Link
To establish:To establish:- a radio link between VeA (Ventspils University a radio link between VeA (Ventspils University
College) and Ventspils Nafta in LatviaCollege) and Ventspils Nafta in Latvia
- a high speed fiber link between Ventspils a high speed fiber link between Ventspils Nafta and Fårösund (Gotland, Sweden) Nafta and Fårösund (Gotland, Sweden)
- a connection between Fårösund and Kistaa connection between Fårösund and Kista

26 GHz Radio Link+ High data rate (155 Mbit/s)+ Stable connection
- Expensive- License required
Radio LinkVeA – Ventspils Nafta
Distance 7 Km
Link Overview
Our choice 5,4 GHz Radio Link + License free frequency+ Cheap equipment
- Moderate data rate (up to 36 Mbit/s)- Limited range- Less stable than the 26 GHz solution
