•

Radiofrequency identification (RFID): RFID tags operate at the

frequency bands of LF (120–140 KHz), HF (13.56 MHz), UHF

(868–956 Mhz), and microwave (2.4 GHz). Section 3.13 explains

RFID technology and its applications.

•

Infrared data association (IrDA): IrDA uses frequencies around

100 GHz for short-range data communication.
