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.
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.
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.
