3GPP LTE (Long Term Evolution) is a standard within the Third Generation Partnership Project to further evolve the UMTS mobile phonestandard to cope with future requirements. Moving to LTE includes increasing effi ciency, lowering costs, improving services, using new spectrum opportunities, and having a better in-tegration with other open standards. Standardi-zation for LTE is not yet complete. However, its completion in the near future will result in the new evolved release 8 of the UMTS standard.
The SORBAS 3GPP LTE Test UE is designed for testing evolving LTE mobile communications infrastructure and networks. It has the capa-bilities of a 3GPP LTE mobile terminal, with ad-ditional advanced test interfaces and features, making it an ideal tool for network infrastruc-ture equipment developers.

USE CASE 1: LAYER 1 / 2 TESTING & VERIFICATION
In this use case the SORBAS LTE Test-UE sim-ulates the complete behavior of a user equip-ment (UE) regarding PHY, MAC & RLC. With this setup, the eNB can be tested against a stand-ard-conform implementation of an LTE-UE. This allows the identifi cation of implementation faults at the very beginning of the development cycle.
USE CASE 2: ENB PROTOCOL EVALUATION
Testing the eNB only from the RF side is not suffi cient. The network interface must also be tested. In the past this has been an area ofprotocol testers and was a separate test case without any RF-testing.
With the advanced LTE standard, the eNBcomprises the former RNC (Radio Network Con-trol) functionality. Therefore, isolated network-protocol testing is no longer possible. SORBAS offers a clear and open interface to protocol test solutions from established vendors like Catapult, Ercom, Nethawk and Tektronix.
SORBAS a Modular & Flexible Platform
SORBAS can be confi gured to the needs of your test setup. The costomized solution of the SORBAS LTE test system can be as unique as
your test requirements. You can choose from many different options to (adapt - or customize) the system to your needs!

MEMBER OF THE LSTI
Signalion is an active member of the LTE/SAE Trial Initiative (LSTI) supporting activities with measurement and monitoring equipment. The LSTI was launched in May 2007 by leading telecommunications companies.
Signalion was the fi rst test & measurement supplier to join this group and contributes ac-tively to LTE fi eld trials.
STANDARD EVOLUTION
The 3GPP standardization is still ongoing. Some features of the future LTE system are not yet defi ned nor standardized. The main features of SORBAS are software defi ned. On this basis, the LTE Test UE can be quickly adapted to the ongoing standardization. Open features that are not yet standardized can be tentatively custom defi ned, e.g. on the basis of HSDPA/HSUPA, or they can be defi ned by Signalion based on our expertise.
The UE PHY implementation is compliant with FDD Mode according to 3GPP Release 8:
• TS 36.201 • TS 36.211 • TS 36.212 • TS 36.213
The UE MAC & RLC implementation is com-pliant with FDD Mode according to 3GPPRelease 8:
• TS 36.321 • TS 36.322

PROTOCOL API (APPLICATION PROGRAMMING INTERFACEThe API is open to customers and allows to integrate SORBAS into exiting protocolsimulators and –testers.The interface to the user plane offers • Confi guration based on service primitives and • direct IP input/outputThe interface control plane is based on service primitives (API to layer 3 implementation)
GRAPHICAL USER INTERFACEGraphical user interfaces (GUI) are provided for easy-to-use confi guration of the SORBAS System: • for L1/2 confi guration and control from a host PC connected via Ethernet. • to display/dump traces generated by the Test-UE such as: • BER (Bit Error Rate) • FER (Frame Error Rate) • CRC-checksum • CQI vector • AGC (Automated Gain Control) and many more. • Addition of customer defi ned traces are possible
MULTI-ANTENNA OPTION:Testing multi antenna technology not need to become a nightmare. Benefi t from Signalion’s long experience with MIMO-systems and from the fl exibility of the SORBAS hardware. Every single antenna SORBAS system can be upgraded to MIMO by simply adding RF branches and installing new software.
PROTOCOL TESTER INTERFACE OPTION:Layer 1 / 2 testing needs to be closely integrated with protocol tests as well as with network in-terface testing. SORBAS offers a defi ned and tested interface to well established cellular protocol test solutions.
BANDWIDTH OPTION: SUPPORTED LTE BANDWIDTHS:3GPP-LTE offer much fl exibility with different bandwidth options. So does SORBAS, choose from the supported bandwidths. Combinations of different bandwidth options are also available. Switching from one bandwidth to another one is just a matter of software.
