Defines a collation of industry experience of technical issues resulting from the presence of multiple PICCs in the field of a PCD. Also explains how resonance frequencies may shift, how individual PICCs may see a reduced field strength, how multiple PICCs load the PCD, how they may change the local modulation signal and how PICCs should manage their identities to aid support of simultaneous usage.
