Maintenance Problem found Consult documentation Choose maintenance vendor Who: end-user Goal: find the best company to meet the needs Activate internal installation and maintenance department OR Award contract to external vendor Who: end-user, NEM, crew Goal: award contract to vendor or allocate internal crew Visit site Problem evaluation Review documentation Who: end-user, crew Goal: narrow into the physical location(s) for repair needs Installation of on-site maintenance equipment Who: end-user, crew Goal: set-up the on-site test lab Run onsite tests on hardware and documentation Who: crew Goal: test base station for traffic, find interferences, losses, distance-to-fault in cables/connections Locate and repair Test network interconnection Drive test on software Review documentation Who: end-user, crew Goal: “make a call” functional test Optimization troubleshooting Update documentation Who: end-user, crew Goal: reiterate previous two steps until base station is functioning well Acceptance test of hardware and software Sign, update doc. Who: end-user Goal: verify KPI are met (< 2% dropped calls, for example) Go operational Archive documentaion Who: end-user Goal: restore traffic Who: crew Goal: replace hardware, reload software, reboot local units Who: crew, end-user, and NEM Goal: link base station to controller in switch room (central office) and start traffic Tests with spectrum analyzer and network analyzer Note: end-user is any user of a new wireless network to be installed Dedicated software Software, documentation, printing Full base station test Figure 2. The ﬂow of network maintenance routines, used as a main living document for multiple needs Installation Figure 3. Drivers in key installation and maintenance markets Sites and documentation are classified Highest accuracy and reliability in acceptance tests Fastest evolution of software and hardware Increase protection of data management Maintenance Super-fast maintenance procedures Preventive maintenance Constant data monitoring Increasing satellite/antenna accuracy Protection and classified issues Aerospace and defense Multiple technologies, challenging installation and maintenance procedures Base station becomes smaller, but more complex Operating frequency is getting higher More complex functional tests are needed More applications More cell maintenance More antennas in a single site Mobile Five- to seven-year replacement period Basic technology only, preference on desk-tops Low budget for repair General purpose Education Low-cost NEMs ESMOG environmental medical telemetry Palmtop terminals Emergency services Low-cost bundles Fast throughput in production at lowest up-front investments Longest warranty at best conditions Low-cost repair – extended warranty Agilent Measurement Journal 44
