R&S®AFQ-K264 ECMA-368 (MB-OFDM UWB)

Key Facts

The R&S®AFQ100B is the right choice for developing and testing UWB components and receivers in the baseband. Its system bandwidth of 528 MHz fits for one WiMedia band which can comfortably be generated with the R&S®WinIQSIM2 option R&S®AFQ-K264

Key Facts

Ultra-wideband is a radio technology that can be used at very low energy levels for short-range high-bandwidth communications. The FCC and ITU-R define UWB in terms of a signal for which the bandwidth exceeds the lesser of 500 MHz or 20% of the center frequency. One approach to this is WiMedia-UWB which uses a multiband OFDM technique (MB-OFDM). This new standard will for example be used as physical layer in the next Bluetooth generation and for wireless USB. The WiMedia specification divides the UWB frequency spectrum of 7.5 GHz (3.1 GHz to 10.6 GHz) into 14 bands of 528 MHz each. The information transmitted on each 528 MHz band is OFDM modulated (122 subcarriers). To achieve a MB-OFDM the bands are grouped together into 6 band groups. The OFDM packets are then spread using a Time-Frequency Code (TFC).

The R&S®AFQ100B is the right choice for developing and testing UWB components and receivers in the baseband. Its system bandwidth of 528 MHz fits for one WiMedia band which can comfortably be generated with the R&S®WinIQSIM2 option R&S®AFQK264 (only available for the R&S®AFQ100B).
