The ‘Fixed Docking Unit’ (FDU) allows satellite usage in an indoor environment such as home or office. It complements the Thuraya phone by extending its operations and functionalities inside buildings where the satellite signal is not sufficient. Simply dock the Thuraya phone in ‘FDU’ and you’re ready to use it indoors. All the standard satellite-based services such as voice, fax/data and the supplementary services will be available when the phone is docked.
