Simulate real radio conditions such as mobility, path attenuation and fading effects – all in one solution

In the real world, subscribers experience very different radio conditions, mainly due to their mobility profiles with respect to the position of the eNodeB; PRISMA has specifically designed AirMosaic to take terminal mobility into account.

A realistic fixed distribution of subscribers within a cluster of cells can be simulated, but also tests can be created where the subscribers move programmatically, simulating mobile terminals while on a high-speed train or on a moving car. Closely integrated with UeSIM, AirMosaic can accurately simulate terminal mobility by interacting directly with the physical layer, signaling and uplink/downlink measurements on a per UE granularity.

LTE, UMTS and GSM radio interface testing with a typical smartphone application

Multi terminal simulations are of no use if traffic profiles do not mirror the real subscriber usage, and take into consideration the current fragmentation of smartphone operating systems, radio capabilities and terminal types (i.e. data-cards vs. handheld).  To address this issue, PRISMA has profiled several real smartphones currently available on the market and their “always connected” applications.
AirMosaic can rely on traffic models that reflect both a real customer base and real traffic that PRISMA’s solutions (UeSIM, 3GSIM and MsSIM) will simulate over the radio interface. A sample scenario could consider a customer base composed by different smartphones running different types of applications, voice calls and so on.
