WiMAX Forum defines a list of test cases to use during the certification process for all equipment based on the same system profile.

1. 
   Certification Profiles
   

Certification profiles are instantiation of a system profile; that is, for each system profile there are multiple certification profiles. A certification profile is defined by three parameters:

• 
  Spectrum band (<11 GHz)
  
• 
  Channel width (size) (1.75–10 MHz)
  
• 
  Duplexing type (TDD or FDD)
  

All certified products fully interoperate with other products in the same certification profile that is tested under the same release, and is backward compatible with products tested under previous releases. The definition of certification profiles depends on the market and vendor demand, which in turn is linked to spectrum availability in different countries. Vendor interest is clearly a prerequisite for interoperability, as a minimum of three vendors are needed to initiate interoperability testing.
For 802.16-2004 system profile, five certification profiles have been defined as shown in Table 9.2 [2].
It should be noted that the certification profiles define classes of interoper- able equipment for testing purposes. The actual coverage of interoperability among various products will vary due to the fact that multimode BSs or SSs, may work at different frequencies or channel widths, or duplexing modes. For example, a multimode SS will interoperate with any BS that supports any of the certification profiles for which the SS is certified.
