Skylink
1998–2003
As wireless links in the licence-free 2.4 GHz band became more affordable, and before Wi-Fi had taken off, we gradually built and operated wireless metropolitan networks based on BreezeNET technology in Roudnice nad Labem, Litoměřice, Lovosice, and above all in Prague. The wireless network traded under the name Skylink and used the domain skylink.cz, which today belongs to an internet television service.
The large number of wireless links, routers and switches demanded monitoring for both oversight and capacity planning. Together with colleagues, I designed and progressively implemented a monitoring system built on the Scotty SNMP library and a PostgreSQL database. The system was written in Tcl and PL/pgSQL, with a Java frontend.
