Brief History of Internet in CZ
1990 – connection of the Czech Republic to EARN/BITNET 1991 – first experiments with TCP/IP protocol, grant “Establishment of the University IP Network” 1992 – Ministry of Education, Youth and Sports - 20 mil. of CZK, start operation of CESNET 1994 - INET Conference in Prague 1996 - leased line open to competition2000 – 2,5 Gbps IP service between Prague - Brno2001 – 2,5 Gbps country-wide infrastructure CESNET2 operational2002 - 10 years of Internet services in Czech Republic

1996
- liberalization of the leased line provisioning
- very positive role of the European Comission
- strong lobbying required
Access to dark fiber
1996
- call for tender for TEN-34 CZ (34 Mbps national infrastructure)
Two offers
1) Czech Telecom - optical infrastructure available - price unrealistic - monopoly behavior
2) Czech Radiokomunikace - 34 Mbps microwave links - not proven technical solution - realistic price - co-operative approach
1996 – 1998
- several alternative providers (power, oil, gass distribution companies, railways, etc.) built fiber optic infrastructure
- everyone start with infrastructure between major cities
- everyone want to sell services (bandwidth) only
1999
Telecom market situation in CZ - offer much higher than demand
Convinced one company (MERO) lease dark fiber between Praha – Brno for pilot project.
Prague-Brno circuit capacity 2,5 Gbps
2000
January – 2,5 Gbps pilot IP service operational
Partner (MERO) received:
- payment (covering cost) - results of the pilot project (joined technical team) - extensive publicity in all types of media
2000
Summer - call for tender for 2,5 Gbps country-wide connectivity
Fall - contracts for seven 2,5 Gbps lines with six suppliers signed (both dark fiber lease and „lambda“ services) - both CESNET and service providers provide and operate regenerators - fibre optics lenght is cca 50 – 80 % longer than road distance
Last (First Mile Issue)
- concept of „meeting“ point
- joined investment of fiber provider, CESNET and local organization to fiber between „meeting“ point and CESNET PoP location

Conclusions
- competition is esential requirement (lobby for competition) - telecoms (bandwidth providers) must see NREN as partner – not a competitor (define and adhere to AUP) - PR activities on all levels are very importnant
