This Recommendation analyses the electromagnetic compatibility (EMC) disturbance between different modules in converged terminal devices and defines a conducted test method. As more and more converged devices appear on the market@ this Recommendation will help the industry to analyse and reduce such disturbance. Furthermore@ this mutual-disturbance test can be used as one of the immunity test items listed in [ITU-T K.34] and [ITU-T K.48] to determine the level of performance degradation. This Recommendation only covers the EMC mutual-disturbance between the different modules in converged devices. Examples of such devices include: GSM/Wireless LAN converged devices@ WCDMA/Wireless LAN converged devices@ CDMA/Wireless LAN converged devices and GSM/CDMA converged devices.
