Full scale WiMAX Testbed for Multimedia Streaming

In full-scale testbed WiMAX base station, subscriber and ASN-GW hardware are procured form hardware vendors and only the application layer is built on top of it. Therefore some academia-industry consortia have ventured into this design path. The Global Environment for Network Innovations (GENI), a project sponsored by the National Science Foundation, USA is a collaborative initiative for academia, industry and the public for facilitating innovation in emerging global networks. The project leverages a commercial 802.16e base station from NEC, replacing the standard WiMAX controller with an open GENI software implementation that supports layer 2/3 programmability. This open GENI base station node (GBSN) device is intended to support programmability at both radio link and network routing layers via an open API, and will work with off-the shelf WiMax handsets and data. NEC Release 1, 802.16e base station product is selected for the development of GENI specific open programmability features.
