    Description

    The bluetoothPathLossConfig object specifies parameters for the bluetoothPathLoss function. Use the bluetoothPathLoss function to estimate the path loss between Bluetooth® basic rate/enhanced data rate (BR/EDR) or low energy (LE) devices.

    Creation

    Syntax

    cfgPathLoss = bluetoothPathLossConfig
    cfgPathLoss = bluetoothPathLossConfig(Name=Value)

    Description

    cfgPathLoss = bluetoothPathLossConfig creates a default Bluetooth BR/EDR or LE path loss estimation configuration object.

    cfgPathLoss = bluetoothPathLossConfig(Name=Value) sets properties by using one or more name-value arguments. For example, Environment="Home" sets the signal propagation environment to home.

    Signal propagation environment, specified as "Home", "Industrial", "Office", or "Outdoor".

    Data Types: char | string

    Transmitter antenna gain, specified as a scalar or a row vector of values in the range [–10, 10]. Units are in dBi.

    Data Types: double

    Receiver antenna gain, specified as a scalar or a row vector of values in the range [–10, 10]. Units are in dBi.

    Data Types: double

    Transmitter cable loss, specified as a nonnegative scalar or a row vector. Units are in dB.

    Data Types: double

    Receiver cable loss, specified as a nonnegative scalar or a row vector. Units are in dB.

    Data Types: double

    Transmitter antenna height, specified as a positive scalar or a row vector. Units are in meters.

    Dependencies

    To enable this property, set the Environment property to "Outdoor".

    Data Types: double

    Receiver antenna height, specified as a positive scalar or a row vector. Units are in meters.

    Dependencies

    To enable this property, set the Environment property to "Outdoor".

    Data Types: double

    Path loss exponent of the specified environment, specified as a positive scalar.

    Dependencies

    To enable this property, set the Environment property to "Industrial".

    Data Types: double

    Standard deviation, specified as a nonnegative scalar. Units are in dB.

    Dependencies

    To enable this property, set the Environment property to "Industrial" or "Outdoor".

    Data Types: double

    Random number source, specified as "Global stream" or "mt19937ar with seed".

    • "Global stream" — The object generates a normally distributed random number by using the current global random number stream.

    • "mt19937ar with seed" — The object generates a normally distributed random number by using the mt19937ar algorithm.

    Data Types: char | string

    Initial seed for mt19937ar, specified as a nonnegative scalar.

    Dependencies

    To enable this property, set the RandomStream property to "mt19937ar with seed".

    Data Types: double

    This property is read-only.

    Path loss model of the specified environment, returned as 'TwoRayGroundReflection', 'LogNormalShadowing', or 'NISTPAP02Task6'.

    • If you set the Environment property to "Outdoor", this property returns the 'TwoRayGroundReflection' value.

    • If you set the Environment property to "Industrial", this property returns the 'LogNormalShadowing' value.

    • If you set the Environment property to "Home" or "Office", this property returns the 'NISTPAP02Task6' value.

    Data Types: char

    Create a default Bluetooth path loss estimation configuration object. By default, the object specifies an outdoor environment.

    cfgPathLossOutdoor = bluetoothPathLossConfig;

    Specify the transmitter and receiver antenna heights, in meters.

    cfgPathLossOutdoor.TransmitterAntennaHeight = 2;
cfgPathLossOutdoor.ReceiverAntennaHeight = 3;

    Specify the standard deviation, in dB.

    cfgPathLossOutdoor.StandardDeviation = 1.6667
    cfgPathLossOutdoor = 
  bluetoothPathLossConfig with properties:

                 Environment: 'Outdoor'
      TransmitterAntennaGain: 0
         ReceiverAntennaGain: 0
        TransmitterCableLoss: 0
           ReceiverCableLoss: 0
    TransmitterAntennaHeight: 2
       ReceiverAntennaHeight: 3
           StandardDeviation: 1.6667
                RandomStream: 'Global stream'

   Read-only properties:
               PathLossModel: 'TwoRayGroundReflection'

    Create a Bluetooth path loss estimation configuration object for an industrial environment, specifying the path loss exponent as 2 and standard deviation as 0 dB. A path loss exponent value of 2 and a standard deviation of 0 dB signifies that the Bluetooth signal propagates in free space.

    cfgPathLossIndustrial = bluetoothPathLossConfig(Environment="Industrial", ...
    PathLossExponent=2,StandardDeviation=0)
    cfgPathLossIndustrial = 
  bluetoothPathLossConfig with properties:

               Environment: 'Industrial'
    TransmitterAntennaGain: 0
       ReceiverAntennaGain: 0
      TransmitterCableLoss: 0
         ReceiverCableLoss: 0
          PathLossExponent: 2
         StandardDeviation: 0
              RandomStream: 'Global stream'

   Read-only properties:
             PathLossModel: 'LogNormalShadowing'
