The LR1120 is an ultra-low power, long range multi-band LoRa®
transceiver targeting geolocation applications. It integrates a long
range LoRa® modem, a multi- constellation global navigation
satellite system (GNSS) scanner, and a passive Wi-Fi® Access Point
MAC address scanner.
For LPWAN use cases, the LR1120 supports LoRa and (G)FSK
modulation on both sub-GHz and 2.4GHz bands, Sigfox®
modulation on sub-GHz bands, and Long Range Frequency Hopping
Spread Spectrum (LR-FHSS) on sub-GHz and 2.4GHz ISM bands, as
well as L (1.525-1.660GHz) and S (1.9-2.1GHz) bands for direct
satellite communications.
The LR1120 complies with the physical layer requirements of the
LoRaWAN® specification released by LoRa Alliance®, while
remaining highly configurable to meet different application
requirements and proprietary protocols.
The transceiver is suitable for systems targeting compliance with
radio standards including but not limited to ETSI EN 300 220, FCC
CFR 47 Part 15, ARIB, and Chinese regulatory requirements.
Besides world-wide sub-GHz and 2.4GHz communication
capabilities, the very-low power multi-band front-end is capable of
acquiring several signals of opportunity used for geolocation:
• 802.11b/g/n Wi-Fi Access Point MAC addresses
• GNSS (GPS, BeiDou, geostationary) satellite signals
Acquired information is transmitted over an LPWAN network to a
geolocation server. The geolocation server analyses the signal
information and calculates the LR1120's position with data from a
geolocation database, enabling a valuable balance between low
power and performance.
The LR1120 geolocation capability is further increased by
Bluetooth® Low Energy beaconing compatibility to allow indoor
and outdoor geolocation use cases, as well as a powerful sub-GHz
ranging engine for localization and recovery of lost assets in
logistics applications.
