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 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

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)
