Passive Optical Network (PON) technology is the backbone of modern fixed broadband, enabling high-speed fiber connectivity across residential, enterprise, and mobile backhaul segments. The PON market is undergoing a significant generational shift — from GPON’s widespread dominance to the rapid ascent of XGS-PON, with 25G and 50G PON emerging as the next frontiers. The PON […]

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 mobile network evolution for almost ten years.   DC started with LTE-Advanced, not 5G. Knowing this background helps explain why it is still one of […]

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 beyond who launched first. When you move from “who holds which bands” to “how many MHz they actually hold per band”, the competitive picture changes […]

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 something far more powerful. 4G LTE-Advanced Carrier Aggregation (CA), introduced in 2011 by the 3rd Generation Partnership Project (3GPP) Release 10, was designed to increase […]

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 starting to appear on some devices) represents 5G-Advanced — the next evolution of 5G. Some fundamental information 5G-Advanced (3GPP Release 18) builds on 5G with […]
