MVNOs and MVNEs as well as network operators themselves take advantage of LTS as a monitoring tool for the live network that detects and alarms about any performance degradations or outages. The LTS Mobile Network Monitor reports any inconsistencies immediately in form of an e-mail alarm or via SNMP traps. KPIs obtained by the system can also be queried at any time via SNMP, so that testers are permanently aware of the availability, reliability, quality, and integrity of the mobile network services from the subscribers’ point of view.

Wireless Communication Technology is finding its way into automotive industry – not only for entertainment purposes, but for security and safety reasons: With Car-to-X technology, drivers shall get information that other vehicles and road side facilities already have, for example, in case of a traffic jam ahead, a slippery road behind a curve or a necessary change of the traffic lane because of road constructions.

The Mobile Network Tester LTS is an automatic call generator, that establishes voice and data calls to and from actual mobile devices in the test system. Voice calls can be generated via the wireless PLMN network using actual mobile devices, via the PSTN network through analogue or ISDN lines or via Voice over IP. Wireless data sessions can be setup through the 3G or 4G network or over WiFi.

The main motivation for a subscriber to select a mobile network operator are the costs and the quality of the cellular network. Network coverage, reliability and performance are the key factors for customer satisfaction and influence many subscribers’ decision for service provider change. Qosmotec’s Mobile Network Tester LTS verifies the user experience of the mobile network for all relevant network applications and services and provides key performance indicators (KPIs) to assess the network quality.

QPER-C2X is a special adaptation of the signal strength emulator QPER, designed for mobile and Vehicular Ad-hoc Networks (MANet and VANet). Every radio devices in such an infrastructure-less network acts as a sender, receiver, and forwarder (router). Therefore, the ports of the QPER-C2X hardware are fully connected with each other by dynamically controllable attenuators. The system is fully designed for frequencies up to 6 GHz, since wireless communication for Intelligent Transport Systems (ITS) is based on the WLAN standard IEE 802.11p from 5.850 MHz to 5.925 MHz. The connected ITS stations can be either on-board units, as they are built into cars, or road side units that are used by road infrastructure (traffic lights, road work area delimiters, velocity signs). For tests in the lab, radio modules of such ITS stations are each kept in a shielding box that prevents any unwanted radiation over the air.

When many cars are equipped with 802.11p communication technology, high traffic density will also cause significant load on the radio channel. From normal wireless communication systems it is a known problem, that many users can cause a complete breakdown of the network. Car-to-X communication technology tries to protect itself against those kind of breakdown by a carrier sensing mechanism: Each communication device has to check first, if the radio channel is busy. In that case, it waits for a random delay to avoid packet collision on the radio channel, which causes a loss of both collided packets.

The QPER-C2X adaptation, that emulates signal strength between radio devices for Car-to-X communication in the lab, can be combined with the test automation software CANoe from Vector Informatik to enable a fully automated lab test under realistic radio conditions. This combination can be regarded as full test bench setups for Car-to-X test laboratories.

QPER Mobile Network Emulator enables engineers to simulate handover scenarios in mobile networks without a fully-fledged test lab. Based on Qosmotec’s QPER technology, it allows to test UE and SIM-Card behaviour in a completely emulated mobile network: Cells can be configured with all relevant cell parameters (MCC, MNC, LAC, CI, etc.), SIMs can be added to the HLR, and UEs can use standard circuit switched and packed switched services. Thus, the QPER Mobile Network Emulator emulates the all components of a mobile network – consisting of core and radio functionality – and creates RF signals. It supports GSM, GPRS and EDGE (900 MHz, 1800 MHz) as well as UMTS (2100 MHz).

The Qosmotec handover test system QPER is a versatile test platform for emulating the RF signal between radio devices in a wireless network, e.g., between mobile stations and radio infrastructure of a mobile network. It is employed in test beds where radio signals are transmitted through coaxial cables and specifically manipulated by testers. QPER can be based on various hardware platforms, from attenuator arrays to digital channel emulators.

The Mobile Network Tester LTS is able to treat the SIM card as a separate object under test. Also for international roaming tests, especially those specified by the International Roaming Expert Group (IREG), it is important to be able to put the focus of testing on the SIM card and to virtually (seemingly) place it into a mobile device in a potentially remote location.
