There’s an urban legend that if you hold a wireless car key up to your face it’ll increase its range.

It sounds crazy, but I want to know if it works. Could I actually increase the range of my wireless car key? If my face works, what else might work? So, I called up the brightest, sharpest minds in Keysight and some of the marketing department and told them whoever could get the best signal improvement wins $100 dollars. We’re measuring power in dBm using a FieldFox. Everyone starts out with an unaided, baseline power measurement. Whoever can improve their signal the most from their key’s baseline wins. The higher the power, the farther the range.

Check out the Keysight FieldFox, which we used for all of these measurements: https://www.keysight.com/us/en/products/network-analyzers/fieldfox-handheld-rf-microwave-analyzers.html
