TWISTER overview- Current status, main outcomes, lessons learned -

Rhodes, 05/07/2006



TWISTER key elements

Three-year EC programme (FP6, Call 1) started 1st of February 2004

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

The validation site period corresponds to 18 months starting from the satellite terminal equipments installation

Target application areas: in the domains of

– Agriculture

– Education

– Community services

– Health care

– e-business



TWISTER ConsortiumRepresentative of the whole supply chain

Ouranos-Networks



Summary of major TWISTER achievements

More than 100 validation sites deployed through the enlarged

Europe

More than 50 validation sites are hybrid networks coupling

satellite access with wireless local terrestrial networks

More than 10 countries concerned (France, Spain, Italy,

Denmark, Ireland, Greece, Malta, Poland, Romania, Croatia,

Bosnia, Hungary)

Already 10 validation sites have ended their validation period of

18 months



Example of TWISTER validation siteDordogne (France)



Typical validation site deployment process- Strongly recommended to apply it to Rural Wings -

Validation site user and service requirements report

Site survey

Validation site network design

Prerequisites for installation

On-site installation

Validation site acceptance test

Usage and evaluation period

At this stage of Rural Wings, only these aspects are being addressed

Budget constraints per site



Lessons learned from TWISTER Encountered Critical Points

Site Survey

Geographical topology matters

Network Architecture Design

Technical constraints and equipment costs

Site Installation

Who will be responsible of site installation and when?

How to do acceptance test review?

Maintenance

Who will intervene?

Who will reboot or replace the equipment?

Supervision

Who will supervise the system and send alert?

Monitoring

How to estimate the usage of the pilot site?



Network Operations Structure

Hotline & end-user support

– A phone number to call in case of network problems

– Need for a local site administration

– Definition of roles and procedures

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 »



TWISTER Anomaly Distribution per Kernel Validation Site from January to December 2005

Way forward for Rural Wings wireless networks- Critical points to address in the coming weeks -

Detailed user requirement forms necessary

– Form templates to be provided by EADS Astrium

Mid of July 06 (Ariane Muller)

– To be fulfilled by National Coordinators

September 06

Guidance for installation requirements

– To be provided by EADS Astrium

End of July 06 (Ariane Muller)

– To be used by National Coordinators for installation activities

Support needed from other partnersWireless network deployment issues: environmental conditions

Conditions of wireless transmission Line of sight and topography Meteorology Opened zone of Fresnel Relative elevation of sites Vegetation

Physical constraints Possibilities of mast installations Points accessibility (roof, tower, etc…) Cable length between antenna and wireless unit



Support needed from other partnersWireless network deployment issues: environmental conditions

Electrical conditions– Verify quality of electrical network – Use of UPS equipment is recommended

Temperature & Humidity operating– Outdoor equipment: use specific equipment with adequate temperature

and humidity operating range– Indoor equipment: select sites with air conditioning or warming for

central point (no direct sun, no attic, …) Visual aspects

– Respect design of building when it is possible (hidden antennas, …)

– Pay attention to ancient monuments : castle, tower, ancient house, church,…



Support needed from other partnersChecklist for initial site layout

– Indicate building positions on map

– Identify high points

– Is a special authorization necessary to install antenna ? (historic building,…)

– Identify type of user (single user, multi-user, etc.)

– Identify connection priorities
