    v46 v47  
    2121 * Wiring between sites, preferably in conduit.
    2222 * Zero to three Linux Servers, to accomodate desired final deployment configuration of the ASN-GW and ORBIT Mangement Framework software.
    23   * Ethernet switch for multiple VLANs.
     23 * Ethernet switch for multiple VLANs.
    2424 * -48VDC power supplies for Base Station Outdoor and Indoor Units.
    2525 * 110VAC feed for Linux Servers, -48VDC power supplies and Ethernet Switch.  Preferably,the 110VAC feed should be provided by a UPS that bridges at least short power gaps.
     
    3535An outdoor site (e.g., the roof of a building) should be identified on campus that meets these requirements:
    3636
    37  * 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.'''
    38   * 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)]

    3940 * Access to building ground, for lightning protection, using a heavy ground cable.
    4041 * 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.
    4142 * Secure access, to prevent unauthorized people from disrupting operation, or receiving unhealthy electromagnetic exposure.  For personnel safe area, see Sec 1.7 of the [attachment:BS_INSTALLATION.pdf NEC Installation Manual for Base Station (IMN:BS)]

    43 '''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.'''

    4851Each campus must apply to the FCC and obtain a license (experimental authorization) to operate the WiMAX equipment at their location.

    5255In 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.
     
    8386At the end of the application process, the applicant must [https://fjallfoss.fcc.gov/FeeFiler/login.cfm pay the $60 application fee].  The fastest method of payment is by credit card.

    85 '''NOTE: FCC has a site for [https://selafoss.fcc.gov/oetcf/els/index.cfm testing the application process]. '''

    8790Suggestions from Mark Corner on the application process:
     
    8992 * Write down any reference numbers, file numbers, confirmation numbers, correspondence numbers as you go.  Most of them can't ever be retrieved without calling someone.  And there a lot of them.
    9093 * The application website is very linear.  Meaning that you really can't go back and edit anything, look up anything you already did, or go backwards.

    9395Once application process is completed and assuming there are no issues with the particular location, FCC will issue a WIMAX license after 4-8 weeks.  It is best to keep checking the FCC database to see when the assignment has been made, because it appears that it takes a long time for the FCC to mail out confirmation of the assignment.
