The spatial distribution of the signal may be controlled by the directivity of the antenna used. Possible examples include: switching, re-orientation, phased arrays. |
40302b05ed4b2215fa8843099dfaf1df | 102 754 | 6.7 Combinations | In order to achieve the protection criteria and maintain an operational link with peer devices it may be necessary to combine a number of the avoidance techniques mentioned above. |
40302b05ed4b2215fa8843099dfaf1df | 102 754 | 6.8 Avoidance parameters | |
40302b05ed4b2215fa8843099dfaf1df | 102 754 | 6.8.1 Minimum avoidance bandwidth | This is the minimum bandwidth over which the UWB devices shall reduce their transmission power below the maximum avoidance level. The values for the minimum avoidance bandwidth are given in annexes A to C. ETSI ETSI TS 102 754 V1.3.1 (2013-03) 19 |
40302b05ed4b2215fa8843099dfaf1df | 102 754 | 6.8.2 Default Avoidance bandwidth | This is the default bandwidth for the avoidance operation. This bandwidth has to be protected in the case a DAA enabled UWB device does not implement an enhanced victim service bandwidth identification mechanism. The values for the default avoidance bandwidth are given in annexes A to C. |
40302b05ed4b2215fa8843099dfaf1df | 102 754 | 6.8.3 Maximum avoidance power level | The maximum avoidance power level is the UWB transmit power assuring the equivalent protection of the victim service. In the basic two zone model the maximum avoidance power level is equivalent to the NIM power level given in table 1. In the multizone model there is be a hierarchy of avoidance power levels associated w... |
40302b05ed4b2215fa8843099dfaf1df | 102 754 | 6.9 Switching to LDC | UWB devices having LDC and DAA implemented and operating in all or part of the frequency band from 3,1 GHz to 4,8 GHz may also switch on the LDC parameter set to avoid interference to BWA services and radio navigation services as shown in table 4. Table 4: LDC limits LDC parameter Value Maximum Tx on ≤ 5 ms Minimum Mea... |
40302b05ed4b2215fa8843099dfaf1df | 102 754 | 7 Test considerations | |
40302b05ed4b2215fa8843099dfaf1df | 102 754 | 7.1 General considerations | Any test must verify that the UWB device can detect a victim service and react within a specified time. Therefore the tests must be able to measure the detect and avoid times and the chosen avoid options. As far as possible tests shall be representative of the normal deployment of UWB devices which may be static, walki... |
40302b05ed4b2215fa8843099dfaf1df | 102 754 | 7.2 Considerations for radio location services | A set of representative test patterns, simulating the full set of operational modes of radio location services will be specified. These patterns will use a combination of radar signal parameters such as pulse repetition interval, pulse width, modulation, bandwidth or burst repetition frequency. NOTE: This is comparable... |
40302b05ed4b2215fa8843099dfaf1df | 102 754 | 7.3 Considerations for BWA services | The peak and average power of a BWA system based on OFDM is governed by the number of subcarriers and not the individual carrier modulation. In this case the use of a specific modulation scheme emulating the victim signal for test is assumed not to be critical. During test the emulated victim signal must have the same ... |
40302b05ed4b2215fa8843099dfaf1df | 102 754 | 7.4 Maximum allowable measurement uncertainty | The measurement uncertainty for the measurement of each DAA parameter shall be defined. Measurements shall be repeated in order to determine an adequate detection probability with acceptable uncertainty for the selected victim signals. The reliability of the decision process in comparing the zone thresholds with the me... |
