Mark, Chair, IEEE WG, Jan. 2023)? 1999: 1st IEEE Project– Scope: PHY and MAC layer of the air interface of interoperable fixed pointtomultipoint broadband wireless access systems. The specification enables transport of data, video, and voice services. It applies to systems operating in the vicinity of 30 GHz but is broadly applicable to systems operating between 10 and 66 GHz.8 NDSLab Copyright2023IEEE Standards +1066GHz PHY211GHz PHYConformanceRevisionMobilityRevisionLicense ExemptMultihop RelayMIB (fixed) (mobile)Management10GHz PICS10GHz RCT10GHzTSS TP11Ghz PICSCoexistenceManagement Coexistence ConformanceAir Interface: finalized and published: under development GenerationWiMAX2Consolidate9 NDSLab Copyright2023?

WiMAX equipments are certified by WiMAX Forum after passing the certification tests of WFDCL (WiMAX Forum Designated Certification Laboratory)? Certification process includes Radio Conformance Test (RCT), Protocol Conformance Test (PCT), and Interoperability Test (IOT)? 46 CPEs and 35 BSs have been certified by WiMAX Forum (due Dec. 2023)CPEWFDCLBS全球市場11 NDSLab Copyright2023Plugfest? WiMAX論壇所舉辦之插拔大會 (Plugfest)是讓 WiMAX設(shè)備供應(yīng)廠商將其所開發(fā)之產(chǎn)品，在進行正式互通性測試之前，彼此間先進行互通互連預(yù)先測試的活動，以驗證是否符合標準的要求，並對產(chǎn)品作必要的修正以增進產(chǎn)品的互通功能。12 NDSLab Copyright2023IEEE vs. WiMAX Forum?
