History of the initiativeHistory of the initiative
Agora : Affordable and Guaranteed Offer for Rural Access
European political willingness to close the « digital divide »
2004 : Design studies done by CNES and rapidly confirmedand detailed by strong industrial involvement (Alcatel, EADSspace, Thomson, …)
Market studies and Benchmarking of the solution tounderstand the conditions of private investment.
Framework suitable for private investment in a sustainableapproach
