Project Overview


TWISTER key elements

• Three-year programme started on 1 February 2004

• EADS Astrium coordinates a consortium of 12 partners

• Overall budget is 8,5 M�, of which 5 M� funded by the EC under the 6th Framework Programme

• TWISTER deploys and operates validation sites in rural areas throughout Europe combining bidirectional satellite broadband services with wireless local networks

• Target application areas: in the domains of agriculture, education, community services, health care and e-business


Project Objectives

Objective 1 : Provide content & applications adapted to rural areas

Objective 2 : Investigate and validate beds the integration of DVB- RCS satellite communications standards with

wireless technologies

Objective 3 : Develop and validate a set of service metrics to quantify network performance and

usage

Objective 4 : Validate performance of interoperable DVB-RCS terminals at end-to-end application level

in a real operational environment

Objective 5 : Improve the use of satellite capacity

Objective 6: Define and disseminate technical guidelines

VALIDATION SITE INAUGURATIONVALIDATION SITE INAUGURATION

Validation site design and

deployment process


Satellite component: types of connectivity

� Two-way broadband satellite internet access services

– Two solutions: ARC 2000+ by Aramiska & D-Star by Eutelsat

– Star network topology

– DVB-RCS based

– ISP services

– Ku band (AB2 and e-Bird)

� Two-way broadband satellite mesh connectivity

– Skyplex by Eutelsat

– Direct terminal to terminal communications

– Ka band (Hotbird 6)


Satellite component: benefits of DVB-RCS

� Powerful modulation and coding techniques

� Bandwidth on demand (BoD) functionality– Efficient and flexible sharing of satellite capacity between users

– A scalable solution for satellite service providers with respect to renting satellite capacity

– Resource sharing is facilitated by the DVB-RCS framing structure and terminal access to forward link signalling

� Low price user terminal compared with traditional VSAT– Less than 5000 euros instead of 10 000 to 20 000 euros

� Mature and operational solution– Since start of the first validation sites operations in June very

satisfactory operations of the satellite broadband services

– Easy and rapid to deploy


Network management component: QoS

� The following QoS features are implemented in theTWISTER validation sites:

– Traffic shaping according to- Users- Groups of users- Applications

– Bandwidth allocation- Guaranteed /

maximum bandwidth- Scheduling- Priorities

� The QoS Management Equipments allow to retrieve data statistics for the performance and usage evaluation ofTWISTER validation sites


Network management component: Security

� The following security features can be implemented in the TWISTER validation sites:

– Protection against security attacks from the Internet- NAT, port forwarding, firewalls, Web filtering, VPNs

– Wireless network security- WEP: activated by default- MAC address filtering: activated by default- Alvarion scrambling protocol:

– Virtual Private Networks: Lajski

– User Authentication, Authorisation and Accounting- Picopoint solution: Ardisa, La Almolda, Moyuela,

Pozuelo, Allier, Dordogne, University of Warsaw,Vianne, Paracuellos, Alpartir

- Dedicated RADIUS server: University of Malta, Lajski


Regulatory issues – salient points

� Significant efforts to find a frequency band, and to obtainthe appropriate licence, allowing to meet the specific user requirements for Greek validation sites:

– high bandwidth for medical applications

– large distances (> 4 km) between sites

– hostile environment for direct sequence propagation

� 5.4 GHz band reserved for mobile services

� 5.8 GHz band earmarked for FWA in Europe but not yetopened in Greece

– Greek radio regulations body EETT rejected our request for an experimental licence in this frequency band

� TWISTER promotes the opening of 5725-5875 MHz band atEuropean level for Fixed Wireless Access


SUMMARY



� TWISTER Network Operations


• Conclusions


Network Operations


TWISTER Network Operations Structure

� Hotline & end-user support– A unique phone number to call in case of network problems

– Definition of roles and procedures (local site administrator, site coordinator)

� Network monitoring and management– Creation of a Network Operations Centre

– Remote supervision and configuration of validation sites

� Maintenance procedures– Definition of roles and procedures in case of equipment replacement

� Contractual aspects– Equipment & services are provided by TWISTER to the validation site

users

– To establish the rights and responsibilities of each partner

– Creation of an « End-user agreement » and « Validation site agreement »
