When compared to the constant lubrication problems associated with chain drives, or the mechanical problems and high costs associated with gear drives, belts are the most cost-effective, reliable means of power transmission. However, optimum belt drive performance requires proper maintenance. The potential for long service life is built into every Gates belt. When coupled with a regularly scheduled maintenance program, belt drives will run relatively trouble-free for a long time.
Locating fault equipment
If BSC has fault, usually it will affect some Sites or all of Sites
If BTS has fault, usually it just affect itself and the handover success rate of adjacent cells
During implementation or expansion, we can “Interchange ” BTS and judge whether the fault is because of BSC or BTS
During maintenance, BSC faults don’t just affect one BTS
Aging U.S. Air Force fleets have deterioration problems, resulting in increased maintenance workloads. Nowhere are those increases more troubling than in the workloads associated with programmed depot maintenance (PDM), which can be significant, requiring 2,000 to 50,000 labor hours. RAND developed the PDM
