Adnan Ghayas

Hi, I’m Adnan. I started Commsbrief in 2017 to make telecom concepts easier for professionals and businesses to understand. My goal has always been to break down complex topics, whether through blog posts, YouTube videos, or the training and consulting services I now deliver at Commsbrief Limited. For over 18 years, I’ve led product management, delivery plans, pricing strategies, and roadmaps for both new innovations and mature services in the telecommunications and media industries. In doing so, I’ve worked across a wide range of technologies, including mobile network systems, small cells, RF optimisation tools, mobile broadband, unified communications (UC), business tariffs, e-SIM, mobile video platforms, media boosters, cloud-hosted collaboration apps, TV apps, AI/ML integration, and AR-driven solutions for music and video. I’ve worked with leading mobile operators, vendors, and media companies, including Vodafone, Deutsche Telekom (T-Mobile), Ericsson, Telefónica O2, and Sky UK. My core strength lies in bridging the gap between technical capabilities and business outcomes—a focus I’ve carried into my work at Commsbrief, where I simplify complex telecom concepts for professionals and businesses. My journey has taken me to different parts of the world through living and working in Europe and Asia, and collaborating with teams physically and remotely in North America, Africa, and Oceania. This global experience allows me to adapt to markets with varying levels of maturity to deliver impactful solutions tailored to their needs. Through Commsbrief, I deliver training programs like the Business Case Masterclass and the Mobile Communications Masterclass, along with consulting services in mobile communications and business case development. My aim is to help professionals and businesses simplify complex challenges, work with clarity, and avoid unnecessary stress, so they can enjoy the work they do in high-tech industries.

4G vs GPRS: What is the difference between 4G LTE and GPRS?

4G and GPRS represent two different generations of mobile networks, and our mobile phones can access both to connect to the cellular network. However, while both 4G LTE and GPRS enable packet-switched mobile data, 4G is one of the latest cellular technologies, and GPRS is one of the earliest technologies. 4G is the fourth generation
