Addressing the uplink challenge of 5G NSA requires more than adding spectrum
September 6, 2026

Most markets still rely on 5G Non-Standalone (NSA) as the main approach for commercial 5G. This setup allows operators to activate new radio (NR) capacity over an existing LTE core, […]

5G SA vs NSA: which one is actually better?
August 23, 2026

In my last conversation with a friend (not in the tech domain), he asked whether I should turn on 5G Standalone on my iPhone and whether I would notice a […]

Slicing Without Starvation: How 5G Polices Quality of Service Across Shared Spectrum
August 7, 2026

Network slicing is the key feature that validates the 5G Standalone core. However, if deployed on congested radio, it could disrupt the public internet. India’s telecom regulator has addressed this […]

Why Does 5G NR Support Two Uplink Waveforms? Understanding CP-OFDM and DFT-s-OFDM
July 26, 2026

The design question 3GPP actually faced LTE’s uplink was a single, non-negotiable decision: every PUSCH transmission uses SC-FDMA. 5G NR does not make that same trade-off unconditionally — it exposes […]

Supplementary Uplink: a practical solution for 5G’s uplink limitations
July 12, 2026

The uplink challenge is inherent to deployments that rely primarily on mid-band TDD spectrum. Most 5G capacity relies on mid-band TDD spectrum near 3.5 GHz, which presents three main uplink […]
