4.4 PATH DESIGN <br />4.3.1 When conducted by Motorola, path design services are based on formal field survey data <br />gathered under task 4.2. Path designs are considered final. The Project can move to the <br />implementation stage based on the recommendations within the final design report. Path <br />design Services include the following responsibilities: <br />4.3.3 In addition to warranty exclusions set forth in the agreement Motorola is not <br />responsible for excessive outages or degraded performance due to abnormal fading <br />conditions that include, but are not limited to: <br />• Formation of extreme radio refractivity gradients associated with: <br />• Exceptionally large temperature inversions, <br />• Abnormal temperature/humidity layers, <br />• Fog formation, <br />• Signal trapping caused by surface or atmospheric ducting; <br />• Reflections from unidentifiable off -path terrain features or physical structures; <br />• Rain fading due to rainfall rates that are more than the published rates or charts <br />used to predict rain induced outages; <br />If Motorola suspects abnormal propagation conditions are causing degraded system <br />performance, Motorola will reasonably assist Cabarrus County in verifying the <br />conditions leading to the degraded system performance. Ager the problem has been <br />identified, Motorola will support Cabarrus County in identifying possible solutions to <br />the problem, and assess the incremental improvement expected from corrective actions. <br />Implementation of corrective action required to remedy this type of problem shall be <br />the sole responsibility of Cabarrus County <br />The stated rain model applies for systems that are eight (8) gigahertz and higher. <br />Cabarrus County may request a copy of Motorola's path design model. <br />13-AugustM18 <br />® Motivate Solutions Confidential Restricted <br />Use or dMbsure dine proposal's subject <br />to the nabictbis on the cover page. <br />Tarso o/Contents vii <br />F-9 Page 202 <br />Select frequency band and capacity requirements for each path; <br />X <br />Determine antenna centerline heights based on Motorola's path clearance criteria; <br />X <br />Design paths to protect against ground-based reflections; <br />X <br />Select radio types, antenna sizes and types, power output, and protection scheme <br />required to meet Customer availability and capacity requirements; <br />X <br />Calculate path availability using industry acccpted models for predicting outages and <br />countermeasure improvements associated with normal atmospheric multi -path fading, <br />up -fading, rain fading and obstruction fading; <br />X <br />Submit a final path design report, including system maps, path profiles and availability <br />calculations. <br />X <br />4.3.3 In addition to warranty exclusions set forth in the agreement Motorola is not <br />responsible for excessive outages or degraded performance due to abnormal fading <br />conditions that include, but are not limited to: <br />• Formation of extreme radio refractivity gradients associated with: <br />• Exceptionally large temperature inversions, <br />• Abnormal temperature/humidity layers, <br />• Fog formation, <br />• Signal trapping caused by surface or atmospheric ducting; <br />• Reflections from unidentifiable off -path terrain features or physical structures; <br />• Rain fading due to rainfall rates that are more than the published rates or charts <br />used to predict rain induced outages; <br />If Motorola suspects abnormal propagation conditions are causing degraded system <br />performance, Motorola will reasonably assist Cabarrus County in verifying the <br />conditions leading to the degraded system performance.
