•
EIRP [dBm]: This output data box provides the value of the Equivalent Isotropic Radiated
Power (EIRP) defined as the power of the transmitter plus antenna gain minus transmission
losses at User Terminal side. This parameter is automatically calculated by the tool.
•
Penetration / Body Loss [dB]: This input data box denotes the margin, depending on
User Terminal type, for absorption losses due to, for example, buildings, body, cars, etc.
Multiple Antenna Systems; this section allows defining if multiple antenna technology is
supported by a User Terminal, checking the corresponding check box Diversity/MIMO
Having
selected
Diversity/MIMO
(multiple-input
multiple-output)
option,
the
following
parameters need to be configured:
•
Number of Antenna Elements (Transmission/ Reception): These two input data
boxes denote the number (maximum 4) of transmission/receiver antennas with which
the Base Station is equipped.
•
Depending on the number of antennas, MRC, MIMO A and MIMO B options are
available:
o
MRC is the “Maximum Ratio Combining” technique feasible with at least two
receiver antennas.
o
MIMO matrix A technique adopts the “Space Time Block Codes” algorithm to
encode the data streams to enhance system coverage. It is feasible with at
least two transmitter antennas and one receiver antenna.
o
MIMO matrix B technique also known as “Spatial Multiplexing MIMO” is used
to enhance system capacity. It is feasible with at least two transmitter and
receiver antennas.
