"This document defines the requirements for a Wireless General Packet Radio Service (WGPRS) High Speed (HS) Indoor transceiver Requirements are defined for two categories of parameters: ? Those that are required to provide compatibility between the radio 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 the same or adjacent frequency bands. ? Those that define the transmission quality of the system. This document defines RF characteristics for the MS and BSS. The BSS will contain either BTS or micro-BTS. The precise measurement methods are specified in 3GPP TS 51.010-1 and 51.021. Unless otherwise stated@ the requirements defined in this document apply to the full range of environmental conditions specified for the equipment. MSs may operate on more than one of the frequency bands specified in section 2. These MSs are referred to as ""Multi band MSs"" in this document. Multi band MSs shall meet all requirements for each of the bands supported."
