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)

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
