context: The manufacturer shall declare whether the BS under test is intended to operate in geographic areas where the additional operating band unwanted emission limits defined in clause 6.6.2.4 of TS 37.104 [2] apply. If this is the case, conformance with the applicable emission limits shall be demonstrated. NOTE: For the emission limits established by FCC Title 47 [8], there is no test method or requirement defined in the present specification. For a BS declared to support Band 20 and to operate in geographic areas within the CEPT in which frequencies are allocated to broadcasting (DTT) service, the manufacturer shall additionally declare the following quantities associated with the applicable test conditions of Table 6.6.2.5.4.4-1 and information in annex G of TS 36.104 [5] : PEM,N Declared emission level for channel N P10MHz Maximum output Power in 10 MHz Conformance with the declared emission level PEM,N shall be demonstrated. For a BS declared to support Band 32, 75 or 76 and to operate
description: Delay Spread (DS) is a parameter used to quantify the dispersion of signal arrival times in a wireless communication channel. It is an important factor in determining the performance of wireless systems, particularly in terms of intersymbol interference and bit error rate.
explanation: The context explicitly states that Delay Spread (DS) is a parameter used to measure signal dispersion in a wireless communication channel. This definition aligns with the typical understanding of parameters within telecommunications.
