Pushing 2.4 GHz Wi-Fi to the limits. April 8, 2019 by James Introduction For this project, we aim to answer a simple question: given an ideal environment, how far can you push the range of Wi-Fi connectivity? To test this, we set out with the goal to control a robot as far away as possible using Wi-Fi to transmit commands from a laptop to a Phidget SBC4 . Before we could start, though, we had to do some research. Background Research Some Definitions To get a handle on our main question, we need to establish some background. Wireless communications, such as Wi-Fi, rely on transmitting radio waves at a specific frequency in specific patterns. These patterns are then picked up by a receiving antenna, and translated to usable data. In order for the receiver to understand the incoming signal, it must be strong and clear enough to be distinguished from background noise.…
