Introduction

The LR1110 is an ultra-low power platform that integrates a long range LoRa transceiver, multi-constellation GNSS scanner and passive Wi-Fi AP MAC address scanner targeting geolocation applications. The LR1110 supports LoRa, (G)FSK and Long Range-Frequency Hopping Spread Spectrum (LR-FHSS) modulation for LPWAN use cases. The device is highly configurable to meet different application requirements utilizing the global LoRaWAN standard or proprietary protocols. The LR1110 is designed to comply with the physical layer requirements of the LoRaWAN specification released by the LoRa Alliance. Besides the world-wide sub-GHz transceiver capabilities, the device features a very-low power multi-band front-end capable of acquiring several signals of opportunity targeting geo-positioning purposes: 802.11 b/g/n Wi-Fi Access Point MAC addresses GNSS (GPS, BeiDou, geostationary) satellite signals The acquired information is transmitted using a LPWAN network to a geolocation server. The position of the object is calculated by the geolocation server, which analyzes the transmitted information and correlates the position with data from a geolocation database, enabling a unique balance between low power and performance.

Features

• Worldwide frequency bands support in the range 150 - 960 MHz
• Low Noise Figure modes for enhanced LoRa/ (G) FSK sensitivity (differential input pins RFI_P/N_LF0)
• High power PA path +22 dBm (output pin RFO_HP_LF)
• High efficiency PA path +15 dBm (output pin RFO_LP_LF)
• Integrated PA regulator supply selector to simplify dual power +15/+22 dBm with one board implementation
• Able to support world-wide multi-region BOM, the circuit adapts to matching network to satisfy regulatory limits
• Fully compatible with the SX1261/2/8 family and the LoRaWAN standard, defined by the LoRa Alliance
• Long Range FHSS Transmitter, with intra-packet hopping capability
• 150 - 2700 MHz continuous frequency synthesizer range
• GPS/ BeiDou scanning (differential input pins RFI_P/N_LF1)
• Wi-Fi passive scanning (using input/output pin RFIO_HF)
• High bandwidth RX ADC (up to 24 MHz DSB)
• Digital baseband
• Two forms of voltage regulation (DC-DC or linear regulator, LDO) are available depending upon the design priorities of the application. DC-DC usage is recommended for power efficient operation with the cost of an extra inductor.
• Power On Reset (POR), Brown-out detection and Low Battery indication are supported
• Battery voltage measurement
• 32.768 kHz Low Frequency (LF) RC oscillator, optionally used by the circuit Real Time Clock (RTC)
• 32.768 kHz LF crystal oscillator (XOSC), used for RTC once/if available. It is also possible to use an external 32.768 kHz reference from the host, applied on pin DIO11.
• 32 MHz HF RC oscillator allowing configuration of the device without the need to start the main crystal oscillator
• 32 MHz HF crystal oscillator, HFXOSC, supplied from the LDO/DC-DC, used for radio operation. This main crystal oscillator is also used to calibrate the frequency error of t
