Power customer satisfaction metrics. The formula below standardizes these inputs into a 0–100 scale, where 100 = flawless reliability:
    Reliability Score (RS) =
    *(0.4 × FCC Complaint Index) +
    (0.3 × Outage Frequency per 100 Subscribers) +
    (0.3 × J.D. Power Satisfaction Score)*
    Where:
  • FCC Complaint Index = (Total complaints / Total subscribers) × 100 (lower = better).
  • Outage Frequency = Annual outages per 100 subscribers (source: AT&T’s Form 477 filings).
  • J.D. Power Score = 1000 – J.D. Power’s satisfaction score (scaled to 0–100).
    • Example Calculation (2023 Data):
  • FCC Complaint Index: AT&T received 12,500 complaints (vs. 1.5M subscribers) → 0.83.
  • Outage Frequency: 1.8 outages/year → 18/100.
  • J.D. Power Score: 680/1000 → 320/100.
    • RS = (0.4 × 0.83) + (0.3 × 18) + (0.3 × 32) = 15.19 (on a 0–100 scale, 15/100).

    Network Congestion Impact on Gaming, Streaming, and VoIP
