Frequency Tina RFID Tag hman tlanglawn ber berte chu engte nge ni?
Frequency hian RFID ah hian engkim a tichiang vek. Read distance, data capacity, environmental performance, unit khata senso-a zawng zawng hi electromagnetic spectrum-a tag a thutna hmun atanga lo chhuak vek a ni. Kum 2006 aṭanga access control, livestock management, leh payment application hrang hranga tag maktaduai tam tak thawn chhuah a nih hnuah, a pattern chu a chiang hle.
Commercial RFID deployment-ah hian frequency band pathum a thunun a, chungte chu: low frequency 125-134.2 kHz, high frequency 13.56 MHz, leh ultra-high frequency 860-960 MHz inkar. Band tin hian chip bik an nei a, chu chu industry standard a lo ni ta a, eng tag nge khawiah nge hnathawh tih hriatthiamna hian compatibility failure man to tak tak a veng thei a ni.
