Abstract


For many applications Low Power Wide Area Net-

works (LPWANs) are an appealing method to provide cost-

efficient connectivity to many small and battery-driven devices

spread over large areas. However, LPWANs are typically oper-

ated in the license exempt sub-GHz frequency bands. This means

they have to share the spectrum with other devices also operated

in these bands, which can impair the LPWAN signals. In order

to analyze the impact of interference on LPWAN signals the

IEEE 802.15 Interest Group LPWA has defined an interference

model that can be used for detailed Physical Layer (PHY)

simulations. In order to define suitable parameter sets for this

interference model we propose a processing framework based on

image processing. This framework allows a broadband analysis

of license exempt frequency bands. It is able to identify signal

parameters such as access length, arrival rate, center frequency,

and bandwidth. These obtained values can then be used as input

parameters of the IEEE 802.15 interference model or other

channel occupancy models. We present exemplary measurement

results that we obtained during a field trial as part of the so-

called Betriebs-Adaptive Tracking Sensorsysteme (BATS) project

in Berlin, Germany and show the derived parameter sets.
