An RF (radio frequency) wave is a wave that comes from radiation from an electrified uncompensated circuit. This radiation creates a detectable signal that can be picked up by an antenna. This is the most basic form of long range telo-communication, and it is used in virtually all systems that connect wirelessly to some other system. In the case of an RFID system, it is used to communicate between a tag and scanner.
An RFID system consists of three major parts: a transmitter, a transponder, and a transceiver. These parts work together to send, modulate, and receive an RF signal. An RFID transmitter is a part of the scanner/interrogator and sends out RF signals at a given frequency. This can be done omnidirectionally or through a directional antenna. The signal transponder, also commonly referred to as the RFID tag, is a small chip that will attach to the outside of a gun, and it will receive and transmit a message. The RFID transceiver receives and decodes the modulated signal, turning it into readable binary.
All these parts work together to wirelessly send and receive a message, which in the case of Vigilance Safety, will activate an emergency response when triggered.
