In Addition ..
and even better than Inmarsat
Multiple voice channels
DVB-RCS standard provides scalability
No practical limitation on channel speeds
A lot of available bandwidth, works on all bands, Ku/Ka/C-band satellites
Much lower bandwidth costs, fixed cost/month.
QoS over IP

Very Powerful VoIP Performance
Example from deliveries to Telemar in Brazil in co-operation with Siemens:
Without header compression:
12- 13 kbps per voice channel each direction
With header compression:
10 - 11 kbps
Voice is prioritised in order to reduce delay and for high quality

Challenges Using DVB-RCS For Mobile Solutions
Compared with Inmarsat:
Today's coverage mainly in Americas and Europe
Rain fading in e.g. South East Asia and parts of South America
Service availability down to 99,5 %
Lacks roaming between operators and also within same operator
Higher equipment cost
Larger size of equipment
All these challenges will be solved or reduced

Roaming And Hand-Over For Maritime
Nera will offer terminals which can do:
automatic switch-over between beams and operators of
DVB-RCS compatible Gateways
automatic switch-over to e.g. Inmarsat Fnn in areas
lacking DVB-RCS coverage

Rain Fading Challenges
DVB-RCS offers a tool box for maintaining the return link with heavy rain fading
Automatic changing code rate and symbol rate is implemented in the Nera Gateway
Best spectral efficiency or speed under all link conditions
DVB-S2 will offer the same tool box in the forward direction
Automatic changing code rate and modulation technique

Key Trends In Maritime Communication
Maritime applications demand higher and higher bandwidth
More and more routes at sea will be covered with broadband services
Demands for fixed monthly cost is expected similar to ADSL provision
A combination of different satcom systems will be installed in order to
serve different needs and leased cost routing
Customers expect easy upgrade and reuse of existing infrastructure
onboard as well as on shore
