Can RFID Be Used as a Cable Locator?
Would this technology enable us to identify a specific cable?
Yes, radio frequency identification can be used to locate cables, provided that nothing blocks the handheld RFID reader's signal from reaching the tags. You could buy tags that could hang from different cables and associate the unique serial number in each tag with a specific cable or type of cable. If you needed to locate that cable, you could use a handheld that would beep louder as you moved closer to the tag—the device would detect the signal strength, which would get stronger the closer you were, so it would be easy to identify one tagged cable from another.
