There are currently two system profiles: one for Fixed WiMAX (IEEE 802.16d) and one for Mobile WiMAX (IEEE 802.16e-2005). Active profiles are those with ongoing certification testing and with announced certified products. Additional profiles have been defined to address the regulatory requirements of specific countries, and the demand from operators and vendors operating in these countries. Testing for these profiles can begin as soon as at least three vendors are ready to validate the new profile. Both Fixed WiMAX and Mobile WiMAX profiles are shown in Table 4.3. 4.6.2.2 Certification Modules The following six certification modules are included in the certification framework: Radio Conformance Testing (RCT) assesses compliance to the PHY layer. Protocol Conformance Testing (PCT) assesses the compliance to the MAC layer, including the Security Sublayer, the Media Access Control Common Part Sublayer, and the Service-Specific Convergence Sublayer. Interoperability Testing (IOT) or Mobile Interoperability Testing (MIOT) verifies interoperability within a test bed that includes base stations and subscriber devices from multiple vendors. Network Conformance Testing (NCT) assesses compliance above the MAC layer to test Internet Protocol (IP) layer signaling and messaging to and from the subscriber device. Radiated Performance Testing (RPT) provides PHY-layer metrics to determine over-the-air radio performance of subscriber stations (but not base stations), during normal operation, in the presence of near-field impairments due to objects (head, hands, desktop) typically found near the device. Infrastructure Interoperability Testing (IIOT) will focus on ASN
