QCI 6 vs QCI 7: Google Fi's Edge Over Mint Mobile in Crowded Venues

---

Understanding QCI and Network Priority

QoS Class Identifiers (QCI) are a set of standards defined by 3GPP for LTE networks to prioritize traffic based on service needs. Each QCI is associated with a priority level, packet delay budget, and packet error loss rate, which together determine how traffic is handled during network congestion.

QCI	Priority Level	Packet Delay Budget	Packet Error Loss Rate	Example Services
6	6	300 ms	10⁻⁶	Buffered Video, Web Browsing
7	7	100 ms	10⁻³	Live Streaming, Gaming

Lower QCI values indicate higher priority, meaning that during congestion, traffic with a lower QCI is less likely to be throttled.

Google Fi vs. Mint Mobile: QCI 6 vs. QCI 7

Google Fi reportedly uses QCI 6 for its data services, which provides a higher priority compared to Mint Mobile's QCI 7. This difference in priority can lead to noticeable differences in data speeds during high-congestion events like concerts and sports games.

• Google Fi (QCI 6): Offers higher priority, resulting in faster data speeds and less throttling during congestion.
• Mint Mobile (QCI 7): Experiences more throttling and slower speeds as it is deprioritized compared to QCI 6.

Real-World Implications

In practical terms, a Google Fi user at a crowded concert may maintain usable data speeds, while a Mint Mobile user might struggle with slow loading times or even stalled connections. This is because QCI 6 traffic is prioritized over QCI 7, allowing Google Fi users to bypass some of the congestion that affects Mint Mobile users.
