Crossbow’s eKo system provides users with a robust environmental monitoring system that allows you to collect data from multiple points in your field quickly, easily and in real-time.

Creating a self organizing mesh network based on Crossbow’s proprietary XMesh technology, every eKo node collects and sends its own sensor data while also relaying data from other eKo nodes in its vicinity. The coverage area of the eKo system is extended by each node’s ability to relay messages through the network back to the base station as it is not necessary for each node to have direct communication with the base as long as it can communicate with its neighbors. The system uses a 2.4GHz band and does not require an RF license or cellular subscription costs.
Proper placement of the nodes in the field is critical for reliable networking and operation.
Radio range is optimal when the units are placed at least 5-12 feet above the ground. A clear line-of-sight between nodes is preferable. Trees, foliage, and canopies that are higher than the antennas will reduce radio range. However, deployments for certain types of crops such as those grown in orchards provide a tall canopy with some clearance to the ground allowing the units to work beneath the canopy as long as they are at least 3 feet above the ground.

The reliability of the network is enhanced by multiple radio connections. If the radio communication from one eKo node to another degrades due to interference, the transmitting eKo node will automatically route to another node within its radio range. This mesh capability provides a robust network giving all nodes multiple radio paths to ensure their data is sent to the base. eKo nodes have a unique algorithm (patent pending) to determine the available radio paths during installation. When turned on the unit will enter a network search mode and signal nearby eKo nodes and/or the eKo base radio to find out how many good radio paths are available and will use the strongest radio path for communication while continually adjusting these paths as conditions change.

New nodes can be added to the network at any time and will automatically join the network by communicating with the eKo Base Radio, which provides a dynamic addressing service for the nodes. The eKo gateway stores and forwards data from the sensor network while the eKoView web service allows users to remotely view sensor data via the internet and monitor the network. The gateway will connect to any standard Ethernet hub or router.
