1. Introduction

1.1. Purpose

WCELLS.mbx 1.0 is an advanced

MapBasic application that can be used as visualization tool for

presenting cells belonging to mobile telephony networks on the map, as

well as some accompanying information.

WCELLS.mbx 1.0 relies on Mapinfo

as the main software application (minimum version is Mapinfo 6.0).

The input information (list of cells

with geographical information, network parameters and 3G->3G

neighbors) are *.txt and *.xls formatted files.

The outputs are graphic objects in Mapinfo (regions in the shape of

cells/sectors, colored according to values of input information or accompanied by corresponding labels).

The main idea is to help mobile telephony personnel in decision making, by

presenting information in visual rather than tabular form. The main goal is portability (independence of the information source) and flexibility (easy

updating & customization).

The main graphic tables support UMTS, GSM, CDMA and LTE technologies, however, features of WCELLS v1.0 support UMTS technology only.

1.2. Intended users

This Map Basic application, WCELLS.mbx version 1.0, is intended to be used by personnel involved in mobile telephony, primarily:

a) Cell Planning RF Engineers, dealing with PSC and neighbor relations

planning (UMTS),

b) RF Optimization Engineers, dealing with presentation, analysis and troubleshooting of mobile networks,

c) all other personnel, involved in geographical distribution of the sites in

any mobile telephony network.

WCELLS.mbx is a handy visualization tool, “user-friendly”, easy-to-use

application, even for users not experienced in Mapinfo.

For an experienced user, WCELLS.mbx speeds up significantly decision making process related to most frequent daily activities of Mobile Telephony

Engineering.

WCELLS.mbx does not guaranty any Optimization result. Author denies any responsibility for any damage that users might have as the consequence of

decisions based upon usage of this tool.

WCELLS.mbx is not related to any particular vendor. Any similarity in

terminology with any particular manufacturer of mobile telephony equipment is coincidental and not intentional.

The author reserves the right to change this program anytime without

notice.

This program is subject to copyright laws and it is exclusive property of author of the program, all rights reserved. Any altering, reverse engineering

or similar activity would be treated illegal and is punishable by law.

WCELLS.mbx v1.0 4

1.3 Main data/graphic tables

The main table containing information of all cells (UMTS, GSM, CDMA, LTE) is “T00_WCELLS”.

Additional tables are derived from T00_WCELLS according to “Layers”

concept of Mapinfo. Different layers contain cells of different RAN Technologies and frequency ranges, for example for UMTS cells, 3 tables are

generated, T01_WCELLS, T02_WCELLS and T03_WCELLS, containing cells of three frequency ranges. This facilitates independent usage of individual

layers within Mapinfo / WCELLS. User can define frequency range of group of UMTS cells before importing cell data from a text file, by giving

appropriate value (1,2,3) to the field F34_UMTS_BANDNO.

The table T00_WCELLS contains data and graphic information. Graphic

information is hidden (invisible by Mapinfo Browser).

Insertion of new cells into WCELLS is described in Chapter 2.1.

Manual insertion of new records in Browser is not correct method of creation of new cells (lacking graphic information). Manual editing of some fields of

T00_WCELLS (Longitude, Latitude, Dir, Antenna_size, Ant_BW), although not recommended, is allowed and after redrawing of affected cell/group of

cells (Chapter 2.11) would lead to correct displaying.

Changing table structure (adding/removing/changing fields) of any of WCELLS tables is not allowed.

Manual editing can be used, for example, to set globally Ant_BW of all cells to desired constant value, using Mapinfo option Update Column. Before such

global editing, it is highly recommended to backup the table T00_WCELLS, in case of undesired results.

***

In the following sections, the term “field” will be applied in the context of

T00_WCELLS table if not designated otherwise.

A detailed description of T00_WCELLS structure is given in Appendix I.

1.4. Presentation of cells in Mapinfo, using WCELLS.mbx

The graphic presentation of a cell in WCELLS.mbx consists of a Mapinfo region in shape of circle (omni cell) or part of circle (sector cell), whose

center is located at the pair of coordinates (Longitude, Latitude), the orientation reflects the chosen Azimuth, width of a sector can correspond to

Horizontal Antenna Beam Width, and the size of a sector would be according to chosen antenna Size, on the map.

In WCELLS v1.0, a default (recommended) coloring scheme is applied.

