Background

DVB-S/S2 / RCS are mature standardsDVB-S/RCS networks are being deployed worldwideDVB-S2/RCS has competitive advantages compared to DoCSISand IPoS

Mobile applications are being discussed for DVB-RCSShips, aircraft, trainsEC MOWGLY projectESA activities

Mobile TV reception using DVB-S/S2 is rolling-out

GSM / UMTS backhauling via satellite is startingfor mobile aeronautical services (via Inmarsat)for fixed applications via Ku-band

IPoS

IPoS stands for “IP over Satellite”Recently TIA and ETSI approved specification for satellite broadband systems

TIA reference: TIA-1008There is a cross acceptance liaison between ETSI and TIA This does not imply it is a “standard”.

Spec covers basic design structure of terminals and the formatting of signals between the hub station and the end user terminal Aims to incorporate the ETSI standard (SI-SAP)Satellite Independent Service Access Point conceptAs of now IPoS has one vendorIPoS used to be called DirecWay and DirecPC. IPoS has 300.000 subscribers. 95% use satellite return.

DOCSIS-S (Surfbeam)IPOSDVB-RCS

Few vendors, no compliance organization

Perhaps more time to change the system is required than for proprietary systems.

High uplink overhead for short IP datagams -> ACK, VoIP. No standard, single vendor, no compliance organization

Disadvantages

Open standard, large number of terminals in operation. Low cost.

Open standard, multiple vendor support, compliance organization, SatLabs.

Works like a huge Ethernet (big address space), only one PID value necessary

MOWGLY

(MObile Wideband GLobal Link sYstem) MOWGLY aims at studying the implementation of DVB-S2/DVB-RCS standards for broadband access to users of collective mobile vehicles (aircraft, trains and vessels). MOWGLY will investigate innovative solutions for satellite terminals in mobile environments, such as advanced medium access control for a crowd of passengers using the collective terminals with QoS control and networking technologies. MOWGLY will implement a demonstrator and validate both critical services and functions of satellite access systems.
