There are subtle differences that many ignore.
Let me break it down for you.
In 4G, ECM-Idle means devices are on but idle.
5G’s CN-Idle wakes up faster.
It handles background tasks efficiently.
Less lag when you need a quick connection.
When connected, 4G offers stable data transmission.
5G goes further.
Ultra-low latency.
Higher reliability.
5G handles it better.
4G’s RRCIdle saves battery but reconnects slowly.
5G’s RRCInactive balances power and quick reconnection.
4G is simpler but less flexible.
Deregistered states differ.
In 4G, devices detach completely.
5G streamlines this.
Less downtime.
5G redefines connectivity.
But challenges remain.
Those will be discussed in some other post.
Thanks for reading.
