On June 29, 2011 Wireless Leiden has rebuilt the old, but no longer functioning, node "Kaag2" on the roof of the building of
Royal Van Lent on the Kaageiland ("Island of Kaag") conform the IRIS-concept of Wireless Leiden.
Rebuilding has been sponsored by the
Stichting Promotie Kaag (SPK) and the node therefore is now called
node SPKaag2.
There are interlinks to Kaag1 (to be rebuilt soon), Unigor and Watertoren (Water Tower) in Aalsmeer.
