5G is a deployed standards family, not a finished one. Its radio and core baseline is stable; current work concentrates on AI-assisted radio, Ambient IoT, satellite access, energy use and operational refinement.
This monitor tracks what 3GPP has standardized. It does not claim that every listed feature is enabled in every commercial network.
The 5G baseline is frozen in completed releases while 5G-Advanced continues to add normative features.
Current baseline
Values are only comparable when their definitions and evaluation scenarios match.
| Parameter | Current value | Definition and maturity | Evidence |
|---|---|---|---|
| Theoretical peak data rate | 20 / 10 Gbit/s Adopted | Downlink / uplink target under the evaluation assumptions in TR 38.913. Frozen specification | 3GPP 38.913 |
| Connection density | 10⁶ devices/km² Adopted | Massive machine-type communication target; this is not user density. Frozen specification | 3GPP 38.913 |
| Radio latency target | 1 ms Adopted | User-plane URLLC target under defined radio conditions, not general end-to-end latency. Frozen specification | 3GPP 38.913 |
| Basic waveform | CP-OFDM · CP-OFDM or DFT-s-OFDM Adopted | Downlink · uplink. The uplink can trade flexibility for lower peak-to-average power. Frozen specification | 3GPP 38.211 |
CP-OFDM in the downlink, CP-OFDM or DFT-s-OFDM in the uplink, scalable numerology and operation across sub-7 GHz and mmWave bands.
Current movement: Release 20 work is refining early channel acquisition, massive-MIMO reference signals and sounding rather than replacing the air interface.
LDPC protects user data and Polar codes protect most physical-layer control information.
A service-based core separates control and user planes, exposes network capabilities through APIs and supports slicing as a native architectural concept.
Current movement: Rel-20 work continues operational integration, charging resilience and exposure rather than replacing the 5GC baseline.
The Release 20 work supports up to 128 antenna ports, rank 4 and 19 subbands, with a standardized fallback quantization codebook.
Current movement: The data format is settled; the way a phone calculates channel quality remains contested.
Battery-constrained or battery-less tags reuse selected LTE and NR building blocks instead of introducing a fully separate radio design.
Current movement: PRDCH broadcast payload, interleaving, scrambling and repetition limits advanced; synchronization details remain open.
June 2026 plenaries
Phones entering connected mode will receive the early CSI configuration through SIB1; dynamic MSG4 parameters were rejected.
Antenna scale, report structure and quantization moved forward. Vendors still disagree over whether CQI needs one fixed calculation.
The design continues to borrow proven LTE and NR mechanisms; reader identity, timing and signal periodicity still require a decision.

5G and 5G-Advanced decisions represented across the June 2026 quarterly topics. Each published claim points to a specification, TDoc or the quarterly evidence set. Maturity and meeting outcome are recorded separately.
