Define a wireless air interface for radio network planning.
Air Interface Definition
The definition of a wireless air interface is mandatory for radio network planning.
You have to either select a predefined air interface file
(.wst) or define an individual air interface.
CAUTION: Defining an individual air interface is an advanced feature and
is only recommended for experienced users.
It is also possible to modify
a predefined air interface in ProMan during the
planning process.
Tip: Click File > New Project and from the drop-down list, select
Network Planning based on description file for air
interface.
If you select Network Planning based on description file for air
interface, you must specify the interface definition
(.wst) file. In addition, you must select the
Scenario such as indoor or urban and specify the geometry
database.
Included Air Interfaces
The performance of wireless communication networks depends on the efficient
architecture of the network. Due to the wide range of available air interfaces for
cellular and broadcast wireless networks (with their different behavior and
parameter settings), radio network planning is essential to analyze the performance
of the wireless network.
The air interfaces included in the installation include 2G, 2.5G, 3G, LTE, WLAN,
WiMAX, TETRA, and other networks. Network simulations are based on the wave
propagation results of the transmitters within the network and the definition of the
wireless air interface (Figure 1).Figure 1. Network simulations use the results from the per-transmitter propagation
simulations.
The propagation simulations produce per-transmitter power coverage. In conjunction
with the air interface and other simulation parameters, these form the input of the
network-planning module. One important output is the
signal-to-noise-and-interference ratio (SNIR). Received power and SNIR tend to
determine whether communication in a particular mode is possible or not. Several
other relevant outputs include, for example, maximum data rate, maximum throughput,
and cell assignment, see Figure 2.Figure 2. Network simulations use the results from the per-transmitter propagation
simulations.
All settings and parameters of a defined air interface can be exported to a wireless
standard file (.wst file). This makes it possible to store the
complex collection of parameters to re-use them for the creation of a new network
planning project.
Tip: Click File > Export > Export Air Interface Properties (*.wst) to export an air interface.
