Low-power long-range (LPWAN) solutions for IoT and M2M

Narrowband Fidelity

NB-Fi is an abbreviated Narrowband Fidelity. It is an innovative LPWAN technology which is designed ground-up for the low-power, wide-area, machine-to-machine communication. This open wireless protocol has been purpose-built to enable the most robust, reliable, and energy-efficient sensor communication with the using the narrow band approach.

NB-Fi is a full stack

NB-Fi LPWAN technology covering a full stack of OSI model layers from physical PHY to application APP (IoT Cloud).

Conversely, WAVIoT NB-Fi protocol innovation is built on the entire wireless hierarchy, going deep into the physical (PHY) and medium access control (MAC) layers, resulting in a robust, long-range wireless communications solution which can operate under the most challenging of RF environments.

NB-Fi has been sharpened with extensive practical experience and on the challenges that we meet in numerous use cases. It helps us to provide a reliable solution with extraordinary characteristics within a full stack of technology.

NB-Fi is smart LPWAN protocol

  • Smart spectrum utilization algorithm is highly optimized and have best in class spectral efficiency.
  • NB-Fi is based on narrowband RF approach wich is considered as the de facto standard for long-range communication.
  • Sophisticated mathematically based algorithms and SDR-technology allows processing a wide spectral band providing a capacity of 2 000 000 nodes for one base station.
  • High computational performance let us recover RF signal buried -3 dBm below the noise floor.
  • The use of sub-GHz frequency bands provides extraordinary penetration capabilities in a harsh urban environment versus 2.4 GHz technologies.

NB-Fi is open standard

NB-Fi is open wireless LPWA protocol suitable for worldwide deployment.

Open standard delivers sustainability to wireless technology and interoperability between different manufacturers. Open standard technology drives the innovation and cost-efficiency through the greater competition.

Getting access to all the NB-Fi technology allows to develop and sell your own IoT products that are compliant with NB-Fi standard.

Features & Benefits of NB-Fi

NB-Fi has been adopted for M2M connectivity, IoT applications and sensor networks worldwide. We took into consideration a myriad of factors to ensure compliance with the requirements of the real world conditions.

Icon License-free

License-free and frequency flexible solution is suitable for worldwide deployments, supporting radio hardware and compliant MAC architectures in 915 MHz and 868 MHz, as well as other sub-GHz license-free spectrum.

NB-Fi coexistance icon

Perfect coexistence. The gateways also run an interference avoidance algorithm that allows them to constantly monitor and avoid RF energy from other systems in the band.

NB-Fi long-range icon

Long range connectivity of 10 km in the city and up to 30 km in the countryside is available with highly reliable WAVIoT NB-Fi radio protocol.

NB-Fi high penetration icon

High signal penetrating power enables long range transmission from basements and through multiple concrete walls.

NB-Fi security icon

High level of security is ensured by encrypting bi-directional data from the endpoint throughout the data system with the XTEA-2 256 bit key.

NB-Fi multiprotocol equipment icon

Multiprotocol equipment. Gateways are fully SDR in both directions. It means we can start supporting new protocol by simple firmware update on the gateways.

NB-Fi scalability icon

High scalable due to each base station has an extensive capacity to operate more than 2 000 000 smart devices within its range.

NB-Fi API icon

Extensible API. The data flow may be easily integrated with the clients’ existing ERP / IT system or frontend through HTTPGet / APIs.

NB-Fi decentralized icon

De-centralized reliable architecture allows base stations to perform a significant portion of network processing internally, which allows the system to continue operating with full functionality through network blackout.

NB-Fi artificial intelligence icon

Artificial Intelligence. The NB-Fi technology uses neural algorithms and machine learning for network self-management minimizing human involvement and optimizing a dozen of network parameters automatically.

How far could NB-Fi reach

Just calculate and imagine how far could NB-Fi deliver your sensor data and how many kilometers you can cover with WAVIoT IoT Devices.
