14. - EADS Astrium Proprietary & Confidential - 13 - EADS Astrium Proprietary & Confidential - 05/07/2006, Rhodes Support needed from other partners Wireless 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,…

15. - EADS Astrium Proprietary & Confidential - 14 - EADS Astrium Proprietary & Confidential - 05/07/2006, Rhodes Support needed from other partners Checklist 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
