What Can Be Done With Mtp-4?; The Powerful Mtp-4 Chassis With Its Flexible Interfaces - ASCOM TEMS SYMPHONY Brochure

WHAT CAN BE DONE WITH MTP-4?

MTP-4 allows different phones (and other mobile user de-
vices) to perform intrusive tests to assess the QoS of mobile
services. These are the same functionalities that run on the
existing TEMS Symphony platforms. Users can control and
monitor measurements via a graphical user interface (GUI)
running on a light tablet PC or a remote computer via a
wireless link.
Different types of QoS tests can be executed in all
types and generations of mobile radio technologies (GSM,
GPRS, EDGE, CDMA2000, EV-DO, WCDMA, HSPA, WiMAX, and
LTE). The system user can then analyze the collected mea-
surement results and engineering traces online or in time
shift mode on the GUI. These results and traces can also be
post-processed by TEMS™ Discovery, as well as other third-
party tools.
THE POWERFUL MTP-4 CHASSIS WITH ITS FLEXIBLE
INTERFACES
The core module in an MTP-4 chassis contains four separate
CPU modules equipped with Windows
provides more than enough processing power needed for
quality algorithms such as Perceptual Objective Listening
Quality Analysis (POLQA) and Perceptual Evaluation of Video
Quality (PEVQ). The system simulates the activities of typ-
ical wireless users by accessing the mobile broadband con-
nection, and by utilizing all types of services in 3G and 4G
networks, without any restrictions.
Depending on customer needs, different types of in-
terface modules can be plugged into the main chassis. This
makes the MTP-4 not only very flexible but also expandable
and adaptable for future types of interfaces and new types
of mobile devices. Everything else needed for precise and
professional measuring and testing – such as a GPS receiver,
dedicated communication module for wireless operation,
power supply with UPS functionality, and hardware dongle
– are included in the MTP-4 system.
The following interface modules (MIF) are available:
ƒ Phone MIF: module to control test phones via USB
interface, audio interface, SIM card slot, powering, and
power cycling of the phone
ƒ USB 12V MIF: module with two power-cycled USB
interfaces and one switched 12VDC output to connect
commercial USB modem and RF scanners
ƒ MiniCard MIF: module with Mobile Radio PCIe MiniCard
for Mobile Communication 2G/3G/4G, SIM card slot, and
two antennas for voice and data testing
chassis. This will allow configurations for benchmarking on
Embedded OS. This
®
multiple channels in parallel of, for example:
ƒ Speech call testing with MOS evaluation over a test
phone, and IP data testing via USB modems
ƒ Speech call testing with MOS over PCIe MiniCard, and IP
data tests via another PCIe MiniCard
ƒ Video telephony call testing with speech MOS and video
PEVQ MOS over test phones
