LTE Conformance and Regulatory Certification Introduction What is Conformance Test? Determine to what extent a product implemented based on a particular standard conforms to the individual requirements of the standard. Conformance Test EUT - Equipment Under Test Conformance Test System e.g. Agilent T4010S Test System e.g. LTE UE Page 3
LTE Conformance and Regulatory Certification Introduction Defining Conformance Specific set of tests performed: According to standards By an approved test lab (could be manufacturer s own) On an approved test platform Only devices that pass the tests can be released into the market All other types of tests are called pre-conformance or D&V Test Specs (TS..) - A set of test cases - Includes bands of operation - Constantly evolves, over releases Test Platform (TP..) - Approved test systems/tools /instruments - RF, PCT or RRM - Must keep pace with standards - Covers 80-90% of TS to be approved Validation - Done by test lab to approve test case implementation and test platform Page 4
LTE Conformance and Regulatory Certification Introduction Conformance Test Categories Regulatory Certification e.g. CE, FCC, Industry Certification e.g. GCF, PTCRB, CCF, etc. Certified Product Page 5

LTE Conformance and Regulatory Certification Introduction GCF Organization GCF (Global Certification Forum) Certification is defined and maintained by GCF members collectively. The Conformance and Interoperability Group (CAG) identifies the Certification Criteria (CC) through laboratory testing. Page 7

LTE Conformance and Regulatory Certification Introduction More LTE CA bands are ready for UE certification in GCF Page 9
LTE Conformance and Regulatory Certification Introduction PTCRB Organization PTCRB (PCS Type Certification Review Board) framework for GSM, UMTS and LTE UE certification services for North American operators. The PVG (PTCRB Validation Group) is a group of test laboratory organizations working in the field of PTCRB associated technologies. PVG works on open PTCRB RfTs (Request for Testing) and the validation of Test Platforms and Test Cases for the relevant PTCRB operating frequencies. Page 10
