WiMAX Campus Deployment Coordination

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

Description

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

Attendees

BBN Technologies Harry Mussman, Manu Gosain
NEC Laboratories America Sampath Rangarajan, Rajesh Mahindra
WINLAB Ivan Seskar
Columbia Univ Sung-Hoon Seo, Jan Janak
Polytechnic Institute of NYU Thanasis Korakis
UCLA Giovanni Pau, two students
Colorado Dirk Grunwald
UMass Amherst Mark Corner
Wisconsin Derek Meyer

Agenda

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

Introductions

Deployment Status (one slide from each campus)

Columbia University (1770) PI: Henning Schulzrinne Sung Hoon Seo and Jan Janak: slides Waiting for contract approval and installation; hoping for early March.

Polytechnic Institute of NYU (1751) PI: Thanasis Korakis Thanasis: slides Installed and using WiMAX RF AggMgr.

UCLA (1797) PI: Mario Gerla, Giovanni Pau Giovanni: 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; isntalled WiMAX RF AggMgr, but not yet in use; will do range measurements by GEC10.

Colorado: (1768) PI: Dirk Grunwald Univ. of Colorado, Boulder

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.

Deployment Status Summary

On Feb 23:

Campus Who Indoors Outdoors Using Intel 6250 modem? Using WiMAX RF AggMgr? Access to GENI backbone? Comments
Columbia University Jan Janak Yes Hope for early March Yes x ? Indoor testing started; received info request from Clearwire
Polytechnic Institute of NYU Thanasis Korakis - Yes Yes Yes ? Working on mobile stations and measurements
University of California, Los Angeles Giovanni Pau - Yes Intel 5130 modem Installed, not yet using Campus via CENIC to I2 for Internet; $40k charge Outdoor testing starting
University of Colorado, Boulder Dirk Grunwald Yes Installation starting Monday x x Pricing campus tunnel to I2 Working with campus IT; outdoor testing started
University of Massachusetts Brian Lynn Yes Plan March 2011 Yes, with USB, under Xen x Requesting 2nd VLAN Facility plan revised; prelim shading analysis completed
University of Wisconsin, Madison Derek Meyer Yes Installation underway x x I2 is in next lab Plant mgmt to install on Waisman Ctr
BBN Technologies Manu Gosain - Yes Yes Yes I2, NLR Outdoor iperf testing underway
Rutgers University Ivan Seskar - Yes Yes Yes I2 Plan Bush Campus install by Feb 2011

Software Installation

Documentation and procedures (Manu Gosain) Review of process to move to new WiMAX RF AggMgr. slides Ivan: Also, includes ability to get, store and restore a full set of BTS configuration parameters.

WiMAX Range and Throughput Measurements, and Site Planning

Range and capacity at BBN (Harry Mussman, Tony Michel and Tom Cahill) Process 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.

Adding 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 http://groups.geni.net/geni/wiki/WiMAXExper (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?
