Outdoor Nodes
The new generation of outdoor nodes is a reality!! The upgraded WiFi nodes have been developed by the NITLab team and support MIMO operation. The new version of outdoor nodes are equipped with 802.11a/b/g and 802.11a/b/g/n wireless interfaces. They also feature 2-core Intel cpus, new generation solid state drives and usb web cameras. Last but not least, each node is equipped with light, temperature and humidity sensors.

To control and monitor Icarus node's operation we use NITlab's Chassis Manager Card (CM card). A tiny web server is running on the CM card and serves http requests, such as power on/off and reset commands. Further more, CM card can support real time sensor measurements, since it can be connected with temperature & humidity sensors as well as with light sensors.
Two leds are used to indicate the operation status of the outdoor nodes. More specifically a two state led, located on the side, indicates the power status of the node. If the led is red the node is turned off and if the led is blue the node is turned on. The same led flashes in red mode each time the cm card serves a request.
The second led is on the cm card and indicates the connection of the node to the power supply.
