Wireless Sensor Networks are networks composed of small electronic devices that collect and transmit data to each other to locate their position in real time and to measure physical data in certain areas and environments. In most cases a WSN can be easily moved no cabling costs are required. Wireless sensor networks typically operate on frequencies of 868 Mhz and/or 2.4 GHz and enable real-time (indoor-outdoor) location of tagged individuals, as well as, if required, also monitoring of their activity (kinematics) with 3D-type (multi-floor) surveys. The most widely used standard for this technology is Zigbee.
