ComSiteMPE Functional Overview
ComSiteMPE is an engineering software tool for evaluating non-ionizing radio frequency(RF) emissions and predicts the Maximum Permissible Exposure (MPE) potential tohumans at or near wireless communication sites. The predicted RF emissions areevaluated against acceptable MPE limits as defined by specific established Standards. Theanalysis then suggests if the communications site is in compliance with these Standardsregarding safe human exposure to radio frequency radiation.
The analysis considers all RF signals emanating from wireless communications systemantennas defined by the user. These antennas can be located on communication towers,
rooftops, poles or other types of antenna mounting structures.

Radio Propagation Model Calibration, Mapping and Measurement Data AnalysisWith the ComSiteDesign Wireless Network Engineering Software
Introduction: ComSite Design (CSD) provides the means of maximizing the accuracyof its propagation models with the use of field gathered measurement data. In manyinstances the standard deviation of the difference between the measured and computedpoints can be below 7dB. This process involves an iterative method of collecting field-measured data, extracting the possibility of outlying samples resulting for erroneous GPSreadings attributed to multi-path and/or poor HDOP (Horizontal Dilution of Precision).
Depending on the ultimate goals of the test, the measurement equipment typically used in
gathering the test data may consist of:
A fast scanning receiver preprogrammed with the networks control channelfrequencies and/or primary channels in use or
Temporary (clear) channel(s) to minimize the extent of co-channel and/oradjacent channel interference,
A test transmitter calibrated for at least 10 to 20W of output power,
A known reference antenna and measured cabling losses.
1. Planning the Test Route
Prior to conducting a measurement campaign it is of the utmost importance that and aplanner:
a. Record the height of the reference antenna. Do not collect measurements if this information is not known.
b. Record the ERP (Effective Radiated Power) and antenna type of the referencemeasurement site. Do not collect measurements if this information is notknown.
c. Record the coordinates of the reference site to be calibrated.d. Plan your test route(s) before going on the field. Do not collect measurementswithout planning your test routes.
e. Create a Reference Calibration site in CSD for the target area or market.f. Establish a reasonable radius of the site to be surveyed. This radius will
depend on the type of site ERP and frequency The user may run CSD at 50%

serving sectors clutter type mix. Note that calibration measurements may betaken with the presence of a continuous CW (continuous carrier wave) signaland, for example, a fast scanning receiver or spectrum analyzer. A radio orwireless modem that provides an RSSI (Received Signal Strength Indication)in an automated fashion may also be used.
i. Establish the approximate area for each clutter type in the test area, i.e, A1 isthe area for dense urban, A2 is the area for urban, etc. Calculate the clutterlosses using the CSD summary report the total (un-calibrated) coverage area,
and sector under test, call this total area A. j. Then, N(A1/A)= the minimum number of test points for clutter/land-use areaof type one, N(A2/A)= the minimum number of test points for clutter area of type two, and so on. This should provide the planner a statistically soundmethod on how to distribute the test locations within a survey area. It is alsogood practice to distribute the measurements as evenly as practically possiblewithin each clutter type.
2. CSD Propagation Model Calibration Procedure
To begin thecalibrationprocedure, definethe site location forthe area testedaccording to thesteps described insection 1. As asimple convention,name the site orassign a site ID orlabel that identifiesthe site as thereferencecalibration site forthat given area,environment,market or mix of

Click on the File Select button to import the measurement data file collected in the field.To view the measurements follow the measurement import procedure described hereinand use the control window shown in Fig. 2.9 .
Fig. 2.9
Once the measurements are imported, CSD will automatically update the radio coverage.It is suggested that the calibration of all reference sites be done without accounting foradditional log-normal and multi-path fading margins. To do so set the reliabilityparameters in CSDs propagation parameters window to 50%. An example un-calibratedsite compared to measurements collected in the field is shown in Fig. 2.10 .
In many instances, depending on the complexity of the environment surrounding the testbase station site, an un-calibrated coverage will appear greatly different than themeasurements as suggested in Fig. 2.10 .

verify that there is a close correlation between the general shapes of the two graphs (redis measured data and blue is computed signal). That is, there should generally beinstances where the measured signal level drops the computed data should drop as well.Similarly if the measured values rise the computed signal level should rise as well. If thiscorrelation exists it is indicative that theres a good correspondence between the