The following rules of default color coding are applied to UMTS cells:

- BLUE = ACTIVE (ENABLED) cell

- GREY = HALTED (DISABLED) cell - YELLOW = highlighted cell – (having a chosen parameter value, e.g. PSC;

serving cell, when displaying neighbor relations, etc.)

- GREEN = neighbor of the selected cell - RED = neighbor of the selected cell with the same PSC value

1.5. Installation and Concept of Application Directory

The initial folder of WCELLS.mbx application is chosen by user during installation, and will be referred in the following text as “Application

Directory”.

It is recommended to choose a hard drive location with enough space.

It is compulsory to choose a location where the user has all read/write

rights, which is essential for WCELLS.mbx functionality.

This location cannot be changed afterwards (of course, a new installation is another option).

Installation consists of simple copying/pasting of the following 6 files from

installation folder into Application Directory:

WCELLS_v1.0.MBX

wcells01.dll DriveInfoApp.exe

SerialNumber.txt

Projects.TAB Projects.DAT

Apart from the above, user has to provide the existence of C:\TEMP folder

and read/write rights in that directory. The following 3 files have to be copied there:

SerialNumber.txt (from installation directory)

WCELLS_Licence.txt License file (user specific) DriveInfoApp.exe Reader of Hard Drive Identification

Page 10: WCells, User Guide v1.0 - RFOPT

WCELLS.mbx v1.0 8

1.6. Concept of PROJECTS

Users can have various mobile networks to deal with, WCELLS.mbx can

present and manipulate only one of them at a time. In order to keep all data in an organized way, a concept of Projects in introduced. WCELLS v1.0

supports one project only.

Project is a set of data belonging to one mobile network (eventually having

multiple technologies).

Every Project has a unique name and is located in a separate file folder, which we will refer to as “Project Directory”. Project Directory name is

combination of number (provided by WCELLS.mbx) and generic name (defined by user).

Example: for the first project to be created and a generic name “TEST”, the

folder name would be “01_TEST”.

Project Directory is located in Application Directory (provided automatically by WCELLS.mbx).

Project Directory has subfolders with strict names, given by WCELLS.mbx

and not to be changed by user. If changed, the functionality of

WCELLS.mbx would be reduced or completely nullified.

Names, location, field structure and contents of Mapinfo files created by WCELLS.mbx are not to be changed manually by user, unless explicitly

specified.

WCELLS.mbx v1.0 9

2. Quick start

STEP1: Creation of our first Project

The program WCELLS.mbx can be started: a) by Double-Clicking on it in Windows Explorer or b) from Mapinfo, applying the following sequence of

commands: Tools, Run MapBasic program, select and open WCELLS.mbx (similar: Ctrl-U).

A window “Creating a new Project” will pop up and user is instructed to provide a new generic name for a Project, e.g. “TEST” (WCELLS will add

number 01 to Project Directory name).

After creation of the first Project, a “Welcome message” will come up, and the user will be offered to accept the terms of usage. The user is normally

expected to click “I AGREE”, meaning that he/she accepts the agreement and is then allowed to continue.

As the result of this, a new Drop-down menu will become visible at the far

right of the Mapinfo menu structure. The menu name is “UMTS-Cells” Choosing this menu would result in Drop-down options described in the

chapters to come.

Page 12: WCells, User Guide v1.0 - RFOPT

WCELLS.mbx v1.0 10

Also, a Map window would become visible, it’s name changed to “WCELLS

v1.0 – TEST, corresponding to generic name of open project.

Two Button Pads would become visible: “General” and “UMTS”.

Figure 3. Mapinfo windows after starting WCELLS v6.0 for the first

time

Finally, “Message window” will show up, where all the activities will be accompanied by appropriate messages.

Page 13: WCells, User Guide v1.0 - RFOPT

WCELLS.mbx v1.0 11

2.1 Quick Start - Generation of cells Mapinfo objects from txt file information

STEP2: Creation of WCELLS graphic presentation of UMTS Cells

The next step in our Quick Start would be to generate new cells from *.txt

file.

We would need beforehand to provide *.txt file, according to required

format. The template of required TAB separated file can be found in Installation folder: \WCELLS_TXT_TEMPLATES\NewCells_UMTS.txt. For the

first time, you may just use this file for your first project.

Alternatively, simply open this file using Excel and fill up information for new cells below the first row that contains field names (1 row per cell).

