The scope of work on this project is to leverage a commercial IEEE 802.16e WiMAX base station product to prototype an open, programmable and virtualizable base station node that could work over a metropolitan area and connect with off-the shelf WiMAX handsets and data cards. This includes the following steps: 1) Develop an open/virtualizable WiMAX base station with external control and data API’s. 2) Import a control framework from the Orbit project, and implement GENI-specific software on an external Linux-based PC controller for the WiMAX base station, demonstrating basic GENI compliance: virtualization, slice setup & resource management, L2/L3 programmability, and opt-in for off-the shelf terminals. 3) Integrate the GBSN with backhaul options to validate and demonstrate the total access networking solution, including VLAN connections to a GENI backbone network. 4) Demonstrate the GBSN capabilities in a phased manner, starting with controlled lab tests of each GENI feature and then migrating to a small-scale outdoor trial with off-the-shelf WiMAX terminal equipment. 5) Develop a deployment plan for multi-cell WiMAX services in GENI, including guidelines for site selection, frequency allocation, network backhaul and equipment/operating costs.
