panOULU WSN is a network of access points of Wireless Sensor Network (WSN) that is being built.

panOULU WSN network’s access points are based on IEEE 802.15.4 technology and with a 6LoWPAN protocol stack, they offer a multi-hop, half-duplex data transfer for sensors with a low energy consumption. panOULU WSN access points route the data collected by the sensors forward to a GSN (Global Sensor Network) server. The GSN server saves the data and refines it forward for the client.

The access points installed in June 2009 use a 2.4 GHz frequency band. In autumn 2009, the access points are updated to use a frequency band of 868 MHz, which is more suitable for the transfer of the measurement data of low-power sensors.
A prototype service provided with the panOULU WSN network is UBI-AMI.
