The GPS almanac is a data set that includes information about the state of the entire GPS satellite constellation, as well as coarse data on every satellite in orbit.
- AppKey¶
The
AppKey
is an AES128 root key specific to an end device. Whenever an end device joins a network via over-the-air-activation(OTAA), theAppKey
is used to derive theNwkSKey
andAppSKey
session keys (specific to that end device) to encrypt and verify network communication and application data.- application server¶
The server that handles the LoRaWAN® application layer. It implements all user application logic, interfaces with the LoRaWAN® network server to receive uplink payloads and generates downlinks to be sent.
- Claim¶
The process of associating a device with an owner.
- Clock Sync¶
- Clock Synchronization¶
LoRa Cloud™ Service that performs the function of synchronizing time with an end device using LoRa Basics™ Modem device management frames.
- device application¶
The firmware that performs the primary functions of a network device, including data collection, actuation, and data exchange with the application server.
- Device Management¶
Service provided by Semtech’s LoRa Basics™ Modem and LoRa Basics™ Modem-E and the LoRa Cloud™ Modem & Geolocation Services to remotely manage an end device.
- DM frame¶
- Device Management frame¶
A LoRaWAN® network data frame containing Device Management data that is sent to
FPort
199 by default.- downlink¶
- downlinks¶
Message(s) from the Network Server or the Application Server to the end device.
- end device¶
Object with a LoRa™ chipset connected to a LoRaWAN® network.
- GNSS¶
- Global Navigation Satellite System¶
A constellation of satellites providing signals from space that enable the calculation of a position and precise time of day by a receiver.
- join server¶
A server component in a LoRaWAN® network that manages and delivers keys in a highly-secure manner, so that a device’s root key is never exposed. More details are available in the documentation for Semtech’s LoRa Cloud Join Server.
- LFU¶
- Large File Upload¶
One of the LoRa Cloud™ Modem & Geolocation Services used to reliably transfer one buffer of data at a time, abstracting the underlying network layer and protecting against packet losses. For more information, see the Large File Upload chapter.
- LoRa Basics™ Modem¶
- LoRa Basics Modem¶
LoRa Basics™ Modem includes a modem and services from Semtech designed to operate on a LoRaWAN® network. It includes services running on the microcontroller of an end device. C code is available on Github.
- LoRa Basics™ Modem(s)¶
- LoRa Basics Modem(s)¶
Semtech’s modem portfolio, currently LoRa Basics™ Modem and LoRa Basics™ Modem-E.
- LoRa Basics™ Modem-E¶
- LoRa Basics Modem-E¶
LoRa Basics™ Modem-E is a Semtech modem and services running on the LR1110 chip and designed to operate on a LoRaWAN® network. Detailed features and description are available in the LoRa® Developer portal.
- LoRa Cloud Services¶
Semtech’s simple cloud API that can be easily integrated with a LoRaWAN® network or application server to enable LoRaWAN® device provisioning and determining the location of any LoRa-based device. The LoRa Cloud Geolocation Solver can resolve GNSS, Wi-Fi, or radio (RSSI/TDOA) requests. The Geolocation Solver is available with a pay-per-call pricing model.
- LoRa Cloud™ Modem & Geolocation Services¶
- LoRa Cloud Modem & Geolocation Services¶
Semtech’s simple cloud API that can be easily integrated with a LoRaWAN® network or application server to enable estimating the location of any LoRa-based device. The LoRa Cloud Modem & Geolocation Service can resolve GNSS, Wi-Fi, or radio (RSSI/TDOA) requests. Geolocation services are available with a pay-per-call pricing model.
- LoRa Edge Asset Management Platform¶
A collection of hardware and software solutions for implementing asset tracking.
- LoRaWAN®¶
- LoRaWAN¶
A specification for a low power wide area network that uses Semtech’s LoRa radio modulation.
- LoRaWAN® network server¶
- LoRaWAN network server¶
The device management and routing server for a LoRaWAN® network.
- LPWAN¶
Low Power Wide Area Network.
- LR1110¶
Semtech LoRa transceiver with low power geolocation features. The LR1110 chip can be used as a transceiver or flashed with modem firmware. For more information, see Semtech’s product page.
- MCU¶
- Microcontroller Unit¶
This is where the end-device application runs on an end device.
- MIC¶
- Message Integrity Code¶
In LoRaWAN® context, this is the 4 MSB output of an AES-CMAC operation. It is appended to avoid packet tampering.
- MTU¶
- Maximum Transmission Unit¶
The amount of data that can be transferred at a time. LoRaWAN® is a variable MTU protocol.
- NAV message¶
A message generated by the LR1110 chip for the device application after a GNSS scan.
- OTA¶
- Over-the-Air¶
An action performed via radio communication.
- POR¶
- Power On Reset¶
An automatic systematic reset performed when the device is powered up.
- ROSE¶
- Reliable Octet Stream Encoding¶
One of the LoRa Cloud™ Modem & Geolocation Services. It is used to reliably transfer streams of data, abstracting the variable MTU and protecting against packet loss. For more information, see the ROSE page.
- RSSI¶
- Received Signal Strength Indicator¶
A numerical indicator of the power level received by a device. It can be used for approximating distance.
- RTC¶
- Real Time Clock¶
Dedicated module to keep accurate time. Real Time Clocks are usually embedded inside microcontrollers, however, they can also be dedicated modules.
- TDOA¶
- Time Difference Of Arrival¶
A technique used to calculate the position of a device by precisely time-stamping the reception of a device packet on several spatially-diverse receivers.
