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 issue in draft legislation. This is an appropriate time to revisit the fundamentals: what a slice is at the protocol level, how 5G enforces quality […]

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 the choice as a per-configuration parameter. That’s a more interesting design decision than “5G moved to OFDM,” and it’s worth understanding why 3GPP declined to […]

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 limitations. First, smartphones transmit at much lower power than base stations, resulting in reduced uplink coverage compared to downlink. Second, higher frequencies experience higher path […]

One Network, Many Networks: How 5G Slicing Actually Works
July 5, 2026

The problem slicing solves A mobile network has always been a compromise. The same infrastructure must serve a surgeon monitoring a remote procedure, a teenager streaming 4K video, and a water meter reporting once a day. These use cases pull the network in opposite directions: one needs millisecond latency, one needs raw throughput, one needs […]

Beyond Speed: 5G Security Enhancements
May 24, 2026

When discussing 5G, most conversations focus on higher throughput, lower latency, and support for massive device connectivity. While these capabilities are important, one of the most significant advancements in 5G lies beneath the surface: security. As mobile networks advance from offering consumer broadband to enabling critical infrastructure, industrial automation, autonomous systems, and mission-critical communications, their […]
