|Base station Name|
|Base station Model|
Long-Range Relay Universally Unique Identifier, that is the base station Universally Unique Identifier. The base station Universal Unique Identifier (LRR UUID) is a concatenation of LRR OUI and LRR GUID.
<LRR-OUI> is the IEEE OUI of the base station vendor (6 hexadecimal characters).
<LRR-GID> is the base station identifier relatively to the vendor (allowed characters: [0-9][a-z]-_, max 256 characters)
Kerlink: <LRR-GID> = full eth0 MAC address
Cisco: <LRR-GID> = full Cisco S/N
Base station network Identifier allocated by the network and unique within the network.
Base station network Identifier, unique within the network (allocated by network).
LRR ID (32 bits) is automatically generated and dynamically associated with the LRR.

|Advanced geolocation configuration|
The following parameters must be configured in order to improve the network geolocation:
RF antenna configuration:
RF antenna position (latitude/longitude): Exact position of the RF antenna. This information is particularly required when the RF antennas are installed few meters away from the base station box. If not specified, the base station position is used.
RF antenna altitude above sea level (in meters): indicates the vertical distance between the WGS84 reference ellipsoid and the cable connector on the antenna.
RF antenna height above the ground level (in meters): indicates the vertical distance between the ground and the cable connector on the antenna.
RF antenna cable delay (in nanoseconds), this information could be either derived from field measurements or directly estimated from the cable’s electrical specification provided in its datasheet.
GPS antenna configuration:
FPGA board fine timestamp decryption key:
License key allowing the base station software to read high precision timestamps. These timestamps are used to enhance the devices' geolocation. Contact your base station vendor to obtain this key.
This decryption key is specific to each LoRa® board; it is delivered by Semtech (the LoRa® chip manufacturer).

|Spreading Factor (SF)|
Signal to Noise Ratio
Determines the ratio between the received LoRaWAN® signal strength of the desired signal and the signal strength of the background noise. Unlike conventional radio technologies, LoRaWAN® reception does not require positive SNR, you may see correct reception of LoRaWAN® frames with negative SNR up to -20 dB (SF12).
|RSSI (Signal Strength)|
Received Signal Strength Indicator.
Determines the total received signal strength over a given Logical Channel, summing up both the desired signal and the background noise. When SNR is negative, this effectively measures the background noise.
Uplink Duty Cycle determines the aggregated effective reception time by the base station over a given channel for all received devices, over a time window (typically one hour). Due to ALOHA network technology of LoRaWAN®, Uplink Duty Cycle should stay below about 10%. Increase macro diversity by adding base stations, if the Duty Cycle gets above 10%.
Downlink Duty Cycle determines the aggregated transmission time of the base station over a given channel, over a granularity period (typically one hour).
A LoRaWAN® logical channel is characterized by its central radio frequency and bandwidth. For example, in ISM band eu868 profile default settings, LC1 refers to a center frequency = 868.1 MHz and a channel bandwidth of 125 kHz.
Simultaneous transmissions using different Logical Channels do not interfere with each other. Within a given Logical Channel, transmissions with different Spreading Factors also have a high degree of isolation.

Technique used to locate the base station.
Manual mode: the position of the base station is expressed by its latitude and its longitude that are manually set by the base station administrator.
Onboard Global Navigation Satellite System (GNSS) position (default position): the position of the base station is expressed by its latitude and its longitude, which is automatically reported by a GPS receiver located on the base station.
If the base station has a GPS receiver and can receive a stable GPS signal, the "Onboard GNSS position" mode should be used. Otherwise, the "Manual" mode should be used.
