Episode 32: Bluetooth, NFC, RFID, and Long-Range Wireless

This episode explores a set of wireless technologies that extend beyond traditional Wi-Fi, many of which play crucial roles in mobile and IoT environments. We begin with Bluetooth—covering pairing modes, version updates, range limitations, and bandwidth considerations. Then we move to Near Field Communication, or N F C, which is used for short-range authentication, payments, and device pairing with just a tap.

We also cover R F I D systems, used in access control and asset tracking, and examine other long-range wireless technologies like L T E and LoRa that enable wide-area IoT communication. These technologies often appear on the exam in port, protocol, or device interaction questions. By the end of this episode, you'll have a strong understanding of how short- and long-range wireless technologies differ in scope, range, and function. Brought to you by BareMetalCyber.com.
