    43 === 7.1  Obtain FCC License ===
    44 
    45 Each campus must apply to the FCC and obtain a license (experimental authorization) to operate the WiMAX equipment at their location. 
    46 
    47 NOTE:  It is suggested that this process be started IMMEDIATELY, to assure that a license can be obtained.
     42=== 7.1  Identify Outdoor Site on Campus ===
     43
     44An outdoor site (e.g., the roof of a building) should be identified on campus that meets these requirements:
     45
     46 * 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.'''
     47 
     48 * 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 * Access to building ground, for lightning protection, using a heavy ground cable.
     50 * 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.
     51 * 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)]
     52
     53'''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.'''

     57=== 7.2  Obtain FCC License ===
     58
     59Each 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.'''
