2、commendation proposed by the Working Group “Radio Regulatory” (RR) Text of the Recommendation adopted by the “Eiuopean Radiocoinminiiicntioiis Committee” (ERC). “The European Conference of Postal and Telecommunications Administrations, considering a) that Digital Short-Range Radio (DSRR) equipment i
3、ntended to provide voice and/or data communication operated in the frequency bands 933-935/888-890 MHz, will be available for business and/or general purpose, bj that such equipment can meet the demands for short-range radiocommunications and in this way can contribute to the diminishing of the cong
4、estion in the other frequency bands allocated to the non-public land mobile service, c) that it would be desirable for Administrations to have common regulations at their disposal in order to control the use, the type approval, the marking and the free circulation of the DSRR equipment, d) that the
5、technical characteristics and the methods of measurement for the DSRR equipment are harmonized and in- cluded in an European Telecommunication Standard, e) that the clear identification of DSRR equipment would facilitate free circulation of this type of equipment, O recommends 1. that CEPT member Ad
6、ministrations allow DSRRequipment complying withETSI standard1-ETS 300 168 for Digital Short-Range Radio, to be used for business and/or general purpose by any person, subject to the common admi- nistrative conditions specified below, 2. that CEPT member Administrations designate the frequency bands
7、 933-935 MHz and 888-890 MHz for use by DSRR equipment in accordance with Recommendation T/R 75-02 E (Note), 3. that Administrations - shall give DSRR-usersthe discretion to communicate with any other DSRR-user; - may, however, in the case of the two-frequency semi-duplex mode of operation, allow us
8、ers to employ the facility available in base or repeater stations to send messages to and/or receive messages from only pre-selected parties, 4. that CEPT member Administrations adopt the rules for authorization of DSRR equipment in conformity with the conditions set out in Annex 1 of this Recommend
9、ation, 5. that CEE member Administrations adopt the rules for free circulation and marking of DSRR equipment in conformity with the conditions set out in Annex 2 of this Recommendation.” Note. In some countries parts of the band 888-890 MHzmay be used for telecommand and telemetry, thus restricting
10、the use of DSRl7. However, in all cases, both control channels 888.6625 MHz and 889.3125 MHz shall be kept free from the use by telecommand and telemetry equipment.

11、3 Annex 1 CONDITIONS FOR THE USE OF DSRR EQUIPMENT DEFINITIONS DSRR system: DSRR is a radiocommunication system in the land mobile service based on a dynamic frequency selection system providing digital short-range radiocommunications for voice and/or data in the frequency bands 933-9351888-890 MHz
12、with a maximum out- put power of 4 W. It can encompass the following stations: a station in the land mobile service intended to be used while carried by a person. a station in the land mobile service mounted in a vehicle and intended to be used while in motion or during halts at unspecified points.
13、a station in the land mobile service installed at a fiied location. a station in the land mobile service installed at a fixed location which is intended to establish radiocommunications between portable and/or mobile stations. Portable DSRR station: Mobile DSRR station: DSRR base station: DSRR repea
14、ter: USE OF THE STATION The DSRR-user may use the equipment for business and/or general radiocommunications and is allowed to select the wanted communication partner as stated in Recommends 3. It shall not be allowed to use the equipment for other purposes, for instance for transmission or retransmi
