Site Services & Quality Audit

A Site Audit Program is an approach to improve network performance in any given market. The objective is not only to solve current performance issues but also help identify changes that will permit permanently sustaining higher levels of performance. The Site audit process is focused on assuring that the performance of each site in the system is at a known, designed level.

GWS utilizes an experienced team of individuals and a highly integrated testing and analysis approach to bring a level of focus to these issues. At GWS, we are fully committed to our customer's objectives. Our intent is to provide specialized support and knowledge to each client. We will adapt our site audit procedures as required to meet a client's particular needs.

• The following describes the different disciplines and functions involved in the GWS Site Audit program:
  
• DC power supply system - perform rectifier and battery checks, including load tests of batteries.
  
• Grounding system - perform testing of site ground resistance, check ground routing practices, and that the integrity of all ground connections are in accordance with industry standards.
  
• Inventory - undertake a detailed inventory of all equipment including model and/or issue numbers, sufficient enough to identify and track any performance issues that may be related to specific vintages of equipment.
  
• Site layout - the dimensions of all equipment rooms and the physical locations of all equipment will be recorded on physical CAD layout drawings (Diagram 1), and front equipment drawings will developed for all equipment lineups.
  
• Antenna system checks and alignment - practices, procedures and acceptable performance thresholds will be established.
  
• Checks are made for proper antenna installation and both horizontal and vertical alignments are verified
  
• connector and jumpers are checked for moisture protection
  
• antenna system are swept and connectors torqued to appropriate levels
  
• GPS antenna locations - will be checked for adequate sky view.
  
• Equipment alignment procedures - all RF equipment at site is audited to ensure it meets specifications

GWS utilizes experienced personnel such as project managers, power and ground experts, as-built specialists, antenna service technician, test alignment engineers, and power system upgrade specialists to perform these tasks.

For efficiency, the GWS site audit process is broken into four general categories.

• The first category deals with the coordination and planning of the site visits.
• The second set of tasks deals with the actual testing of a sample set of sites.
  
• The third set of tasks evaluates the processes and procedures used for the sample set of sitesand utilizes the knowledge gained in the sample test to efficiently audit the remainder of the system sites.
  
• Finally, the last set of tasks evaluates the overall site audit process, and should provide guidance for modifications to processes that may be introduced for use in other markets for that client.
