It can be reached by establishing a logical communication link (i.e. an association) between the reconfigurable mobile device and peer equipment. channel: designated part of the information transfer capability having specified characteristics, provided at the use

All Radio Applications (RAs) are called Unified Radio Applications (URAs)
