Introduction This document is trying to compare the basic capabilities between Forsk Atoll 2.8.0 and Mentum Planet 5.0 for LTE planning. Only the single PC operation is considered. The comparison is on the following based on designing a small cluster using these tools • Network settings • MIMO handling • Perform coverage prediction studies • Perform Monte Carlo simulation

Bearer Link Adaptation Table ATOLL
PLANET
An SINR threshold is defined for each bearer, each mobility type, each mode (SISO, SIMO, MIMO TxDiv, MIMO SM) in DL and UL.
An SINR threshold is defined for each bearer, each mobility type, each mode (SISO, SIMO, MIMO TxDiv, MIMO SM) in DL and UL.
For each bearer, the SINR threshold SINR threshold for BLER, BER for BLER, BER can also be defined. cannot also be defined.
MIMO SM gain and TxDiv gain can be defined for each bearer

Scheduler for Monte Carlo Simulation ATOLL
PLANET
More options available: each column below has multiple options
Less Flexiable: 2 options only. Scheduler “none” only allocate minimum resource to each UE

Coverage Prediction and Statistics ATOLL
PLANET
Prediction Type
Can be defined individually. More options are available
Can be selected only from a list of pre-defined predictions
Define the Area for Prediction
The area is defined by a polygon, which can be drawn easily
The area can be the computer screen, or be defined by a grid file
Range and Easily performed by Interval specifying the START, END Definition and STEP SIZE
Each step level from start to end must be specified. More difficult to use.
Display Prediction
Can display coverage for each specified level
Display the coverage for entire range only
Statistics
Table or Histogram
Table or Histogram
UL CINR
UL power control is assumed No UL power control. SINR is so that the SINR is upper based on max UE power limited by the threshold for the highest MCS

Monte Carlo Simulation and Statistics ATOLL
PLANET
Define Area for Simulation
The area is defined by a polygon, which can be drawn easily
The area can be the computer screen, or be defined by a grid file
Statistics
More information available. Info for each individual mobile is available
Less information available. Info for individual mobile is not available
UL Loading and Noise Rise
More reasonable
Noise Rise is too low (<0.2 dB when average loading>60%)
Traffic Map
Easy to create
More effort needed for new users

Summary While a conclusion is required for comparison in general, we are trying to avoid it due to the limited tests on the 2 tools. However, in general it is believed that • Atoll 2.8.0 – – – –
•
Easy to use for new users Easy to create statistics MC simulation results are more reasonable Users have better understanding the tools due to the availability of all algorithms and formulas
Planet 5.0.0.230 – – – –
More difficult to use for new users More difficult to create statistics MC simulation results (UL noise rise) seems not reasonable The tool is harder to understood due to the unavailability of all algorithms and formulas
