1 Introduction Propagation model Tuning is a crucial procedure early in network Deployment as it enables accurate predictions of coverage and interference. The objective of this document is to describe the CW drive campaign and the propagation model tuning procedure for smartfren FDD 850 project in Jakarta of Indonesia. Here we do CW test and propagation model tuning base on FDD 850 MHz, and for LTE propagation model was calculated depend on tuned Standard Propagation Model. Anite Nemo Scanner and Coyote used to data process and Atoll (version : 3.2.1.7090) for model tuning Maps & Clutters 1.1

Model Tuning Process

The model tuning process including the following activities:        

Define models required to simulate coverage of different physical environments Site survey to find suitable sites for each environment Clearance Scanning Equipment and testing CW test and data collection Assessment and preparation data Model tuning for each environment Validate the model

1.2 Model Tuning Objectives

The propagation models included in this investigation refers to dense urban, urban, sub urban, and rural area. The following were used as objectives throughout the process: Mean error between -1 and 1 dB in global calculation each clutter Standard Deviation error
