Notes
-----
self.fGHz is an array, it means that Coverage is calculated at once
for a whole set of frequencies. In practice, it would be the center
frequency of a given standard channel.
This function is calling `loss.Losst` which calculates Losses along a
straight path.
In a future implementation we will
abstract the EM solver in order to make use of other calculation
approaches as a full or partial Ray Tracing.
The following members variables are evaluated :
+ freespace Loss @ fGHz PL() PathLoss (shoud be rename FS as free space) $
+ prdbmo : Received power in dBm .. math:`P_{rdBm} =P_{tdBm} - L_{odB}`
+ prdbmp : Received power in dBm .. math:`P_{rdBm} =P_{tdBm} - L_{pdB}`
+ snro : SNR polar o (H)
+ snrp : SNR polar p (H)

Notes
-----
self.fGHz is an array, it means that Coverage is calculated at once
for a whole set of frequencies. In practice, it would be the center
frequency of a given standard channel.
This function is calling `loss.Losst` which calculates Losses along a
straight path.
In a future implementation we will
abstract the EM solver in order to make use of other calculation
approaches as a full or partial Ray Tracing.
The following members variables are evaluated :
+ freespace Loss @ fGHz PL() PathLoss (shoud be rename FS as free space) $
+ prdbmo : Received power in dBm .. math:`P_{rdBm} =P_{tdBm} - L_{odB}`
+ prdbmp : Received power in dBm .. math:`P_{rdBm} =P_{tdBm} - L_{pdB}`
+ snro : SNR polar o (H)
+ snrp : SNR polar p (H)

Notes
-----
self.fGHz is an array, it means that Coverage is calculated at once
for a whole set of frequencies. In practice, it would be the center
frequency of a given standard channel.
This function is calling `loss.Losst` which calculates Losses along a
straight path.
In a future implementation we will
abstract the EM solver in order to make use of other calculation
approaches as a full or partial Ray Tracing.
The following members variables are evaluated :
+ freespace Loss @ fGHz PL() PathLoss (shoud be rename FS as free space) $
+ prdbmo : Received power in dBm .. math:`P_{rdBm} =P_{tdBm} - L_{odB}`
+ prdbmp : Received power in dBm .. math:`P_{rdBm} =P_{tdBm} - L_{pdB}`
+ snro : SNR polar o (H)
+ snrp : SNR polar p (H)
