BTS Class

A BTS is a predefined business object of the class IltBTS that you can directly insert in a JViews TGO data source to represent graphically base transceiver stations in any of the graphic components connected to the data source. For a general introduction to predefined business classes, see Introducing business objects and data sources.

The IltBTS class does not define any specific attribute.

You can retrieve the class IltBTS using its GetIlpClass method. You can handle its instances as simple IlpObject instances and set and get its attributes with the generic methods getAttributeValue and setAttributeValue.

An IltBTS is made up of two types of object:

  • IltBTSAntenna objects, which represent cellular transmitting and receiving antennas.

The antennas and the item of electronic equipment constitute the detail objects of the IltBTS container object.

Antennas

An IltBTS object enables you to represent the antenna coverage of each cell in a cellular system. A cell corresponds to a limited geographic zone.

An antenna is an instance of the class IltBTSAntenna.

The IltBTSAntenna class defines the following attributes:

  • Power —Indicates the power of the antenna in watts

Name: power

Value class: java.lang.Integer

Attribute: IltBTSAntenna.PowerAttribute

  • Beam direction —Indicates the beam direction of the antenna in degrees

Name: beamDirection

Value class: java.lang.Integer

Attribute: IltBTSAntenna.BeamDirectionAttribute

  • Beam width —Indicates the beam width of the antenna, in degrees

Name: beamWidth

Value class: java.lang.integer

Attribute: IltBTSAntenna.BeamWidthAttribute

The graphic representation of an antenna includes:

  • An arrow line. The direction of the line corresponds to the beam direction and its length is proportional to the power of the antenna.

  • An arc. The span of the arc corresponds to the beam width and the radius of the arc is proportional to the power of the antenna.

Note

For a given power value, the length of the arrow line and the radius of the arc may differ. This is to allow for more flexibility in the graphic representation.

You can choose to display both the arrow line and the arc, or only one of them.

BTS equipment

A base transceiver station can be made up of an item of electronic equipment carrying the cellular antennas. An item of BTS equipment is an instance of an IltNetworkElement of type IltNetworkElement.Type. BTSEquipment. For details on network elements, see Network elements.
