Use of various wireless communications network standards or GPS for positioning is well known from countless previously published research articles. Joining of positioning principles with data artefacts prebuffering can provide a many advantages in using of mobile devices as a clients of remote server on-line systems. On of the key aspects can be seen in rapid increasing of data throughput of download connection (downlink). The user requested data artefact can be preloaded to mobile database cache (SQL Server CE), from where it is accessible through a user software application. Accessing time of artefacts from mobile cache (physically located on SD Card) is fraction in compare to a classical on-line accessing the data artefact from server through a web services.
