1 doc.: IEEE c Submission Kai Siwiak (TimeDerivative, Inc.) July 2005 Slide 1 Project: IEEE P 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:[ ], FAX: [ - ], Re: [ - ] Abstract:[ISM frequencies are defined between 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 P It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein. Release:The contributor acknowledges and accepts that this contribution becomes the property of IEEE and may be made publicly available by P

2 doc.: IEEE c 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 and 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: – kHz (centre frequency 6780 kHz) – MHz (centre frequency MHz) in Region 1 except in the countries mentioned in RR No – GHz (centre frequency GHz) – GHz (centre frequency GHz) – 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 : – kHz (centre frequency kHz) – kHz (centre frequency kHz) – MHz (centre frequency MHz) – MHz in Region 2 (centre frequency 915 MHz) – MHz (centre frequency 2450 MHz) – MHz (centre frequency 5800 MHz) – GHz (centre frequency GHz)
