Dyaptive Systems produces the industrys most advanced and scalable wireless subscriber simulation and test systems for CDMA, UMTS, HSPA and LTE technologies. Dyaptive's DMTS systems use patented software defined radio (SDR) techniques to generate realistic traffic patterns, subscriber call model behavior and emerging data applications in order to test the capacity, performance and reliability of 3G and 4G networks. Modern 3G and 4G Mobile networks are both dynamic and adaptive in nature with network intelligence moving out of the core and into the edge of the access networks. The test challenge now is to simulate subscriber behavior at both the RF and IP interfaces to ensure quality and performance objectives have been met. That challenge has been successfully met by Dyaptive Systems with systems deployed by virtually all leading Radio Access Network (RAN) manufactures and many of the worlds leading mobile network operators.
