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.
