• Output the evaluation result of
802.16m technology
• ……
• Evaluate basic radio characteristics
(e.g., geometry distribution, large scale loss distribution)
• Output the evaluation result of LTE-Advanced technology
• Compare the results with other companies or Eval Groups
• Focus on the SCM channel before Apr ’09
• Check the accuracy of SLS
