The Radio entity describes the electronic properties of the signals output by a particular Sector on a Site. A Radio can be linked to Sector entities by one or more Connection entities.

Radio properties

Some properties of a Radio are restricted, in that they can only take on one of a set range of values. For example, the Channel property can only be set to one of the values listed in the Channel Range. This helps prevent Radios from taking on invalid property settings that cannot be implemented. These ranges are also used by the Parameter Optimization Module when it is choosing values for the various radio parameters.

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

• Channel. The channel used by this radio. This can only take one of the values from the Channel Range property.
• PA Power. The power amplifier setting for this radio. This can only take one of the values from the PA Power Range property.

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

• Channel Range. The set of possible channels available to this radio.
• Pa Power Range. The set of possible Pa Powers available to this radio.

Radios also have these additional properties:

• Active. A radio can be turned on or off by setting this property. Active radios generate signals and will be considered when computing statistics and so forth. Inactive radios do not generate any signals and will be left out of analysis.
• Color. This is the color assigned to this radio. This color can be used to represent radios on the map, when coloring the serving sector plot.
• Name. This is the name of the radio. All radio names must be unique, in that no two radios can have the same name.
• Flag Values. The set of Flags for this radio.
• Location. The physical location of the radio. The location of a radio is taken to be the location of the associated Site.
• Prediction. The prediction model to be used to generate signals from this radio.
• Site. This references the site that this radio is attached to.
