The present document is part 1 of a multi-part deliverable covering the Wideband Transmission systems; Data trans
21、mission equipment operating in the 2,4 GHz ISM band and using spread spectrum modulation techniques, as identified below: Part 1: Part 2: “Technical characteristics and test conditions“; “Harmonized EN covering essential requirements under article 3.2 of the R - - - - - aggregate bit rates in excess
22、 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
23、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 TM. The equipment offered for testing may be used in fixed, mobile or portable applications,
24、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
25、, 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 andor antenna connectors. CEPT/ERC Recommendation 70-03 (annex 3) i defines the total power and power dens
26、ity 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 d
27、escribes 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) i specifies that spread spectrum modula
28、tion 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 measure
29、ments 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, equi
30、pment 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 Tele
31、phone Network (PSTN) andor other Public Data Networks (PDN).
