We have effectively eliminated the need for expensive SIM cards and needing to deal with lacking mobile network coverage. Our collars are programmed to send it's data through our own network of base stations, which we plan the deployment of together with our customers.
The collar weight is only 250 grams but the battery still sustains the unit for over 2 years on a single charge - even in an arctic climate. This is because the data is transmitted through our own energy-effective network. The battery can be recharged without opening up the unit using our wireless battery charger.
The collar is completely encapsulated and waterproof (IP67) to ensure avoidance of moist, dust or other issues. It's design also minimizes the collection of ice on the unit. The unit's antennas are all integrated in the device for best protection.
The Collar collects it's GPS position, mortality status and other data 7 times a day, every day, year-round. If needed the Collar itself can store collected data for up to 4.5 years. Stored tracking information is transmitted every hour when within the reach of a Tannak base station and it can also be extracted from the Collar using a smartphone with NFC.
