Quality of Service Software Solutions
The Qosmotec concept embraces the entire range of network verification via test automation and unattended test execution. It enables network operators and infrastructure vendors to test their complex systems faster, more thoroughly and at lower expense. Qosmotec Software Solutions is the most flexible provider of standardized and customizable test systems for mobile communication networks.

	QPER	Reliable and repeatable radio performance tests require a controlled radio environment that can only be achieved in a laboratory setup. 3GPP [1] and WiMax Forum [2] have specified a set of channel models - corresponding models are being specified by 3GPP2 [3] as well - primarily dealing with multi-path fading. Investigating the impact of multipath is particularly important for antenna diversity systems (MIMO, SIMO) that are designed to counter just this effect.

	AIS	AIS is inserted into the coaxial links between real mobiles and base stations or base station simulators to simulate essential effects of signal propagation through open space, such as the free space path loss, slow or fast fading, drop-outs and various handover situations. The Qosmotec Air Interface Simulator (AIS) simulates aspects of the air interface which are of utmost importance for network or terminal validation in a laboratory environment, where radio signals must be conveyed in shielded coaxial cables. It can be applied to tests of network as well as terminal equipment.

	LTS	The purpose of LTS is to fully automate your lab tests, controlling commercial or test mobiles as well as supplementary test equipment, such as the Qosmotec AIS, protocol analysers or signalling generators, and even the network switches, in a synchronous test campaign. Test suites are stored in a database and can be replayed at any time. By controlling hundreds of mobiles, LTS can also be used as end-to-end load generator. Testing consumes about 40% of the software development lifecycle, and 80% of all tests are regression tests. Hence, automation of regression tests can achieve significant reductions of development costs and shorten time to market.
