tatistic propagation model still prevail in wireless networking planning

and SPM is one of the typical statistic propagation model.2.6GHz propagation model calibration have been finished in the TD-LTE experiment city

and then 2.6GHz propagation trait in experiment have been learned.The difference of 2.6GHz SPM model between cities come to the conclusions and experiment.The conclusion and experiment have high reference in TD-LTE networking planning and optimization.The multi-frequency propagation model calibration will begin to work

the conclusions will help coordinate planning of the TD-LTE TD-SCDMA and GSM system.
