LTE eNode B Testing

The eNode B is the most complex part of the LTE access network, and is more complex than a UMTS Node B or GSM base transceiver station (BTS), since it operates without a central controller (RNC – radio network controller or BSC – base station controller). The functions of the central controller are performed by the eNode B itself, making it a critical component of the new LTE network architecture, and a critical consideration for testing.

Ixia provides the physical network interfaces that emulate all of the components that surround an eNode B in a live network:

User equipment connecting through Uu radio interfaces.
Other eNode Bs to model mobility situations, using the X2 interface.
Serving gateways over the S1-U interface.
Mobility management entities over the S1-MME interface.

Ixia's UE emulation includes:

Multi-UE emulation. Hundreds of users per sector, with 6-sector support, test any eNode B at its maximum capacity and complexity. With 2x2 MIMO, up to 125 Mbps of download traffic can be generated and verified.
Full Uu interface support and associated protocols: PHY, MAC, RLC, PDCP, RRD and NAS through available encoders and decoders, state machines and procedure libraries.
Uu simulation includes support for 5, 10 and 20 MHz channels, 2x2 MIMO, in-cable CPRI v3.0/4.0, and RF over LTE frequency bands I-XIV.
Simulation of real-world scenarios including register and de-register, handover including inter-eNode B, intra-eNode B and IRAT as well as interoperability with UTRAN, GERAN, CDMA2000 and IMS.

Our SSX devices allow operators to manage the growing capacity challenges of today’s 3G networks, while ensuring a smooth transition to the rigorous 4G/LTE environment. Handling GTP at scale is not only necessary for key 3G core elements, but for new data offload applications as well, and GTP will remain integral to LTE deployments. Ixia has been a good partner for Stoke, working jointly to push the performance envelope of mobile network test equipment. Ixia’s IxNetwork test solution enables us to validate our ability to reliably process GTP for mobile data offload deployments today, while paving the way for expanding the SSX’s role in LTE’s evolved packet core tomorrow.
