The RFID tag working in the 2.45GHz frequency band has a built-in battery, so the tag itself can rely on the energy of the battery to emit stronger signal waves and transmit longer distances.The transmission distance can be as long as 0-100m.
Each active RFID tag can be used according to the frequency of use, and the service life of the battery is 2-3 years. Active RFID tags are divided into battery-replaceable and non-replaceable battery types. The non-replaceable battery RFID tags are ultrasonically sealed and waterproof. RFID tags with replaceable batteries need to be used in an environment free of moisture.
2.4G active readers are divided into directional readers and omnidirectional readers. The signal wave of the directional reader is transmitted towards the front of the reader. The signal wave of the omnidirectional reader will be transmitted in 360 degrees.
