Key Considerations

Project Settings

 On the General tab, if you want to save project display settings, associate a workspace (.wor) file with the Mentum Planet project.

 On the Geodata tab, specify the geodata settings respecting the required folder structure.

 On the Coordinate System tab, ensure that the units are defined appropriately and that you use units consistently across the project.  On the Folders tab, specify the Bin, Signal Strength, or Prediction View

folders on a central server if you want to save disk space locally.  On the Channels Models tab, specify the mobile speeds to be used

Key Considerations

Project Settings

 On the Prediction Heights tab, specify height parameters to be used in prediction generation. Enable the Used check box to display the defined height in the Active Height list

 On the Advanced Options tab, if you are using Data Manager, enable sharing permissions. When a file type is shared (i.e., the check box is enabled), the absolute path to the data is stored in Data Manager.

 On the Custom List tab, create pre-defined lists that you can use when adding custom attributes to project elements (such as a site, sector, or antenna) on the Custom Data tab.

 On the Custom Data tab, select the item for which you want to define a custom data definition. The parameters you define for custom data determines the requirements that dictate whether data entered is valid.



On the Network Perfomance Management tab,

performance platforms to retrieve sector load values. Then further visualize Key Performance Indicators(KPI) for a specific day or time.

Project Settings

Configuring a Mentum Planet Project

Mentum Planet fully supports User Mobility.

Mobile speed values are used when you define subscriber types in the Subscriber Settings dialog box. Each usage type is associated with a mobile speed. Channel models are also used when you define modulations in the Network Settings dialog box. The impact of the channel

model (i.e. of the mobile speed) is greater at higher

Using the Import Export Wizard – Checklist and Notes

1. Create/Use a template by exporting a dummy site to an excel file

2. Use the minimum number of worksheets for the initial import, i.e. Sites, Antennas, Sectors, Sector_Antennas, Sector_Antennas_Ports

3. Use the correct format for the data in the columns/cells, i.e. numeric vs text characters. The template will give you a hint. Be aware of limitations in number of characters

4. Use default values from the template for to fill in for data that you do not currently have.

5. If you wish to import flag data, create the flags and conditions in your project first or import the flags in excel format.

6. Test with a few sites if it works before importing the whole data. 7. See the log file for warnings or error messages.

8. When importing data with antenna data, make sure the antenna files exist in the project. If they are not in the project, mPlanet may substitute them with a default antenna.

Propagation Models

What is Model Tuning?

• Adapting the parameters of a

propagation algorithm to

improve propagation modeling

accuracy

– Measurements are used to perform such task

– Entirely automated using Planet model tuning

capabilities

– Operators can use different strategies on how to tune models

– Each model has its own unique parameters and hence, unique tuner

- Drive Test minus Prediction

+ Theoretically Ideal Model Tuned Model Un-tuned Model 0 dB P e rce nt age of D ri ve Tes t P oi nt s

Propagation Models

Classes of Models

• Empirical models

– Result from experimental measurements of path loss – Very fast, non tunable and of poor accuracy

• Slope-based models with diffraction algorithms

– Result from experimental measurements and mathematical modeling expressions

– Very fast, very tunable and of good accuracy – Require tuning and little re-use possible

• Deterministic models

– Result from development of propagation science – Slow, reasonably tunable and good accuracy – Highly re-usable

• Hybrid models

– They use several algorithms & techniques to achieve optimum accuracy – Highly accurate and tunable with reasonable performance

Propagation Models

Planet Models

• Planet General Model (PGM)

– A de-facto standard in the industry today

– Multi-variable slope based model with local adjustment and

hence, highly tunable

– Good macro-cellular accuracy, very fast and easy to use

– Requires tuning and hence, offers limited re-usability potential

– Ability to define whether clutter heights should be used for

inclination angles and/or for diffraction calculations

PRX= PTX + K1 + K2·log(d) + K3·log(Heff) + K4·Diffraction

+ K5·log(Heff)·log(d) + K6·Hmeff + KCLUTTER

Propagation Models

Planet Models (CRC Predict)

