Having a unique experience on building and chief-architecting world-class link-level Simulators (in LTE and other wireless standards), and having actively participated in the 3GPP RAN1 and RAN4 working groups' LTE/LTE-A simulation campaigns (study/work items), we undertake the responsibility of building new LTE simulators, according to your needs and in your favorite computing language, or re-factoring your own Simulators no matter how complex they are. In addition we take the responsibility of architecting your complex LTE simulators, and developing them to meet any RAN1/RAN4 or LTE modem needs and expectations.
