LoRa M.O.S.T.


Dual-mode Compact RF Module for LoRa® Technology

The GlobalSat LM-533H is a RF module that based on LoRa® technology which provides long-range, low data rate IoT connectivity to sensors, electronic meter reading, geolocation devices, industrial monitoring and control, home and building automation, long range irrigation systems, and all kinds of IoT/ M2M equipments. It can works as the end-node devices in the LoRaWAN™ infrastructure or in GlobalSat proprietary ecosystem (MOST-Link).
  • Built-in standard LoRaWAN™ FW and proprietary MOST-Link FW in the same module
  • Share same PCB/ device design for both LoRaWAN™ and private RF data communication
  • Compact size, only 12x13 mm
  • Ultra-high sensitive receiving ability by LoRa® spread spectrum modulation technology
  • Long-distance transmission (1KM to 10KM)
  • Instant wake up over the air
  • LoRa® / FSK/ GFSK/ OOK modulation, 2-way half –duplex communication, strong anti-interfere
  • Maximal output power 100mW (20dBm), output power adjustable between 5-20dBm
  • Easily use, auto exchange on communication & transceiver
  • Tuning free
  • Accord FCC, ETSI, TELEC standard
