Telenor Case Study

One of the most significant projects we worked on in 2019 and 2020 was for Telenor, Norway’s largest provider of tele, data and media communication services. With operations across different markets, they are one of the world’s largest mobile telecommunications companies.

Help needed

The idea came from a few members of Telenor’s Consumer IoT team who love dogs and realised there was a gap in the market. There are 600 000 dogs in Norway alone, and almost 88 million across the EU. And while dogs are becoming more and more popular every day, there is not much out there that assuages a dog owner's greatest fear – their beloved pet tearing off after a stray cat or terrified by fireworks and not coming back.

In Norway, this problem is somewhat mitigated by the obligatory microchipping, but even with this technology in place a large number of runaway dogs are never found since the microchip in essence serves more to track the owner of the lost pet, rather than the other way around. Not only that, but the microchip can only be read by specialised technology as they transmit on a special NFC carrier frequency which complicates the localisation process even further.

Enter SolveQ

Working closely with the Telenor team, an innovative solution to this growing problem was developed, in order to help keep everyone’s pets safe. As part of our IoT experience, we created a mobile application that connects to GPS trackers located on dog collars, thus enabling the owners to check where their pets are at all times. Our team at SolveQ created the infrastructure and programmed the trackers to communicate with the application and send real time information about the tracker’s location.

We had to put together a team for this project on very short notice, which required strategic planning of our available resources and restructuring our ongoing projects, but we’re nothing if not flexible. Once we had the team in place, we were able to take on the challenge!

The tracker

Eventually we completed the project, resulting in an innovative pet tracker that was wireless, durable, waterproof and seamlessly integrated with the GPS tracking system. The trackers communicate using LTE-M network which allows for rapid data transfer as well as Bluetooth for certain operations. It’s based on nrf52 SoC, provides access to the developers to a LTE-M/4G combo modem (U-blox SARA R410), GPS (U-blox SARA M8Q), accelerometer and Qi charging.

Backend and infrastructure

In order to be able to expand the platform to other use-cases and devices later we built a structure that enables various trackers (even not of the specific type created for this project) to use the platform and to be tracked. Infrastructure-as-code improvements were put in place to help streamline development and deployment of the platform.

Frontend

The mobile app is built using the ReactNative framework in TypeScript language. It communicates with the backend mainly via WebSockets to ensure that users view the data in real-time. Additionally, it communicates directly with the tracker devices over BLE (Bluetooth Low Energy) protocol if the device is in phone range. The trackers can be shared across users, as implemented through Firebase Dynamic Links.

Besides the main feature of the app (being able to locate your dog), users can register the route of the walk and later browse walk statistics.

Quality delivered

Ultimately we were able to devise and implement a low-power communication protocol so devices did not need to persistently communicate with the backend; also, implementing buffering & batching on the tracker side ensured that the trackers could sustain a long disconnect from mobile network while losing no data. We completed multiple battery-saving optimizations so that trackers would last longer - the battery life was extended from 6 hours of use to 12+ hours. We improved the processes allowing the companion app to check the state of the tracker and implemented direct feedback mechanisms so the application could trigger a mode change in the tracker without requiring backend input.

We are very satisfied with SolveQ and especially with the team working together with us on the Mitt Spor product.

The team works efficiently and delivers as expected, often beyond our expectations. They are always forthcoming to accommodate any new requests and ready to assist if any issue occurs.

Importantly, the team is also proactive and providing us with expert advice [on] how to develop the most robust, stable and flexible solution for the future.

The team members are experienced and professional, and at the same time down to earth and easy to work closely together with.