For UMTS cells, field F01_RANTECH should be “UMTS”.

This and other compulsory fields to be filled up are: F01_RANTECH (radio access network technology, default = “UMTS”) F02_CELL, (cell name, i.e. sector name)

F03_SITE, (site name) F04_LON, (longitude)

F05_LAT, (latitude) F06_AZIMUTH, (azimuth) F13_ANT_BW_HOR (horizontal antenna bandwidth, default = 65)

F18_ANT_GSIZE (antenna size in Map window, unit = 100m, default = 5) F34_UMTS_BANDNO (band, i.e. carrier number, default = 1)

The remaining fields can be left as “unknown” or they can be filled up with

more useful information, if known.

Now, when *.txt file is ready, we can use the following menu option:

UMTS Cells -> Project Setup and Maintenance -> Import Cells from Text File

Page 14: WCells, User Guide v1.0 - RFOPT

WCELLS.mbx v1.0 12

From Dialog, chose “UMTS” radio button, “Only new”, “All per carrier field” and click OK, then chose your file (you can import the template file for

testing purposes, having 6 UMTS cells, 2 sites).

As the result, new cells should be created and program would create separate layers and tables, per technology, (UMTS, GSM, LTE, CDMA layers),

some of them would be empty.

Figure 4. Map window after importing 3 UMTS cells (1 site ) from

template file.

Page 15: WCells, User Guide v1.0 - RFOPT

WCELLS.mbx v1.0 13

TROUBLESHOOTING:

Usual issue is that the input text file is not according to required format.

Example 1:

meaning that field F34_UMTS_BANDNO should be “1”,”2”,”3”, the other

values are not accepted.

Page 16: WCells, User Guide v1.0 - RFOPT

WCELLS.mbx v1.0 14

2.2 Quick Start - Cell coloring according to operational state

STEP3: Import “operational state” from *.xls and see ENABLED and

DISABLED cells

First, we have to provide *.xls file with the required format. A template file can be found in installation directory\WCELLS_XLS_TEMPLATES\ INPUT01

PARAMETERS - UMTS.xls.

Conditions: TAB = “UtranCell” Cell field name = “UtranCell”

Operational state field name = “operationalState” Operational state allowed values: 1 (ENABLED)

0 (DISABLED)

Now, when *.xls file is ready, we can use the following menu option:

UMTS Cells -> Import -> UMTS: Import OperationalState from XLS File

Then, a file should be chosen and open. WCELLS will then update the field

F19_STATE with imported data. If we have chosen the template file, the result will be coloring 4 cells in blue (enabled) and 2 in grey (disabled) as

shown below (according to contents of template file).

Figure 5. UMTS Cell coloring according to operational state : blue

(enabled) and grey (disabled)

WCELLS.mbx v1.0 15

2.3 Quick Start - Cell Information after selection

STEP4: Select a cell and display Cell_Info_UMTS window

Cell selection is performed by mouse-clicking on the Mapinfo Selection

button and then mouse-clicking on a cell, e.g. UMTS cell. This causes

the appearance/change of “CELL_Info_UMTS” window, where some fields of

T00_WCELLS table are presented in text form and updated according to the chosen cell.

Figure 4. CELL Info window related to an UMTS cell

This window can be moved around by clicking the mouse on it and holding it while moving.

Most operations on cells are executed after cell selection.

Page 18: WCells, User Guide v1.0 - RFOPT

WCELLS.mbx v1.0 16

2.4 Quick Start - Cell Search

STEP5: Searching for a cell and centering Map window around it

For cell search, user should click on the button in UMTS Button pad.

User is offered a dialog window with two options.

Cell name can be selected from a ListBox (1) or can be edited in a TextBox (2).

The elements of ListBox are all existing UMTS

cells.

The result of this operation is that the Map Window will be centered around chosen UMTS

cell.

Figure 5. “Cell Search” dialog window.

WCELLS.mbx v1.0 17

2.5 Quick Start - Highlight of Neighbors (3G->3G)

STEP6: Import 3G->3G neighbors from *.xls and highlight the neighbors of

selected UMTS cell.

First, we have to provide *.xls file with the required format. A template file can be found in installation directory\WCELLS_XLS_TEMPLATES\ INPUT02

NEIGHBORS - UMTS-UMTS.xls.

