There are three types of NORVI Expansion modules are available as follows;
LoRa communicaon module with the RYLR896 transceiver provides ultra-long range spread spectrum communicaon and high interference immunity whilst minimising current consumpon. The module is cerfied by NCC and FCC.
Nb-IoT communicaon module with the BC95-G provides ultra low power communicaon interface for NORVI controllers. The module supports the global bands making it applicable around the world with a super high sensivity.

Coverage and Range: LoRa (Long Range) technology excels in providing long-range communication capabilities, making it ideal for projects that require connectivity over large distances or in areas with limited infrastructure. NB-IoT (Narrowband IoT) operates on existing cellular networks and offers better coverage in urban areas but may have limitations in remote or rural locations.
Power Consumption: NB-IoT typically consumes less power compared to LoRa, making it suitable for battery-operated devices or applications where power efficiency is critical. LoRa, on the other hand, is more suitable for applications where power consumption is less of a concern, but long-range communication is essential.
Data Rate and Bandwidth: LoRa provides higher data rates and bandwidth compared to NB-IoT, allowing for faster transmission of large volumes of data. If your project requires high-speed data transfer, LoRa may be the preferred choice. However, NB-IoT’s lower data rates are often sufficient for applications that involve periodic transmission of small data packets, such as sensor readings.
Cost: LoRa modules and infrastructure may have lower upfront costs compared to NB-IoT, as LoRa operates on unlicensed spectrum, reducing the need for expensive cellular subscriptions or infrastructure. Analog input expansions, depending on the specific components and implementation, can offer a cost-effective solution for projects with simpler requirements or budget constraints.
Interference and Regulation: LoRa operates in the unlicensed ISM (Industrial, Scientific, and Medical) bands, which may be susceptible to interference from other devices operating in the same frequency range. NB-IoT operates on a licensed spectrum, providing better immunity to interference but requiring compliance with cellular regulations and potential subscription costs.
Sensor Compatibility: Analog input expansions allow for direct interfacing with analog sensors, making them suitable for projects that require integration with a wide range of analog sensors without the need for additional digital conversion hardware. However, LoRa and NB-IoT modules may require additional sensors or interfaces to connect to analog sensors, adding complexity and cost.
