client background

The company creates consumer IoT products and specializes in connected wearables.

business challenge

The client required a solution that would evolve the capabilities of its next generation of smartwatches. The client needed its smartwatches to provide location coordinates to the smartwatches’ owners in the event of an emergency. Due to market expansion for the smartwatches (initially they were sold exclusively in South Korea), the client required that the smartwatches connection standards be updated to be compatible with any country in the world – and that any potential errors with differing grid frequencies be eliminated.

portfolio solution

Communication standard LoRa works on different grid frequencies in different regions. First-generation smartwatches worked well in South Korea only and when the manufacturer extended the geography of products, resolving any connection issue became crucial.

Our team upgraded LoRa to eliminate this problem, allowing the smartwatches to work seamlessly in any country. The necessary changes conflicted with other performance processes so our engineers updated the operation logic of LED, timing, encryption etc.

Also, we implemented changes to the GPS work processing that increased its accuracy and decreased its power consumption. The changes elongated the battery life.

portfolio solution
  • Enabled product’s market expansion
  • Power consumption was decreased by 60%
  • SKU configuration process was optimized
  • Communications between device and server were improved (LoRa update)
  • GPS accuracy was increased for better location tracking
