[[PageOutline]] == 7. Campus Installation == === 7.1 Obtain FCC License === Each campus must apply to the FCC and obtain a license (experimental authorization) to operate the WiMAX equipment at their location. The 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]. With the FRN, an applicant can start the application process by filling out [https://fjallfoss.fcc.gov/oetcf/els/forms/442Entry.cfm Form 442]. Required information for filling up the form includes: * Frequency: [specify range near 2.5GHz] * Frequency tolerance: 0.00002 % * Power: 20 W * Radius: 5 km * Location: [use Google Earth/Maps to find out latitude/longitude of the location where you plan to install the antenna] * Emission designator: W7D * Contracting Agency: National Science Foundation * Contract Number: 0944089 It should be noted that this license (experimental authorization) "is to be used for fulfilling the requirements of a U.S. government contract". Each application should attach [http://groups.geni.net/geni/attachment/wiki/WiMAXInteg/CampusInstallation/113009%20v0.5%20GENIDandPInfraBuildouts.pdf a project overview, including details of NSF contract (award)] in the filing process. to increase the likelihood of license issuance and to expedite the process. At 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. NOTE: FCC has a site for [https://selafoss.fcc.gov/oetcf/els/index.cfm testing the application process]. Once application process is completed and assuming there are no issues with the particular location, after 4-8 weeks FCC will issue WIMAX license. Here is a sample license, the [attachment:Winlab-WiMax-License.pdf WINLAB Rutgers WiMAX license] received from the FCC. === 7.2 Identify Outdoor Site on Campus === === 7.3 Identify Indoor Equipment Room on Campus === === 7.4 Install Wiring Between Outdoor Site and Indoor Equipment Room === === 7.5 Install Pole at Outdoor Site and Ground === === 7.6 Install Antenna at Outdoor Site === [[Image(Antenna.jpg, height=160px, align=right)]] The base station kit includes one dual-polarization, omnidirectional antenna. 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. The installation should be performed by qualified PE to ensure proper grounding and should follow [attachment:ANTENNA.pdf NEC's mounting instructions]. === 7.7 Install Base Station Outdoor Unit === The Outdoor Unit (ODU) is mounted outdoors, near the antenna. It connects to the antenna with a coaxial cable, and connects to the Indoor Unit (IDU) with two fibers. In addition, it requires a -48 power feed and a protection ground. The installation should be performed by qualified PE to ensure proper grounding and should follow [attachment:BS_INSTALLATION.pdf NEC's installation instructions] === 7.8 Complete Wiring of Base Station Outdoor Unit === === 7.9 Install Indoor Equipment Racks and Ground === === 7.10 Install 120VAC and -48VDC Power Feeds and/or Supplies === === 7.11 Install Base Station Indoor Unit === The Indoor Unit (IDU) is mounted indoors, typically in an equipment room. It connects to the ODU with two fibers, and to the Linux servers usxing an ethernet cable. In addition, it requires a -48 power feed and a protection ground. The installation should be performed by qualified PE to ensure proper grounding and should follow [attachment:BS_INSTALLATION.pdf NEC's installation instructions] === 7.12 Complete Wiring of Base Station Indoor Unit === === 7.13 Initial Check-Out of Antenna and Base Station Outdoor and Indoor Units === === 7.14 Install Linux Server(s) and Software === === 7.15 Connect Backbone Network === === 7.16 Provide Reference Client Platform === === 7.17 Inital Check-Out of Campus WiMAX Testbed ===
