Diversity OptimizerThe quality of experience optimizer
The integration of new technologies and services into mobile networks increases complexity and investments. Mobile operators have to continuously verify and optimize their services and the perceived quality of experience to assure customer satisfaction and to reduce churn. New services need to be tested and optimized which requires in-depth optimization measurements throughout the whole network lifecycle.
Diversity Optimizer is a powerful and flexible multi-technology RF and service quality (QoS) optimization tool for mobile operators and infrastructure vendors. It runs on standard laptop PCs for drive tests, and on tablet PCs for indoor and walk test-based measurements.
Diversity Optimizer supports more than 100 test devices, including the latest commercially available Android smartphones, USB modem data devices, SIP client, and RF scanners such as the Rohde & Schwarz R&S®TSME scanner. External devices can all be easily connected via standard PC interfaces, including USB, PCIe, and Ethernet. Running on a PC-based operating system, Diversity Optimizer can also be equipped with SwissQual QualiPoc Android smartphones, offering the portability and flexibility of a handheld tool with the power of a PC.
With its intuitive and easy-to-use interface and the possibility to connect up to six test devices as well as an RF scanner, Diversity Optimizer supports all possible optimization test scenarios. Diversity Optimizer is an ideal solu-tion for drive and walk test-based optimization campaigns.

Key Use CaseDrive testing for QoE optimizationTo maintain customer satisfaction, the quality of expe-rience (QoE) of end-to-end services, such as voice, data, video, and messaging, must be regularly verified. Diversity Optimizer can be used to measure a compre-hensive range of QoE key performance indicators (KPIs), which deliver information to initiate optimization tasks. Multiple network technologies can be tested in parallel, depending on the connected devices. With SwissQual’s flexible interface NQView, either standard or fully cus-tomized monitors can be used. In addition, audio alarms and information pop-up messages are available to ensure nothing important is missed during a measurement.
Fully automated, precise, and comprehensive radio fre-quency measurements can be collected simultaneously,
thanks to a connected RF scanner. Using indoor mapping functionalities, Diversity Optimizer can also be used for in-door optimization measurements and for troubleshooting tasks. For optimal portability and carry weight, the con-nected smartphone can be detached from the Optimizer and used as a standalone QualiPoc Android handheld tool.

Product HighlightsComprehensive solutionEmploying smart functionalities to solve specific prob-lems, Diversity Optimizer promotes cost-efficient work processes, minimizes human errors, and improves pro-ductivity. Mobile operators and testing service providers can use a single tool to address service quality and RF optimization troubleshooting at once.
Reflecting the real end-user perspectiveBy performing service testing directly on the end terminal,mobile operators and testing service providers can gain valuable insight into subscriber behavior, thus measuring the real user experience.
Systematic problem isolationSwissQual’s root cause analysis framework, together with POLQA testing, allows mobile operators and infrastructure vendors to troubleshoot the network, receiving useful insights of an issue’s possible cause, thus saving costs and gaining efficiency during analysis.
Universal software interfaceWith SwissQual’s proven and powerful Diversity software, Diversity Optimizer can be reliably used with all technologies, testing them with commercially available smartphones, USB modems as well as state-of-the-art RF scanners.

Key Product Features Full testing flexibility Diversity Optimizer provides great flexibility for any test configuration and software interface.
Hardware configurationı up to six external devices can be connected in parallel,
including the latest commercially available smartphones, USB modems, and GPS antennas as well as state-of-the-art RF scanners.ı optionally, tests can be conducted with SwissQual’s QualiPoc Android handheld, which can also be used as a standalone optimization tool.
Software interface NQViewı SwissQual’s NQView provides a powerful and flexible
single interface to configure, monitor, and replay measure-ments.ı the graphical user interface offers completely customiz- able monitors, acoustic alarms, and pop-ups for real-time testing as well as in replay mode.ı support of MapX® and OpenStreetMap mapping function- alities with the possibility to use an indoor layout picture as a base for indoor mapping.
Comprehensive service testing Diversity Optimizer offers comprehensive voice testing with POLQA, PESQ, and SQuad, using the advanced root cause analysis framework, to address possible causes of low quality of experience. Diversity is also an optimal so-lution to test other services such as data, messaging, and video (e.g. YouTube) with complete sets of KPIs included.
Using Diversity Optimizer will reward you with long-term values, including:ı SwissQual’s in-depth voice quality root cause analysis – including standard POLQA and service
performance KPIs for voice, data, and video ser-vices – to systematically isolate network quality
issues and propose precise actions to rapidly fix them. ı a future-proof product concept, supporting all
existing and future network technologies, results in lower total cost of ownership thanks to its flexibility to connect standard measurement devices.ı the continuous support of today’s and tomorrow’s
wireless network technologies and commercial devices while keeping total cost of ownership (TCO) down.
