Criteria 6.3 Distinct Identity
• Each IEEE 802 standard shall have a distinct identity. To achieve this, each authorized project shall be:a) Substantially different from other IEEE 802 standards.b) One unique solution per problem (not two solutions to a problem).c) Easy for the document reader to select the relevant specification.
