Application

Assets Localization Tracker

• The WOLT can be used for efficient combined D7A/LORAWAN tracking due to the combination of long / mid / short range connectivity. It is also useful for identification due to its NFC connectivity.
• The RSSI-based location provides accuracy up to 3 m.

Ready to deploy

• The WOLT-D7A is suited for proof of concept, pilot and volume applications. By default, it is provisioned with LoRaWAN credentials for TTN (www.thethingsnetwork.org). For DASH7 communication, WizziLab provides infrastructure for easy D7A network deployment. The WOLTD7A seamlessly connects to the WizziLab’s DASH7 Industrial IoT platform.
