IEEE C63.27-2017 pdf free.American National Standard for Evaluation of Wireless Coexistence.
The wireless interfaces used for each wireless function shall be identified. The intended EM environment of the EUT shall be identified and the EM characteristics should be quantitied. Finally, the level of testing is determined based oti the test deliverables and the consequences of the FWP failure.
Coexistence testing can be similar for devices that use the same RAT Specific test guidance is provided in Annex A for common RATs.
Test methods supported by this standard are given in Annex B through Annex F. Each test method has different factors that influence the MU. MU shall be determined and documented for the coexistcncc test setup. Guidance to determine the MU of the coexistence testing is given in Clause 8. Uncertaiiity components shall be identified and quantified when they have the potential to affect the test results. Clause 9 identifies information to be included in coexistence tcst reports. Rationale for the approach and processes used in this standard is discussed in Annex F.
Coexistence testing shall be performed on the tinal deployable device. Evaluation of a radio module or subsystem that might later be integrated into a larger device can result in substantial inaccuracies for the coexistence estimation of the final product due to changes that can occur when a module or subsystem is integrated into a product.
An optional extension of the coexistence test results can be used in a risk assessment of the EUT. Clause 7 provides information regarding application of coexistence test results to risk management. Below is a (non. exhaustive) list of risk management!assessnlent documents that can be used for coexistence:
ISO l4971:2007andlSO/TR24971:2013
IEC TR 80001-2-2:2012
Another optional extension of the coexistence test results can be used to predict the LoC to gain an understanding of the field performance of the EUT. Determining the LoC requires quantified information on I) the probability distribution of the intended signal and its received signal quality, 2) the intended EM environment of the EIJT. and 3) coexistence test results of the FWP of the ELJT in the presence of unintended signals.IEEE 2030.1.1 pdf free download.
