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 PLANETAn 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 for BLER, BER can also be defined.

SINR threshold for BLER, BER cannot also be defined.

MIMO SM gain and TxDiv gain can be defined for each bearer

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 StatisticsATOLL 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 Interval Definition

Easily performed by specifying the START, END 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 HistogramUL CINR UL power control is

assumed so that the SINR is upper limited by the threshold for the highest MCS

No UL power control. SINR is based on max UE power

Monte Carlo Simulation and StatisticsATOLL 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

Monte Carlo Simulation

ATOLL PLANETMobiles not served (all dots) are intended to be everywhere

Mobiles not served (black dots only) are concentrated in weak coverage area

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
