5G End To End Capacity & Performance

5G promises extreme throughput and high spectral efficiency.
In real deployments, these gains are often not realized — even under excellent radio conditions.

Our 5G End-to-End Capacity & Performance (EtE-C&P) analysis identifies why, by correlating transport behavior, protocol-layer dynamics, and radio efficiency into a single performance view.

Our Expertise

We provide vendor-agnostic 5G EtE-C&P analysis and optimization, covering:

  • Downlink and uplink throughput validation

  • Transport-layer behavior (TCP / HTTP / QUIC)

  • PDCP performance in 5G standalone and LTE+NewRadio Dual Connectivity

  • Spectral Efficiency evaluation under real traffic

  • Root-cause analysis across Core, RAN, Transport, Server and UE

 

Our focus is beside peak KPIs, also sustained, usable capacity.

Transport-Aware 5G Performance Analysis

We analyze how server behavior, congestion control, and retransmissions directly affect:

  • PDCP stability

  • Scheduler efficiency

  • Achievable throughput and Spectral Effieciency [bits/RE]

  • Available Ressource Elements are obtained considering all overhead and losses e.g. Reference Signals 

We identify critical PDCP failure modes such as:

  • Out-of-Window discards across MCG and SCG

  • Reordering timer expiry due to Out Of Sequence

  • Latency asymmetry between LTE and NR legs

  • Uplink NR to LTE leg switching because of low SINR

 

These losses occur above RLC/HARQ and are invisible to traditional radio KPIs — yet harmful for performance.

Spectral Efficiency as an End-to-End Metric

We evaluate spectral efficiency as a system outcome, not just a radio indicator:

Our analysis correlates:

  • MCS, CQI, transmission layers and rank

  • TCP/IP Traffic patterns and Physical Layer Indicators

  • Server-side behavior and transport dynamics

 

This reveals why:

  • Increasing parallel HTTP sessions does not always improve SE

  • Identical radio conditions can yield very different spectral efficiency

  • Server choice and TCP Flow Control alone can shift SE distributions significantly
