Each issue appears as a row in the table and includes the following fields:
688729 Return |
LabVIEW Communications reports back-end compile errors on unchanged VIs.
It may be necessary to iterate this process until all back-end compile errors are gone.

527925 Return | High packet error rate for MCS 9 with Subcarrier Format IEEE 802.11ac 40 MHz. When using the Subcarrier Format IEEE 802.11ac 40 MHz and MCS 9 (256-QAM and code rate 5/6), a high packet error rate may be observed. That outcome is related to the non-adaptive configuration of the LLR demapper noise coefficient. It might also be related to the general receiver performance. Workaround: You can lower the packet error rate by configuring the noise coefficient for the LLR demapper according to the actual channel conditions.
| |||||
506019 Return | RF performance degradation can be experienced on the high and low ends of the NI USRP RIO frequency range Close to the upper and lower limits of the NI USRP frequency range, there are degradations on the RF perfomance from the NI USRP device. For the 802.11 Application Framework, these degradations result in a noisy RX constellation even at high signal power levels. You can see the certain peaks in the subcarrier channel magnitude plot where the amplitude is usually flat. Workaround: Avoid using frequencies at the high and low endpoints of the frequency range.
