Deployment Status (one slide from each campus)

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

Polytechnic Institute of NYU (1751) PI: Thanasis Korakis Thanasis:
Summary: slides
Status: Installed, working and using WiMAX RF AggMgr. Have complete range and throughput measurements; see below. Have started two additional experiments.

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.

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.

Mobile Stations

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


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.

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