19、This Technical Specification (TS) has been produced by ETSI Technical Committee Satellite Earth Stations and Systems (SES). The present document is part 5 of a multi-part deliverable covering the BSM Regenerative Satellite Mesh - A (RSM-A); air interface; Physical layer specification, as identified
20、below: Part 1: “General description“; Part 2: “Frame structure“; Part 3: “Channel coding“; Part 4: “Modulation“; Part 5: “Radio transmission and reception“; Part 6: “Radio link control“; Part 7: “Synchronization“. ETSI ETSI TS 102 188-5 V1.1.2 (2004-07) 6 1 Scope The present document defines the Rad
21、io Frequency (RF) requirements for the Satellite Terminal (ST) transceiver of the Regenerative Satellite Mesh - A (RSM-A); Air interface operating in the Fixed Satellite System (FSS) allocations at Ka-band as follows: ST reception is in the Fixed Satellite Service (FSS) frequency ranges from 17,70 G
22、Hz to 19,70 GHz and from 19,70 GHz to 20,20 GHz; ST transmission is in the frequency ranges allocated to FSS from 27,50 GHz to 29,50 GHz and from 29,50 GHz to 30,00 GHz. Requirements are defined for two categories of parameters: those that are required to provide compatibility between the radio chan
23、nels, connected either to separate or common antennas, that are used in the system. This category also includes parameters providing compatibility with existing systems in the same or adjacent frequency bands; those that define the transmission quality of the system. These requirements apply to all
24、types of ST that transmit a single modulated carrier, including STs with an antenna diameter greater than 1,8 m (or equivalent corresponding aperture). The technical requirements of the present document apply under the environmental profile for operation of the equipment, which shall be declared by
25、the manufacturer. The equipment shall comply with all the technical requirements of the present document at all times when operating within the boundary limits of the declared operational environmental profile. The environmental profile for operation of the equipment shall include the ranges of humi
26、dity, temperature and supply voltage. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
