Perform network analysis for a WiMAX air interface in a rural/suburban scenario for fixed communications, such as
“the last mile” to a residential internet subscriber.
WinProp is a complete suite of tools in the domain of wireless propagation and radio network planning. With applications
ranging from satellite to terrestrial, from rural via urban to indoor radio links, WinProp’s innovative wave propagation models combine accuracy with short computation time.
View the typical workflows when working with propagation simulations in specific scenarios, how to add a network planning
to a propagation simulation, include a receiver pattern, set up a time-variant scenario, include multiple-input multiple-output
(MIMO) at both the base station and the mobile station, connectivity analysis of sensor networks and optimization.
Use AMan to generate, edit and analyze a single antenna. Superimpose multiple antennas radiating similar signals to determine
the actual antenna pattern while taking into consideration the local environment.
WinProp includes empirical and semi-empirical models (calibration with measurements possible), rigorous 3D ray-tracing models
as well as the unique dominant path model (DPM).
In WinProp various air interfaces and applications are pre-defined: broadcasting, cellular, wireless access, WiFi, sensor networks,
ICNIRP and EM compliance.
Perform network planning for WiMAX in a rural mobile scenario.
WiMAX Standard and Definition
This is an example of the WiMAX air interface in a rural/suburban scenario for mobile
communications such as communication between base stations and vehicles. WiMAX
refers to the IEEE 802.16 standard - a family of wireless networks standards
formulated by the WiMAX forum. The IEEE 802.16e (mobile broadband wireless access)
Wimax standard is used in this model. WiMAX is similar to long-range Wi-Fi, but it
can enable usage at much greater distances.
Model Type
The geometry is described by topography (elevation) and clutter (land usage). The
database tree enables you to switch between the two displays.
Sites and Antennas
There are six antenna sites in this scenario. Each site has three sector antennas at
a height of 25 m.
Tip: Click Project > Edit Project Parameter and click the Sites tab to view the sites,
antenna patterns, and carrier frequencies.
The carrier frequencies are set to frequencies around 3.5 GHz.
Air Interface
The air interface is defined by a WiMAX wireless standard
WiMAX_Sample_Rural_Mobile.wst file. In this model,
orthogonal frequency division multiple access (OFDM/SOFDMA) is selected under
multiple access schemes, and time division duplex (TDD) is used for duplex
separation (switching between uplink and downlink).
Tip: Click Project > Edit Project Parameter and click the Air Interface tab.
Computational Method
The computational method is selected on the Computation tab.
The dominant path model (DPM) was selected for the computation. The
method focuses on the most relevant path, which leads to shorter computation
times.
Results
Propagation results show at every location the power received by a hypothetical
isotropic receiver from each transmitting antenna. Propagation results also include
field strength and path loss. Results are calculated for a single prediction plane
at 1.5 m height.
The type of network simulation used is a static simulation (homogeneous traffic per
cell). The network simulation calculates cell area, site area, best server, and
maximum data rate for both downlink and uplink. The network simulation also
calculates the minimum required transmitter power, reception probability and SNIR
(max) for all modulation and coding schemes used in this model for both downlink and
uplink. Various network results for the defined modulation schemes can be viewed
from Results: Network in the tree.
