RFID devices operating at UHF frequencies are allowed for operation in the Industrial, Scientific, and Medical (ISM) bands under conditions defined in FCC part 15 rules, section 15.247.

An RFID system consists of a tiny radio transponder called a tag, a radio receiver, and a transmitter.RFID devices operating at UHF frequencies are allowed for operation in the Industrial, Scientific, and Medical (ISM) bands under conditions defined in FCC part 15 rules, section 15.247. Section 15.247 defines operation within the bands 902–928 .

As a general principle, most RFID systems use the so-called ISM bands (Industrial, Scientific, and Medical Band) in order to avoid cross-talk of radio systems and ensure reliable data information exchange. UHF RFID operates in the industrial, scientific, and medical (ISM) unlicensed band and shares the spectrum with other devices. To mitigate potential interference, FCC mandates the use of frequency hopping.

These frequency bands are now known as the ISM bands, or the Industrial Scientific and Medical Bands. UHF RFID technology uses two main frequency ranges — 902-928 MHz and 865-868 MHz; however, a few countries have adopted either multiple bands or unique ranges on the ISM standard.

Our comprehensive evaluation shows that TiFi allows WiFi receivers to identify UHF RFID tags within the range of 2 m and with a median goodput of 95%, which is comparable to today’s mobile RFID readers.We propose a low-cost, easy-to-fabricate, and pattern reconfigurable UHF (Ultra High Frequency) RFID reader antenna in the RFID ISM band (902-928 MHz in the US). The antenna offers a 54 MHz bandwidth (890 - 944 MHz) and 8.9 dBi maximum gain.

Passive RFID applications are in place in several ISM frequency bands. The three most important bands are: LF (100–135 kHz), HF (13.56 MHz) and UHF (860–960 MHz). Which band is selected depends on the application, on the national radio.Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects.

This work presents the development and design of a loop antenna for dual-band RFID applications at 860 – 960 MHz and 2.4 GHz. The antenna is compact and has a loop structure with vias to enhance the radiating efficiency.This paper investigates the effects of RF interference be-tween a passive UHF RFID system and a communications sys-tem sharing the 902 MHz to 928 MHz industrial, scientific and medical (ISM) band.Our comprehensive evaluation shows that TiFi allows WiFi receivers to identify UHF RFID tags within the range of 2 m and with a median goodput of 95%, which is comparable to today’s mobile RFID readers.We propose a low-cost, easy-to-fabricate, and pattern reconfigurable UHF (Ultra High Frequency) RFID reader antenna in the RFID ISM band (902-928 MHz in the US).
