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 […]
Supplementary Uplink: a practical solution for 5G’s uplink limitations
One Network, Many Networks: How 5G Slicing Actually Works
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 […]
3GPP Release 18 and the Evolution of mmWave UE Performance
3GPP Release 18 introduces an important enhancement to millimeter-wave user equipment performance: support for more capable downlink reception in FR2 through simultaneous multi-beam operation. While this may not sound as […]
Dynamic Spectrum Sharing: The Architecture Behind 5G’s Accelerated Rollout
Dynamic Spectrum Sharing: A Proven Transition Enabler, Not a Long-Term 5G Strategy Dynamic Spectrum Sharing (DSS) emerged as one of the most pragmatic tools in the 4G-to-5G transition, offering operators […]
The 2025 Global Telecom Snapshot
The global telecom industry in 2025 presents a mixed picture of progress and imbalance. More people than ever are online, mobile broadband has become the norm, and 5G continues to […]
Dual Connectivity: The Technology That Made 5G Commercially Viable
Most people in the industry connect Dual Connectivity (DC) with 5G Non-Standalone (NSA) deployments. However, this view overlooks the long history and key role of DC, which has quietly supported […]
North Africa 5G: Who Has the Spectrum to Win?
As 2025 became the 5G launch year across North Africa (Tunisia, Egypt, Morocco, Algeria), I took a deeper look at spectrum holdings and allocations — and the story goes well […]
Carrier Aggregation in 4G vs. 5G — Why It’s the Backbone of Modern Mobile Networks
Carrier Aggregation (CA) combines multiple frequency blocks (Component Carriers) into a single larger channel, boosting speed, capacity, and coverage. It’s been around since 4G, but in 5G it’s evolved into […]
Have you ever seen “5G-A” or “5.5G” on your phone?
Have you ever seen “5G-A” or “5.5G” on your phone? Do you care about the icon… or only the experience you actually feel? That little 5GA logo (like the one […]
5G-Advanced (3GPP Rel-18) is moving from concept to implementation—but the device ecosystem is still early
5G-Advanced, standardized in 3GPP Release 18, is now shifting from “spec on paper” to real-world commercial rollouts. While operator deployments and feature roadmaps are accelerating, the device ecosystem remains in […]
5QI vs. QCI: The Silent Revolution in the RAN
Most people see 5G as higher throughput. However, Engineers see something deeper: the SDAP layer (Service Data Adaptation Protocol) — a new 5G protocol that fundamentally changes how QoS is […]
