Introduction
|
|
The performance of wireless communications networks depends on an
efficient architecture of the network. Not only the coverage planned
with path loss propagation models
is relevant – also the behavior of the users and the traffic generated
by these users.
AWE
Communications offers therefore very sophisticated tools for the
planning of wireless communications networks. Coverage, data
throughput, interference and blocking can be predicted based on the
path loss predictions obtained with ProMan or other prediction tools.

Air Interfaces

WinProp offers some pre-defined network planning modules for the
following wireless standards:

___

.... more on request
as it is easily possible
to adapt the parameters of the wireless standard to arbitrary
standards. Either the user can do this via dialogues in WinProp or AWE
can do it. Please contact
the support team of AWE Communications if you need more information
related to the air interfaces.

The static simulators for network planning are able to predict:
- Cell
Assignment (Best Server,...)
- SIR /
SNIR
- Co-channel
interference incl. adjacent
channel interference
- Co and adjacent channel interference and noise
- Superposition
of carriers (especially for broadcasting networks and/or repeater
networks)
- Coverage
and number of received sites/transmitters/carriers/channels
- Required
Tx power of MS (per pixel and service) and BTS
- Max achievable data rates
- Handover maps
- Neighbor lists
|
|
With the dynamic system
simulators it is additionally possible to predict:
- Blocking
probability
- Traffic
throughput (Calls and also data depending on the data rate)
- Data
throughput for systems with adaptive data rates
- Mobility
and handover regions
- Packet delays (if packet services)

ProMan includes a static simulator and a dynamic simulator. The
static
simulator can ba applied to all air interfaces while the dynamic simulator
is currently focused on 3G and B3G
networks (but can be extended to other
air interfaces if required for customers).
All information required for network simulations can be edited in the
ProMan GUI or can be imported via an XML and CSV interface from other
network planning tools. The following tools are currently supported:
- Aircom Enterprise
- NSN (Nokia Siemens Networks) NetAct
- MSI Planet
- Agilent Wizard

ProMan needs the folowing information
for the
computation:
- Specification
of the air interface (bandwidth, link budget, sensitivity of BTS, Max.
MS power,...). Air interfaces with variable and adaptive net data rates
(UMTS, GPRS, EDGE,...) can be considered. Criteria for the
adaptive selection of data rates can be defined, based on the path
loss, delay spread, and CIR predictions
of ProMan or other prediction tools.
Most relevant air interfaces are already pre-defined (see list above).
- Defintion of transmitters (base stations) -
including location, antenna pattern and TRX capabilities
- Path loss predictions (computed in
ProMan or
imported from prediction tools)
- Traffic
(Arrival rate & hold time for each considered service)
Two options: Either homogenous distribution of the traffic or location
dependent traffic (Graphical traffic editor based on building or
clutter
databases).
- Dynamic
system simulator needs additionally link level simulations
for the simulation of packet switched traffic.

All
network planning modules are either integrated in the GUI of ProMan or
available as
modules or plug-ins for all common operating systems and platforms!
The graphical user interface (GUI) of ProMan
runs on all Windows™
Vista/XP/2000/NT4/ME/98/95™ and with emulators also on UNIX™ platforms.
