For internal use only
Tool have two parts:
Only DL implemented in VBA version
Version from NPO Japan has also UL implemented, but it requires Matlab runtime evironment installation.
Can be used for LTE and HSPA.
Tool can be used to demonstrate the impact of radio conditions to cell capacity.
For internal use only
Tool has link budget related inputs that impact on capacity
Easy to link to any link budget tool.
Link level simulation results are used to estimate cell average capacity.
Default SINR vs. throughput tables are not the same as used in Dim tool!
For internal use only
For internal use only
Urban scenario
For internal use only
Dim tool provides spectral efficiency values for 100% load
Created with dynamic (Morse) simulator
Same propagation model used for different ISDs
No tilt or vertical antenna pattern considered
Capacity tool gives more options to study impact of area type and other radio parameters.
For internal use only
Summary
There is no correct value to average cell capacity, even in homogeneous grid used in dimensioning.
Changes in parameters defining RF configuration and environment can have bigger impact on capacity than specific capacity features (e.g MIMO)
It better to discuss about capacity trends and impacts of different parameters, than absolute values
For example, to highlight importance of clear cell dominance areas by showing impact of down tilt on cell capacity.
