Comparison of Atoll & Planet for LTEPlanning Version 1.0 Date 16.9.2009 Soc Classification level 1 © Nokia Siemens Networks Edited by Tao Wan Presentation / Author / Date Comments First version 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 Soc Classification level 2 © Nokia Siemens Networks Presentation / Author / Date .0 and Mentum Planet 5.Introduction This document is trying to compare the basic capabilities between Forsk Atoll 2.8.0 for LTE planning. Only the single PC operation is considered.
