SNIR targets must be
fulfilled in each receiver to obtain a good signal quality (low BER).
To determine the SNIR, WinProp superposes
- thermal noise (depending on the bandwidth of
- CCI (co-channel interference (from other
transmitters radiating on the same carrier frequency)).
- ACI (adjacent channel interference (from other
transmitters radiating on the adjacent carrier frequency)).
The user can display all locations where the SNIR is sufficient for a
good reception of the signal and the user can visualize all areas where
the signal quality is reduced because of the low or even negative SNIR.
WinProp can model an arbitrary number of types of mobile stations (e.g.
handsets, notebooks, vehicular terminals,...) and all of them with
their individual SNIR targets, noise figures, general losses, fast
fading margins,.....The mix of mobile stations (e.g. 50% handsets, 30%
vehicular, 20% notebooks) can be defined as well by the user.
Of course,for multi service analysis (e.g. speech and data with
different SNIR targets and capabilities of the user terminal)
individual outputs are computed for each service. During the planning
process the user can already analyze at which location which service is
For each service the target SNIR as well as the min. required signal
level can be defined individually (including different values for up-
and downlink and different types of mobile stations with different
