    119The figure above shows a schematic representation of the WiMAX base station router and its connection to the rest of the network. As shown, the WiMAX base station is typically connected to a GENI access network with layer 2 switched connectivity using Ethernet or optical fiber technology.
     
    1513The second interface is the so-called R6+ interface by which the base station controller communicates with the base station hardware (which includes its own internal controller running a proprietary NEC operating system and control/management software). The R6+ interface exposes the hardware features such as assignment of MAC/PHY resources (i.e. OFDMA time-frequency slots, power levels, service classification, etc.) to each flow, as well as management interfaces for initial configuration, scheduler policy selection and queue management.

    2117The virtualized WiMAX Basestation Transceiver (BTS) system consists of different sets of APIs shared by components of the system. A brief overview of the interaction between different system components is as shown in the Figure 1.
