- Buyers Guide
“Agilent has always brought essential solutions to market when customers need them the most,” said Ron Nersesian, vice president of Agilent’s Wireless Business Unit. “The 3GPP LTE standard is frequently updating. Consequently, Agilent’s TD-LTE R&D resources are in China to ensure the quick response that the local market needs. We have developed several first-to-market TD-LTE test products to ensure the success of TD-LTE deployment that must meet some aggressive time-to-market goals.”
Agilent will demonstrate the following TD-LTE test solutions at Mobile World Congress, Booth AV21, outside the exhibit hall hosted by TD-SCDMA Industry Alliance:
ο Agilent 3GPP LTE TDD Wireless Library (W1910/E8895) for Agilent SystemVue and Advanced Design System (ADS): Works directly with Agilent’s MXA Signal Analyzer to help wireless-systems designers and verification engineers speed development of the evolving LTE TDD designs. It is the world’s first fully coded bit error ratio (BER) solution for the time division duplex (TDD) version of 3GPP’s long-term evolution (LTE) standard using 2x2 and 4x4 multiple input/multiple output (MIMO) technology. The solution allows fully coded BER measurements of a device under test, including simulation of channel impairments for multipath fading. It complements Agilent’s same capability for the frequency division duplexing (FDD) version of LTE and is expected to accelerate the development of mobile devices and base stations for the China market. Also recently announced is an LTE Baseband Exploration Library (W1912) for Agilent SystemVue that offers baseband algorithmic source code models, in industry standard .m-file format, for deeper algorithm verification of LTE-TDD systems. Agilent 3GPP LTE TDD Wireless Library (W1910/E8895) is available now.
o The Agilent N7625B Signal Studio for LTE TDD is a powerful, PC-based software application for creating standards-based TD-LTE signals using Agilent’s N5182A/62A MXG and E4438C ESG vector signal generators, and N5106A PXB MIMO receiver tester. The Signal Studio solution supports the 3GPP LTE TDD September 08 standard, offers multichannel capability for PDSCH, PHICH, PCFICH, PBCH, PDCCH, PUSCH, PUCCH, and has the ability to transmit DL and UL signals. The software provides basic capabilities well suited for testing components used in base stations and mobile handsets, such as power amplifiers and filters, and advanced receiver test capabilities that support transport layer coding, 4x4 MIMO pre-coding and static fading. This extensive feature set makes Signal Studio for LTE TDD the best choice for eNB and UE test from the component to the system level. The Agilent Signal Studio (N7625B) is available to order today.
ο Agilent 89600 VSA software provides RF and baseband engineers with a comprehensive set of LTE TDD signal analysis tools, physical layer testing and troubleshooting of LTE transceivers and components. LTE TDD downlink (OFDMA), uplink (SC-FDMA) and MIMO analysis is a single option. The VSA software offers industry-leading performance with EVM of < -50 dB (hardware dependent) and bandwidths of 1.4 MHz to 20 MHz. Modulation formats included are BPSK, QPSK, 16 QAM 64 QAM, CAZAC, OSxPRBS, TDD DL/UL allocation (0-6) and special subframe length (0-8), and 2x2 MIMO. This VSA software can be used with more than 30 Agilent products, including spectrum and signal analyzers, oscilloscopes and logic analyzers to make LTE measurements anywhere in the block diagram -- from baseband to antenna, on digitized or analog signals. It supports 2x2 MIMO analysis in conjunction with Agilent’s EXA and MXA Signal Analyzers, VXI based VSA analyzer and several scopes. It also has connectivity with Agilent’s Advance Design System (ADS) TD-LTE wireless library. Agilent’s 89600 VSA software for LTE-TDD pre-release will be available in the second quarter of 2009, with commercial release in the fourth quarter of 2009.
China Mobile will use the TDD version of LTE that will be compatible with TD-SCDMA and the rest of the world’s LTE. LTE, or Long Term Evolution, is a fourth generation (4G) mobile broadband standard and is aimed to be the successor to the 3G technologies GSM.
Agilent’s demonstrations will show how these products provide powerful and scalable design and test platforms that support the TD-LTE Radio Access Network (RAN) eNode B stations, and User Equipment (UE) development lifecycle -- from early physical layer and protocol development to conformance test.
Agilent’s complete offering of test solutions for mobile communication can be seen here at 2009 Mobile World Congress, Hall 1, Stand D45, Feb. 16-19.
