Universal Mobile Telecommunications System (UMTS); User Equipment (UE) and Mobile Station (MS) over the air performance requirements (V11.2.0; 3GPP TS 25.144 version 11.2.0 Release 11)
The present document establishes Over the Air antenna minimum requirements for User Equipment (UE) and Mobile Station (MS). Requirements are defined for roaming bands for the speech position (beside the head) and for the data transfer position (free space). Requirements for free space are applicable to devices used in the data transfer position and consist of laptop mounted equipment (LME) plug-in UEs and laptop embedded equipment (LEE) UEs. All bands are potential roaming bands@ and the requirements for roaming bands shall therefore be fulfilled for all bands supported by a UE/MS. Requirements for operating bands are dependent on how the network has been built and are thus operator specific and can not be specified here. Recommended performance values for operating bands (Annex B) are however included in this specification for information. It should be recognised that the ability to meet the recommended performance values depends on the number of frequency bands supported by the UE/MS.
