PALO ALTO, Calif., Dec. 12, 2005 -- Agilent Technologies Inc. (NYSE: A) today announced the first release of signal creation capability for mobile WiMAX and WiBro applications. WiMAX is intended to make point-to-multipoint broadband network access widely available without the expense and distance limitations associated with wired options. WiBro is a broadband wireless Internet service for the Korean market, based on the 802.16e standard.

Agilent N7615A Signal Studio for 802.16 OFDMA software creates waveforms that comply with the WirelessMAN-OFDMA physical layer in the IEEE 802.16-2004, 802.16-2004/Cor1/D2 or D3, and 802.16e/D9 standards. Its ability to create downlink or uplink subframes in TDD or FDD makes it suitable for engineers testing base station and subscriber station equipment.

R&D engineers working in baseband receiver test and system verification will find that the N7615A software provides the flexibility to quickly and easily configure waveforms for both component and receiver design verification and testing. The software's intuitive graphical user interface grants engineers convenient access to the physical and basic MAC layer parameters, including bandwidth, cyclic prefix ratio (G), sampling factor (n), Fast Fourier Transform (FFT) size (512, 1024 or 2048) and frame length.

Using the software's frame setup parameters, engineers can generate high peak-to-average power ratio downlink or uplink signals to test transmission chain components, such as amplifiers. Generating signals for receiver test is simplified with automatic generation of correct FCH, DL-MAP and UL-MAP data.

"A crucial part of developing mobile WiMAX applications is the ability for manufacturers to thoroughly analyze RF characteristics," said Frank Palmer, product marketing manager with Agilent's Signal Sources Division. "Our new mobile WiMAX signal creation capability is a key component in ensuring manufacturers can quickly verify and test their component and receiver designs using correct waveforms."

The Agilent N7615A Signal Studio for 802.16 OFDMA can create up to 16 incrementally numbered frames per waveform and can configure frames for downlink, uplink or both. A flexible frame configuration provides for zone and burst allocations. Supported zone types include DL-PUSC, DL-FUSC, UL-PUSC and UL-OPUSC. The software can control signal generator functions remotely through the user interface.
