ZIGPOS has focused on high energy efficiency in Sensor- /Actuator Networks that helps to optimize solutions for own applications.
Wireless Sensor-/ Actuator Networks (WSAN) consists of sensor modules, communicating wireless to exchange sensor data from the environment (temperature, humidity, gas etc.) and control/regulate the environment via actuators (thermostat, climate, power plug etc.). The Main difference in various network concepts is the composition. Whether they are centralized or realized in a decentralized ad-hoc approach. Both options have advantages and disadvantages vary based on the application scenario.
ZIGPOS main experience focus on sensor network based on IEEE 802.15.4. This standard define the area of wireless personal area networks (WPAN) and is mainly used for energy efficient transmission with low data rate (mainly sensor data). Based on this standard various protocol stacks available competing to each other e.g. ZigBee, 6LoWPAN, Wireless HART and many proprietary solutions. Due to our long term operating experience in wireless sensor networks ZIGPOS GmbH offers a choice of used network protocols for optimal realization of own applications based on user preferences.
Next to standard solutions ZIGPOS developed an own network protocol, that is next to the very high energy efficiency (battery life times up to several years) capable to integrate the eeRTLS technology. With this technology sensor data cannot only be transmitted but rather located inside the environment which leads to totally new application scenarios.
