EXPLORER Push-To-Talk or PTT:

…extends classical Push–To-Talk capabilities to hybrid data networks such as terrestrial 2G/3G/GPRS networks supplemented by the Inmarsat BGAN where no terrestrial network coverage is present.

…offers seamless least cost routing (voice/data).

…is based on VoIP optimized for difficult link conditions.

…offers true BLOS communication and global coverage.
