Loop One uses reliable and secure communication
Measurement data is securely stored and sent by the Loop One device over cellular LTE network to our cloud service that provides comprehensive indoor air quality status to users on mobile, tablet or computer display.
Loop One is efficient and low power
The radio features of Loop One are built on top of the Nordic Semiconductor’s nRF9160 low power SiP with integrated LTE-M/NB-IoT modem and GPS. Incorporating an Arm Cortex-M33 application processor solely for applications, a full LTE modem, RF Front End (RFFE) and power management system – nRF9160 is one of the most compact, complete and energy-efficient cellular IoT solution on the market.

Security is best-in-class with Arm TrustZone technology for isolation and protection of normal and secure zones for firmware and elements of hardware including memory and peripherals. Arm TrustZone enables solid and secure ioT applications that feature secure boot, trusted firmware updates and root of trust implementations without performance compromise.
Arm CryptoCell enhances device security still further by offering cryptographic and security resources to help to protect IoT applications from various attack threats. In addition, common security measures are naturally used by Loop One on data transport level (TCP/TLS). Network communication is secure and based on strong security mechanisms of the mobile LTE network. The measurement data is stored securely into a cloud service for smart analysis and user-friendly presentation.
Loop One provides excellent coverage and cost-efficiency
Loop One uses the licensed radio technology of existing LTE cellular networks that guarantees a cost effective, reliable, and low power solution.The nRF9160 used inside Loop One supports both SIM and eSIM for connection and authentication with mobile network operators. LTE bands B1, B2, B3, B4, B5, B8, B12, B13, B14, B17, B18, B19, B20, B25, B26, B28 and B66 are supported and have been also certified so far.
Loop One uses NB-IoT with radio, which is the best in class-leading Low Power Wide Area (LPWAN) technology, addressing the LPWAN requirements of the Internet-of-Things (IoT).
NB-IoT is characterised by: excellent indoor coverage, support of a massive number of connections, cost efficiency, low device power consumption and optimised network architecture. NB-IoT penetrates deep underground and into enclosed spaces providing 20+dB coverage indoors. NB-IoT also offers well enough bandwidth for devices sending and receiving data, 24 kbps DL /15.625 UL, which is important to Over-the-Air (OTA) upgrade feature, for example.
The underlying NB-IoT technology offers the same tried and true security and privacy features of LTE mobile networks, including IoT device support for: user identity confidentiality, entity authentication, data integrity, and mobile device identification.
Long-lasting and rechargeable
We guarantee 6 months of continuous operation with a single charge.
Bio-based Loop One covers
We are manufacturing Loop One smart sensor’s covers out of injection moldable biocomposite. This means that up to 50% of the cover material consists of locally sourced timber. This new and sustainable material guarantees technically excellent parts that are not only durable and precise, but also environmentally friendly and soft to touch.
