Spanish to English Tech/Engineering Telecom(munications)

I know what this phrase means - access to an Intranet via a mobile phone - but which is the most accurate and concise English. It is used in a heading many times so can't be too descriptive:
MOBILE INTRANET ACCESS
INTRANET MOBILE ACCESS

The explanation is "El servicio de Acceso Móvil a Intranet ofrece la posibilidad de que un usuario móvil o remoto pueda acceder a la Intranet"

Thanks in advance!
