Lora Gateway RF band survey application
========================================
1. Introduction
----------------
This software is used to scan the RF band and measure background RSSI and some
measurement of interferer pattern.
The RSSI is purposefully skew towards high values, to detect high power
interferers (eg. a gateway installed in the beam of a powerful base station),
and not to characterize the noise floor, or accurately measure the time-domain
profile of interferers.
2. Dependencies
----------------
This software call functions in the loragw_reg and loragw_reg sub-modules of
loragwlib. loragw_spi is used indirectly, and the loragw_hal sub-module is not
used at all, except for constants define at the top level.
It has been qualified with the Lora Getway HAL library version 1.0.0, and should
be compatible with any compatible later version that use the same API, or a
downward-compatible one.
Because some non-public functions from loragw_hal had to be re-implemented, any
change in the IP might affect this program even if an updated Lora Getway HAL
library is provided.
Connecting an incompatible concentrator board should give you the error:
"ERROR: fail to connect to concentrator board"
3. Usage
---------
To stop the application before the end of the measurement, press Ctrl+C.
By default, the program scans the whole band (start and stop frequency defined in
the loragw_hal.h file) with a 200 kHz measurement step.
Use -f option to change start and stop frequency, and measurement step.
The resolution bandwidth of the scan is 200 kHz and cannot be set by the user.
The measurement results are put in a CSV file whose name include a UTC timestamp
of measurement starting time in ISO 8601 recommended compact format:
yyyymmddThhmmssZ (eg. 20131009T172345Z for October 9th, 2013 at 5:23:45PM UTC)
