1 The DVB-RCS competitive opportunity for new services Axel Jahn TriaGnoSys GmbH March TriaGnoSys GmbH - 1

2 Background DVB-S/S2 / RCS are mature standards DVB-S/RCS networks are being deployed worldwide DVB-S2/RCS has competitive advantages compared to DoCSIS and IPoS Mobile applications are being discussed for DVB-RCS Ships, aircraft, trains EC MOWGLY project ESA activities Mobile TV reception using DVB-S/S2 is rolling-out GSM / UMTS backhauling via satellite is starting for mobile aeronautical services (via Inmarsat) for fixed applications via Ku-band March TriaGnoSys GmbH - 2

3 DVB-S2 Adaptive coding and modulation Large fading robustness Reduces cost by 2-3x Increases availability Special communications profile DVB-RCS updated with S2 Data Rate per BW unit 4 3,5 3 2,5 2 1,5 QPSK DVB-S2 8PSK 16APSK 8PSK 32APSK 0,35 16QAM DVB-DSNG 0,20 0,25 0,35 1 DVB-S 0, Signal Strength March TriaGnoSys GmbH - 3

4 IPoS IPoS stands for IP over Satellite Recently TIA and ETSI approved specification for satellite broadband systems TIA reference: TIA-1008 There 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 concept As of now IPoS has one vendor IPoS used to be called DirecWay and DirecPC. IPoS has subscribers. 95% use satellite return. March TriaGnoSys GmbH - 4

5 DOCSIS-S DOCSIS: Data over Cable Service Interface Specification DOCSIS 1.0: North American standard, Spec 1997 DOCSIS 1.1: Adds VoIP, QoS, enhanced IP Multicast, Spec 1999 Euro-DOCSIS: European standard DOCSIS 2.0: Adds higher order modulations, Spec 2001 DOCSIS 1.1 (According to ITU-T J.83-B): - RS-Coding, Interleaving, Trellis coded Modulation - 64 QAM or 256 QAM Mbps (Euro-DOCSIS: Mbps) Surfbeam DOCSIS over Satellite System: DOCSIS-S over satellite: not standardised - Dynamic multi-rate forward link with auto adjustment due to fades - Rate 2/3, (3/4), 5/6, (8/9) Turbo Code with 8PSK - Rate 1/2, (5/8), (3/4), (7/8) Turbo Code with QPSK - Reed-Solomon outer code - Optional all DVB-S compliant FEC - Nominal Data Rates 5-50 (108) Mbps - Theoretical max efficiency ~2.25 bps/hz March TriaGnoSys GmbH - 5 (ANSI/SCTE 23-1 DOCSIS 1.1 Part1

6 DVB-S2/RCS IPoS DOCSIS-S Comparison DOCSIS-S (Surfbeam) DVB-RCS IPOS Frame formats Upstream Burst: Header & Ethernet frame Downstream: MPEG-TS stream Upstream: Burst of MPEG or ATM cells Downstream: MPEG-TS stream DVB-S or DVB-S2 Upstream: variable bursts,x7,8,9 Downstream: MPEG2 DVB-S or DVB-S2 Typical max data rates Upstream: 1203/ (2406) kbps Downstream: 50 (108) Mbps Upstream: 2048 kbps Downstream DVB-S: 45/68 Mbps, DVB-S2: 100+Mbps Upstream: 2048 kbps Downstream DVB-S: 45/68 Mbps, DVB-S2: 100+Mbps Modulation & Coding Upstream: QPSK: Turbo 1/2, (3/4), optional RS outer code Upstream (DVB-RCS): QPSK, Turbo or CC&RS Upstream: O-QPSK, Turbo C. or CC Code 1/2 Adaptive Coding and Modulation Downstream: 8PSK: Turbo 2/3, (3/4), 5/6, (8/9) QPSK: Turbo 1/2, (5/8), (3/4), (7/8). RS outer code Yes, some options Downstream (DVB-S2): QPSK, 8PSK, 16 APSK, 32 APSK, many different code rates Downstream (DVB-S): QPSK, Conv.&RS Code, var.code rates Yes. RCS: Adaptive coding. S2: ACM Downstream (DVB-S2): QPSK, 8PSK, 16 APSK, 32 APSK, many different code rates Downstream (DVB-S): QPSK, Conv.&RS Code, var.code rates Yes IPoS: Adaptive coding and symbol rate.

7 DVB-S2/RCS IPoS DOCSIS-S Comparison DVB-RCS IPOS DOCSIS-S (Surfbeam) QoS Support Yes (based on TCP, IP, or Ethernet header) Yes Reservation flow specs Yes Physical layer efficiency Forward link: o Return link: o Forward link: DVB-S: o DVB-S2: ++ Return link: o Forward link: DVB-S: o DVB-S2: ++ Return link: o Return link MAC eff.: Advantages Works like a huge Ethernet (big address space), only one PID value necessary Open standard, multiple vendor support, compliance organization, SatLabs. Open standard, large number of terminals in operation. Low cost. Disadvantages High uplink overhead for short IP datagams -> ACK, VoIP. No standard, single vendor, no compliance organization Perhaps more time to change the system is required than for proprietary systems. Few vendors, no compliance organization March TriaGnoSys GmbH - 7

28 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.
