NxClient


NxClient Key Features & Benefits (1/2)

Multi technology support: GPRS/EDGE, UMTS R99, HSDPA, HSUPA, HSPA+, LTE

Support for a wide range of commercial USB Modems Data Collection based on real time subscriber traffic Easy client installation with automatic registration (2 seconds) Client SW designed to minimize impact to end user: NxRay is a true

passive monitoring solution, no impact to normal usability of the modem & dashboard

Use the same services and applications as your subscribers Measurements done in areas where your subscribers are Minimum Log file size and deleted after successful upload NxClient Software updates NxRay caters for data integrity and privacy standard regulations: Hash

functionality avoids uploading and storing in NxServer sensitive data such as the subscriber’s IMSI (SMS adapts to customer needs)

Easy installation with automatic registration to support grand scale passive monitoring


NxClient Key Features & Benefits (2/2)

Support for Active Testing using a centralised web server approach Logging of most important network radio trace parameters Logging of key Layer 3 based events and KPIs having an impact on QoE IP based KPIs State of the art Web based reporting to view network QoE statistics Possibility to download reports locally in Excel, PDF, Power Point and Google Earth export for

geolocation if GPS is used LAC, BTS and Cell based KPIs geolocation: Map Stats Designed to work with high volume of clients: grand scale passive monitoring Possibility to perform queries on a simplified DB structure: NxMirror No HW Costs No Drive Test Costs Available both as perpetual license and as a service

easy installation with automatic registration to support grand scale passive monitoring


NxClient detailed description

NxClient relies on a patent filed software architecture, where there are two main components, the NxMonitor application and the NxFilter driver

NxFilter acts as a kernel level driver, between the dashboard and the device

This unique approach enables solving the problem with the modem/dashboard communication Dashboard has exclusive access to ports: our

architecture solves this issue Possibility to use the modem in Diagnostics mode to

collect QoE parameters/KPIs No impact to normal usability of the modem Limit the usage of RAM and CPU in end user’s

equipment

A unique patent pending design enabling true transparent monitoring

NxDroid


Why NxDroid?

Drive testing tools provide a technical measurement of specific routes, but don’t give insight about the smartphone end user perceived quality

Network probes or similar approaches collect high volume of traces but real time analysis on end user reported problems is usually complex

Need to obtain real coverage maps – as perceived by your subscribers

The above methods cannot locate end user experienced events that impact their QoE, such as a drop call, a PDP drop or a no coverage situation which would disable data connectivity

Android will own a 50% smartphone market share by 2012*

Fastest growing smartphone platform (rised from 3,5% to 25,5% share in one year, 3Q 2009 to 3Q 2010)

* Source: Gartner

..The PROBLEM of smartphone users


NxDroid end user application

Test your connectionPredefined and customizable active tests (Ping, FTP DL/UL,

HTTP Put/Get, Web Browsing). The active tests are uploaded to NxServer for analysis

Upload FeedbackEnables uploading end user’s feedback (Customizable)

Traffic StatisticsTo obtain traffic stats, such as traffic per process to

better control data consumption

Coverage CheckerEnables easy and quick coverage check and tests

geolocation


NxDroid Passive Key Features & Benefits (1/2)

Multi technology support: GPRS/EDGE, UMTS R99, HSDPA, LTE (from Android 2.3)

Support for the major part of commercially available Android based smartphones from Android OS 2.2 and onwards

Data Collection based on real time subscriber traffic and actual device

NxDroid client application can be downloaded from Google Play or distributed through a link (Marketing pages, support pages, mail, etc)

NxDroid client SW designed to minimize impact to end user: true passive monitoring solution

Use the same services and applications as your subscribers Measurements done in areas where your subscribers are


NxDroid Passive Key Features & Benefits (2/2)

Geolocation of QoE related events and Heatmaps support through NxWeb based maps

Logging of radio coverage information Logging of No Service areas Logging of Call events and statistics Logging of User Throughput Logging of processes traffic consumption Designed to work with high volume of clients No HW Costs No Drive Test Costs IMSI Hash option Centralised web server approach: NxWeb NxMirror enables Ad-hoc queries and custom reporting
