WiMAX is intended to make
point-to-multipoint broadband network access widely available without
the expense and distance limitations associated with wired options.
Agilent Technologies has announced the first release of signal creation
capability for mobile WiMAX and WiBro applications. WiBro is a broadband
wireless Internet service for the Korean market, based on the 802.16e
standard.

“A crucial part of developing mobile WiMAX applications is the ability
for manufacturers to thoroughly analyse RF characteristics,” said
Shankar Roy Chowdhury, general manager - marketing, Agilent India. “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.”
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.
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. |
