ETSI TS 137 144 establishes over the air antenna minimum requirements for user equipment (UE) and mobile
station (MS).
Handheld UE requirements are defined for roaming bands for the speech position (beside the head and beside the head
and hand) and hand phantom browsing mode position. Laptop mounted equipment requirements are defined for
roaming bands for the data transfer position (laptop ground plane phantom). Laptop embedded equipment requirements
are defined for roaming bands for the data transfer position (free space).
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
cannot 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.
