The present document is part 1 of a multi-part deliverable covering short range devices as identified below: Part 1: “Communications applications“; Part 2: “Ground and Wall Probing Radar application
20、s“. Introduction Ultra-Wideband is a new emerging SRD technology with potential benefits for consumers and businesses, including security applications. UWB technology is undergoing rapid development for a variety of commercial and industrial applications on a global basis. The present document (Part
21、 1 of TR 101 994) covers UWB communication equipment which is expected to operate between 3,1 GHz and 10,6 GHz with a very high bandwidth and a very low radiated power density. The report includes necessary information to support the co-operation under the MoU between ETSI and the Electronic Communi
22、cations Committee (ECC) of the European Conference of Post and Telecommunications Administrations (CEPT) for amending the ERC Recommendation 70-03. The technical characteristics of short range Ground, Wall, and Through-wall Probing Radars using UWB- technology will be covered in part 2 of TR 101 994

33、a given time window isochronous: isochronous transmission transmits asynchronous data over a synchronous data link necessary bandwidth: width of the frequency band which is just sufficient to ensure the transmission of information at the rate and with the quality required under specified conditions
34、NOTE: The definitions (such as Occupied bandwidth, Necessary Bandwidth, etc.) related to UWB are currently under study in CEPT and ITU-R Recommendation TG 1-8 2. Upon completion of this work ETSI will be in a position to update this definition if necessary. Therefore for the time being this definiti
35、on is not to be added to any ETSI definition database. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: AC3 type of audio application CDMA Code Division Multiple Access CE Consumer Electronics CEPT European Conference of Post and Telecommunications admin

NOTE 3:
39、 Data rate limited by mobile phone connection. Due to the high bandwidth UWB is potentially able to transmit very high data rates. UWB systems offer, in contrast to many traditional narrow bandwidth RF systems, an excellent immunity to multi-path interference. Therefore, the requirement for a margin
40、 in the RF link budget is substantially less. Additionally, UWB receivers offer an excellent immunity to interference from other radio systems due to a very high spreading and processing gain. UWB technology is a technical platform for SRD applications for high bit rate communications. The UWB indus
41、try expects it to be implemented by relatively low cost integrated circuits. UWB communication devices have intentional emissions over a wide frequency range and are for widespread use. All the relevant activity factors as well as realistic deployment scenarios and their impact on total aggregation
42、effects should be considered when calculating the total aggregate interference. The proposed necessary bandwidth for communications will fall within the range 3,1 GHz to 10,6 GHz. Emissions outside this range can be attenuated via filters and pulse shaping techniques that are still evolving. The UWB
43、 industry within ETSI proposes in-band transmit power density limit which corresponds to the provisional policy 7 which the FCC has adopted. The aim of the present document is to ask CEPT-ECC to perform the relevant studies to determine whether the above in-band limit is appropriate to protect the o
44、ther radio services in the band and to propose a more adequate value if necessary. The present document does not propose any values outside this frequency band and asks CEPT-ECC to assess which mask (inside and outside the band) will be the most appropriate to ensure that all the radio services insi
45、de and outside the band are fully protected from UWB wanted and unwanted emissions. CEPT is therefore asked to propose an adequate mask and all other practical measures to ensure the protection of all other radio services in and outside the band 3,1 GHz to 10,6 GHz. 4.1 Status of the present documen
46、t Version 1.0.0 had been approved by ERM TG31A and submitted to ERM RM # 25 for approval. Version 1.1.1_1.0.5 was the result of the revision by ERM RM#25 (green text have been reviewed and agreed). That version was sent for a two-week consultation period within ETSI (first deadline 16thof September
47、2003, 16:00). Several comments from other ETSI members had been received and discussed at ERM TG31A#6. The version 1.1.1_1.0.6 is the result of the revision by ERM TG31A. In view of the strong disagreement of TG31A with many comments made during the consultation, version 1.1.1_1.1.1 was prepared by
48、WG ERM RM Secretary to try to consolidate a text acceptable for all parties. This text was offered for a further consultation until 17thof October 2003. Version 1.1.1_1.2.2 was prepared by WG ERM RM Secretary to be presented to TC ERM#21 on the 29thof October for approval for publication. ETSI ETSI
