11 | 9 | The 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. |

15 | 13 | The 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. |
