Introduction

This Report sets out common technical and non-technical parameters for short-range radiocommunication devices (SRDs) and widely recognized approaches for managing their use on a national basis. When using this Report it should be remembered that it represents the most widely accepted views but it should not be assumed that all given parameters are accepted in all countries.

It should also be remembered that the pattern of radio use is not static. It is continuously evolving to reflect the many changes that are taking place in the radio environment; particularly in the field of technology. Radio parameters must reflect these changes and the views set out in this Report are therefore subject to periodic review.

Moreover, almost all administrations still have national regulations. For these reasons, those wishing to develop or market SRDs based on this Report are advised to contact the relevant national administration to verify that the position set out herein applies.

SRDs are used virtually everywhere. For example, data collection with auto identification systems or item management in warehousing, retail and logistic systems, baby monitors, garage door openers, wireless home data telemetry and/or security systems, keyless automobile entry systems and hundreds of other types of common electronic equipment rely on such transmitters to function. At any time of day, most people are within a few metres of consumer products that use SRDs.

SRDs operate on a variety of frequencies. They must share these frequencies with other radio applications and are generally prohibited from causing harmful interference to or claiming protection from those radio applications. If an SRD does cause interference to authorized radiocommunications, even if the device complies with all of the technical standards and equipment authorization requirements in the national rules, then its operator will be required to cease operation, at least until the interference problem is solved.

However, some national administrations may establish radiocommunication services, using SRDs, whose importance to the public requires that these devices be protected to some degree from harmful interference, without any adverse effect on other administrations. One example for this kind of arrangement is the ultra low power active medical implant communication device as defined below, which is governed by national regulations.

This Report has two annexes. Annex 1 contains technical parameters of several types of additional applications. Annex 2 provides information on national/regional rules which contain technical and operational parameters and spectrum use: those are given in the Appendices to Annex 2.
