The Sector entity represents a physical antenna attached to a Site. A Sector can be linked to Radio entities through one or more Connection entities.

Sector properties

Some properties of a Sector are restricted, in that they can only take on one of a set range of values. For example, the Azimuth property can only be set to one of the values listed in the Azimuth Range. This helps prevent sectors from taking on invalid property settings that cannot be implemented because of mounting constraints or similar. These ranges are also used by the Parameter Optimization Module when it is choosing values for the various sector parameters.

The following properties can only take values from the corresponding range property:

• Antenna Model. This is the antenna model that is attached to this antenna. This can only be set to one of the antenna models listed in the Antenna Model Range property.
• Azimuth. This is the direction in which the antenna points, as measured from North in a clockwise direction. This can only be set to one of the azimuth values listed in the Azimuth Range property.
• Downtilt. This is the physical downtilt that it applied to the antenna on this sector. This can only be set to one of the values listed in the Downtilt Range. Overture assumes that positive values of downtilt mean that the antenna is pointing towards the floor.
• Electrical Tilt. This is the amount of electrical downtilt applied to the antenna in this sector. This can only be set to one of the values listed in the Electrical Downtilt Range. Again, Overture assumes that positive values of electrical downtilt are take to mean that the antenna is pointing towards the floor.
• Height Above Ground. This is the height above ground level of the sector. This can only be set to one of the heights listed in the Height Above Ground Range. This is used as an input for various sector-based analyses, including the pathloss calculation. Note that sectors can have different heights to the site they are placed on. This can be used to model multiple mounting points on the same structure.

The ranges for the above can be accessed from the following properties:

• Antenna Model Range. This is the set of possible antenna models available to this sector.
• Azimuth Range. This is the set of possible azimuths available to the antenna on this sector.
• Downtilt Range. This is the set of possible downtilts available to the antenna on this sector.
• Electrical Downtilt Range. This is the set of possible electrical downtilts available to the antenna on this sector.
• Height Above Ground Range. This is the set of possible heights available to this sector.

Sectors also have these additional properties:

• Active. A sector is active if it is connected to at least one active radio.
• Color. This is the color assigned to this sector. This color can be used to represent sectors on the map, either as sector markers or when coloring the serving sector plot.
• EiRP. This is the effective isotropic radiated power for this sector summed across all contributing radios
• Name. This is the name of the sector. All sector names must be unique, in that no two sectors can have the same name.
• Flag Values. The set of Flags for this sector.
• Location. The physical location of the sector. This is used when drawing site markers on the map, and as an input for various sector-based analysis. A sector can be in a different location to the site it is attached to; this can be used to model antennas placed at the corners of buildings.
• Site. This references the site that this sector is attached to.