Conditions: TAB = “UtranNeighbour” Count of Neighbors field name: “COUNT”

Cell field name = “CELL” Neighbors field names = “N1”, “N2”,…”N64”

When *.xls file is ready, we can use the following menu option:

UMTS Cells -> Import -> UMTS: Import UMTS->UMTS (3G->3G) NBRS from XLS File (1 row per cell, N nbrs)

Then, a file should be chosen and open. The successful import is ended with

the following message displayed in Message window: “===Import of 3G-> 3G NBRS ended ===

Next step is to select a UMTS cell and then click on button on “UMTS”

button pad. If we are working with the template file, the result will be coloring selected

cell in yellow and neighboring cells in green as shown below (according to contents of template file).

Figure 6. Highlighting 3G->3G neighbors of selected cell

Coloring back can be done using button from button pad “General”.

Page 20: WCells, User Guide v1.0 - RFOPT

WCELLS.mbx v1.0 18

2.6 Quick Start - Highlight of cells with given value of PSC (Primary Scrambling Code)

STEP7: Import primary scrambling code from *.xls and highlight UMTS with

chosen value of PSC.

First, we have to provide *.xls file with the required format. A template file can be found in installation directory\WCELLS_XLS_TEMPLATES\ INPUT01

PARAMETERS - UMTS.xls.

Conditions: TAB = “UtranCell”

Primary scrambling code field name: primaryScramblingCode

When *.xls file is ready, we can use the following menu option:

UMTS Cells -> Import -> UMTS: Import Scrambling Code (SC) from XLS File

Then, a file should be chosen and open. The successful import is ended with the following message displayed in Message window:

“===Import of SC ended ===

Next step is to click on button on “UMTS” button pad.

A window will be open and user can define a value of PSC (0-511). All cells on current Map window having chosen value of

PSC would be highlighted (colored yellow).

Message window will read the number of cells found with chosen value and their cell names.

Figure 7. Highlighting UMTS cells with chosen value of PSC

WCELLS.mbx v1.0 19

2.7 Quick Start - Changing cell size

This option is used to change size of all visible

UMTS cells in Map Window to a value chosen from the offered listbox (1,2,…,9,10,15,20).

(unit=100m, roughly).

This option is convenient when density of cells is much different in different areas (usually

smaller cell size is convenient for downtown areas).

Also, user can chose to change size of one

layer only (belonging to Carrier 1, 2 or 3).

2.8 Quick Start - Changing cell width

This option is used to to change sector bandwidth of all visible cells in Map window to a value chosen

from the offered listbox (20,30,…,80,90 degrees).

Also, user can chose to change BW of one layer only (belonging to Carrier 1, 2 or 3).

Figure 9. Set UMTS bandwidth dialog window

Here is an example of changing sector width from

65 to 40 degrees.

WCELLS.mbx v1.0 21

2.9 Quick Start - Importing/Updating of basic UMTS network parameters from *.xls files (PSC, operational state, 3G->3G neighbors, RNC)

Some of “import/update” features are already described in previous chapters

(import of PSC, operational state, 3G->3G neighbors).

For import of RNC information, xls file format should be as follows (same Template file):

Conditions: TAB = “UtranCell” Cell field name = “UtranCell”

RNC field name = “RNC”

Figure 12. Cell info UMTS after importing PSC and RNC

Page 24: WCells, User Guide v1.0 - RFOPT

WCELLS.mbx v1.0 22

2.10 Quick Start - Deleting of all cells (per Technology or all)

This option is used to delete all cells of certain RAN Technology (UMTS/ GSM/CDMA/LTE) from T00_WCELLS table. User is asked to confirm this

operation. Also, it is possible to delete all cells from T00_WCELLS (regardless of RAN Technology).

It is typically used before a new import of all cells is performed.

Page 25: WCells, User Guide v1.0 - RFOPT

WCELLS.mbx v1.0 23

2.11 Quick Start – Redrawing cells

User can redraw all cells in current Map window including coloring back to colors determined by operationalState, using the menu option

UMTS - > Redraw cells in window (size, color).

***

If user wants to color back all cells according to operationalState, another

option is to just click on the button: .

2.12 Quick Start – Toggling labels

User can toggle site labels clicking on .

Labels are initially set according to carrier 1 (table T01_WCELLS), next click

set labels to carrier 2 (table T02_WCELLS), the next one to carrier 3 (table T03_WCELLS).

Clicking on button remove all UMTS labels.
