1. Introduction1.1. PurposeWCELLS.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 usersThis 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.

1.3 Main data/graphic tablesThe 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.mbxThe 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 - GREY - YELLOW - GREEN - RED = ACTIVE (ENABLED) cell = HALTED (DISABLED) cell = highlighted cell (having a chosen parameter value, e.g. PSC; serving cell, when displaying neighbor relations, etc.) = neighbor of the selected cell = neighbor of the selected cell with the same PSC value

1.5. Installation and Concept of Application DirectoryThe 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:
