The ETSI HiperMAN is commonly thought to be the equivalent of IEEE 802.16 (or WiMAX). In fact, it is the European version addressing spectrum access in ranges under 11 GHz. There is a second European standard emerging called ETSI HIPERACCESS that will define (mostly licensed uses) above 11 GHz (approximately). Since the Forum has committed to supporting and incorporating the HiperMAN standards into the overall WiMAX standard, interoperability should be a constantly addressed issue. The IEEE 802.16 standard covers spectrum ranges up to about 66 GHz inclusively. Complete ETSI standards can be downloaded at: ETSI Standards.
