WiMAX Campus Deployment Meeting

Thursday, March 17, 2011, 9:00am - 10:30am
Room: San Juan 5
Session Leader: Harry Mussman (GPO, Raytheon BBN Technologies)

This is a tentative agenda, and is expected to change.




The projects involved in deploying WiMAX base stations will review their current status and progress towards their Spiral 3 roadmap goals.

Deployment Status (one slide from each campus)

Columbia University (1770) PI: Henning Schulzrinne, Sung-Hoon Seo and Jan Janak:
Status: slides
Summary: Working indoors; ready to use WiMAX RF AggMgr. Waiting for contract approval and installation outdoors; hoping for early March.

Polytechnic Institute of NYU (1751) PI: Thanasis Korakis Thanasis
Status: slides
Summary: Installed; using WiMAX RF AggMgr. Completed basic range and throughput measurements; see below. Begun work on two additional experiments.

UCLA (1797) PI: Mario Gerla, Giovanni Pau Giovanni:
Status: slides
Earlier summary: Antenna on 10th floor, -5deg tilt; Windows laptop with USB-connected 6250; seeing 14Mb/s DL, 1 Mb/s UL;; connect to vehicle up to 230 m; done handoff WiMAX to WiFi; heavy rain doubled delay (why?) ; $40k to install link to I2; installed WiMAX RF AggMgr, but not yet in use.
Summary: Connected to vehicle up to 300M; client always receives, but cannot always connect; helped by setting client IP address; windows client works better than Linux client; seen throughput to 14Mb/s DL and 2 - 3 Mbs/ UL; done load tests with 4 of 11 Intel 5150 clients; done seamless integration with WiFi.

Colorado: (1768) PI: Dirk Grunwald Univ. of Colorado, Boulder
Status: slides
Summary: NEC BTS installed, and ready for turnup. Operating in A4/B4 block; also Clearwire; also U Colorado private network, built by Airspan. Starting data modeling using Anritsu MS2721B with WiMAX demodulator; acquiring propagation based model from Airspan deployment.

email from Dirk: We've changed the mounting location because we think the wind profile of the antenna makes the mounting system on top of the other building questionable. We regularly get 40-60mph winds this time of year.

We've already selected the new location. It's one of the two locations where our campus is installing their own WiMAX equipment. There is a spare pole & mount already in place, so that simplifies installation. We have to install the "IDU" in a weatherized metal enclosure. Installation starts next Monday. The parts have been ordered this week & installation is being done by our campus IT group and professional building maintenance people.

We also have a professional RF propagation survey done from this location. I've attached that as a PPT. This is for the (now) existing WiMAX system our campus has put up. Our antenna will be pointing due north. The existing propagation model doesn't include our system yet, and we're getting that done -- this will provide a model that we will calibrate using the signal analyzer and RF cards. slides

UMass Amherst (1731) PI: Mark Corner, Brian Lynn Brian: slides Have 6250 modem working with brick. Have data path working; have requested a second VLAN from IT.

Wisconsin (1724) PI: Suman Banerjee Derek Meyer: slides Have 6250 modem working. Installation in progress.

Spiral 3 Roadmap

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) (?)

WiMAX Range and Throughput Measurements, and Site Planning

Range and throughput at BBN (Manu Gosain, Tony Michel Tom Cahill and Harry Mussman, )

Experiment described in slides, including use of script in mobile station and server behind base station to evaluate connection with ping and iperf.

Latest results described in spreadsheet. Seeing good results to 0.2 mi, but not yet further. Expect to finish measurements by GEC10, and provide packaged experiment. Soon, will vary BTS parameters to see if can find a set for greater distances at lower rates. Do not expect range beyond 0.6mi.

Range and throughput at Univ Colorado (Dirk Grunwald)

Upgrade to new WiMAX RF AggMgr

Functions and procedures (Ivan Seskar and Manu Gosain)

Review of functionality; includes ability to get, store and restore a full set of BTS configuration parameters.

Review of process to move to new WiMAX RF AggMgr. slides

Add OMF/OML Capabilites

Upgrade to OMF/OML (case 2) required to support experimenters. (Harry Mussman and Manu Gosain)

Supporting Experimenters

Established an experiment exchange and experimenter mailing list, at (Harry Mussman)

MIT experiments, using BBN BTS

Clemson experiments, using ? BTS

Mobile Stations

HTC EVO handset (Giovanni Pau) Will get one in Europe, end of Feb, Vodaphone dealer, unlocked. How can we get more?
