1. The document discusses various practical considerations for implementing a LoRaWAN network including choosing antennas, cables, frequencies and LoRa modules based on factors like SWR and internal circuitry. 2. It also provides information on developing LoRaWAN nodes using libraries like LMIC and decoding LoRaWAN packets by analyzing the PHYPayload, FHDR, FPort and other fields. 3. Recommendations are given on starting a LoRaWAN learning journey including suggested hardware, software and costs starting at around $200.
