The high capacity solution enables the user to connect the Propsim F32 channel emulator with multiple base stations equipped with different radio access technologies. For example, the system can support a lab set-up consisting of 2 LTE cells, 3 UTRAN cells, 2 GERAN cells and radio channel profiles for each lab cell that are mapped from applicable field recorded live network cell from drive test data.
This capability allows the user to evaluate mobile device performance and assess best available radio access utilization in mobility conditions. It also enables the user to optimize the network infrastructure configuration and parameters with multi-layered network infrastructure.
VDT Toolset accurately replicates the real-world environment
VDT Toolset enables the user to verify Key Performance Indicators (e.g. download data rates, VoLTE call success rate and call drop rate) relevant to verifying the end-user experience of accessing different applications.
The testing is conducted under various mobility scenarios such as handover between radio access technologies and between multiple radio base station cells.
The automated capability allows the user to set up a single test campaign that covers every user scenario and provides results for all requested KPIs.
VDT Toolset offers the user the ability to test data intensive applications such as video or voice calls supported by VoLTE, SRVCC and CSFB technologies. The user is able to easily measure data download rate, call success rate and call drop rate under various mobility conditions such as urban city environments, highways, railways and road tunnels.
The user is also able to simultaneously evaluate the use data intensive applications and voice call performance,which can reveal significant performance gaps between various devices due to different processing capacity and design optimization.
VDT toolset creates a controlled laboratory environment that enables the user to cost-effectively perform interoperability testing of network infrastructure from multiple vendors using a ‘golden reference’ device.
VDT Toolset allows the user to benchmark high-end smart phones in regard how well they perform by measuring mobile data performance and call drop rates KPIs under various mobility scenarios such as in a handover between base station cells in a multi-RAT network.
