GSM / GPRS / EDGE / UMTS (HSDPA) testing systems for network infrastructure.

Lab Test System LTS

GSM / GPRS / EDGE / UMTS (HSDPA)LTS is a family of testing systems for network infrastructure manufacturers and operators which tests the behaviour of infrastructure components (base transceiver stations and base station controllers) under load conditions. "Load" is the traffic and signalling information caused by the subscriber mobile stations that must be processed by the system infrastructure entities.

LTS generates load on the radio interface Um, allows the user to create load scenarios in a simple and system-atic manner and allows the user to evaluate the effect of the load on the infrastructure components in various traffic models. The system is fully automated and can incorporate interworking with network elements and other test equipment.

Air Interface Simulator


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.

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 AIS can also be used in combination with the LTS offering an automated environment comprehending both load and changing air interface charateristics to replay real world scenario's.
