The following data are just sampled cases of various equipments that serve for Fixed Microwave radio systems, GPS, Cellular phones, Broadcasting, Mobile broadcasting, Fixed-satellite service, Wireless access, respectively.

The mission of this Task Force is to perform the demonstration test and submit the data to the upper level council for the discussion of the acceptable UWB interference level. Therefore, the Task Group does not make any evaluation on UWB interference acceptance level.

GPS Area Networks (WPANs)

GPS signal power is set to -130dBm.

In the left figure, the power level is as is, in both DS and MB, due to

too small output to set -75dBm/MHz (FCC Mask).

The right figure is set to -75dBm/MHz by removing IR BPF. The

X-axis value is from -75dBm/MHz. For example, 45dB means

-(75 + 45) = - 120dBm/MHz equivalent.

Y. Sanada (UWB Demonstration Experiments Task Force)


Cellular Phones Area Networks (WPANs)

  • Power measurements

  • The cellular receiver frequencies are located at the out of band of DS-UWB and MB-OFDM. Therefore, these powers are not measured and it means their power at that frequency is under the SA measurement limit of

  • -153dBm/Hz.

    • Interference Power at each desired signal strength point

  • Next Table shows the comparison between AWGN and UWB at each desired signal strength points. The “path-loss” in Table means the total loss from Tx terminal to Rx terminal. The values shown are calculated from ATT set, system loss and receiver internal loss. Also “Signal group A” means the grouped data, where the power measurement was not done due to SA limit. The most outstanding “path-loss” is listed from the data of the group.

    These results are obtained under the condition of the specific single UWB signal sources.

    Therefore it can NOT be said that the results obtained here are applicable to other UWB signals and/or its operation under the different conditions from specified here.

    • Because the influence of the UWB signal sources is different from that of the white noise, additional experiments are required in order to obtain the detailed results. The additional experiments should be conducted with the following conditions;

    • Different combinations of the system parameters

      (modulation schemes, FEC parameters, etc. )

    • Different signal levels

    • Receivers from different manufactures

    • With multiple UWB signal sources

    • Different frequencies offsets between UWB signals and FSS (as the UWB signal sources have ripples on their frequency spectrum)

    • More realistic transmission environments

    • As the bandwidth of the LNA is 575MHz, the FSS should be considered as a wideband system.
