Sponsored by the National Science Foundation Overview WiMAX Meso-Scale Deployment Integration Part of Spiral 2 Started Sept 2009 6 Universities (and a BBN site) –Columbia University –Polytechnic Institute of NYU –UCLA –University of Colorado at Boulder –UMass Amherst –University of Wisconsin –BBN Technologies

3. Sponsored by the National Science Foundation Goals To develop the University campus WiMAX testbeds To use an open source managerial software based on OMF that will allow researchers to remotely use the infrastructure and run experiments

4. Sponsored by the National Science Foundation Plan The WiMAX testbeds are based on NEC profile C Base Stations Rutgers University: –gets the Base Stations from NEC –Setup a server with the required software –Ship the “WiMAX campus deployment kits” to the rest of the campuses

5. Sponsored by the National Science Foundation Network Architecture

6. Sponsored by the National Science Foundation Plan The network architecture as well as the NEC hardware: –Enables the researcher to monitor and control some basic base station radio functions –The ASN gateway removes many high-level WiMAX functions and allows the researcher to implement their own –The ASN gateway includes slicing functions, to allow the base station and ASN gateway to be shared by multiple researchers at the same time.

7. Sponsored by the National Science Foundation Plan The other campuses: –Obtain FCC experimental licenses in the 2,5 – 2,6 band. –Work on the engineering issues to develop the toolkit (place for the BS setup, mounting of the antenna, etc) –Install the hardware –Setup the server –Test the setup –Do measurements –Do experiments

8. Sponsored by the National Science Foundation Current Status All the campuses have obtained experimental licenses All the campuses have installed their WiMAX development toolkits 4 of them are up and running in a regular basis 3 of them are running “in a lab environment” basis Experiments underway A parket demo in GEC 9 between Rutgers, Poly, NICTA showing a multi-site experiment that uses the WiMAX Campus testbed in Poly

9. Sponsored by the National Science Foundation9 The Poly WiMAX deployment The BS (server, IDU) have been installed in the network room of the Library in the ECE Dept Building (5 Metrotech Center) The outdoor parts (sector antenna, GPS antenna, ODU) have been installed on the roof of the ECE Dept Building (5 floor building) We have got 2 experimental licenses from FCC to operate the WiMAX BS for 2 years

10. Sponsored by the National Science Foundation10 Current Status The testbed is up and running since September 2010 in a regular basis WiMax connectivity on the nodes is tested using different devices such as Wimax Dongle, HTC EVO phones and Wimax laptops The signal levels are tested (RSSI and SINR) to map the coverage area around the campus Extensive throughput and delay measurements underway Video conferencing is tested using the HTC EVO 4G phones.
