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

– 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 »

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
