The Sperry
Marine NAVICOM F 77 marine satellite communications terminal offers high-speed
and cost-effective voice and data communication based on either the MPDS (Mobile
Packet Data Service) protocol with constant online access or a 64 kbps ISDN
connection.
With MPDS you are only charged for the
amount of data sent, not for the time the channel remains open, making it the
most economic and convenient solution for e-mail, small- and medium-size
transfer, LANs, VPNs and Internet.
ISDN services provide a high-capacity
channel with a constant data stream and are usually preferable for uploading or
downloading large files.
