Think of QoS (Quality of Services) as traffic management for data.
Just like emergency vehicles get priority on roads, important data gets priority in mobile networks!
(QoS Class Identifier)
- 4G QCI - The Classic Highway
9 Priority Lanes Only (QCI 1-9)- Voice Calls = Express Lane (QCI 1)
- Video = Fast Lane (QCI 2-4)
- Web = Standard Lane (QCI 5-6)
- Background= Standard Lane (QCI 7-9)
(5G QoS Class Identifier)
- 5G QCI - The Future Highway
Expanded to 79 Lanes!- Gaming = Ultra-Fast (5QI 67-79)
- Video Calls = Priority (5QI 1-2)
- Web = Standard (5QI 6-9)
(5Gβs Bridges)
- Network Slicing (5G Only)
Imagine having separate Bridges for: - a URLLC for Ultra-reliable
- a EMBB for High-speed
- a MMTC for IoT Devices
(Channel Quality indicator)
- CQI- Your Real-Time Road Conditions
Like a weather report for your signal- Scale: 1-15
- CQI 15 = Perfect Signal
- CQI 1 = Poor Signal
- Pro Tip: Your service picks its lane!
When you make a call, it automatically gets VIP treatment (QCI 1)
