For WCDMA/HSPA testing, Anritsu offered Protocol Test System (PTS) for R&D purpose. For LTE the basic tool is the RTD. The advantage of RTD as opposed to earlier generation PTS is that RTD is GUI based development environment that can speed up development and very little knowledge of test script development environment like TTCN-2 and TTCN-3 is required.
It may take few hours to get the hang of RTD, but once you understand how it works, you can start creating your own tests and scenarios at full speed. There are also example procedures available to get you started ;)
"The MD8430A is being used by LTE chipset manufacturers to ensure the quality of their products, speed time to market, and reduce design and production test costs." - Wade Hulon, Vice President and General Manager of Anritsu Company, Americas Sales Region.
You can learn more about MD8430A and RTD by following the links below:
Note: All the information mentioned in this post is my personal view and does not represent Anritsu's official views. Also if you manage to take few more minutes to create your own test then please do not blame me ;)

Not long back, I saw R&S demo of CMW-500 with the LG UE at the LTE World Summit. R&S has also verified ETSI 3GPP LTE TTCN-3 test cases with Qasara and has shown successful interoperability testing between Qasara’s Virtual UE and Rohde & Schwarz's 3GPP LTE Virtual Tester.
There is also a LTE TDD Technology Overview available to download from their website here.

The R&S CMW 500 is seen to be doing MIMO testing with LG UE. The throughput was reaching upto 60Mbps.
I also went to Ericsson Demo/Roadshow for LTE, HSPA and IMS Technologies. Unfortunately they didnt allow anyone to take any photographs.

Firstly, they released an LTE book just yesterday. The book will now be competing with four other very popular books on LTE already in the market. I managed to get an early preview of the book and I wasn't very impressed. There are nevertheless some sections which are very well written, containing unique information.
Secondly, Agilent are running some MIMO workshops and have released some very good presentations on MIMO on the web. You can download the material from the workshop here.
Finally, Agilent Technologies are to present three technical sessions at 2009 Informa LTE World Summit. Here is an extract from the press release:
Agilent Technologies has announced it will present three technical sessions and exhibit its LTE test application solutions at the fifth Informa LTE World Summit, Berlin, Germany, May 18-20. Agilent will exhibit its design-automation tools and flexible instrumentation for early LTE R&D design in components, base-station equipment and mobile devices.
The technical sessions are:
* MIMO Mia! -- What the Standards Didn't Tell You about MIMO;
* Honey, Who Shrunk My Mega Bits -- Practical Tips on Measuring Application Throughput in the Real World; and
* Doing Less with Moore - Challenges and Opportunities for Future Standards.
Agilent will exhibit its design-automation tools and flexible instrumentation for early LTE R&D design in components, base-station equipment and mobile devices.
The landscape is changing rapidly in mobile communications, combined with the challenges in global economies, yet LTE clearly is gaining momentum, said Benoit Neel, vice president and general manager of Agilent's Europe, Middle East and Africa field operations. Agilent remains fully committed to providing test solutions for the entire LTE development lifecycle -- from early RF and protocol development to conformance test and comprehensive, real-time network optimization and diagnostics.
Session highlights of Doing Less with Moore - Challenges and Opportunities for Future Standards, an LTE Summit workshop track on standardization presented by Moray Rumney, include:
* Examining trends in standardization
* Growing fragmentation and complexity, diminishing returns
* The growing gap between conformance testing and real life operation
* Opportunities for standards in an uncertain world
* Integration of macrocell and small cell technology
* Can femtocells do it all or do we need Wi-Fi
I am going to be there and am hoping to give youll detailed information on the event.

“We are thrilled and honored to have won a CTIA E-Tech award because it signifies the best and brightest technologies in the wireless market. We would like to thank everyone who participated in the voting and supported the MD8430A,” said Wade Hulon, Vice President and General Manager of Anritsu Company, Americas Sales Region. “The MD8430A is being used by LTE chipset manufacturers to ensure the quality of their products, speed time to market, and reduce design and production test costs.”
Approximately 300 entries were received for this year’s E-Tech Awards. They were reviewed by a panel of 30 recognized members of the media, industry analysts and executives who selected finalists based on innovation, functionality, technological importance, implementation and overall “wow” factor. More than 40,000 wireless professionals voted on the finalists to determine the winners in 18 categories.
The MD8430A is a highly accurate cost-effective solution for manufacturers of LTE chipsets and mobile devices to evaluate their products and improve time to market. Developed in conjunction with leading chipset manufacturers, the MD8430A augments Anritsu’s broad 3GPP test suite, providing developers of wireless devices and systems with a single-source test solution company.
The MD8430A is designed with 4 RF units that enable 2x2 MIMO system handover tests in a simulated network environment. The base station simulator can conduct end-to-end testing at downlink speeds up to 150 Mbps and uplink speeds up to 50 Mbps. All critical 3GPP air-interface LTE protocol tests, including baseband coding/decoding processing tests; protocol sequence tests, such as position registration, origination, termination, handover, terminal and network disconnect tests; and application tests, are supported. Powerful L1/L2 cache analysis functions are provided as well.

Continuing with the trends and keep the competition alive it’s now Aeroflex which launched the TM500 TD-LTE test mobile.
This latest LTE test mobile is designed to support Time Division Duplex for 3G LTE (TD-LTE) and will definitely compliment Aeroflex's TM500 LTE-FDD for 3G LTE Frequency Division Duplex quite well.
Ever since China mobile announced its plans for TD-LTE there was immense pressure on the equipment vendors to meet the demands. TM500 TD-LTE test mobile is designed to enable infrastructure equipment vendor’s match that demanding timescales for TD-LTE trials in China.
The TM500 TD-LTE's extensive Layer 1, Layer 2 and higher layer test features make it an indispensable testing peer that provides complete visibility even into the lowest layers of the radio modem by generating the detailed diagnostic data needed for engineers to verify the required functionality and optimize network operation and performance.
Following are further characteristics of TM500 TD-LTE:
- Support MIMO,
- Handover testing is simple and supported well,
- The test mobile can support 20MHz channel bandwidths and downlink data rates of upto 150Mbit/
All the above characteristics if the test mobile will enable comprehensive development and test support of base station and network infrastructure for the next generation of Chinese mobile technology.
The TM500 TD-LTE can co-exist in the same unit as the TM500 LTE-FDD protecting investment and maximizing test flexibility for engineers working on both standards.
Aeroflex will provide full in-country support for the TM500 TD-LTE so that technical questions and integration issues can be dealt with in Chinese and Aeroflex engineers can get on-site quickly, if needed, without having to fly in from Europe or the USA.
The TM500 TD-LTE will be available for customer shipment in late 2008.
It will be available both as a standalone unit and as an upgrade to existing TM500 LTE-FDD systems.
