    6363 * 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.
    6464
    65  * Capable of safely and securely supporting a pole that mounts antenna and Base Station Outdoor Unit.  See Sections 6.1 and 6.6 of the [attachment:BS_INSTALLATION.pdf NEC Installation Manual for Base Station (IMN:BS)]

    6666
    6767 * Access to building ground, for lightning protection, using a heavy ground cable.
     
    6969 * Access to Indoor Equipment Room, for power and fiber (signal) cables.  The use of a conduit is preferred, but otherwise the fiber (signal) cables must be mechanically protected.
    7070
    71  * Secure access, to prevent unauthorized people from disrupting operation, or receiving unhealthy electromagnetic exposure.  Section 1.7 of the [attachment:BS_INSTALLATION.pdf NEC Installation Manual for Base Station (IMN:BS)]

     79An indoor site (e.g., an IT equipment room) should be identified on campus that meets the requirements listed in Section 1.3 of the [attachment:BS_INSTALLATION.pdf NEC Installation Manual for Base Station (IMN:BS)], and particularly the following requirments:
     80
    8081
    8182 * Equipment rack space to mount Base Station Indoor Unit.
     
    8384 * Equipment rack space to mount Linux Servers contained in kit, currently 3 servers.
    8485
    85  * Access to Outdoor Site, for power and fiber (signal) cables.  The use of a conduit is preferred, but otherwise the fiber (signal) cables must be mechanically protected.
     86 * Access to Outdoor Site, for power and fiber (signal) cables.  The use of a conduit is preferred, but otherwise the optical fiber (signal) cables must be mechanically protected.
    8687
    8788 * Access to building ground, to ground equipment racks and mounted equipment.
    8889
    89  * Access to -48VDC feeds for Base Station Outdoor Unit (max 4A) and Base Station Indoor Unit (max 8.3A), or else -48VDC rectifiers run from 110VAC feeds.
     90 * Access to -48VDC feeds for Base Station Outdoor Unit (max 4A) and Base Station Indoor Unit (max 8.3A), or else -48VDC rectifiers run from 110VAC feeds.  See Sections 3.5 and 2.6 of the [attachment:BS_INSTALLATION.pdf NEC Installation Manual for Base Station (IMN:BS)] for technical specifications of the Base Station Outdoor and Indoor Units.
    9091
    9192 * Access to 110VAC feeds for Linux Servers, and possibly -48VDC rectifiers.  If possible, the 110VAC feeds should be protected with an  Uninterruptible Power Supply (UPS) that bridges short power gaps, to prevent disrupting the WiMAX testbed from the most common (short) power gaps.
