Latest updates are available on the ETSI Web server (http:/webapp.etsi.org/IPR/home.asp). Pursuant to the ETSI IPR Policy, no investigation, includi

No guarantee can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web server) which are, or may be, or may become, essential to the present document. Foreword This Harmonized European Standard (Tel
4、ecommunications series) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). The present document has been produced by ETSI in response to a mandate from the European Commission issued under Council Directive 98/34/EC i.2 (as amended) laying d
5、own a procedure for the provision of information in the field of technical standards and regulations. The present document is intended to become a Harmonized Standard, the reference of which will be published in the Official Journal of the European Communities referencing the Directive 1999/5/EC i.3
6、 of the European Parliament and of the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual recognition of their conformity (“the R and 2) RF carrier based technologies. The following clauses give a brief overview of these UWB technologies and their ass
7、ociated modulation techniques. Impulse technology Impulse derived UWB technology consists of a series of impulses created from a dc voltage step whose rise time can be modified to provide the maximum useful number of spectral emission frequencies. This derived impulse can then be suitably modified b
8、y the use of filters to locate the resulting waveform within a specific frequency spectrum range. This filter can be a standalone filter or incorporated into an antenna design to reduce emissions outside the designated frequency spectrum. Modulation techniques include pulse positioning in time, puls
9、e suppression and other techniques to convey information. The transmitted energy is summed at the receiver to reproduce the transmitted pulse. This technology is suitable for direct and non-direct line of sight communications, any reflected or time delayed emissions being suppressed by the receiver
10、input circuits. RF carrier based technology RF carrier based UWB technology is based upon classical radio carrier technology suitably modulated by a baseband modulating process. The modulating process must produce a bandwidth in excess of 50 MHz to be defined as UWB. Different modulating processes a
11、re used to transmit the data information to the receiver and can consist of a series of single hopping frequencies or multi-tone carriers. This technology can be used for both direct and non-direct line of sight communications, any reflected or time delayed emissions being suppressed by the receiver
12、 input circuits. Test and measurement limitations The ERA report 2006-0713 i.9 has shown that there are practical limitations on measurements of RF radiated emissions. The minimum radiated levels that can be practically measured in the lower GHz frequency range by using a radiated measurement setup
13、with a horn antenna and pre-amplifier are typically in the range of about -70 dBm/MHz to -75 dBm/MHz (e.i.r.p) to have sufficient confidence in the measured result (i.e. UWB signal should be at least 6 dB above the noise floor of the spectrum analyser and the measurement is performed under far-field
14、 conditions at a one meter distance). For equipment that have dedicated detachable antennas and provide a 50 ohm antenna port for testing, conducted measurements can be made provided that suitable antenna calibrations can be provided. In the present document, test suites for conducted measurements a
15、re only provided for DAA conformance measurements. Transmitter emissions of the radio device are expected to be measured using the radiated measurement setup with the exception of UWB devices which are intended to operate at a mean power spectral density of -70 dBm/MHz or less, then a conducted test
16、 procedure can be used. ETSI ETSI EN 302 065 V1.2.1 (2010-10) 8For integrated antenna equipment, previous ETSI testing standards have allowed equipment modification to provide a 50 ohm test adaptor to be added to provide the necessary test port. However, UWB integral equipment and particularly impul
17、se based technology does not use classical radio techniques and as such is unlikely to have matched 50 ohm antenna port impedances. The present document therefore recognizes these difficulties and provides a series of test methods suitable for the different UWB technologies. ETSI ETSI EN 302 065 V1.
