Next, the description of some tools and equipment involved in the experiments implementation:
LTE Downlink Channel Configuration
The T2010 and the UXM are conformance testing equipment in a single box which provide LTE connectivity using or not a core network. These components allow to configure the downlink channel, (EPC à Base Station à UE), to introduce impairments such as noise, interferences, and realistic scenarios: pedestrian model, vehicular model, etc.
The UXM is an evolution of T2010. It is used for LTE downlink channel configuration to test the UE performance in most of the possible potential scenarios.
LTE Uplink Channel Configuration
The Spirent Channel Emulator, used in the Experiment G to characterize the uplink channel, provides extremely realistic yet repeatable emulation of RF channel conditions. The emulator replicates real-world fading, spatial channel conditions, Additive White.Gaussian Noise (AWGN).
For SISO and MIMO systems which depend of the physical orientations of mobile devices, enabling motion scenarios.
Evolved Packet Core
The core network emulator of Polaris Networks consists of an implementation of the LTE basic core network, responsible for overall control of the UE within the LTE architecture.
Connection to external applications
Establishing the bearers etc..
Nokia Small Cells emulates the base station as access point to a communication network. Represents a hub in a wireless network and can be employed as a gateway between a wireless and a landline network.
USRP B210, this SDN platform is a board that provides coverage from 70MHz to 6GHz. The main scope of it is to implement Physical Layer libraries for LTE eNodeB deployment which emulates the Base Station using the OpenAirInterface open source. It enables programmatically efficient network configuration.
