WiMAX Range and Throughput Measurements, and Site Planning

Columbia University (1770) PI: Henning Schulzrinne, Sung-Hoon Seo and Jan Janak:
Starting outdoor measurements; see ​Columbia measurements.
Measurements of RSSI and throughput show good campus coverage.

Polytechnic Institute of NYU (1751) PI: Thanasis Korakis
​slides
Throughput from 0.5 to 12Mbps; asymmetry on the uplink and downlink; many variations in urban area; sometimes significant packet losses even with good signal strength.
Have begun experiment to compare WiMAX and WiFi.
Also studying power meter reading application.

UCLA (1797) PI: Mario Gerla, Giovanni Pau
​slides
​slides
Measurement started with dual-mode vehicular node; 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.
Done handoff WiMAX to WiFi; heavy rain doubled delay (why?)
Using WINLAB script with improvements; will publish.
Have software to assess coverage on map: ​Radio Mobile for Windows.
Working with MIT group on network coding experiment over WiMAX/WiFi/Satellite.

Colorado: (1768) PI: Dirk Grunwald Univ. of Colorado, Boulder
Studying U Colorado private network, built by Airspan.
Reference: Airspan plan for U Colorado ​slides.
Starting data modeling using Anritsu MS2721B with WiMAX demodulator; acquiring propagation based model from Airspan deployment.
Goal: use drive-by measurements to create accurate coverage map with minimum effort.
Reference: MS thesis on "Field Study of WiMAX Performance"

UMass Amherst (1731) PI: Mark Corner, Brian Lynn
Installed on top of 17-story building, and on-the-air.
Both omni and sector antennas, manual switch; expect shading near building, but CS building not in shadow, approx 0.5 mi away.
Connecting from ? antenna to CS building, but not reliable.
Issues with connections immediately dropped; tried different BTS parameters; found that odu-noise_floor needed to be changed from 100 (which worked at BBN) to a lower value, i.e., 40 or 4; why?
Will soon deploy on x3 DOME busses; currently antenna will be inside of the bus.
Issue: Would like coverage to downtown Amherst, 1 mi away; can this be done?
Expect to use for experiments supporting MobilityFirst project.

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 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

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) (*?)
