Overall Goal Demonstrate an interactive workspace between Ventspils University College (VeA) and the Royal Institute of Technology (KTH). iSpace Implementing an iRoom at VeA Link Establishing a high speed direct link between KTH and VeA

iSpace

iSpace is a high-technology room that facilitates group meetings and enables interactive distance learning. iSpace is a high-technology room that facilitates group meetings and enables interactive distance learning. Design: Design: –Remote lectures: VeA receives a lecture VeA receives a lecture VeA hosts a lecture VeA hosts a lecture –Remote group meetings: With the use of iROS (interactive room operating system), far apart scientists will find themselves as colleagues working in the same room. With the use of iROS (interactive room operating system), far apart scientists will find themselves as colleagues working in the same room. iSpace

Link

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

Ventspils Ventspils Nafta Fårösund Utö Stockholm 26 GHz Radio Link + High data rate (155 Mbit/s) + Stable connection - Expensive - License required Radio Link VeA – 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 Radio Link Solution VeA – Ventspils Nafta 7 Km

Tsunami MP11/a 24 Mbit/s 45 cm Parabolic antenna 20 dBm => 1 W output

Ventspils Ventspils Nafta Fårösund Utö Stockholm SDH Fiber Link Media Converter + Cheap equipment - Relatively low bit rate, 100 Mbit/s - Not upgradeable Fiber Link Ventspils Nafta – Fårösund Distance 175 Km Reduction 33 dB

CWDM Fiber Link + High data rate + Relatively cheap equipment - Cannot handle long distances without amplifier - Requires more bandwidth because of wide spectra Fiber Link Ventspils Nafta – Fårösund

DWDM Fiber Link + High data rate, 2,5 Gbit/s + Upgradeable to at least 10 Gbit/s - Expensive Our choice Fiber Link Solution Ventspils Nafta – Fårösund

Extraordinary Circumstances Dependencies on external decisions Dependencies on external decisions Internal dependencies Internal dependencies Every step towards reaching the goal was considered a success Every step towards reaching the goal was considered a success

As of Today Success! Success! –Overall goal reached –iSpace goal reached –The link will with a very high probability be operational before summer 2004

For the Future Do the final installations of the fiber link Do the final installations of the fiber link Establish a long term relationship between VeA and KTH Establish a long term relationship between VeA and KTH Expand the network further east Expand the network further east
