Footnotes

US2 In the band 9-490 kHz, electric utilities operate Power Line Carrier (PLC) systems on power transmission lines for communications important to the reliability and security of electric service to the public. These PLC systems operate under the provisions of 47 CFR part 15, or Chapter 8 of the NTIA Manual, on an unprotected and non-interference basis with respect to authorized radio users. Notification of intent to place new or revised radio frequency assignments or PLC frequency uses in the band 9-490 kHz is to be made in accordance with the Rules and Regulations of the FCC and NTIA, and users are urged to minimize potential interference to the extent practicable. This footnote does not provide any allocation status to PLC radio frequency uses.

US18 In the bands 9-14 kHz, 90-110 kHz, 190-415 kHz, 510-535 kHz, and 2700-2900 MHz, navigation aids in the U.S. and its insular areas are normally operated by the Federal Government. However, authorizations may be made by the FCC for non-Federal operations in these bands subject to the conclusion of appropriate arrangements between the FCC and the Federal agencies concerned and upon special showing of need for service which the Federal Government is not yet prepared to render.

Radiofrequency Identification (RFID)
Current Use
9–135 kHz RFID (inductive systems)
An RFID system consists of an interrogator and a transponder, and is used for identification and data capture. RFID systems are used for a very wide range of applications, including:
Highway tolls
Vehicle tracking
Container tracking
Inventory control & theft prevention (often used to prevent shoplifting)
Healthcare (patient & drug tracking)
Passports
ID cards
Building entry
Livestock & pet tracking
and numerous other applications.
RFID tags can be extremely small devices with little or no internal power, which respond to an interrogation by utilizing some of the RF energy imparted by the interrogator; or they can be larger powered units that can be interrogated over larger distances.
The ITU is in the process of attempting to harmonize RFID bands, since RFID systems are used for global commerce. ITU Study Group 1 (Working Party 1B) is drafting a new ITU-R Recommendation on RFID.
ISO/IEC18000 is the principal standard for the RFID air interface.
RFID systems typically operate in ISM and unlicensed bands.
The bands listed below represent the totality of the various bands presently used around the world. The exact bands used in specific countries may vary (and is what the ITU is attempting to harmonize).
