RFID Technology: Spectrum used for RFID…Sequel II

Nowadays we are hearing news about 2G SPECTRUM Ghotala (Fraud). The biggest fraud in the history of India. It is under investigation!!! For RFID also some of bands (Spectrum) are used for its usage J but there would no Ghotala as such.

Last week, basic operation of RFID application and usage were discussed. Many of us were thinking about the frequencies being used in RFID application.

Three frequency ranges are generally distinguished for RFID systems, low, intermediate (medium) and high. The following table summarizes these three frequency ranges, along with the typical system characteristics and examples of major areas of application.

Frequency Band	Characteristics	Typical Applications
Low 100-500kHz	  Short to medium read range   Inexpensive   low reading speed	  Access control   Animal identification   Inventory control   Car immobiliser
HF 10-15MHz	  Short to medium read range   Potentially inexpensive   Medium reading speed	  Access control   Smart cards
UHF 850-950MHz  Ultra High Frequency	  Long read range   High reading speed   Line of sight required   Expensive	  Railroad car monitoring   Toll collection systems

Next week, I will give brief about LF, HF & UHF for better understanding and usage of these spectrums. So Not possible for any Ghotala in RFID usage as government has allocated for RFIDJ.
