1 GENERAL STRUCTURE

The first row of the file contains the keywords that define the order of the parameters in the following lines. Keywords are separated with semicolon or tabulator character.

Other rows in the file contain the cell definitions. Each line describes one cell and contains a set of parameters describing the cell as well as the site in which the cell resides. For both site and cell information, there are both mandatory parameters and optional parameters. Site and cell parameters are separated with semicolon or tabulator character.

The file format supports three data types: integer, float and string. Integer type is defined as a numeric value without dot character. Float type is defined as a numeric value with dot character. String type is defined as a set of any printable ASCII characters except semicolon.

2 PARAMETERS

2.1 MANDATORY CELL PARAMETERS

Parameter Keyword Type Description

System SYSTEM String AMPS, GSM, TDMA, CDMA, UMTS, TETRA, TD-SCDMA, WIMAX, EVDO or LTE.

Site Name SITE String Name of the site.

Cell Name CELL String Name of the cell.

Latitude LAT Float Latitude of the site in degrees.

Longitude LON Float Longitude of the site in degrees.

Decimal degrees (DD) express latitude and longitude geographic coordinates as decimal fractions and are used in many Geographic Information Systems (GIS), web mapping applications such as Google Maps, and GPS devices. Decimal degrees are an alternative to using degrees, minutes, and seconds (DMS). As with latitude and longitude, the values are bounded by ±90° and ±180° each.

Positive latitudes are north of the equator, negative latitudes are south of the equator. Positive longitudes are east of Prime Meridian, negative longitudes are west of the Prime Meridian. Latitude and longitude are usually expressed in that sequence, latitude before longitude.
