Commsbrief Limited Official
Hi, I’m Adnan Ghayas!
I started Commsbrief a few years ago as a free resource to demystify wireless technologies—especially mobile communications—by explaining them in plain, simple English. This YouTube channel extends Commsbrief.com, offering fresh, insightful content for anyone looking to understand telecom better.
With nearly two decades of experience in telecommunications, I’ve led market-leading products and services for major mobile operators, vendors, and related companies. Over time, Commsbrief has grown into a trusted platform for simplifying complex telecom and ICT concepts.
Now, Commsbrief offers training and consulting services for telecom, ICT, and cloud industries. Whether it’s mastering business case development or simplifying the business side of mobile communications, my goal is to make complex ideas actionable and clear.
All content reflects my personal views and does not represent my current or previous employers.
