Monitor mode, or RFMON (Radio Frequency MONitor) mode, allows a computer with a wireless network interface controller (WNIC) to monitor all traffic received on a wireless channel. Unlike promiscuous mode , which is also used for packet sniffing , monitor mode allows packets to be captured without having to associate with an access point or ad ...
Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder called a tag, a radio receiver , and a transmitter .

There is a wide variety of systems concepts and designs to provide real-time locating. [7] Active radio frequency identification (Active RFID) Active radio frequency identification - infrared hybrid (Active RFID-IR) Infrared (IR) Optical locating [8] [9] Low-frequency signpost identification; Semi-active radio frequency identification (semi ...
The specifications of a RF monitor determines the work environment where could be applicable. Wideband RF monitors can be used at a broader variety of base station sites than for example a narrowband, cellular RF monitor which is designed only to be used in the mobile telephone- and data networks. IEEE Std C95.3 states that "In the region ...
A scanning radio will sequentially monitor multiple programmed channels, or scan between user defined frequency limits and user defined frequency steps. The scanner will stop on an active frequency strong enough to break the radio's squelch setting and resume scanning other frequencies when that activity ceases.
