First LoRa Plus transceiver with multi-PHY front end

Semtech has introduced the latest addition to its LoRa Plus lineup, unveiling the LR2021 transceiver as part of its fourth generation wireless technology designed for operation across multiple frequencies. This new chip is a significant advancement in the field of IoT connectivity, offering support for both terrestrial and satellite networks in the Sub-GHz, 2.4 GHz ISM bands, and licensed S-band within a single device.

The LR2021 transceiver is engineered to be backward compatible with previous LoRa devices, making it suitable for use with LoRaWAN networks while also incorporating physical layer modulation for fast long-range communication (FLRC). This feature opens up a wide range of possibilities for applications that require reliable and efficient data transmission over extended distances.

One of the key highlights of the LR2021 is its ability to support sensor data transmission for various applications, including but not limited to gunshot detection, glass break sensing, license plate recognition, and fall detection. Despite its advanced capabilities, the transceiver is designed to operate on small batteries for extended periods, ensuring long-lasting performance and reliability.

FLRC technology represents a significant leap forward in data transmission speeds, enabling the LR2021 to achieve data rates of up to 2.6 Mbit/s. This enhanced capability is particularly beneficial for applications that involve audio streaming and image transfers within the Internet of Things ecosystem, showcasing the versatility and adaptability of the LoRa protocol.

In addition to its impressive data rates, the LR2021 transceiver also offers support for a wide range of modulations, including FSK, OOK, O-QPSK, and LR-FHSS. This versatility allows the chip to seamlessly integrate with various protocols such as Meshtastic, W-MBUS, Wi-SUN FSK, and Z-Wave when combined with third-party stacks, further expanding its compatibility and applicability in diverse IoT scenarios.
