    v43 v44  
    4747
    4848 * High, to maximize range.  Since throughput and coverage of WiMAX systems are highly influenced by the antenna location, care should be taken that the antenna is mounted so that siginificant portion of First Fresnel Zone is clear of obstructions.  Ideally the antenna is mounted on the elevated structure providing clear line of sight to most of the intended coverage area. '''NOTE: antenna height is limited to 6 m above the roof of the building, unless specifically approved by the FCC.'''
    49  
    50  * Capable of safely and securely supporting a pole that mounts antenna and Base Station Outdoor Unit.  See Sec 6.1, 6.6 of the [attachment:BS_INSTALLATION.pdf NEC Installation Manual for Base Station (IMN:BS)] 
     49  * Capable of safely and securely supporting a pole that mounts antenna and Base Station Outdoor Unit.  See Sec 6.1, 6.6 of the [attachment:BS_INSTALLATION.pdf NEC Installation Manual for Base Station (IMN:BS)] 
    5150 * Access to building ground, for lightning protection, using a heavy ground cable.
    5251 * Access to Indoor Equipment Room, for power and optical fiber (signal) cables.  The use of a conduit is preferred, but otherwise the fiber (signal) cables must be mechanically protected.

    5554'''NOTE: It is suggested that this process be started IMMEDIATELY, to assure that an appropriate outdoor site can be identified and it's coordinates used for obtaining FCC Experimental License. Sites can also identify multiple locations and apply for multi-site license in case they plan to deploy more BSs.'''
    56 
    57 ISSUE:  Do we also need GPS receiver and antenna, per NEC documentation?  If we do not install it now, what might we be missing later?
     55 
     56Once an outdoor site has been identified, a GPS should be used to determine its coordinates, which will be required in applying to the FCC for a license.

    61 Each campus must apply to the FCC and obtain a license (experimental authorization) to operate the WiMAX equipment at their location. '''NOTE: It is suggested that this process be started IMMEDIATELY following the selection of outdoor location, to assure that a license can be obtained.'''
    62 
    63 ISSUE:  What situations are likely?  Where the university has a license?  What if they don't have a license?
     61Each campus must apply to the FCC and obtain a license (experimental authorization) to operate the WiMAX equipment at their location.
     62
     63'''NOTE: It is suggested that this process be started IMMEDIATELY following the selection of the outdoor location, to assure that a license can be obtained.'''
     64
     65In a few cases, the university will have an "Educational Broadband Services" license that can be used for this equipment, depending upon university policy.  In the other cases, an application must be made to use spectrum that is either available, or else reserved for commercial use (e.g., Sprint/Clearwire) that has not yet started.
     66
     67Per Ivan Seskar, Rutgers has obtained a license to operate at two locations (WINLAB and Bush Campus), utilizing spectrum reserved for commercial use by Sprint/Clearwire, that has not yet started.  Because of this:
     68 The Rutgers/WINLAB license states:  "Licensee must get consent from Educational Broadband Services and Broadband
     69Radio Services licensees in the immediate vicinity of the tests."   
     70 When Sprint/ClearWire stsrts commercial service in the area, Rutgers will have to shut down tier WiMAX base stations, or find other specturm that is avaialble.
     71 Furthermore, the license expires in 2 years, and can only be renewed with another application.
     72 
     73Suggestions from Tony Michel on the application process are at [http://groups.geni.net/geni/attachment/wiki/WIMXBBN/020810%20%20license-HOWTO.pdf  ]

     75 
     76 
     77 When might this be expected?
     78
     79This must be done at each site.  Could it be done for all sites by contacting Sprint/ClearWire on behalf of GENI?
     80
     81ISSUE:  What happens when Sprint/ClearWire stsrts commercial service in the area?  Must shut down?  When might this be expected?

    6483
    6584The person submitting the application needs to obtain either a personal or institution FCC Registration Number (FRN).  If one is not available, it can be obtained through  [https://fjallfoss.fcc.gov/coresWeb/publicHome.do FCC's COmmission REgistration System (CORES) registration].
