3 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

4 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

5 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

6 LTE Conformance and Regulatory Certification Introduction When to Perform Conformance and Regulatory Tests? UMTS UE Development Regulatory & Conformance Production Introduction Design UE Regulatory Safety SAR EMC -RF OTA Field Trial / IOT Operator Acceptance Define Spec Define Test Plan GCF or PTCRB Conformance RF Test RRM Protocol USAT Audio RF Conformance System Keysight GS8800 & T4010S Protocol / RRM Conformance System Keysight T4110S & T4020S Page 6

7 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

8 LTE Conformance and Regulatory Certification Introduction Example: GCF Conformance Assessment Table Page 8

9 LTE Conformance and Regulatory Certification Introduction More LTE CA bands are ready for UE certification in GCF Page 9

10 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

11 LTE Conformance and Regulatory Certification Introduction PTCRB introduces more LTE CA TCs for validation Page 11

12 LTE Conformance and Regulatory Certification Introduction Regulatory Test Required by regional regulatory unit - CE (Communauté Européenne) - FCC (Federal Communications Commission, 美國聯邦通訊委員會 ) - NCC ( 國家通訊傳播委員會 ) - MIIT (Ministry of Industry and Information Technology of the People s Republic of China, 中华人民共和国工业和信息化部 ) Specification - EN (GSM/GPRS/EGPRS), EN Part 2/11(3G), EN Part 13(LTE) - FCC Part22/24/27(2G/3G RF), FCC Part 27/22/24(LTE RF) - PLMN01(2G)/PLMN08(3G) /PLMN10(LTE) 中華民國電信法規 - YD/T 2683/2684/2685/2686/2687/2688 Page 12

16 Regulatory Test Case Examples Receiver Blocking Characteristics Corresponding to 3GPP TS In-band blocking, Out-of-band blocking, and Narrow band blocking Measure of the receiver s ability to receive a wanted signal at its assigned channel frequency in the presence of an unwanted interferer Page 16

17 Regulatory Test Case Examples Receiver Spurious Response Corresponding to 3GPP TS Spurious Response Verifies the receiver's ability to receive a wanted signal on its assigned channel frequency under the presence of an unwanted CW interfering signal at any other frequency at which a response is obtained i.e. for which the out of band blocking limit as specified in sub-clause is not met.
