A logistics company employs wireless scanning systems to manage its inventory in a large warehouse. The company needs a technology that can quickly identify products without requiring line-of-sight scanning. Which wireless technology would be BEST suited for these requirements?
Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. Because the tag's response is received via radio waves, the reader does not need a clear line of sight, allowing items to be scanned even when they are stacked or obscured-ideal for warehouse operations. Near Field Communication (NFC) is a subset of RFID but is limited to a few centimeters of range, making it unsuitable for this scenario. Bluetooth is designed for short-range personal area networking and is not optimized for bulk item identification. Wi-Fi provides general network connectivity but is not designed for object tracking.
