4. Philadelphia CL01 Overview
DL throughput, % time on LTE, RRC Drops and Fail is derived from M2; UL throughput and Latency is derived from M4, Voice Drops and Voice Blocks is derived from M1
The above chart represents the current standing of the cluster. Signal overview, Bandwise distribution, PRB etc… are found in the following slides.

% RRC Connection Setup Failure = RRC Connection Failure/RRC Connection Attempt; % RRC Connection Drop = RRC Connection Drop/RRC Connection Successful
All HO failures does not lead to connection drop

20. Suggestions/market specific requests
Low hanging suggestions like sector swap, site down, top offender etc…. Or as per the request of your corresponding market.

21. Summary Most of the sites were not on Air
Average throughput for B41 is good
LTE coverage as well as throughput should increase as the new LTE sites come on air
Voice performance is good with only about .1% failure rate and no drop rate

23. Test Setup

24. Assumptions Drive Routes
Detailed routes built on top of T-Mobile baseline route expanded to cover majority of the roads especially in the Downtown, Urban areas & AGOOP worst performing meshes.
Test Configuration
Drive test configuration proposed in the following slides is based on:
Measure accessibility & retainability of Voice calls, this will also help us measure eCSFB performance
LTE Locked mode to provide performance on LTE & also compare LTE only mode vs. Global mode
Global Mode is to measure how end user will perceive the performance
Multi-streaming is done to squeeze the best performance of the network, it will identify problem areas where throughputs are low
Ping & Uploads case is there to measure latency and upload throughputs.
Scanner will provide RF footprint information for the sectors and will help in physical optimization efforts.
