The Network Design Module, an add-on module to
EDX® SignalPro®, gives you a feature-rich, carrier-class, wireless
network planning tool. It is ideal for all stages of network design –
from initial deployment through network maturity, with special
emphasis on automatic processes and capacity and interference issues.
Included in the Network Design Module is a specific feature set for
designing WCDMA/UMTS Systems. The Network Design Module also includes
specific feature sets for Multipoint Systems and Mobile and Nomadic
Systems. This document only covers the features that are specific to
WCDMA/UMTS systems.
Studies
Specialized Area-Wide Studies
In addition to the basic studies in EDX SignalPro®, the Network
Design Module offers technology-specific studies for WCDMA & UMTS
systems:
User-defined Area Studies
For complete flexibility, you can even design your own area study
analysis via an external DLL using a customized or proprietary study
algorithm. This advanced network design feature enables you tailor EDX
SignalPro as you need.
Traffic Loading
Calculate traffic loading on individual sectors based on real service
areas and a selection of multiple service types. You can generate a
report on sector loading or use the information for channel assignment
calculations.
Packet-Switched Traffic
Perform packet-switched traffic distribution with individual control
of multiple service mixes such as voice, e-mail, web browsing, audio
streaming, and video streaming.
Monte Carlo Analysis
A Monte Carlo analysis helps you determine loading and performance.
Random mobile placement is controlled by selected traffic
distribution. Loading limits are determined by total mobiles or
soft-blocking and disconnect rates. Adaptive antenna descriptions are
even considered in the analysis.
You can use the standard static Monte Carlo analysis to determine
system loading and performance. Loading limits are determined by total
mobiles or soft-blocking rates. Mobiles are placed according to the
selectable traffic distribution methods.
Features
System Operating Parameters
You have full control over system operating parameters including
handoff and all relevant CDMA parameters. Designing your system is
easy and intuitive.
Overlay Systems
It is easy to set up and study overlay systems with mixtures of
different technologies at each cell sector. With easy right-click
commands, sectors can be grouped together and activated/de-activated
for easy traffic planning and analysis in multi-technology systems.
Automatic System Layout
Automatically lay out your cell sites within your system using
criteria such as fixed hexagon grids with adjustable cell service
radius.
PN Offset
Comprehensive PN offset planning makes assignments to avoid co-offset
and adjacent offset conflicts using real sector service areas.
EDX 3D Pathloss Surface
Unique EDX® 3D “Pathloss Surface” approach explicitly stores sector
specific measured pathloss values instead of model prediction values.
Link Budgets
The Network Design Module is equipped with a quick and convenient link
budget spreadsheet that assists in determining the cell service radius
for a given service type (date rate) and service environment.
Propagation Models
In addition to EDX SignalPro’s selection of over 15 basic propagation
models, the Network Design Module includes sector-specific models that
can be “tuned” automatically or by manual adjustments to existing
coefficients. Also, point-slope models can be created with test-drive
data, and an external DLL link provides access to external propagation
models.
Antennas
Transmit and receive antennas can be specified as full 3D patterns.
Polarization, mechanical beam tilt and beam tilt azimuth can be
specified separately. Supports both co-polarized and cross-polarized
directional receive antennas.
Adaptive Antennas
EDX’s analysis can take into account adaptive “smart” antenna C/I
ratio improvements for transmitters and receivers using EDX’s
exclusive adaptive antenna Application Programming Interface.
Technologies
Neighbor Lists
Neighbor list calculations are included based on most likely server
and handoff criteria.
The following technologies are supported in any frequency band:
- W-CDMA
- CDMA 2000 (3XRTT)
- Evolving 3G technologies
Adaptive Modulation Types
Data rate and bit error rate studies consider adaptive modulations
schemes for the most refined study results. |
