Comprehensive Coverage: LoRa1120 Module Supports Satellite Communication and Multi-Band Transmission
LoRa1120 adopts Semtech's LR1120 chip, an ultra-low-power module designed specifically for global geolocation applications. It supports multi-band LoRa and long-range frequency hopping spread spectrum (LR-FHSS) communication, operating in the sub-GHz and 2.4GHz industrial, scientific, and medical (ISM) bands, as well as the S-band authorized for satellite communication. The module integrates a cloud-native multi-constellation Global Navigation Satellite System (GNSS) scanner and a passive WiFi MAC address scanner, both of which are serviced through Semtech’s LoRaCloud™. The LR1120 complies with the physical layer requirements of the LoRaWAN standard specification released by the LoRa Alliance while maintaining configurability to meet various application and proprietary protocol needs.
Key Features of the LoRa1120 Communication Module
Multi-Band Support and Positioning Technology
Multi-Band Capability: Supports sub-GHz bands (433/470/868/915MHz), 2.4GHz, and the licensed S-band (1.9GHz–2.2GHz) for satellite communication.
Low-Power Positioning Technology: The LoRa1120 integrates both GNSS scanning and Wi-Fi scanning as low-power positioning methods, enabling accurate location tracking in various environments while maintaining low power consumption.
Positioning System Support
LoRa1120 not only supports GPS and BeiDou systems but also provides a hybrid low-power positioning solution by combining GNSS and Wi-Fi scanning, enhancing positioning accuracy and energy efficiency in IoT applications.
Terrestrial and Satellite Communication
A key advantage of the LoRa1120 is its seamless connectivity with both terrestrial and satellite communication networks. Leveraging LoRa’s ultra-low power technology, the module can operate for several years without frequent charging, and the positioning computation is performed in the cloud.
Data Transmission and Combination Modes
The LoRa1120 module offers flexible data transmission options, allowing users to choose different combinations based on actual needs:
Sub-GHz + 2.4GHz Combination: Ideal for hybrid applications requiring both long-range and short-range communication.
Wi-Fi + 2.4GHz Combination: Suitable for short-range applications that demand quick response.
Sub-GHz + GNSS Combination: Delivers optimal performance in scenarios requiring remote positioning and data transmission.
After receiving satellite or Wi-Fi data, the LoRa1120 module can transmit the information via the 2.4GHz wireless channel or the S-band.
Selection of Different Wireless Connection Methods
Based on Communication Distance and Data Volume
LoRa1120 supports multiple wireless connection options, and the choice depends on factors such as communication range, data volume, and response speed:
Sub-GHz Band: Suitable for applications requiring long-distance communication, wide coverage, and low data throughput. In such scenarios, the Sub-GHz band offers strong signal penetration, making it ideal for long-range transmission.
2.4GHz Band: Best suited for scenarios that demand real-time response, fast sensing, or quick control. It offers higher data rates and lower latency, making it ideal for short-range, high-frequency communication needs.
How to Select LoRa1120 Functional Combinations Across Different Application Fields
The choice of LoRa1120's functional combinations primarily depends on positioning needs and the characteristics of the application environment:
Remote Areas such as Oceans and Deserts: When satellite communication is required, the S-band is the optimal choice. It supports global positioning and is well-suited for environments with no network coverage.
Ports, Vessels, and Global Logistics: The 2.4GHz band is recommended due to its global compatibility, making it suitable for various regions and avoiding compatibility issues associated with regional Sub-GHz standards.
Low-Power Positioning Requirements: Retaining GNSS and Wi-Fi scanning technologies is ideal for IoT applications that are sensitive to power consumption.
The LoRa1120 wireless communication module features a multi-protocol, low-power RF chip integrating multiple modulation schemes including LoRa, FSK, and LR-FHSS. It supports global Sub-GHz bands, the 2.4GHz ISM band, and the 1.9–2.2 GHz satellite S-band, offering the combined advantages of wide-area coverage and high reliability.
