Method Detail

updateTxPowerChoices

protected List<Integer> updateTxPowerChoices(String band,
                                             String serialNumber,
                                             List<Integer> txPowerChoices)

Determine the new tx power choices based on user and allowed channels from deviceConfig.

Parameters:

band - the operational band

serialNumber - the device's serial number

txPowerChoices - the device's available tx powers

Returns:

the device's updated tx powers

computeTxPowerMap

public abstract Map<String,Map<String,Integer>> computeTxPowerMap()

Compute tx power assignments. This is the core method of this class.

Returns:

the map of devices (by serial number) to radio to tx power

updateDeviceApConfig

public void updateDeviceApConfig(DeviceDataManager deviceDataManager,
                                 ConfigManager configManager,
                                 Map<String,Map<String,Integer>> txPowerMap)

Program the given tx power map into the AP config.

Parameters:

deviceDataManager - the DeviceDataManager instance

configManager - the ConfigManager instance

txPowerMap - the map of devices (by serial number) to radio to tx power

getApsPerChannel

protected Map<String,Map<Integer,List<String>>> getApsPerChannel()

Get AP serial numbers per channel.

Returns:

map from band to channel to list of AP serial numbers
