Limitations of Tools

• Precision of results• Validity of assumptions?• Reliability of modeling?

• Tools need• Initial design proposal• Fundamental ideas• Creative thinking• User's intelligence

• There are no “self-configuring” tools• “garbage in - garbage out” rule applies strictly

Tools are just tools intelligence is yours!

• Global Positioning System• Based on a constellation of orbital satellites• CDMA coding of the signal, different codes for

civilian or military use• Precision:

• Accuracy of ca. 18m technically feasible• For civilians deliberately (!!) decreased to approx.

• 100m accuracy at 95% probability• 300m at 99.9% probability

• Used to get coordinates of visited sites during site surveys and locating measurements

• Watch out!!! Map datum and GPS datum must be THE SAME, otherwise bigger errors come out

GIS & Database ToolsMapInfo

• Graphic software to work with geographically referenced objects

• Objects organized in different layers to easily overlap/create different scenarios

• Main advantage for planning: possibility to easily display detailed information for sites within the corresponding map

• Possibility to import site information from Excel or CellTracker

• Easily customizable for other purposes:• SARFs• Visualising KPIs• Quality survey results


GIS & Database ToolsMapInfo


• Oracle-based database interface and documentation tool

• MapInfo can be linked via ODBC to CellTracker: • Possibility to compare the nominal site plan with the real situation on the field

• The safest way to share information about sites between RNP, TNP, SA, CW etc.

• Each user has its own account and read/write rights

• Issuing of customized reports, sorted by different site-related parameters

GIS & Database ToolsCellTracker


• A Nokia tool for collecting statistical information from NMS/2000:• Network performance• Traffic information

• Reports can be run for one- or many cells

• Menu-based user interface

• Runs in UNIX-environment

• Very useful for troubleshooting and network optimization

Database resolution is criticalfor accurate coverage prediction!


Digital Maps

Layers of one block

One pixel / unit


Digital Map Data

• Pixel (map unit) is the smallest detail of a digital map

• Pixels are squares, defining the resolution of data

• The value of a pixel is an average over the area covered

• Typical resolution 2m... 500m

• All layers of a block have the same resolution

• A map can contain blocks with different resolutions


Geographical Information Systems

• Computer system capable of assembling, storing, manipulating, and displaying geographically referenced information

• Layers of information

• Before the digital data can be analyzed, they may have to undergo other manipulations - projection conversions, for example - that integrate them into a GIS

• For further info: http://www.usgs.gov/network/science/earth/gis.html


Datum (1/2)• Geodetic datum (e.g. World Geodetic System 1984, WGS-84) defines

an ellipsoid to transform potato-shaped earth surface to a plane surface. Any rectangular coord. system can then be used on a plane surface.

• Coord. transformation Lat/Long -> rectangular system: a combination of the Ellipsoid used + coordinate system used on plane surface. Most common combination (e.g. in GPS) is WGS-84 ellipsoid + UTM rectangular coord. system.

• Flat-earth models • used for plane surveying

• Complex ellipsoidal models • used for international applications• describe the size, shape, orientation, gravity field, and angular

velocity of the earth.


Datum (2/2)• Referencing geodetic coordinates to the wrong datum can result in

position errors of hundreds of meters

• Different nations and agencies use different data

• The Global Positioning System is based on the World Geodetic System 1984 (WGS-84)

• Requires careful datum selection and careful conversion between coordinates in different data

• Complete datum conversion is based on seven parameter transformations

• translation parameters• three rotation parameters and • scale parameter


Earth Models

• Ellipsoidal earth models are required to• accurate range and bearing calculations over long distances• compute position and waypoint information (Loran-C, and GPS

navigation receivers).

• Reference ellipsoids are defined by major (equatorial radius) and minor (polar radius) semi-axes.

• Other reference ellipsoid parameters such as flattening, and eccentricity are computed from these two terms.

• The best of these models can represent the shape of the earth within about one-hundred meters.

• For further info: http://www.ispa.uni-vechta.de/staff/voser/mapref/mapref.html


Lat/Long Coordinate System

• Latitude, Longitude, and Height system• the most commonly used coordinate system • reference planes: Prime Meridian and the Equator


UTM Coordinate System

• Universal Transverse Mercator system• defines two-dimensional, horizontal positions.

• UTM zone numbers • designate 6 degree longitudinal strips • extending from 80 degrees South latitude to 84 degrees North latitude.

• UTM zone characters • designate 8 degree zones extending north and south from the equator.
