Year 2014-15 Atlanta program statistics
- 900+ Macro Site RF Designs
- 900+ LTE Macro Site RF Optimizations
- 300+ UMTS Macro Site RF Optimizations
- 100+ Macro Site Cell Sites Rehomes, Frequency Retunes, & PSC Retunes
- 6500+ Hours RF & RAN Performance Consulting
[/mk_custom_list][vc_column_text]**Alarm, RSSI and VSWR monitored throughout the optimization cycle[/vc_column_text][mk_custom_list title=”Observations”]
- Cluster consist of 12 LTE sites
- Baseline LTE coverage was poor near the sites
- Poor Session Continuity observed
- Highway connectivity gaps observed
- Baseline Time On LTE observed under threshold
- High RSSI issue observed on majority of sites
- MIMO swap on 2 site
- Overshooting cells observed from 12 Miles
- Multiple failures and drops observed in the cluster due to loss of sync between
- UE and node B.
- Overshooting cells identified.
[/mk_custom_list][/vc_column][vc_column width=”1/2″][mk_custom_list title=”KPI Achieved”]
Year 2014- 15 statistics given below.
- Time on LTE – 99.5%
- DL throughput – 16.31 Mbps
- UL throughput – 8.41 Mbps
- CS Accessibility – 99.91%
- PS Accessibility – 98.93%
- PS Retainability – 98.89%
- CS Drop Rate – 0.23%
- Achieved Traffic Distribution 40:60 respectively between 1C and 2C LTE carriers.
- IRAT Trending < 1.5%
[/mk_custom_list][mk_custom_list title=”Process”]
- Implemented CSRF script in the Network to clear MIMO swaps
- Following tilt and Parameter Changes in the network recommended (Based on Eqpt tool)
[/mk_custom_list][mk_custom_list title=”Result”]
- CS/PS KPI’s are all Green from the Final Drive Data
- DL/UL Throughputs look good for a 10 MHz Carrier
- All the sectors are transmitting as per Azimuths
- PS Accessibility improved from 98.2% – 100%
- PS Retainability improved from 97.8% – 100%
- ATT coverage footprint was much better than competitor Verizon after optimization
- After optimization number of setup failure and call drop reduced significantly, hence the session continuity and access to the network improved
