Azimuth Systems Launches Global Beamforming Seminar Series
Experts in MIMO Channel Emulation Share Knowledge and Experience for Testing Beamforming Applications in
Acton, MA – May 17, 2010 – Azimuth Systems, Inc., a leading provider of wireless channel emulators, broadband
wireless test equipment and integrated solutions, today announced that the company will be presenting a series of
beamforming seminars to select companies in Asia, North America and Europe. These seminars will explain
beamforming, how it works, and the critical requirements that need to be met for accurate lab-based testing, as
well as provide examples of typical test cases and results. Beamforming is a key component of the time division
duplex (TDD) versions of 3GPP LTE (TD-LTE) and WiMAX 802.16e specifications. Forward-looking versions of these
specifications that include beamforming have been submitted to the International Telecommunication Union (ITU) for
approval as 4G IMT-Advanced radio interface standards. Beamforming has already been deployed in select WiMAX
networks around the world and China Mobile Communications Co. Ltd. is trialing TD-LTE and beamforming this year.
Beamforming is an adaptive antenna technique commonly used in TDD transmission to enhance system performance.
Beamforming systems perform channel estimations and then attempt to maximize signal to noise by changing the
directionality of the antenna array. When transmitting, a beamformer controls the phase and relative amplitude of
the signal at each transmitter, in order to create a pattern of constructive and destructive interference. When
receiving, antenna sensitivity can be increased for a better signal to noise ratio, especially when receiving weak
signals. Beamforming requirements have been specified in both LTE and WiMAX standards.
“We are eager to
share our beamforming test expertise and are excited to be presenting such a timely seminar to companies around
the globe as they promote the delivery of TD-LTE and WiMAX systems,” said George Reed, vice president of marketing
and product management at Azimuth Systems. “Azimuth’s award-winning ACE™ wireless channel emulators have been
successfully utilized in Multiple-Input, Multiple-Output (MIMO) beamforming tests during the past few years and
the ACE MX wireless channel emulator easily and readily supports the necessary MIMO configurations such as 4x4 or
8x2 required for beamforming testing for TD-LTE and WiMAX.”
The ACE MX wireless channel emulator is
architected to meet the demanding needs of MIMO and orthogonal frequency-division multiplexing (OFDM)-based
systems. The ACE MX MIMO channel emulator provides the advanced channel emulation features required for testing
WiMAX, LTE and other advanced wireless infrastructure equipment and devices, and includes all of the
backwards-compatible channel emulation features to test 2G/3G cellular products. The ACE MX wireless channel
emulator scales for testing single channel (SISO) up to 8X4 MIMO devices and also features bi-directional channel
modeling that can accurately emulate real world wireless over-the-air conditions in both the downlink and uplink
paths simultaneously – a mandatory requirement to test beamforming.
The Azimuth beamforming seminar series begins in China the week of May 17th and will continue in Europe the
week of June 7th. Additional seminars will be delivered to key LTE and WiMAX ecosystem companies in North America,
Japan, Korea and additional European countries over the next few months. For further information, please see
