, and other applications in one of two ways: Here’s a great visual for how the electromagnetic spectrum is organized, starting with low frequency and low wavelength on the left.

These waves can all defy even the toughest physical barriers, transmitting data, video, audio and more through the vacuum of space at the speed of light. As we’ve covered in our past blogs in the Wireless Electronic Basics Series, radio waves are but one of many waves in the electromagnetic spectrum, which includes other family members like x-rays, gamma rays, infrared rays, and more. Sharing a Common Foundationīefore we even dive into the differences between WiFi and Bluetooth, it’s important to note that both of these technologies share a common foundation in the wireless electronics family through their use of radio waves. But how exactly do these two technologies work that we rely on so heavily today, and how do you know which one to use in your first project? Let’s find out. While there are many ways to communicate wirelessly, the two kings of the wireless world deserve some attention in your list – WiFi and Bluetooth. Planning to start your first electronics design project? Chances are you’ll be including some kind of wireless functionality to communicate with the web or other devices.
