    4242It should be noted that this license (experimental authorization) "is to be used for fulfilling the requirements of a U.S. government contract".
     
    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 supporting pole that mounts antenna and Base Station Outdoor Unit.  See Appendix 6 of [attachment:BS_INSTALLATION.pdf NEC Installation Manual dfor Base Station (IMN:BS)]
     65 * Capable of safely and securely supporting a pole that mounts antenna and Base Station Outdoor Unit.  See Appendix 6 of [attachment:BS_INSTALLATION.pdf NEC Installation Manual for Base Station (IMN:BS)]
    6666
    67 NOTE:  It is suggested that this process be started IMMEDIATELY, to assure that a license can be obtained.
     67 * Access to building ground, for lightning protection, using a heavy ground cable.
     68
     69 * 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.
     70
     71 * Secure access, to prevent unauthorized people from disrupting installation, or receiving electromagnetic exposure.
     72
     73NOTE:  It is suggested that this process be started IMMEDIATELY, to assure that an appropriate outdoor site can be identifed.

     77
     78An indoor site (e.g., an IT equipment room) should be identified on campus that meets these requirements:
     79
     80 * Equipment rack space to mount Base Station Indoor Unit.
     81
     82 * Equipment rack space to mount Linux Servers contained in kit, currently 3 servers.
     83
     84 * 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.
     85
     86 * Access to building ground, to ground equipment racks and mounted equipment.
     87
     88 * 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.
     89
     90 * 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.
     91
     92 * Access to backbone network Layer 2 connection.
     93
     94 * Secure access, to prevent unauthorized people from disrupting installation, or receiving electromagnetic exposure.
