  • this module is based on semtech lorawan concentrator reference design -- sx1301 reference board- pcb_e286v02a. it is a high performance lora/lorawan module based on semtech sx1301 and sx1255/1257.
  • the sx1301 digital baseband chip is a massive digital signal processing engine specifically designed to offer breakthrough gateway capabilities in the ism bands worldwide. the lora concentrator is a multi-channel high performance transmitter/receiver designed to simultaneously receive several lora packets using random spreading factors on random channels. its goal is to enable robust connection between a central wireless data concentrator and a massive amount of wireless end-points spread over a very wide range of distances.
  • the sx1301 is a smart baseband processor for long range ism communication. in the receiver part, it receives i and q digitized bitstream from one or two receivers (sx1255 as an example), demodulates these signals using several demodulators, adapting the demodulators settings to the received signal and stores the received demodulated packets in a fifo to be retrieved from a mcu. in the transmitter part, the packets are modulated using a programmable (g)fsk/lora modulator and sent to one transmitter (sx1255 as an example). received packets can be time-stamped using a gps input.
  • the sx1301 has an internal control block that receives microcode from the mcu. the microcode is provided by semtech as a binary file to load in the sx1301 at power-on .
