July 2005 Slide 1 Project: IEEE P802.15 Working Group for Wireless Personal Area Networks (WPANs) Submission Title: [ISM-Frequencies] Date Submitted: [21 July, 2005] Source: [Kazimierz Kai Siwiak] Company [TimeDerivative, Inc.] Address [PO Box 2088, Coral Springs, FL, USA] Voice:[+1 954-937-3288], FAX: [ - ], E-Mail:[email@example.com] Re: [ - ] Abstract:[ISM frequencies are defined between 6.765 MHz and 246 GHz.] Purpose:[Informative: Use of the term ISM band should be specific when used in IEEE802 documents. The term generally includes a large list of frequencies.] Notice:This document has been prepared to assist the IEEE P802.15.

doc.: IEEE 15-05-0459-01-003c Submission Kai Siwiak (TimeDerivative, Inc.) July 2005 Slide 2 ITU list of ISM Frequencies The ITU lists frequency bands for industrial, scientific and medical (ISM) applications. The international Table of Frequency Allocations, which is contained in Article 5 of the Radio Regulations (Volume 1), specifies some frequency bands that may be made available for ISM applications (see RR Nos. 5.138 and 5.150 reproduced below): RR-5.138: The following bands are designated for ISM applications. The use of these frequency bands for ISM applications shall be subject to special authorization by the administration concerned, in agreement with other administrations whose radiocommunication services might be affected. In applying this provision, administrations shall have due regard to the latest relevant ITU-R Recommendations: –6765-6795 kHz (centre frequency 6780 kHz) –433.05-434.79 MHz (centre frequency 433.92 MHz) in Region 1 except in the countries mentioned in RR No. 5.280 –61-61.5 GHz (centre frequency 61.25 GHz) –122-123 GHz (centre frequency 122.5 GHz) –244-246 GHz (centre frequency 245 GHz) RR-5.150: The following bands are also designated for industrial, scientific and medical (ISM) applications. Radiocommunication services operating within these bands must accept harmful interference, which may be caused by these applications. ISM equipment operating in these bands is subject to the provisions of RR No. 15.13: –13553-13567 kHz (centre frequency 13560 kHz) –26957-27283 kHz (centre frequency 27120 kHz) –40.66-40.70 MHz (centre frequency 40.68 MHz) –902-928 MHz in Region 2 (centre frequency 915 MHz) –2400-2500 MHz (centre frequency 2450 MHz) –5725-5875 MHz (centre frequency 5800 MHz) –24-24.25 GHz (centre frequency 24.125 GHz)
