4 in accordance with Resolution **95 (Rev.WRC‑03)**, to review the
Resolutions and Recommendations of previous conferences with a view to
their possible revision, replacement or abrogation

# 1 Introduction

The Arab States believe that there is a need to identify new bands for
short-range radiocommunication devices (SRDs), outside those bands
already designated for ISM equipment, but only on the condition that
limits from such devices be specified within the newly identified bands
for worldwide use and/or regional use. They also believe that the
objectives of Resolution 952 (WRC-03) on studies regarding devices using
ultra-wideband technology have been met by ITU‑R.

# 2 Proposals

2.1 The Arab States propose to modify Resolution 63 (Rev.WRC-03).

2.2 The Arab States also propose the suppression of Resolution 952
(Studies regarding devices using ultra-wideband technology).

RESOLUTION 63 (Rev.WRC‑07)

Protection of radiocommunication services against interference\
caused by radiation from short-range radio devices (SRDs)[^1]

The World Radiocommunication Conference (Geneva, 2007),

considering

*a)* that the SRDs, including industrial, scientific and medical (ISM)
equipment, devices using ultra-wideband technologies, radio frequency
identification devices (RFID) generate and use locally radio frequency
energy, whereby outward radiation cannot always be avoided;

*b)* that there is an increasing amount of such devices working on
various frequencies throughout the spectrum;

*c)* that in some cases a considerable part of the energy may be
radiated by an SRD outside its working frequency;

*d)* that the International Special Committee on Radio Interference
(CISPR) has not published any guide for the use of these devices
including ISM, and does not yet fully specify radiation limits for such
devices, nor limit their use to some frequency bands, preferably those
for ISM equipment to protect radiocommunication services, but that
CISPR 11 does not yet fully specify radiation limits for all frequency
bands;

*e)* that some radio services, especially those using low field
strengths, may suffer interference caused by radiation from SRDs, a risk
which is unacceptable particularly in the case of radionavigation or
other safety services;

*f)* that, in order to limit the risks of interference to specified
parts of the spectrum:

-- the preceding Radio Conferences of Atlantic City, 1947, and Geneva,
1959, designated some frequency bands within which the
radiocommunication services must accept harmful interference produced by
ISM equipment;

-- a future WRC might identify bands to be designated for such devices,
but only on the condition that limits of radiation from such devices be
specified within the bands already designated for worldwide use and
outside all the bands designated for ISM equipment,

resolves

that, to ensure that radiocommunication services are adequately
protected, studies are required on the limits to be imposed on the
radiation from SRDs within the frequency bands designated in the Radio
Regulations for this use and outside of those bands,

invites ITU‑R

1 to continue, in collaboration with CISPR, its studies relating to
radiation from SRDs within the frequency bands designated in the Radio
Regulations for this use and outside of those bands in order to ensure
adequate protection of radiocommunication services, with priority being
given to the completion of studies which would permit CISPR to define
limits in radiation from SRDs inside all the bands designated in the
Radio Regulations and outside of those bands for the use of such
devices;

2 to identify, in collaboration with CISPR, or alone, if there is a need
to modify the definition of ISM application.
