UMA PerformNetworks

PerformLTE tesbed follows a holistic approach combining different type of equipments, LTE radio access emulators equipments, Evolved Nodes B (eNBs), User Equipments (UEs) both commercial and engineered to provide measurements, and an Evolved Packet Core (EPC) emulation system. All these elements can be combined and experimentation can be performed in all the components of a LTE network. In general terms LTE connectivity is provided through three different solutions, each one with a focus on a different research aspect, moving between emulation and real-world environments, three main scenarios can be differentiated based on the radio access type:

  1. Scenario based on a LTE radio access emulator (traditionally use for conformance testing) which provides a full LTE end to end emulation, including channel emulation with different fading profiles and operation in all the standardized LTE bands, both FDD and TDD. 
  2. Scenario based on commercial off-the-shelf eNBs connected to a commercial EPC. This scenario provides configurations very close to the one provided by operators.
  3. Scenario based on commercial LTE networks, in which the testbed offers devices connected to commercial mobile networks. Devices are equipped with TestelDroid, a tool which enables the monitoring of radio information and IP traffic.
