Operating frequencies for the GMR-2 Ground Terminal (Gateway or NCC) -to-Satellite Terminal (ST) uplinlddownlink are not specified , however, for ease of understanding, the present document describes the requirements for a GMR-2 Ground Terminal-to-Satellite Terminal uplinlddownlink operating in the 3000/6000 MHz C-Band. Requirements are defined for two categories of parameters: a) Those that are required to provide compatibility between the Mobile Earth Station, ground terminal, and satellite channels, connected either to separate or common antennas, that are used in the system. This category also includes parameters providing compatibility with existing systems in adjacent frequency bands; b) Those that define the transmission quality of the system. This standard defines RF characteristics for the Mobile Earth Station (MES), satellite terminal (ST), and ground terminal (GT- Gateway or NCC). Unless otherwise stated, the requirements defined in this standard apply to the full range of environmental conditions specified for the equipment (see Section A.4). 2 Refe re nces The following documents contain provisions which, through reference in this text, constitute provisions of the present document. 0 References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. 0 For a specific reference, subsequent revisions do not apply. 0 For a non-specific reference, subsequent revisions do apply. 0 A non-specific reference to an ETS shall also be taken to refer to later versions published as an EN with the same number. il GMR-2 01,004 (TS 101 377-01-01): “GEO-Mobile Radio interface specifications: Abbreviations and acronyms“ Note: This document is not yet published.

The carrier spacing is 50 1cHz on the return link. The carrier frequency is designated by the absolute radio frequency channel number (ARFCN) defined as nL for the L-Band channels and n, for the C-Band channels. For the forward links, definition of the carrier frequency also requires specification of the Frequency Offset (FO) parameter which identifies either the baseline frequency plan (FO = O), or the offset frequency plan (FO = i), where the offset plan is obtained by shifting the baseline plan by 75 l and where units for all frequencies are in MHz.

For mobile user terminal equipment with integral antenna only, a reference antenna with O dBi gain shall be assumed. For fixed Mobile Earth Stations, Ground Terminals, and satellite transmitters the requirements are specified in terms of EIRP (Effective Isotropic Radiated Power). The term transmit power refers to the measure of the power when averaged over the useful part of the burst (See Section A.2). The term peak hold refers to a measurement where the maximum is taken over a sufficient time that the power level would not significantly increase if the holding time were longer. 6.1 Transmit Power 6.1 .I 6.1.1.1 Mobile Terminal Mobile Earth Station (MES) The MES output power and corresponding power class shall be as defined in Table 6.1-1. 4 Copyright Telecommunications Industry Association Provided by IHS under license with EIALicensee=IHS Employees/1111111001, User=Wing, Bernie Not for Resale, 03/29/2007 03:06:55 MDTNo reproduction or networking permitted without license from IHS -,-,- TINEIA IS-781.05.005 Power Class 2 Maximum Output Tolerance (dB) Power for Conditions Normal Extreme 39 dBm +I 5, - 0.0 +I 5, - 1.5 3 Power Class 4 shall correspond to a handset. The handset shall have 2.0 dBi antenna gain, and 30 days. The differential burst EIRP tolerance between two different control channels, after initial alignment to the same transmit level, shall be 30 days. Furthermore, the output EIRP actually transmitted by the NCC Terminal at each power control level shall form a monotonic sequence, and the interval between power steps shall be 0.5 dB + 0.2 dB. 6.2 Output RF Spectrum The specifications contained in this section apply to the Mobile Earth Station, the Gateway Terminal, and the NCC Terminal. Due to the burst nature of the signal, the output RF spectrum results from two effects: a) the modulation process; b) the power ramping up and down (switching transients). The two effects are specified separately; the measurement method used to analyze separately those two effects is based on the “ringing effect” during the transients, and is a measurement in the time domain, at each point in frequency. 6.2.1 Spectrum Due to the Modulation and Wide Band Noise The output RF modulation spectrum is specified in Tables 6.2-1 and 6.2-2. A mask representation of this specification is shown in Section A. 1. This mask applies for all RF channels mentioned in Section 4. The specification applies to the entire transmit band and up to 2 MHz on either side. a) Mobile Earth Station The figures in Table 6.2-1, at the listed frequencies from the carrier (in I b) a continuous, static sine wave signal at frequency fi and a level of 49 dBpV (emf) e., -64 dBm); c) any 148-bits subsequent of the 5 1 1-bits pseudo-random sequence, defined in CCITT Recommendation O. 153 fascicle IV.4, modulating a signal at frequency f2 and a level of 49 dBpV (emf) (Le., -64 dBm) such that fo = 2f1 - f2 and If2 - fil = 800 laz.
