3LGCell Site Planning and DesignThis section provides information to assist in planning and designing an LGCell system and preparing a site for the LGCell installation. Proper project management is instrumental in providing a timely and accurate deployment.The first step in planning an LGCell system is to estimate the amount of radio frequency (RF) coverage you need for your building or coverage area. Initial estimates can be developed using floor plans and the models that follow. Eventually you need to go on-site to evaluate the facility’s readiness for installation and possibly perform RF measurements in order to guarantee performance. The LGC Wireless Site Survey Questionnaire is included for your reference.ContentsLGCell Site Planning and DesignProject Management . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3RF Coverage Estimate for a Site . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4RF Measurements and Site Survey . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7Site Survey Questionnaire . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7
3-2 LGCell Site Planning and Design
3-3Project ManagementInstalling the LGCell system is easy after all of the pre-installation requirements are met. It is beneficial to have one person manage and coordinate all aspects of the planning, design, and installation. Managing the process should avoid unnecessary surprises.The project manager is the person responsible for assigning tasks and ensuring scheduled work is performed on time. This includes collecting all information necessary for a complete site assessment, getting cost estimates and purchase order (PO) approval, scheduling any cabling work, scheduling the LGCell installation and commissioning, and providing final as-built documentation.The project manager also acts as the coordinator between the following people:Cellular or PCS carrierRF engineerSite acquisition personMBS vendorMBS installerCabling contractor(s)End userIf you do not have a designated project manager, please contact LGC Wireless. We can provide you with an estimate of what it would cost to have LGC Wireless manage your project. Please call us at 1-800-530-9960 (in the U.S.). International customers, please call us at +1-408-487-2400.

3-6 LGCell Site Planning and DesignOffice Antenna Coverage for 1800/1900 MHz Frequency ApplicationsThe preceding tables show estimated clutter-defined path loss slope (PLS) for different frequencies at various kinds of sites. If you change the design goal or other parameters, these numbers will change based on the PLS.If the design parameters (output power per carrier, design goal, antenna gain, and fade margin) differ from those stated above, you can use the PLS value shown in the preceding tables in the following formula to estimate the area of coverage per antenna:The PLS is a general path loss number which takes into account free space loss and normal barriers to the RF signal. Severe obstructions such as metal, cement walls, or elevator shafts are best accounted for by a physical site survey.

3-7As a reference the following table gives estimates of the signal loss for some RF barriers.Average Signal Loss of Common Building MaterialsRF Measurements and Site SurveyBefore designing an LGCell system, one should go to the site and measure the loss characteristics of the building. To determine the amount of coverage per antenna, the best method is a test of RF propagation, which you can do on-site with a test transmitter and field strength meter.While at the site, one can use the following Site Survey Questionnaire to document site specifics.Site Survey QuestionnaireYou can use the LGC Wireless Site Survey Questionnaire to help design your LGCell system. A sample questionnaire follows. The following information is needed when you walk a site:Partition Type Loss @ 815 MHzMetal wall 26 dBAluminum siding 20 dBConcrete block wall 13 dBFoil insulation 4 dBConcrete floor 15 dBSheetrock 1.4 dB
