ETSI ETSI TS 145 056 V14.0.0 (2017-04)83GPP TS 45.056 version 14.0.0 Release 144.2 Reference configuration The reference configuration for the CTS-FP radio subsystem is described in GSM 05.01. 4.3 Transmitte
40、r characteristics Throughout this clause, unless otherwise stated, requirements are given in terms of power levels at the antenna connector of the equipment. If an active device is added to the CTS-FP antenna connector, the requirements of this clause shall also be met at the output of this active d
41、evice. For equipment with integral antenna only, a reference antenna with 0 dBi gain shall be assumed. The term output power refers to the measure of the power when averaged over the useful part of the burst (see annex B). The term peak hold refers to a measurement where the maximum is taken over a
42、sufficient time that the level would not significantly increase if the holding time were longer. 4.3.1 Output power The CTS-FP maximum output power and lowest nominal output power shall be, as defined in the following table. GSM 900 DCS 1 800 Tolerance (dB) for conditions normal extreme Maximum Nomi
43、nal output power 11 dBm 12 dBm +0/-2 +0,5/-2,5 Lowest Nominal output power -9 dBm -8 dBm 4 5 The different power control levels needed to support downlink adaptive RF power control (seeGSM 05.08) shall have the nominal output power as defined in the table below, starting from the power control level
44、 for the lowest nominal output power up to the power control level for the maximum nominal output power as defined in the table above.

46、12 -4 4 513 -6 4 5 14 -8 4 5NOTE: The above definition of the power control levels for GSM 900 and DCS 1800 allows to have an equivalent indoor coverage when the same power control level is applied in GSM 900 and DCS 1800. Furthermore, the difference in output power actually transmitted by the CTS-F
47、P between two power control levels where the difference in nominal output power indicates an increase of 2 dB (taking into account the restrictions due to nominal maximum and lowest output powers), shall be +2 1,5 dB. Similarly, if the difference in output power actually transmitted by the CTS-FP be
48、tween two power control levels where the difference in nominal output power indicates an decrease of 2 dB (taking into account the restrictions due to nominal maximum and lowest output powers), shall be -2 1,5 dB. 4.3.2 Output RF spectrum The specifications contained in this clause apply to CTS-FP,
49、in frequency hopping as well as in non frequency hopping mode. Due to the bursty nature of the signal, the output RF spectrum results from two effects: - the modulation process; - the power ramping up and down (switching transients). The two effects are specified separately; the measurement method used to analyse separately those two effects is specified in GSM 11.56. It is based on the “ringing effect“ during the transients, and is a measurement in the time domain, at each point in frequency. The l
