Market leading multi-

vendor post processing

for LTE

The LTE Rollout ChallengeThe mobile internet is here and many mobile networks are

experiencing a year on year doubling in the volumes of data traffic

they need to support. For most operators the only cost effective

strategy to cope with this exponential data growth is the deploymentof LTE (Long Term Evolution) networks.

LTE will enable operators to carry data traffic at a lower cost per bit

than current network technologies thanks to improved spectral

efficiency, a simpler all IP architecture, increased equipment

standardization and improved operational efficiency through SON.

However, LTE is a new and evolving standard and to realise its full

potential operators need to measure, validate and maximise real

world performance during the early phases of network rollout.

Drive testing will be a key feature of the LTE rollout process and

operators and vendors need a post processing tool able to support:

Acceptance Testing: A detailed acceptance process willenable operators and vendors to ensure the correct

performance of their LTE networks prior to launch. To

do this it is essential that they capture the right

performance measures, get the correct diagnoses for

problems and receive accurate guidance on how best to

resolve issues.

Planning Validation: Network planners need tounderstand if theoretical models used in planning tools

are accurate.

Functional Testing: During the early phases of rolloutbasic functional testing is required to ensure the network

is ready to handle traffic.

To complicate matters LTE provides unique features that will prese

new measurement challenges:

LTE features such as MIMO offer the possibility of higherdata rates but are not achievable in all network

conditions. The success of LTE rollouts will depend on

understanding when and where the new features are

available, being used and what improvements they

deliver.

LTE is first and foremost a data network. Voice measureslike drop call rate (DCR) are both easy to measure and

broadly representative of customer experience. Incontrast data networks require complex KPIs that

measure both the underlying IP network and the

services, such as web surfing, video streaming and

Twitter updates that run over it.

Inter technologyhandover is a traditional weakness innew networks technologies. Initial LTE deployments will

provide capacity overlays in data hotspots, meaning that

successful handover to 3G networks will be critical to

maintaining user experience.

Operators and vendors require a powerful and flexible post processi

tool that has been specifically built for LTE.

Actix Industry Leadership in LTEActix is maintaining its leadership in mobile network analytics and h

gained real world LTE experience in research projects, test networks

Analyzer for LTEActix has transformed its market leading Analyzer product to bring the

same advanced capabilities already used by 9 of the top 10 operators

in UMTS rollouts to LTE.

Analyzers power and flexibility enables it to support both detailed

radio engineering analysis and the creation of complex acceptance

KPIs and reports.

Support for LTE Logging Tools: Analyzer supports the latest logging

formats from all major vendors including Qualcomm, Accuver, Rohde

& Schwarz, Agilent and TEMs. Including both Ue and Scanner support.

LTE Network Measurement Visualization: Analyzer enables powerful

visualization of key LTE network measurements including:

Radio Quality CQI, RSRP, RSRQ Modulation & coding Frame usage MIMO analysis Scheduler variations. Resource allocation Event analysis: RRC, NAS

Flexible KPI Definition: Analyzers event and query engines allow

virtually any KPI to be built from LTE network and data service

measurements. The ability to define and measure a rich set of KPIs is

essential to acceptance reporting.

Dedicated Data Service KPIs: Analyzer provides top down KPIs that

measure the quality of how different data services delivered over LTE

are perceived by end users.

For each service thresholds can be set to define precise goals for data

service performance. These allow the detection of:

IP service setup failures and drops Data sessions failures due to radio link drops Low absolute throughput for a network technology Low composite throughput across different network

technologies (LTE, 3G, 2G)

Web browsing high page download duration High ping round trip time Lost pings

Data Session Analysis: Analyzer enables drill down to full data session

analysis providing in one location all the information required to

understand the root cause of the problems affecting the quality of

data services.

The analysis covers the entire data session and provides a view of data

service performance synchronized with network measurements and

the underlying layer three messages.

Detailed RF Analysis: Radio Network Analysis enables the analysis a

verification of RF conditions including coverage (overshooting, cross

feeders), interference, and neighbors.

IP Packet Inspection: Analyzer provides full IP layer decodes and

session analysis to provide full inspection into the IP traffic layer

supported by LTE allowing KPIs to be built that cover Jitter and other

measure of IP performance.

Summary Dashboard: Analyzer highlights failed KPIs and summarize

the performance of all data sessions in an easy to use dashboard.

From here engineers can quickly understand the performance of

individual data sessions, whether LTE features were used and drill

down to establish the underlying causes of any problems and areas o

poor performance.

LTE Acceptance Reporting: Out of the box reports can be tailored to

communicate whether a broad range of LTE acceptance criteria are

being met; these include:

Accessibility Retainability RF Verification (such as RSRQ, RSRP, CQI, MIMO, ) Service Verification (such as throughput, initialization

time, jitter, etc.)

Reports can use exclusion zones and other exceptions to paint an

accurate picture of network quality.

Benchmark reports can be built allowing operators to compare their

LTE network performance and coverage with their competitors and

their existing network.
