Measured for Success...
With LTE field trials and deployments ramping up and all the excitement about this new technology, one key question yet to be answered for most operators is - what does the user really experience? In other words what difference will the guys and girls on the street notice... and will they pay to notice that difference?
Apart from climbing the LTE mountain, back at base camp operators still have 2G/3G networks to run. So how can operators efficiently run their existing network, reduce OPEX and get ready for a whole new era of change that’s about to happen to mobile networks?
Here at AIRCOM a lot of time has been spent in answering these important questions with tried and tested products and solutions geared for real world use. Assessing and improving user experience while decreasing OPEX is seen as one of the keys to success. AIRCOM’s post-processing solution RANOPT offers a crucial part of the answer using drive test and trace measurement post processing.
In preparation for LTE, RANOPT V6.2 allows operators to assess the true user experience of the network and assess the quality of the current network. It offers ways to significantly improve business processes around day to day activities, with faster, efficient drill down capability, increasing engineers output and helping to ease the burden in resolving network issues.
Some of the enhanced features include:
· Indoor measurement support and analysis including route correction for maximising returns from in-building voice and data users. Allows way point and docking points for in building, train and tunnel quality assessments. Manual and automatic route correction allowing measurement spread and extrapolation. Femto cells (also called Home eNodeBs) will soon become a real option to increase coverage and capacity where it’s needed most to ensure off load of traffic from already congested networks as LTE is introduced. Some in building tests are done across all technologies but assessment of indoor coverage and throughput will become a more important facet of LTE to assess as the technology deployment ramps up.
- Map tile troubleshooting for rapid fire problem resolution, increasing operational efficiencies and saving you time in reducing churn. Delivers immediate summary of problem areas with map tiling guiding users to problems and immediate call drill down enabling faster fixing of issues. The faster troubleshooting can be done with both the existing network and new LTE deployments the better the network quality experienced by the user who potentially doesn’t really care which technology they get the service on.
· Trace Support (UETR and CTR) for in-depth network troubleshooting especially for Data assessment. Synchronisation with drive/walk test data enables better, faster troubleshooting especially for data calls. With a packet base system like LTE, assessment of eNodeB traces will become crucial input to trouble shoot, decipher and understand LTE system behavior
- Optimised workflow processes and display of views for reducing operational inefficiencies and saving time using scheduled Job/Tasks to increase productivity. This will allow engineers to cope with the engineering efforts involved with deploying a new technology by automating both new processes involved with LTE and day to day processes around the existing network
And that’s not all, RANOPT is currently being used as part of AIRCOM’s global consulting services delivery to assess and deliver LTE field trials and vendor evaluation projects that are presently ongoing. For more details on services covered, please see www.aircominternational.com/LTE
RANOPT LTE R&D capability is being developed and directly used as part of a field trial being done for a major Tier 1 operator, and close liaison with a number of the world’s leading hardware vendors is allowing LTE field experience and requirements to be directly fed back into the RANOPT solution to enhance and update the capability required to deliver these projects.
This R&D capability and hands on experience gained by both consulting and software engineers is being driven directly into the RANOPT solution which will encompass the planned future release of AIRCOM’s LTE enabled post-processing product.
Current capability on RANOPT for use on the projects broadly covers coverage assessments around RSRP, RSRQ, RSSI and CINR/SINR, QoS profile and user experience measurement analysis. Further using simulated application layer test equipment, measurements for assessment of multi layer ftp throughput, assessment of latency and analysis of CQI and mobility features such as intra, inter LTE and IRAT handover (LTE to 3G and 2G etc) amongst a number of other analysis criteria and reports have been developed to meet the needs of a typical field trial for a new technology. Confirmed roadmap on capability will be published closer to completion of these field trials and release of LTE enabled product for wider market use.
You can’t get more tried and tested than that!
