Supported Analyses:

ComSiteDesign (CSD) allows RF engineers to perform a wide variety of analysis such as:

RF Coverage Analysis with Coverage Summary

CSD produces detailed RF Coverage Analysis based upon the propagation parameters selected. In addition, CSD will create a coverage summary report compatible with Microsoft Word that includes items such as:

•  Plot description
•  Signal Strength Bins
•  Site-independent parameters
•  Site Details
•  Coverage area table

Best and Second Best Serving Site

Within CSD, RF Engineers can select any location (pixel) where signal coverage is shown, and the tool will show which site is the strongest and second strongest site, sector and/or transmitter.

Reverse link best server (Talkback analysis)

When this analysis is selected, only the sites with active receivers will be analyzed and therefore only sites with active receivers are shown. This analysis shows the strongest receiver from a selected location.

Co and Adjacent Channel Interference

This analysis is performed when assessing the degree of interference offered as a result of using the same frequencies at different sites in the signal area.

Multi-Site/Multi-Signal/Multi-Channel Analysis
Simulcast Distortion (Time Delay Interference)

In order for RF Engineers to minimize the possibility of time delay interference (referred to as simulcast distortion), carrier levels, modulating signal levels and transmission launch times need to be appropriately set. CSD estimates the degree of interference by comparing the relative arrival times of signals from every site in the network and computing their relative signal strengths. This allows RF Engineers to determine primary sites involved in creating the expected distortion and to adjust settings to minimize that distortion.

Frequency Assignment (manual)

RF Engineers can manually assign frequencies at any time.

Contour Analysis

At times it is desirable to represent coverage in terms of contours, particularly when mitigating potential regulatory violations or for showing progress in meeting the network's construction guidelines in terms of population coverage. CSD allows you to represent coverage in terms of contours.

Automatic Frequency Assignment and Planning

ComSiteDesign's optional Automatic Frequency Planning (AFP) module is used to assist with the task of creating, modifying and fine-tuning the assignment of frequencies to transmitters (sectors) in a cellular network. Using a sophisticated optimization technique referred to as simulated annealing the CSD AFP identifies an optimal channel plan such that co-channel and adjacent interference is minimized. The AFP, the channel assignment and the propagation modules of ComSiteDesign form an integral set of tools that assist in the creation of frequency plans for interference limited frequency reuse wireless networks.

Point-to-Point Microwave

CSD allows engineers to perform radio path analyses. A RF Engineer may define a path profile between any two points to determine if the path is obstructed or non-obstructed by considering earth curvature, Fresnel clearance and clutter (obstacle) heights. Further, CSD includes an optional module LATIS (Link Analysis for Interconnecting Sites) which provide for optimal calculation of antenna installation heights as well as computing the link outage probability inclusive of rain attenuation as per ITU recommendations.

Quality Reporting

CSD generates detailed coverage and analytical reports compatible with MS Word. The reports include a summary to the equipment configured at each site, propagation model assumptions, demographic (population) based statistics and area coverage relative to predefined boundaries. Depending on the end-user's options ordered the reports may include:

•  Handoff (hard and soft handoff)
•  Contours
•  Best server
•  Carrier to Interference
•  Adjacent channel interference
•  Simulcast distortion
•  Server count distribution
•  Pilot channel Ec/Io best server
•  Reverse traffic best server -BER
•  Forward Traffic Eb/Nt - Best Server
•  Number of subscribers covered by County and/or Postal code
•  Wireless Access Point (WAP) to Pole0mounted Microcell
•  Wireless network interconnect
•  Amount of traffic offered
•  Amount of traffic rejected
•  Number of channels required by sector
•  Percent of area covered by signal bin
