Abstract


One of the major topics of machine-to-machine

(M2M) communications are reliable data links in the license free

ISM/SRD bands. To design such low power wide area (LPWA)

systems which work in applications like smart metering, smart

grid or Industry 4.0 a basic knowledge of the propagation channel

characteristic of that bands is essential. With respect to findings

from our previous works, the emphasis of this investigations

is the frequency selectivity of propagation channels. Here we

present the first results of field trials in urban and commercial

area environments for the 868 MHz ISM/SRD band. To make

multipath effects plausible for the frequency selectivity, we take

the topographic conditions into account. Our findings show that a

large number of propagation channels in the 868 MHz ISM/SRD

band are affected by strong multipath fading and can classified in

different categories. In this context the major multipath param-

eters depend in a plausible way on the topographic conditions

of environment. The temporal evolution of the parameters show

strong correlation of successive days for propagation channels

with mainly outdoor parts. In contrast, the multipath parameter

for primarily indoor propagation channels show fluctuations over

weekdays.
