    156156=== 5.3  GENI WiMAX Kits ===
    157157
    158158As part of the Spiral 1 WiMAX D&P prject, two WiMAX campus deployment kits were purchased for:
    159  Rutgers, WINLAB[[BR]]
     159 Development kit at Rutgers, WINLAB[[BR]]
     160 Rutgers, WINLAB [[BR]]
     161
     162The following campuses/sites purchased their own kit:[[BR]]
     163  NEC Labs America [[BR]]
     164  Stanford [[BR]]
     165
     166The WiMAX Kit Project (1753) is purchasing and supplying WiMAX campus deployment kits to the following campuses.  In addition, it is providing a limited number of client platform kits.[[BR]]
    160167 Rutgers, Bush Campus [[BR]]

    162 The WiMAX Kit Project (1753) is purchasing and supplying WiMAX campus deployment kits to the following campuses.  In addition, it is providing a limited number of client platform kits.
    163  NEC Labs America [[BR]]
    164168 Columbia University [[BR]]
    165169 Polytechnic Institute of NYU[[BR]]
     
    168172 UMass Amherst[[BR]]
    169173 University of Wisconsin[[BR]]
    170  
    171 The following campus purchased their own kit;
    172  Stanford [[BR]]
    173 
    174 In addition, the following additional GENI-related campuses and sites may separately purchase the necessary equipment to build their own WiMAX campus deployment kits, and then deploy them with aid from the GPO and Rutgers WINLAB:
    175  BBN Technologies [[BR]]
    176  University of Wisconsin, 2nd site?  [[BR]]
    177  other?[[BR]]
     174
     175The following GENI-related campuses/sites are purchasing the necessary equipment to build their own WiMAX campus deployment kits, and then deploying them with aid from the GPO and Rutgers WINLAB:[[BR]]
     176 BBN Technologies, Cambridge, MA [[BR]]
     177 University of Wisconsin, 2nd site  [[BR]]
     178
     179The following campuses/sites have indicated an interest in obtaining their own WiMAX campus deployment kits:
     180 University of North Texas (Prof Kamesh Namuduri on 3/16)  [[BR]]
     181 Florida International University  [[BR]]
     182
     183Ray Raycaudhuir on 3/16:  Would prefer to get existing deployment underway, and then consider a 2nd round of kits beginning in 5+ mo.  [[BR]]
     184New kits would be Profile C  [[BR]]
     185Expect NEC would like to see orders for 40-50, if possible  [[BR]]

    179187=== 5.4  GENI WiMAX Licenses ===
    180188
    181 
    182 === Clearwire Deployments ===
     189Each GENI WiMAX campus/site must have a valid FCC license to operate a WiMAX base station.  In some cases, a campus/site plans to use an existing "educational license" already held by their institution.  However, in most cases, the campus/site plans to apply for and use a new "experimental license" that, by and large, can be obtained just by requesting it from the FCC.  This process has been successful in 4 cases for 3 campuses/sites.  [[BR]]
     190
     191However, in almost all situations, there is a potential overlap with the ongoing national Clearwire/Sprint WimAX rollout.  (See the list of current and planned deployments below.)  This is true for several reasons. [[BR]]
     192
     193If a GENI WiMAX campus/site plans to use an existing "educational license" already held by their institution, which has not yet been leased to Clearwire/Sprint, there is a reasonable chance that the institution may yet pursue a lease with Sprint/Cleariwre, and thus the GENI WiMAX campus/site could lose their license.[[BR]]
     194 
     195In the cases where the institution has leased their "educational license" to Clearwire/Sprint (which may or may not have started service), all is not lost.  A new upcoming rule apparently requires that an institution that has leased their "educational license" must retain "at least 5%" for their own use, or else forfeit their license.  So, a GENI WiMAX campus/site may gain partial access to an "educational license" even if it has alreasy been leased to Clearwire/Sprint.[[BR]]
     196
     197I the cases where a GENI WiMAX campus/site plans to apply for and use a new "experimental license", it has been found that most available spectrum has been leased to Sprint/Clearwire, although they are not yet using it in most locations (see below).  So, the FCC will grant an "experimental license" that overlaps spectrum already leased (likely to Clearwire/Sprint), but they require:  if the owner of the spectrum (i.e., Clearwire/Sprint) begins service, the holder of the "experimental license" must stop using the spectrum immediately.[[BR]]
     198
     199So, what does this all mean?[[BR]]
     200 1)  If a GENI WiMAX campus/site uses an "educational license" already held by their institution (or "5% of one", by the upcoming rule), they are OK (unless the institution decides to lease the license).[[BR]]
     201 2)  If a GENI WiMAX campus/site uses an "experimental license" that does NOT overlap a license holder, they are OK.[[BR]]
     202 3)  If a GENI WiMAX campus/site uses an "experimental license" that DOES overlap a license holder, they are OK UNTIL that license holder (i.e., Clearwire/Sprint) decides to start using that spectrum, and then they will have to shut down their WiMAX base station.  This is a significant concern in major metropolitan areas, per the deployment plans listed below.[[BR]]
     203
     204However, this could change.  An NSF effort is beginning to define a Wireless National-scale Test Bed (WiNTeB);  this could possibly affect the allocation of spectrum to national testbed uses. [[BR]]
