Glossary

  • ABP – Activation by Personalization
  • ADR – Adaptive Datarate
  • AES-128 – Advanced Encryption Standard 128-bit wikipedia
  • AppEUI – Application EUI, an 8-byte unique identifier for a LoRaWAN application
  • AppKey – Application Key, a 16-byte AES-128 key used in LoRaWAN to authenticate an end-device and derive session keys
  • Application Network – A set of gateways and end-devices configured to support a LoRaWAN application
  • Application Server – Entity in a LoRaWAN network tasked with managing the Application Session Key to decrypt uplink payloads and encrypt downlink payloads in packets
  • Application Session Key – A 16-byte AES-128 session key used in LoRaWAN to encrypt payloads between an application and end-device, derived from AppKey during OTAA
  • Bandwidth – Width of a LoRa transmission at 20 dB
  • Channel – Combination of LoRa datarate and frequency used for concurrent communications
  • Channel Plan – Set of supported datarates and frequencies for use in a LoRaWAN network according to regional regulations
  • Confirmed Packet – Packet requesting an ACK from the receiver
  • Custom Application – An application installed on a Conduit, can be used to receive LoRaWAN packets from the network server then process and/or forward to a remote server
  • Datarate – Combination of Spreading Factor and Bandwidth that determines the bit-rate of transmissions. Datarates can be used on the same frequency without interference. This creates virtual channels to reduce collisions.
  • DevEUI – Device EUI, an 8-byte unique identifier for a LoRaWAN device
  • Downlink – Packet sent from the gateway to an end-device
  • Downlink Counter – Session counter for downlink packets, 32-bit unsigned integer, 16-bits are sent with each packet
  • End-device – LoRa radio device expected to connect to the network and report
  • ERP – Effective Radiated Power wikipedia
  • EIRP – Effective Isotropic Radiated Power
  • EUI – Extended Unique Indentifier wikipedia
  • Frame Port – Optional 1-byte port value attached to packets, port 0 is used for sending mac commands in a payload, 1-223 can be used for application used. Values above 223 are reserved.
  • Frame Counter – 16-bit value attached to each packet as the least significant bits of the 32-bit uplink or downlink counter
  • Gateway – Component in a LoRaWAN network that receives packets from end-devices and forwards them to a network server
  • Hybrid Operation – US915 channel plan operating in an 8-channel mode
  • JoinEUI – Join EUI, an 8-byte identifier for LoRaWAN OTAA join requests
  • Join Accept – Message to end-device containing network information for an end-device, encrypted with AppKey, aka join response
  • Join Request – Message from end-device requesting to join a network, signed with AppKey
  • Join Server – Component in a LoRaWAN network that authenticates join requests and authors join responses using a unique end-device AppKey
  • LoRa – Low Power / Long Range, Digital spread-spectrum modulation technique used in Semtech SDR chips
  • Network Server – Component in a LoRaWAN network that maintains session information for communications with end-devices
  • Network Session Key – A 16-byte AES-128 session key used in LoRaWAN to authenticate uplink and downlink packets, derived from AppKey during OTAA
  • OTAA – Over-the-air Activation
  • OUI – Organizationally Unique Indentifer wikipedia
  • Spreading Factor – Amount of redundancy used in transmissions to extend the range of end-
    devices
  • Unconfirmed Packet – Packet not requesting ACK from the receiver
  • Uplink – Packet sent from an end-device to a gateway
  • Uplink Counter – Session counter for uplink packets, 32-bit unsigned integer, 16-bits are sent with each packet
