ETSI ETSI EN 300 328-1 V1.3.1 (2001-12) 6 Introduction Wideband radio data transmission systems are rapidly being introduced into a variety of commercial and industrial applications and the technology employed by these systems is still developing. The present document may be used for the assessment of the performance of the equipment. The performance of the equipment submitted for type testing should be representative for the performance of the corresponding production model. In order to avoid any ambiguity in that assessment, the present document contains instructions for the presentation of equipment for type testing purposes where required (clause 4), testing conditions (clause 6) and methods of measurement (clause 7). It is intended to include requirements for multi-radio equipment in the present document, but at this time the technical considerations are still ongoing. Upon completion of this work, the present document will be revised to include these requirements. ETSI intend to recommend to CEPT that the requirement for a minimum aggregate bit rate (250 kbit/s) is removed from the CEPT Recommendation 70-03 (annex 3) [1]. When CEPT have made this decision, the present document will be revised to reflect this decision. SIST EN 300 328-1 V1.3.1:2003
ETSI ETSI EN 300 328-1 V1.3.1 (2001-12) 7 1 Scope The present document covers equipment referred to in CEPT/ERC Recommendation 70-03 (annex 3) [1]. The present document covers the minimum technical characteristics for radio data transmission equipment having the following technical parameters: - wideband radio modulation techniques; - aggregate bit rates in excess of 250 kbits/s; - operation in the 2,4 GHz to 2,4835 GHz Industrial, Scientific and Medical (ISM) band; - effective radiated power of up to -10 dBW (100 mW); - power density of up to -10 dBW (100 mW) per 100 kHz for frequency hopping modulation; - power density of up to -20 dBW (10 mW) per 1 MHz for other forms of spread spectrum modulation. The present document only addresses the transceivers, transmitters and receivers of equipment offered for testing and includes such technologies as IEEE 802.11 [5], HomeRF ™. The equipment offered for testing may be used in fixed, mobile or portable applications, e.g.: - stand-alone radio equipment with or without their own control provisions; - plug-in radio devices intended for use with or within a variety of host systems, e.g. personal computers, hand-held terminals, etc.; - plug-in radio devices intended for use within combined equipment, e.g. cable modems, set-top boxes, access points, etc.; - combined equipment or a combination of a plug-in radio device and a specific type of host equipment. The equipment may be fitted with integral antennae and/or antenna connectors. CEPT/ERC Recommendation 70-03 (annex 3) [1] defines the total power and power density limits for systems using spread spectrum modulation together with a minimum aggregate bit rate of 250 kbit/s. The recommendation does not address the details of these modulation techniques. Therefore, the present document does not cover the design or operation of the equipment being tested but describes a common set of measurements to be applied to various types of such equipment, including those employing Frequency Hopping Spread Spectrum (FHSS) modulation and Direct Sequence Spread Spectrum (DSSS) modulation. CEPT/ERC Recommendation 70-03 (annex 3) [1] specifies that spread spectrum modulation be used and it gives power density values for FHSS and DSSS modulation. The present document specifies the minimum technical parameters of FHSS modulation such that it can be clearly differentiated from other types of modulation, including DSSS modulation. The present document describes measurements for operating frequency range(s), effective radiated power and power density as well as spurious emissions for transmitters and receivers. The measurement methods have been adapted from TR 100 027 [2] where possible. The present document specifies test site characteristics, test conditions, equipment calibration and methods of measurement. The present document is a general standard which may be superseded by specific standards covering specific applications. Additional standards or specifications may be required for equipment such as that intended for connection to the Public Switched Telephone Network (PSTN) and/or other Public Data Networks (PDN).