• CRC-Predict

– Deterministic model based on physical optics (Fresnel-Kirchhoff

theory), which is expressed in terms of the Huygens’ principle of optics

– Used when both detailed and accurate terrain and clutter data are

available (10 – 30m resolution)

– Good accuracy in macro-cellular environment

Propagation Models

Planet Models (CRC Predict continued)

CRC-Predict uses a marching algorithm

where the field values are calculated by the vector sum of all the free space and reflected pairs from each field point of the preceding series

Propagation Models

Planet Models (PUM)

Propagation Signatures

• Propagation Signatures represent the environment in

which propagation models are valid

• They can be created from sectors or from surveys

(where the transmitter configuration is the

information that is used, not the measurements)

Clutter Heights

Propagation Signature

Use of Propagation Signatures

• Propagation

Signatures can be

used for faster and

more accurate

propagation model

assignments

• Using sectors tuned in

the same market, or

tuned in another

market

Measurements Market A

Tuned & Signed Models

Model Assignments Markets A, B, etc.

Automatic Model Selection

Using the propagation model signature,

Mentum Planet validates the propagation model assignment by comparing the propagation

signature criteria with the sector parameters and recommending the best propagation model.

Automatic Model selection

Click Select and Mentum Planet will automatically compute scores for all

propagation models that have signatures in the project and show the best propagation model to be used.

Best propagation model for this sector is PGM_Dense Urban_2650_MHz

Automatic Model selection

The Automatic Model selection can also be done for a group of sites by using the Automatic Propagation Model Assignment tool.

Propagation Models

Tuning

“Everybody believes in drive testing, except the guy who drive tests.

Nobody believes in predictions, expect the guy who generates them.”

Propagation Models

Tuning (methodologies)

Tuning Planet Models using drive test data • Same methodology for tuning all models • Unified interface for survey

loading/filtering

• Advanced Filtering to best suit the needs of the data and area

• Powerful grid analysis tools to validate produced models

Survey Data

Importing and Filtering

You can modify survey data to remove anomalous points by:

 Averaging the data  Filtering the data

 Removing data from the Map window

Identifies valid surveys that have not been assigned to a sector. Identifies valid surveys that have been assigned to a sector.

Identifies surveys that have invalid parameters or no antenna information. By adding antenna information to surveys based on the sector properties, you can change an invalid survey to a valid one.

Survey Data

Mentum Planet offers a comprehensive set of features to handle survey

Generating

 Modeled−are calculated

using the propagation model assigned to the site or sector.

 Merged−are calculated

using unmasked survey data and path loss values

converted from signal strength readings.

Predictions

Generating (Drive Test/Prediction Merging)

• Different names have been given to this concept: survey prediction tool,

measurement-based predictions, path-loss tuning, etc

.

• All techniques relate to the same solution

– Use measurement data where it’s available

– Use predictions where measurement data is not available – Use interpolation of both in-between

• What you obtain in the end is a propagation prediction that is better than

both a regular prediction and measurement data

• Typical accuracy levels you can reach are

– 0 dB if you use the same data to generate and evaluate!

– Typically 3 to 5 dB RMS depending on the proportion of available drive test data in the area

Introduction

Defining a Data Manager Workflow

1 • From the Data Manager Administrator, obtain the necessary User ID and password.

2 • Connect to Data Manager and perform a Get to copy the project stored on the server to your local workstation.

3

• In Data Manager, lock the sites and settings you will be modifying. This avoids others submitting changes while you work on your area. To make this easier, create a filter by choosing View  Filter.

4

• Modify your local project as required. Ideally, you have been assigned a defined group or your area has been identified using specific flags or a specific site set.

5

• On a regular and fairly frequent basis, connect to Data Manager and choose Synchronize to copy any modifications to the master Data Manager project to your local workstation and, simultaneously, to submit any changes your have made locally to the Data Manager so they are available to other users.

6

• Once you are satisfied with your project, you can upload modifications you have made locally to the Data Manager by choosing Submit to Data Manager.
