The future Air Traffic Management (ATM) concept shall be based on network centric operations, consequently on information sharing. In order to support such a vision not only a versatile and capable ground based communication network is necessary but also a network which includes the air to ground sub-networks which shall have sufficient capacity and capability. One such air to ground sub-network shall be established for the airport surface intended to be used by departing and arriving aircraft as well as by surface vehicles. This communication system is currently (2011) emerging and shall be called Aeronautical Mobile Airport Communications System (AeroMACS). AeroMACS shall be based on the IEEE 802.162009 standard (IEEE, 2009) and especially on the WiMAX ForumTM Mobile System Profile Specification rel1.0 v0.9 (WiMAX Forum, 2010). A draft profile has been developed and is being evaluated currently, e.g. in the EU research project SANDRA (SANDRA). The IEEE 802.16-2009 standard (IEEE, 2009) specifies the air interface of combined fixed and mobile point to multipoint broadband wireless access systems with the possibility to support different services. The standard specifies the Medium Access Control (MAC) and the Physical (PHY) layer, where the MAC is capable to support multiple PHY specifications applicable to a specific operational environment. Figure 1 depicts the protocol reference model of the IEEE 802.16 standard. The Service Specific Convergence Sub-layer (CS) accepts higher layer data protocol units (PDUs) via the CS service access point (SAP). Thereby, the CS classifies each higher layer PDU according to available policies and maps each higher layer PDU to a so called service flow identifier. The IEEE 802.16 standard provides multiple CS specifications in order to provide interfaces for a variety of higher layer protocols. The MAC Common Part Sub-layer (CPS) provides the core functionality for data exchange via the wireless medium. A separate security sub-layer is also available. Generally, the IEEE 802.16-2009 standard provides a large amount of options. Thereby, different options may fit better for certain use cases than others. Due to the large amount of options it is merely impossible to be interoperable among different vendors based on the sole standard. Additional documentation and specification is necessary. This task has been conducted by the WiMAX ForumTM. This group specifies so called "WiMAX profiles" where a selected set of options from the IEEE 802.16 standard is qualified for such a profile. The WiMAX ForumTM has been established in June 2001 and is an industry led nonprofit organization. The purpose of the WiMAX forumTM is to certify compatibility and interoperability of broadband wireless products based on the IEEE 802.16 standard. In such a
