WiMAX Range and Throughput Experiment and Measurements

3:40pm

Columbia University (1770) PI: Henning Schulzrinne, Sung-Hoon Seo and Jan Janak:
3:40pm
Four slides: Base Station configuration; range and throughput experiment configuration; Mobile Station code/script; measurement results and conclusions

Polytechnic Institute of NYU (1751) PI: Thanasis Korakis
Four slides: Base Station configuration; range and throughput experiment configuration; Mobile Station code/script; measurement results and conclusions

UCLA (1797) PI: Mario Gerla, Giovanni Pau
slides
Seeing 14Mb/s DL, 2 - 3 Mb/s UL; connect to vehicle up to 300 m; client always receives, but cannot always connect; helped by setting client IP address; windows client works better than Linux client.
Poster from demo session: [ poster]

Colorado: (1768) PI: Dirk Grunwald Univ. of Colorado, Boulder
Studying U Colorado private network, built by Airspan.
Starting data modeling using Anritsu MS2721B with WiMAX demodulator; acquiring propagation based model from Airspan deployment.
Reference: Airspan plan for U Colorado slides.
Reference: MS thesis on "Field Study of WiMAX Performance"

UMass Amherst (1731) PI: Mark Corner, Brian Lynn
NA Issue: Would like coverage to downtown Amherst, 1 mi away; can this be done?
Issue: Can antenna be moved outside of bus for better range? Check with how UW Madison puts antennas on buses.

Wisconsin (1724) PI: Suman Banerjee and Derek Meyer:
Using dongle with Windows 7 PC; seen RSSI from -40 dbm down to -60 dbm; have seen connectivity up to 300 yds.
Existing Cisco system: Connectivity to buses, equipped with large client antenna, up to 500M, for coverage over 1.25 sq mi.

BBN Technologies, Cambridge MA Hamed Soroush, Manu Gosain and Harry Mussman:
slides
Range and throughput experiment uses script in mobile station and server behind base station to evaluate connection with ping and iperf. Seeing good throughput (up to 14Mb/s DL and 1 - 2 Mb/s UL) to 0.25 mi, but not yet further. Soon, will vary BTS and iperf parameters to see if can find a set for greater distances at lower rates. Do not expect range beyond 0.6mi.

Local Experiments and Experimenter Support

Have established an experiment exchange and experimenter mailing list, at http://groups.geni.net/geni/wiki/WiMAXExper

MIT experiments, using BBN BTS: evaluate ARQ and HARQ changes to better support video streaming

Clemson experiments, using BBN and/or Rutgers BTS: evaluate DOS attack susceptibility

Two experiments being planned at NYU Poly: slides

Spiral 3 Roadmap

This roadmap shows the original and *current goals that apply to the GENI WiMAX projects:

Install and bring up WiMAX base station kit, including the ASN Gateway. (GEC10, or earlier)

Evaluate range and thoughput of WiMAX base station kit and Linux PC with Intel WiMAX modem card and/or mobile station used for for experiments. (GEC10, or earlier) (GEC11)

Install and bring up an instance of OMF/OML. (GEC10, or earlier) (*GEC11)

Operate and maintain the WiMax BS and the related GENI controller, using ORBIT Management Framework (OMF), with support for remote access by GENI users. (GEC11)

Present a mobility demo using WiMAX base station node, including the ASN Gateway, a Linux PC with Intel WiMAX modem card, or the dual-mode vehicular nodes, supporting both WiFi and WiMAX, required for your experiments, and a local instance of OMF/OML. (GEC10) (*GEC11)

Install and bring up experiment-controlled L2 (or OpenFlow) switch, to provide enhanced connectivity from the WiMAX testbed to the GENI backbone. (GEC11) (*GEC12)

Install and bring up Virtual Base Station (vBS)server, to support multiple simultaneous experiments (slicing) on the GENI WiMAX base station node. (GEC11) (*?)

Present mobility and/or application demos/experiments, showing support for multiple simultaneous experiments (slicing) of the GENI WiMAX base station node, and remote access by GENI users, utilizing experiment-controlled L2 (or OpenFlow) switch, and Virtual Base Station (vBS) server. (GEC11) (*?)
